What size and limit rules apply to crabbing in the Louisiana bayous in 2027?

Direct Answer

For recreational crabbing in Louisiana bayous in 2027, the Louisiana Department of Wildlife and Fisheries (LDWF) enforces a daily possession limit of two bushels per person (approximately 100–120 crabs per bushel, depending on size), with a minimum carapace width of 5 inches measured across the shell from point to point. Commercial crabbers face stricter limits: a vessel limit of 50 bushels per day during peak season (April–November) and 25 bushels per day off-season (December–March), plus a mandatory crab trap limit of 200 traps per license. All crabbers must use cull rings (1⅞-inch diameter) on traps to allow undersized crabs to escape, and no female crabs with eggs (sponge crabs) may be kept. These rules are enforced by LDWF agents and carry fines of $100–$500 per violation, with potential trap confiscation.

Size and Limit Rules for Louisiana Bayou Crabbing (2027)

Recreational Crabbing Limits

Recreational crabbers (those without a commercial license) are subject to the following specific rules in 2027:

• Daily possession limit: 2 bushels per person (about 200–240 crabs total). A bushel is a standard volume measure, not a weight—roughly 1.25 cubic feet.
• Minimum size: 5 inches carapace width (point to point). This applies to hard-shell blue crabs (*Callinectes sapidus*). Soft-shell crabs (just molted) have no minimum size, but you must keep them alive and in a separate container.
• Trap restrictions: Recreational crabbers may use up to 10 crab traps per person, but traps must be attended (checked at least once every 24 hours) and marked with the owner's LDWF license number on a buoy.
• No sponge crabs: Female crabs carrying eggs (visible orange or brown mass under the apron) must be immediately released unharmed.
• Season: Crabbing is open year-round in Louisiana bayous, but peak abundance is April–November.

Commercial Crabbing Limits

Commercial crabbers (holding a valid Louisiana Commercial Crab Fisherman License) face stricter, tiered limits in 2027:

• Daily vessel limit: 50 bushels during the peak season (April 1 – November 30), dropping to 25 bushels during the off-season (December 1 – March 31). This is a per-vessel limit, not per person—multiple license holders on one boat share the limit.
• Trap limit: 200 crab traps per license. All traps must be tagged with a unique LDWF-issued tag (cost: $2 per tag, non-transferable). Traps must have two cull rings (1⅞-inch diameter) on each chamber to release undersized crabs.
• Size limit: Same 5-inch minimum as recreational, but commercial crabbers can keep peeler crabs (pre-molt) and soft-shell crabs of any size, provided they are harvested legally.
• Reporting: Commercial crabbers must submit monthly trip tickets to LDWF (by the 15th of the following month) detailing harvest location, bushels, and bycatch. Failure to report can result in license suspension.
• Seasonal closures: LDWF may close crabbing in specific bayous (e.g., Lake Pontchartrain, Barataria Basin, Terrebonne Bay) if blue crab populations drop below threshold levels (monitored via annual trawl surveys). In 2027, no emergency closures are currently in effect, but crabbers should check the LDWF website before each trip.

Gear and Equipment Rules

All crabbers must comply with these gear regulations:

• Cull rings: Mandatory on all traps (recreational and commercial). The ring diameter is 1⅞ inches (measured inside diameter). Traps without functioning cull rings are illegal and subject to seizure.
• Buoy marking: Every trap must have a buoy (floating marker) with the owner's LDWF license number clearly printed (minimum 1-inch letters). Buoys must be bright orange or yellow for visibility.
• Trap spacing: Traps must be set at least 50 feet apart from any other trap (including other crabbers' traps). No trap may block navigable channels or boat launches.
• Bait restrictions: Only natural baits are allowed (fish heads, chicken necks, squid, etc.). No chemical baits or attractants are permitted.
• Trap retrieval: All traps must be pulled and checked at least once every 72 hours (recreational) or 48 hours (commercial). Abandoned traps (left more than 7 days) are considered "ghost traps" and can be removed by LDWF.

Enforcement and Penalties

LDWF enforcement agents (including Wildlife & Fisheries agents and Louisiana State Police) patrol bayous year-round. Penalties in 2027 include:

• First offense: $100–$250 fine plus trap confiscation (if gear violations). Undersized crabs or sponge crabs found in possession add $50 per crab (up to $500).
• Second offense: $250–$500 fine plus 30-day license suspension (recreational) or 60-day suspension (commercial). Trap tags may be revoked.
• Third offense: $500–$1,000 fine plus 1-year license revocation and possible criminal charges (misdemeanor).
• Commercial violations: Over-limit bushels (e.g., 55 bushels on a 50-bushel day) result in $10 per excess bushel fine, plus seizure of the catch (donated to food banks). Trap limit violations (e.g., 250 traps on a 200-trap license) cost $25 per excess trap and immediate removal.

How to Check Current Limits Before a Trip

Crabbing rules can change due to stock assessments or emergency orders. For 2027, follow these steps:

1. Visit the LDWF website: Go to www.wlf.louisiana.gov and click "Fishing" > "Saltwater" > "Crabbing" for the latest proclamation.
2. Call the LDWF hotline: 1-800-256-2749 (24-hour recorded update on closures and limits).
3. Check the "Louisiana Fishing Regulations" app: Available on iOS and Android, updated in real-time with GPS-based zone maps.
4. Contact your local LDWF office: For bayou-specific questions (e.g., Lake Verret, Atchafalaya Basin, Bayou Lafourche), call the Baton Rouge headquarters at 225-765-2800.

FAQ

What is the exact minimum size for a blue crab in Louisiana in 2027? The minimum carapace width is 5 inches, measured straight across the shell from the base of one lateral spine to the other (point to point). This applies to all hard-shell blue crabs. Soft-shell crabs have no minimum size, but you must keep them alive and separate.

Can I use a crab net instead of a trap in Louisiana bayous? Yes, you can use a dip net (hand-held) or crab line (baited line with a net) without a trap license. However, the 5-inch minimum size and 2-bushel daily limit still apply. Dip nets are common for catching crabs in shallow bayous like Bayou St. John or Bayou Barataria.

Are there any bayou-specific closures in 2027? As of early 2027, no emergency closures are in effect. But LDWF monitors blue crab stock annually. In 2026, Lake Pontchartrain had a 30-day closure due to low abundance. For 2027, check the LDWF website or call the hotline (1-800-256-2749) before heading to Terrebonne Bay, Barataria Basin, or Atchafalaya Delta.

How many crab traps can a recreational crabber use in 2027? Recreational crabbers may use up to 10 crab traps per person. Each trap must have two cull rings (1⅞-inch diameter) and be marked with the owner's LDWF license number on a buoy. Traps left unattended for more than 24 hours are considered "abandoned" and can be removed by LDWF.

What happens if I catch a female crab with eggs (sponge crab)? You must immediately release it unharmed back into the water. Keeping a sponge crab is a violation with a $50 per crab fine (up to $500). The fine doubles if you're caught with multiple sponge crabs. This rule protects the breeding population.

Can I sell my recreational catch to a restaurant or market? No. Recreational crabbers cannot sell their catch. Only licensed commercial crabbers (with a Commercial Crab Fisherman License and trap tags) can sell crabs. Selling recreational catch is a misdemeanor with fines up to $500 and potential license revocation.

Do I need a fishing license to crab in Louisiana bayous? Yes. Recreational crabbers (age 16 and older) need a Louisiana Basic Fishing License ($13 for residents, $30 for non-residents). If using traps, you also need a Recreational Crab Trap License ($10). Commercial crabbers need a Commercial Crab Fisherman License ($100) plus trap tags ($2 each).

Bottom Line

Louisiana bayou crabbing in 2027 is tightly regulated with a 5-inch minimum size, 2-bushel recreational limit (50-bushel commercial), and strict gear rules (cull rings, buoy marking, trap limits). Always check the LDWF website or call the hotline before your trip, as closures can happen with little notice. Follow the rules to avoid fines and help sustain the blue crab population for future seasons.
