Pelagic fish species
Functional group 6: Swordfish
A single-species group, the swordfish (Xiphias gladius) is an highly migratory species with the stock range covering the entire north Atlantic and adjoining waters.
Functional group 7: Other billfish
With the exception of black marlin, all the species in this group are highly migratory with stock areas covering half or more of the Atlantic Ocean and adjoining waters.
|Atlantic blue marlin||Makaira nigricans|
|Atlantic white marlin||Tetrapturus albidus|
|Atlantic sailfish||Istiophorus platypterus|
|Longbill spearfish||Tetrapturus pfluegeri|
|Black marlin (see note)
Note: Black marlin are only known as strays into the Atlantic however they were included in the group for purposes of estimating diet composition of billfish overall.
Functional groups 8-11: Highly migratory tunas
These four functional groups each consist of one species of tuna. All are highly migratory with stock areas covering half or more of the Atlantic Ocean and adjoining waters.
Regional large pelagic fish
The regional large pelagic functional groups are all ones for which the stock area is believed to be relatively localized i.e. limited to the Lesser Antilles or at most the Wider Caribbean.
Functional group 12: Blackfin tuna
The single species group blackfin tuna (Thunnus atlanticus) is a small tuna prevalent in the southern parts of the LAPE area.
Functional group 13: Other offshore predators
This group includes several species of small tunas as well as pelagic triggerfish.
|Atlantic bonito||Sarda sarda|
|Bullet tunas||Auxis spp.|
|Little tunny||Euthynnus alletteratus|
|Spotted oceanic triggerfish||Canthidermis maculata|
|Ocean triggerfish||Canthidermis sufflamen|
Functional group 17: Pelagic sharks
A large number of pelagic shark species are known to occur in the LAPE area however there are few fisheries or other sources of detailed information. The following species are examples for which fishery and/or diet data were available.

The first trait we notice about Kryptopterus bicirrhis is of course its transparency hence the common name of 'glass' or 'ghost' catfish. The body is virtually transparent with scattered patches of pigment on the head and underbelly. We can see the swim bladder inside the body cavity adjacent to the pectoral fins and other internal structures, such as the vertabral column, can be seen.
In its native waters of southeast Asia you would think that such a soft bodied fish would stand out and prove an easy meal for predators, but to the contrary the glass cat can prove itself to do a disappearing act in the more murky river waters of its habitat

“This allows the predator fish to feed heavily on the forage fish species. Consequently, the predator fish species are fatter and healthier during the next years spawning season,” she explained.
