    Tips on Identifying Common Legal Baitfish And Smelt

    images of baitfish to identify legal and illegal baitfish

    Harvesting Baitfish for Personal Use

    All inland waters (including rivers, streams and brooks) are open to the taking of baitfish for personal use unless designated "closed to the taking of live baitfish" (see Special Fishing Laws), with the following conditions:

    • Fishing license required – You must have a valid Maine fishing license to harvest baitfish for personal use. Baitfish may not be sold or harvested with the intent to sell without a bait dealer's license.
    • Label and tend your traps – Baitfish traps and holding cages must be labeled with the owner's name and address, and must be tended at least once every 7 days by the person who set them. Baitfish traps may only be used to harvest baitfish species, as defined. All other fish must be immediately released alive into the water from which they were taken. Note: It is unlawful to harvest rainbow smelt with a baitfish trap.
    • Trap specifications apply – Baitfish traps may not exceed 50 cubic feet in volume and must be fitted with rigid entrance or exit holes.

    Harvesting Smelts for Personal Use

    Unless closed by rule as indicated within the Special Fishing Laws, a person holding a valid Maine fishing license may:

    • Take rainbow smelt for recreational purposes by hook and line from inland waters that are open to fishing in accordance with bag limits established by rule.
    • Take rainbow smelt for recreational purposes only from the inland waters or portions of inland waters that are naturally free of ice with a dip net in the usual and ordinary way from noon to 2:00 a.m. in accordance with bag limits established by rule. Bag limits established by rule under this paragraph are for a 24-hour period, beginning at noon on a given day and ending at 11:59 a.m. the following day.

    A person may not take rainbow smelt with a dip net unless it meets the requirements listed under the dip net definition (Title 12, §12456). A dip net when used to take rainbow smelt in a tributary or within 100 feet of the mouth of a tributary must contain a rigid circular frame that is not more than 24 inches in diameter as measured at any point on the hoop and manually operated by a single person (Title 12, §10001-12-A).

    Fishing license required – You must have a valid Maine fishing license to harvest rainbow smelt for personal use. Rainbow smelt may not be sold or harvested with the intent to sell without a bait dealer's license.

    Importation of Fish Prohibited

    It is unlawful to introduce, import, or transport any live fish or fish gametes (including baitfish or smelts) into the State of Maine without a permit ((§12509). This law helps keep Maine's waters healthy by limiting the introduction of foreign fish diseases and parasites, exotic fish species, invasive plants, and other undesirable aquatic life that can irreversibly damage Maine's natural resources. Do your part by only using locally caught legal baitfis species when fishing in Maine.

    Storing Live Baitfish and Smelts

    You may not store or hold live baitfish or smelts in waters where the use or possession of live fish as bait is prohibited during the entire fishing season. This includes waters restricted to the use of artificial lures only, waters restricted to fly fishing, and waters where there are other prohibitions on the use of live fish as bait.

    Commercial Bait Dealer's License

    In order to harvest live baitfish and smelts for sale, or to buy and resell them, you must possess a valid bait dealer’s license (Bait Retail License, Bait Wholesale License, or Smelt Wholesale License). For more information on license requirements or how to obtain a license, contact MDIFW at (207) 287-8000 or visit the Bait Dealer's License page.


    That's what the illegal introduction of exotic species brings to Maine's waters.

    Some thoughtless individuals are attempting to destroy the future of Maine's native fisheries. These nonsportsmen illegally stock the type of fish they prefer to catch, without regard for the environmental havoc they inflict on the resource. Illegal stocking selfishly denies the people of Maine the right to decide what is best for our waters.

    Please help fight this serious problem.

    • It is illegal to transport live fish without a permit except legal baitfish or smelts.
    • It is illegal to dump unused baitfish into any waterway.
    • There is a $10,000 fine for a conviction of illegal stocking.
    • Always keep your ears and eyes open for those who are committing these senseless acts.
    • If convicted, the license revocation has increased from 1 to 5 years.

    To report information about an illegal introduction please call: 1-800-ALERTUS (253-7887)


    Maine Law prohibits the transport or possession of any invasive plant or plant parts on watercraft or equipment (including baitfish traps and nets) that could cause the plant or plant parts to enter waters of the state. It’s up to you to inspect boats and equipment and ensure Maine’s waters are free from all aquatic invaders, including invasive plants. Failure to clean your equipment between waters puts you subject to financial penalties and loss of equipment. Learn more!

    Aquatic Invasive Species

    Help us Keep it Maine: Protect our waters from aquatic invasive species

    Maine has some of the country’s most pristine and healthy waters, which support high-quality habitat for fish and wildlife as well as endless opportunities for outdoor recreation. On our inland waters, anglers can fish for native brook trout, Arctic charr, landlocked salmon, and lake trout, just to name a few.

    Unfortunately, Maine waters, as well as the fish, wildlife, and recreation they support, are threatened each year by introductions of fish, plants, diseases, and other aquatic hitchhikers that compete with and displace native natural communities.

    What can be done?

    Once an invasive aquatic species has established in a body of water, it is extremely difficult for it to be eradicated. These efforts are costly, often risky, and not always successful and introductions have the potential to change our natural places and the way we enjoy them forever.

    Therefore, prevention is key. So much of the spread comes from people simply enjoying the great outdoors. It’s our duty as those who enjoy using Maine’s waters to become informed, attentive, and accountable for our potential role in the spread of invasive species and to take steps to protect Maine’s waters.

    Do your part: Protect Maine Waters from Aquatic Invasive Species

    1. CLEAN

    • Clean off plants, animals, and mud from gear and equipment including waders, footwear, ropes, anchors, bait traps, dip nets, downrigger cables, fishing lines, and field gear before leaving water access.
    • Scrub off any visible material on footwear with a stiff brush.
    • Dispose of debris in a trash reciprocal or a responsible location away from the water.

    2. DRAIN

    • Drain water from the watercraft prior to entering a waterbody and when preparing to leave a launch site.
    • Maine law requires that prior to entering a water body and when preparing to leave launch sites, boaters must remove or open any devices designed for routine removal/opening (for example, hull drain plugs, bailers, live wells, ballast tanks) to encourage draining of areas containing water (excluding live bait containers). This must be done in a way that does not allow drained water to enter any inland water of the state.
    • Boats should NOT be drained on the boat launch ramp. Since the transfer of aquatic invasive species to new areas within a water body can worsen the infestation, especially in high traffic launch areas, the preferred practice is to prevent direct draining back into the water body even when leaving the water body.

    3. DRY

    • Dry completely before reuse.

    Under Maine law, you must immediately kill any fish that you decide to keep, and never transport any live fish (other than legal baitfish or rainbow smelt).

    Never introduce fish or fish eggs into any inland water, including private, small, artificially constructed ponds, without a permit. MDIFW does issue permits to allow for safe and appropriate private pond stocking. Applicants must show that the stocking will not create adverse risks to native species, and that fish will come from pre-approved and licensed private hatcheries.

    Make sure you are using legal baitfish species. See the Baitfish Information section for a quick guide to identifying legal and illegal species.

    Don't dump your bait! Properly dispose of unused baitfish on land or in the trash. Never release any live baitfish into a water body. Dispose of unused worms in the trash, not in the water or on land.

    Consider using non-felt soled boots to further reduce the risk of spreading aquatic invasive species. If you do use felt soled boots, thoroughly dry the boots and/or soak in a disinfecting solution before moving to another body of water.

    If you see or suspect someone is moving live fish, contact the Maine Warden Service immediately at 1-800-ALERT-US or report the offense at

    Fishing with Soft Plastic Lures

    O-rings and hooks with built-in retention devices such as twist locks and bait keepers help keep lures where they belong.

    Soft plastic lures are popular fishing tackle; and just like all other equipment, it’s your responsibility to properly maintain and dispose of them. Over the years, plastic lures have been improperly used and disposed of, consequently ending up on lake bottoms or in fish stomachs. Fish can ingest these lures off the bottom, and that can negatively impact their health. Soft plastic lures on the land or in the water also pose environmental concerns.

    Some lures end up in the water intentionally, while others fall off hooks unintentionally. Do your part to help keep Maine’s waters clean and fisheries healthy:

      1. Properly dispose of soft plastic lures

      There is no doubt, discarding soft plastic lures on land or in the water is littering and poses environmental concerns. Instead, dispose of used lures in a trash can or recycling canister. Several Maine boat launches offer bait recycling canisters, and many local fishing clubs and retailers also offer bait recycling programs.

      2. Secure your lure

      Simply putting a soft plastic lure on a standard J-hook is not enough to help ensure your lure will stay on and not end up in the water or the stomach of a fish.

      Secure your hook to help your lure stay where it belongs. Not only does this help preserve the quality of the fishery and water, but also saves you money from not losing lures and reduces time spent rebaiting.

      There are several ways and products available to secure your lure, here are a few:

      How to utilize O-rings

      O-Ring: Much like Zip Ties O-rings can also be used as a means of securing wacky rigged soft plastic worm baits. Companies such as Fattube, Lethal Weapon, O-Wacky, Yum, and Wacky Tool all create tools specifically designed to help anglers use O-rings on soft plastic worm baits.

      • Step 1: Choose soft plastic worm bait of your choice.
      • Step 2: Insert bait into applicator tube.
      • Step 3: Firmly holding bait in the applicator tube, slide the O-Ring down the tube and onto the bait. Slide the O-Ring to the middle of the bait.
      • Step 4: Slide hook under the O-ring, wedging it in-between the O-Ring and the bait. The o-ring should be tight enough on the bait as to keep it firmly in place on the hook.
      • Step 5: Cast and catch!

      Tips: Do not reuse the O-Rings.

      Other popular options:

      • Zip Ties: Zip Ties can be used in the place of a rubber O-Ring to firmly secure a wacky rigged soft plastic worm. Although the traditional wacky rig requires the hook to be pierced through the middle the bait, the use of a zip tie will extend the useable life of the bait while minimizing loss as instead of hooking through the bait, the hook will be slid underneath the zip tie, sitting between the tie and the bait. After setting the hook on a fish the bait will slide up and away from the hook but staying on the line. This allows the angler to continue using the bait even after many catches.
        • Step 1: Choose soft plastic worm bait of your choice.
        • Step 2: Chose zip tie in color that complements or matches color of bait.
        • Step 3: Firmly fasten zip tie to the center of the bait. Once tightened, cut off the excess so it is flush with the head.
        • Step 4: Slide hook under the zip tie, wedging it in-between the zip tie and the bait. The Zip tie should be tight enough on the bait as to keep it firmly in place on the hook.
        • Step 5: Cast and catch!
      • A hook with a twist lock or built-in bait holding device: Examples are Mustad Ultra point Impact soft plastic hooks or Owner Twistlock hooks. These are a bit more expensive than traditional hooks, but in the long run helps keep the bait on the hook and extends the life of the soft plastic.
        • Step 1: Screw the head of the plastic bait onto the device.
        • Step 2: Secure the opposite end of the soft plastic to the hook so the lure extends from the “screw” piece straight down to the point of the hook (sometimes referred to as a ‘Texas rig’).
        • Step 3: Cast and catch!
      • Bait stop: These small, durable pieces of rubber keep the soft plastic in place and prevents them from sliding down.
        • Step 1: Chose your soft plastic lure of choice and slide it onto the hook.
        • Step 2: Slide the bait stop onto the hook against the soft plastic.
        • Step 3: Cast and catch!
      • Heavy monofilament fishing line: Another method you can use to help keep the bait from not sliding down the hook shank and eventually causing the bait to easily fall off the hook is using a piece of heavy monofilament fishing line.
        • Step 1: Cut a piece of heavy line (40 pound test for example) about 3” or 4” long.
        • Step 2: Thread the plastic bait onto the hook.
        • Step 3: Impale the heavy fishing line through the plastic bait and into the eye of the hook and out the other side of the soft plastic lure.
        • Step 4: Snip the ends flush with the bait.
        • Step 5: Cast and catch!
      • Super Glue for Jig Trailers: Although many jigs now come with metal keepers that are designed to secure your soft plastic lure trailers, one simple extra step can increase their effectiveness.
        • Step 1: Choose your soft plastic lure to attach as a trailer.
        • Step 2: Slide your trailer onto the hook and secure the SPL by gluing to hook shank at points of attachment by slightly pulling the lure back and applying glue to the hook shank and then pulling the lure over the glued area of the hook shank.
        • Step 3: Cast and catch!

      3. Check your bait often

      Don’t risk it – If you think you can “get a few more casts,” just replace it!

      Soft plastic lures can wear out and get brittle, stretch, or rip, increasing the likelihood that they could fall off your hook. The best thing you can do to prevent that is inspect your soft plastic lure frequently. After catching a fish, make sure your lure is still intact. If it is worn or close to falling off, either replace it with a new bait, rehook it, or repair it. Technology has come a long way since plastic lures were first introduced, and many on the market today are made with more durable materials for a longer lifespan and have built-in lure retention devices.

      Remember, it is time to replace or repair your lure if:

      • The lure keeps sliding down the hook
      • The lure has a minor cut
      • The plastic is stretched or brittle
      • You have caught several fish and worked the lure over abrasive cover

      Frequently asked questions

      What is a soft plastic lure?

      Soft plastic lures have been growing in popularity over the last 20 years as manufactures have released a greater variety and selection. Soft plastic lures come in all different colors, shapes, and sizes, ranging from soft plastic worms and grubs to baitfish and frogs. The lures may come with hooks attached, or you may need to attach the hook yourself. Many anglers prefer soft plastic lures over hard-bodied lures due to their more natural feel.

      Are biodegradable lures safer to use?

      Not necessarily. Although some products are marketed as biodegradable, little compelling data supports these claims and they do not comply with existing national testing standards for testing biodegradability. In addition, the lure manufacturing industry has not developed their own standards for manufacturers promoting more environmentally friendly soft plastic lures.

      How do soft plastic lures impact the health of a fish?

      Fish readily feed on discarded or lost soft plastic lures found on the bottom of Maine’s waters. Limited research indicates some fish like bass can regurgitate plastic lures, but other fish like brook trout may not and since soft plastic lures do not readily decompose in fish or in the water, and they also tend to swell over time, their accumulation in fish stomachs may alter feeding behaviors and adversely impact fish health.

      I have never found a lure in the stomach of a fish, is this really a problem?

      Anglers commonly report catching fish that contain soft plastic lures. Soft plastic lures are most often found in lakes with bass, since they are a popular lure for bass fishing. Bass are found primarily in the southern and coastal portion of the state. An examination of 18,000 stomachs from fish by MDIFW revealed on average only 2% of the fish had soft plastic lures in their stomachs. However, some waters experience elevated rates of ingestion influenced by water clarity, bottom type, type of fish, and availability of other prey. Since soft plastic lures do not tend to decompose in water, they can accumulate.

      What is the Maine Department of Inland Fisheries and Wildlife doing to protect the state’s fisheries from soft plastic lures?

      The Department is committed to educating anglers on the environmental concerns related to soft plastic lures in the water and on the land, proper disposal of soft plastic lures, and steps to take to prevent unintentional loss while fishing. MDIFW’s goal is to significantly reduce the number of soft plastic lures ending up in Maine’s waters and land while keeping this popular fishing lure available to anglers.

      Why would anyone dispose of a lure in the water?

      Most anglers values Maine’s prized fisheries and would never intentionally litter in the waterways. However, some lures end up in the water due to unintentional loss while fishing. That’s why securing your lure and checking your lure frequently is so important.

      Where can I find devices to secure soft plastic lures?

      Most fishing supply stores that sell soft plastic lures also sell retention devices.

      Why am I still seeing soft plastics in fish?

      Even if all anglers begin to follow best practices on maintaining and disposing of soft plastic lures it will take a while before the lures that are already in the waterways are gone.

      Recreational Angling for Migratory Fish

      There are several species of migratory fish (such as shad, river herring/alewives, and striped bass) that are managed by the Maine Department of Marine Resources and may be found in the inland waters of Maine. Complete information on recreational angling regulations for these species, and others, can be found by visiting or by contacting the Maine Department of Marine Resources, 32 Blossom Lane, 21 SHS, Augusta, ME 04333-0021, (207) 624-6550.

      Maximum length limit on Landlocked Salmon and Brown Trout: 25 inches

      Sea-run Atlantic salmon occur in many of Maine’s inland waters where landlocked Atlantic salmon and brown trout may also exist. Sea-run salmon are listed as endangered by the U.S. Fish and Wildlife Service and therefore may not be fished or harvested. Sea-run salmon exhibit a variety of color phases from black to silver to brown, and can look similar to brown trout and landlocked salmon in coloration. Therefore, establishing a 25 inch maximum length limit (S-33) on waters where adult sea-run Atlantic salmon may occur ensures anglers will not inadvertently “take” a misidentified endangered fish. Any sea-run Atlantic salmon incidentally caught must be released immediately, alive and unin-jured. At no time should sea-run Atlantic salmon be removed from the water.

      Freshwater Fish Safe Eating Guidelines

      For more information visit the Maine Center for Disease Control and Prevention website:

      Mercury in Fish Guidelines

      Warning: Mercury in Maine freshwater fish may harm the babies of pregnant and nursing mothers, and young children.

      It's hard to believe that fish that looks, smells, and tastes fine may not be safe to eat. But the truth is that fish in Maine lakes, ponds, and rivers have mercury in them. Other states have this problem too. Mercury in the air settles into the waters. It then builds up in fish. For this reason, older fish have higher levels of mercury than younger fish. Fish (like pickerel and bass) that eat other fish have the highest mercury levels.

      Safe Eating Guidelines: Mercury

      Pregnant and nursing women, women who may get pregnant, and children under age 8

      DO NOT EAT any freshwater fish from Maine's inland waters.

      Except, for brook trout and landlocked salmon, 1 meal per month is safe.

      All other adults and children older than 8

      CAN EAT 2 freshwater fish meals per month.

      For brook trout and landlocked salmon, the limit is 1 meal per week.

      Small amounts of mercury can harm a brain starting to form or grow. That is why unborn and nursing babies, and young children are most at risk. Too much mercury can affect behavior and learning. Mercury can harm older children and adults, but it takes larger amounts. It may cause numbness in hands and feet or changes in vision. The Safe Eating Guidelines identify limits to protect everyone.

      PFAS in Fish Guidelines

      Fish tested in several locations found levels of per- and polyfluoroalkyl substances (PFAS) above Maine CDC's recommended levels for regular consumption. Exposure to certain PFAS chemicals has been associated with:

      • changes in liver and kidney function,
      • changes in cholesterol levels,
      • decreased immune response to vaccines in children,
      • complications during pregnancy, and
      • increased risk of kidney cancer and possibly testicular cancer.

      Limit or eliminate consumption of all fish or certain fish species from the waterbodies listed in the table below.

      Safe Eating Guidelines: PFAS

      Additional Fish Guidelines: PCBS, DIOXINS, AND DDT

      • Fish caught in some Maine waters have high levels of PCBs, Dioxins or DDT in them.
      • These chemicals can cause cancer and other health effects.

      The Maine Center for Disease Control and Prevention recommends additional fish consumption limits on the waters listed below. Remember to check the mercury guidelines. If the water you are fishing is listed below, check the mercury guideline above and follow the most limiting guidelines.

      Regulating Harvest

      The rationale behind bag limits, bait restrictions, and other fishing regulations

      A brief history

      In North America, fishing regulations have been implemented for centuries, with season closures for some fisheries in place as early as the 1600s, and numerous fish harvest statutes enacted during the 1700s. By 1900, season closures and creel limits were common, though often those were the only regulations in place. Since the 1960s, though, regulations have increased, with a broad trend toward restricting both the number and the length of fish that can be harvested. In the Maine, water- and species-specific regulations are common, as are slot length limits and length-based creel limits.

      Why are there so many regulations?

      In Maine, fishing regulations are implemented for many reasons, including:

      • To protect native resources
      • To enhance fishing quality
      • To maintain healthy ecosystems
      • To control exotic species in certain waters
      • For public safety reasons (e.g. lead, mercury, PCB consumption advisories)
      • For social reasons (to accommodate the desires of individual user groups)

      Why do certain rules, such as catch and release, exist?

      We're scientists, so we don't mind questions! Here are some of the fisheries management techniques behind the regulations:

      General Law: This regulation provides a baseline level of protection to all waters. In Maine, the general law is essentially the default regulation, and from there exceptions to the general law are applied to individual waters.

      Low Bag Limits: Lower bag limits are intended to distribute the catch over a longer period and among more anglers. Low bag limits usually coincide with restrictive regulations such as high minimum lengths.

      Slot Limits: These regulations are bound by the upper and lower length limits, with the intent of directing harvest to specific parts of a fish population while protecting others. A slot limit may be used to "thin out" smaller fish to allow remaining fish to grow faster, and enable large fish to be caught and released or kept. The protected size slot protects fish and allows them to continue to grow and reach a larger size class. This regulation's success depends on anglers — unless they harvest fish of a given size, the regulation does little for resource management.

      Catch and Release: This regulation is intended to return fish to the water alive, giving them the chance to grow larger and be caught again. This regulation can be effective on waters where natural recruitment and population size is very low and growth rates are excellent, or on waters where there is a strict need for conservation (imperiled or endangered species, for instance).

      Fly Fishing or Artificial Lures Only: These "terminal tackle" regulations are applied to reduce mortalities in released fish, and are often an effective and necessary companion to restrictive bag and length limits.

      No Live Fish as Bait: This regulation is typically applied to prevent establishment of unwanted bait populations in waters where they currently do not exist (often brook trout or Arctic charr waters), while still allowing the use of dead baitfish or artificial lures.

      Why do regulations vary around the state?

      If you've fished in different locations around Maine, then you may have noticed that the fishing regulations can vary widely. That's partially because, when implementing or altering fishing regulations and policies, our Fisheries Division uses both biological and social data.

      For example, whether you are in the Northern or Southern half of the state, there are different general law season dates, brook trout bag limits, and bass bag, and length limits for fishing in lakes and ponds. These two areas of Maine vary when it comes to the fish species present, quality of habitat, and human population density; and therefore, vary in management focus.

      When designing a regulation, we carefully consider the water body, location, water quality, species composition, and the desires of anglers. Then we regularly monitor for effectiveness . This ongoing process of developing, maintaining, and adjusting fishing regulations statewide is no easy task; but it's essential to the effective management of our fisheries – no two of which are exactly alike.
