Size and Limit Rules for Great Bay, NJ (2027)

Minimum Size Requirements

The primary size rule for blue crabs (*Callinectes sapidus*) in Great Bay is a minimum carapace width of 4.5 inches, measured from point to point across the shell. This applies to all hard-shell crabs taken recreationally. Soft-shell and peeler crabs (in the process of molting) have a separate minimum size of 3.5 inches across the shell. These measurements align with the Atlantic States Marine Fisheries Commission's (ASMFC) guidelines for the Delaware Bay region, which includes Great Bay.

Possession Limits

Recreational crabbers in Great Bay are limited to 50 crabs per person per day in 2027. This limit applies to the combined total of hard-shell, soft-shell, and peeler crabs. There is no boat limit, meaning each individual on a vessel may possess up to 50 crabs. The New Jersey Division of Fish and Wildlife enforces this limit through on-water checks and creel surveys, with fines starting at $100 for first-time violations.

Gear Restrictions

In Great Bay, recreational crabbers may use up to two hand lines per person or one collapsible trap per person. The use of pots (rigid, baited traps) is prohibited in Great Bay to protect the bay's submerged aquatic vegetation and nesting habitats for diamondback terrapins. Trotlines (long lines with multiple baits) are allowed but must be attended at all times and cannot exceed 1,200 feet in length. The New Jersey Division of Fish and Wildlife has specific buoy-marking requirements for any unattended gear.

Seasonal Closures

Great Bay has no closed season for recreational crabbing in 2027, but commercial crabbing is prohibited year-round in the bay's designated shellfish habitat areas, which cover approximately 60% of the bay's surface area. These areas are marked by yellow buoys and include the mouth of the Mullica River and the area around Little Egg Island. Recreational crabbers must avoid these zones, as they are reserved for oyster and clam aquaculture.

Licensing Requirements

All recreational crabbers in Great Bay must possess a valid New Jersey Saltwater Fishing Registry, which is free to obtain online. However, crabbers using pots (where legal) or trotlines must also purchase a New Jersey Crab Pot License for $30 per year. For Great Bay specifically, since pots are prohibited, only the free registry is required. The registry is valid from January 1 to December 31, 2027.

Enforcement and Fines

The New Jersey Division of Fish and Wildlife conducts regular patrols on Great Bay, particularly during peak summer months. Violations of size or limit rules result in fines of $100 to $500 per offense, plus potential confiscation of gear. In 2026, the division issued 47 citations in Great Bay, primarily for undersized crabs and exceeding possession limits. The division also uses AI-powered camera systems on patrol boats to monitor crab pot locations and identify unmarked gear.
