Source-reviewed guide. Evidence gaps are stated explicitly; regulations remain local.
Identification
Finlets behind both the second dorsal and anal fins; larger fish can have very long second dorsal and anal fins.
Where to find it
The documented Caribbean areas and their occurrence sources are listed below. Historic records do not establish present abundance.
Habitat
Oceanic water above and below the thermocline.

Fishing techniques
FAO documents longlines, purse seines, sport fishing. These include historical commercial or incidental catches; they are not ranked as best or assumed legal locally.
Step-by-step: how to catch it
- Confirm identification and local rules.
- Use only a method permitted locally; the methods section distinguishes documented practice from unavailable advice.
- Release any protected, uncertain or unwanted catch promptly using appropriate handling.
Typical size
FAO common size: to 150 cm fork length. Not an island-specific catch average.
Maximum size
FAO account maximum: 195 cm fork length. Historical reference value, not a current angling record.
Edibility
Edibility is not established in the catalog; see the table-quality section.
Cleaning
No food recommendation is provided: the catalog has not verified human food use for this species.
Cooking suggestions
No food recommendation is provided: the catalog has not verified human food use for this species.
Safety warnings
FDA/EPA places yellowfin tuna in its Good Choices category with frequency guidance for pregnancy, breastfeeding and children. Consult that guidance; this is not an unlimited-consumption claim.
Regulations
Verify the rules for the actual fishing area before targeting or retaining this species. Unknown means pending verification, not unrestricted harvest. Area-specific classifications and sources appear below.
Conservation
Documented occurrence is not a population assessment. Avoid habitat damage and follow the local status below; protected occurrences are encounters, not harvest targets.
Physical appearance
Metallic blue back, silver belly and bright yellow fins and finlets with dark finlet margins.
Diet
A wide range of fish, crustaceans and cephalopods.
Behavior
Information unavailable in the species sources reviewed; no species-specific recommendation is inferred.
Fishing depth
Information unavailable in the species sources reviewed; no species-specific recommendation is inferred.
Fishing environments
Oceanic water above and below the thermocline. This is species-level habitat context, not proof for every linked area.
Table quality
No food recommendation is provided: the catalog has not verified human food use for this species.
Catch and release
For an ordinary small fish, minimize handling and air exposure, support its body and use a dehooker. Species-specific hazards take precedence.
