At a glance
Typical catches are commonly about 6–24 in depending on the species and water body.
Freshwater lakes, reservoirs, rivers or canals; depth use varies strongly by species, cover and water temperature.
Early morning and late afternoon are reliable starting periods; shade and current can extend activity through the day.

Know it
Spot it, size it up and learn its habits.
- Identification
American eel (Anguilla rostrata) — field identification starting point: a freshwater fish whose exact body pattern and fin shape should be confirmed against the scientific name and approved photo. Confirm the exact species against the approved photo and scientific-name biology reference.
- Typical size
Typical catches are commonly about 6–24 in depending on the species and water body.
- Maximum size
Larger freshwater species in this guide can exceed 2 ft; exact maximum depends on species.
- Diet
diet varies by species and can include fishes, insects, crustaceans, algae, plants or detritus
- Behavior
Relates strongly to cover, current, water level and temperature; many feed along edges or structure.
Find it
Where, when and how deep to look.
- Where to find it
Found in Puerto Rico. Start in Puerto Rico reservoirs, rivers or canals where the species is documented, then focus on structure, shade, current breaks and bait activity appropriate to that fish. Habitat reference: Habitat: estuary, continental shelf and coastal waters.
- Habitat
Habitat: estuary, continental shelf and coastal waters.
- Depth
Freshwater lakes, reservoirs, rivers or canals; depth use varies strongly by species, cover and water temperature.
- Fishing depth
Start around shoreline cover, drop-offs, current breaks or visible bait and then adjust deeper as light/temperature changes.
- Fishing environments
Water: marine, freshwater and brackish. Habitat: estuary, continental shelf and coastal waters.
- Best season
Use local water level, clarity and temperature as the primary seasonal clues.
- Best time
Early morning and late afternoon are reliable starting periods; shade and current can extend activity through the day.
- Best tides
Tide is usually irrelevant inland; focus on river/canal current, inflows, wind-driven bait and water level.
- 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
Worms, insects, shrimp, small baitfish or cut bait are common freshwater choices depending on species and local rules.
- Best artificial lures
Small jigs, soft plastics, spinners, crankbaits and topwaters cover most common freshwater situations.
- Tackle setup
Medium-light spinning rod, 8–10 lb line, 8–12 lb leader and a #4–1/0 hook or small jig is a versatile start.
- Hook size
About #6 to 2/0 covers many freshwater species; catfish and larger predators may need larger/stronger hooks.
- Line
4–12 lb line is a common light/medium start; use 15–30 lb around heavy cover or larger fish.
- Leader
Often 6–15 lb mono/fluoro; heavier leader is useful around abrasive cover or toothy fish.
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: Habitat: estuary, continental shelf and coastal waters.
- Rig for the habitat and current: Float rig, Carolina/bottom rig, jig head or simple lure setup depending on depth and species.
- Choose an offering that matches the fish and situation. Natural bait: Worms, insects, shrimp, small baitfish or cut bait are common freshwater choices depending on species and local rules. Lures/alternatives: Small jigs, soft plastics, spinners, crankbaits and topwaters cover most common freshwater situations.
- Fish it with this starting approach: Cast cover edges, fish current breaks or work bottom/structure; change depth before changing locations completely. Presentation: Keep natural bait lively and lures close to cover; slow down when water is hot, cold or highly pressured.
- Use timing and water movement as adjustments, not guarantees. Time: Early morning and late afternoon are reliable starting periods; shade and current can extend activity through the day. Tide/current: Tide is usually irrelevant inland; focus on river/canal current, inflows, wind-driven bait and water level.
- Fishing techniques
Cast cover edges, fish current breaks or work bottom/structure; change depth before changing locations completely.
- 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
American eel has documented food use in the BigJoe catalog/source set. Freshness matters — keep it on ice, and watch for any toxin or mercury advisory.
- Table quality
People do eat this species. We don't have taste or table-quality notes yet.
- Cleaning
After positive identification, current freshwater-rule confirmation and any water-quality advisory check, chill the fish promptly. Scale or skin as appropriate, gut or fillet with clean tools, remove bones/bloodline as desired and keep the edible portion cold.
- Cooking suggestions
If legally retained from water without an applicable consumption advisory, cook fish to 145°F (63°C) under FDA seafood guidance; flesh should be opaque and separate easily. Frying, baking, grilling or steaming can be chosen by cut and texture.

Clean It & Choose Your Cut
Food safety: Food safety: keep seafood cold, prevent cross-contamination, wash hands and tools, and refrigerate promptly.
Recommended cuts
- Skin-on fillet
- Skinless fillet
- Whole cleaned fish
- Steaks for larger fish
Cleaning steps
- Keep the catch cold from the moment it is legally retained.
- Use a clean, stable cutting surface and a sharp dedicated fillet knife.
- Scale first if cooking the fish whole or keeping skin-on portions and the species has scales.
- For fillets, cut behind the gill plate toward the backbone, then follow the backbone toward the tail with controlled strokes.
- Trim ribs and remove pin bones where present; remove skin only if the recipe calls for it.
- Rinse only as needed to remove visible debris, then pat dry; keep the edible portion cold and cook or refrigerate promptly.
Anatomy varies by species. These are general finfish steps, not a species-specific anatomical guarantee.

Sushi & Japanese Raw/Cooked Options
A fully cooked fish roll with seasoned sushi rice, cucumber and scallion.
Cooked/seared fish served over seasoned rice with cucumber, scallion and sesame.
Eating it raw? Follow FDA raw-seafood safety advice — fresh off the boat isn't enough.
For raw slices, freeze the fish first or use very fresh, well-iced fish.
Stay safe & legal
Safety, rules and taking care of the fishery.
