At a glance

Typical size

Common crab size is best judged by carapace width; many species here are roughly 3–8 in across.

Depth

Bottom-dwelling shellfish occur on sand, mud, seagrass, reef or hard substrate depending on species.

Best time

Use daylight/visibility and safe tide conditions unless local rules and experience support another approach.

Spot it, size it up and learn its habits.

Identification: Shelligs crab (Callinectes ornatus) — field identification starting point: a broad-bodied crustacean with a hard carapace, five pairs of walking appendages and the first pair modified as claws. Confirm the exact species against the approved photo and scientific-name biology reference.
Typical size: Common crab size is best judged by carapace width; many species here are roughly 3–8 in across.
Maximum size: Large crabs can exceed 8 in carapace width depending on species.
Diet: Many bivalves filter plankton; grazing snails eat algae/biofilm, while some mollusks are predators/scavengers.
Behavior: Usually attached, buried or slow-moving on the bottom; distribution follows substrate, salinity and water quality.

Where, when and how deep to look.

Where to find it: Found in Puerto Rico. Start in the documented habitat and substrate for this species, then narrow the search using depth, current, structure and food activity. Habitat reference: Habitat: sand bottom, mud bottom and rivers and streams.
Habitat: Habitat: sand bottom, mud bottom and rivers and streams.
Depth: Bottom-dwelling shellfish occur on sand, mud, seagrass, reef or hard substrate depending on species.
Fishing depth: Search only legal collection areas and depths where the bottom can be inspected safely; closures and sanitary status matter more than a fishing depth number.
Fishing environments: Water: marine, freshwater and brackish. Habitat: sand bottom, mud bottom and rivers and streams.
Best season: Collect only during open legal/sanitary periods.
Best time: Use daylight/visibility and safe tide conditions unless local rules and experience support another approach.
Best tides: Low water or low current can improve access/visibility, but never enter exposed reef, surf or mudflat conditions unsafely.
Best weather / conditions: Choose sea state, wind and visibility that let you hold position and handle the fish safely. Avoid treating rough weather as a feeding advantage.

What to tie on and what to throw.

Best bait: Fish scraps, oily baitfish pieces or commercial crab bait are common in traps where traps are legal.
Best artificial lures: Not applicable.
Tackle setup: Gloves, lawful crab gear, bait, measuring device if required and secure container.
Hook size: Hook-and-line is not the default method; traps, dip nets or hand capture may be used only where legal.
Line: Not applicable.
Leader: Not applicable.

Step by step, from first cast to landing.

Start where the species is most likely to occur: Habitat: sand bottom, mud bottom and rivers and streams.
Rig for the habitat and current: Use a lawful crab trap, hand line or dip net configuration for the exact species/area.
Choose an offering that matches the fish and situation. Natural bait: Fish scraps, oily baitfish pieces or commercial crab bait are common in traps where traps are legal. Lures/alternatives: Not applicable.
Fish it with this starting approach: Set baited gear in good bottom habitat and tend it often. Presentation: Collection rather than presentation: avoid breaking habitat and return undersized/prohibited animals immediately.
Use timing and water movement as adjustments, not guarantees. Time: Use daylight/visibility and safe tide conditions unless local rules and experience support another approach. Tide/current: Low water or low current can improve access/visibility, but never enter exposed reef, surf or mudflat conditions unsafely.

Fishing techniques: Set baited gear in good bottom habitat and tend it often.
Catch and release: Let it go quickly if you're not keeping it.

Is it good to eat, and how to prepare it.

Edibility: Good eating — a common food fish where it's caught.
Table quality: Good table fare when bled, iced and cooked fresh.
Cleaning: Safety first: Claws can pinch or cut. Keep fingers away from the claws and control from a safe position. Keep live or freshly harvested crabs cool and clean according to food-safety guidance. Handle claws and sharp shell edges carefully; rinse exterior debris, cook or process promptly, and avoid cross-contamination from raw shellfish.
Cooking suggestions: Cook crab thoroughly until the meat is firm and opaque and the animal/product has reached a safe cooked state. Keep cooked crab separate from raw shellfish and refrigerate leftovers promptly.

Safety, rules and taking care of the fishery.
