At a glance
Common Caribbean flatfish encounters are usually small to medium bottomfish, often roughly 6–18 in; scale hooks and tackle to the individual fish.
Primarily shallow coastal, beach, estuary, flat or channel habitat; deeper channels and drop-offs may hold larger fish.
Early morning, late afternoon and lower-light periods are common starts; tide/current changes can outweigh the clock.
10 Caribbean areas
Know it
Spot it, size it up and learn its habits.
- Identification
Scrawled sole (Trinectes inscriptus) — field identification starting point: a strongly flattened bottomfish with both eyes on the same side of the head and camouflage suited to sand, rubble or reef-adjacent bottom. Confirm the exact species against the approved photo and scientific-name biology reference.
- Typical size
Common Caribbean flatfish encounters are usually small to medium bottomfish, often roughly 6–18 in; scale hooks and tackle to the individual fish.
- Maximum size
Most species in this group remain under about 2 ft, although exact published maximum varies by species.
- Diet
Often eats shrimp, crabs, small fish, worms or other inshore prey; exact diet varies by species.
- Behavior
Uses current lanes, troughs, mangrove/structure edges or flats to ambush or graze; movement often follows tide, bait and light.
Find it
Where, when and how deep to look.
- Where to find it
Found in Puerto Rico. Start in coastal channels, flats, beaches, sand/grass edges, passes or estuary mouths that match the species habitat, especially where current concentrates bait. Habitat reference: sand, mud, seagrass and rubble bottoms, often in shallow coastal water and along channel or reef edges
- Habitat
Habitat: not recorded yet.
- Depth
Primarily shallow coastal, beach, estuary, flat or channel habitat; deeper channels and drop-offs may hold larger fish.
- Fishing depth
Work sandy/muddy bottom, channel edges and patches beside reef/seagrass; keep the bait/lure close to bottom.
- Fishing environments
Water: marine and brackish.
- Best season
Use current local reports and legal rules; choose days with manageable wind and good water conditions instead of relying on one universal month.
- Best time
Early morning, late afternoon and lower-light periods are common starts; tide/current changes can outweigh the clock.
- Best tides
Moving water around points, cuts, passes and troughs is a common trigger; watch where bait is concentrated.
- 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.
Bait & gear
What to tie on and what to throw.
- Best bait
Shrimp, small crabs, sand fleas, mullet, sardines and cut bait are common inshore choices; match the bait to the species and bottom.
- Best artificial lures
Small bucktails, jigheads with soft plastics and small spoons are practical flatfish choices.
- Tackle setup
Start with a medium spinning rod, 10–15 lb braid/mono, 15–25 lb leader and a #1–2/0 hook or small jig; scale up for large tarpon/snook.
- Hook size
Roughly #1 to 4/0 is a common inshore bait range, scaled to bait and species; use stronger/larger hooks for tarpon-size fish.
- Line
8–20 lb line covers much inshore fishing; 20–40 lb is more appropriate around heavy cover or large tarpon/snook-class fish.
- Leader
10–30 lb fluorocarbon/mono is a common flats/inshore start; move to 40–80 lb around abrasive mouths, structure or large tarpon/snook.

Catch it
Step by step, from first cast to landing.
Step-by-step: how to catch it
- Start where the species is most likely to occur: sand, mud, seagrass and rubble bottoms, often in shallow coastal water and along channel or reef edges
- Rig for the habitat and current: Fish-finder/Carolina or light jig rig that keeps bait near bottom without excessive drag.
- Choose an offering that matches the fish and situation. Natural bait: Shrimp, small crabs, sand fleas, mullet, sardines and cut bait are common inshore choices; match the bait to the species and bottom. Lures/alternatives: Small bucktails, jigheads with soft plastics and small spoons are practical flatfish choices.
- Fish it with this starting approach: Sight-fish, drift, cast current edges, work troughs/channels or present bait near mangrove and structure edges where access is legal. Presentation: Keep the presentation natural with the current; avoid over-weighting in shallow clear water and lead moving fish rather than landing on them.
- Use timing and water movement as adjustments, not guarantees. Time: Early morning, late afternoon and lower-light periods are common starts; tide/current changes can outweigh the clock. Tide/current: Moving water around points, cuts, passes and troughs is a common trigger; watch where bait is concentrated.
- Fishing techniques
Sight-fish, drift, cast current edges, work troughs/channels or present bait near mangrove and structure edges where access is legal.
- Catch and release
Let it go quickly if you're not keeping it.
Clean & cook
Is it good to eat, and how to prepare it.
- Edibility
BigJoe does not classify Scrawled sole as a routine food species from the current source set. That is not a claim that it is poisonous; before eating, confirm exact identification, lawful retention, documented local food use and current public-health advisories.
- Table quality
Not a common food fish — most anglers release it.
- Cleaning
Ice it right away. Use a clean board and sharp knife; scale or skin only when appropriate, remove the viscera or fillet cleanly, trim damaged tissue/bloodline as desired, minimize warm-water exposure, and keep the edible portion cold. If the fish carries venomous spines, dangerous teeth or a toxin advisory, follow the safety warning before cleaning.
- Cooking suggestions
For routine cooked preparation, FDA seafood guidance uses 145°F (63°C) as the safe internal-temperature target for fish; flesh should be opaque and separate easily with a fork. Grilling, baking, broiling, steaming or pan-cooking can all work after the fish is positively identified, legally retained and cleared for applicable toxin/mercury advisories.
Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
Wet hands for release, use pliers/dehooker and watch for sharp gill plates, teeth or dorsal spines depending on species.
- Regulations
No species-specific size, bag or season limits are listed here.
- Conservation
Avoid needless kills and follow protected-species, area and season rules.
