Marlin

Marlins are both popular with sport fishermen and highly sought after in commercial fisheries, such as for sashimi and sushi. Although there is little data on their stockStock:
The fish of a particular species reproducing in the same area in the same period.  s, it is known that these species have become overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term.   in recent years. A recent assessment of Atlantic blue marlin indicates that this stock is still overfished and subject to overfishingOverfishing:
There is so much fish caught that the size of the stock has diminished so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term.  .

Marlin are widely caught as bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards).   in tuna and swordfish fisheries. Although these fishing methods are unlikely to affect habitat, the bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards).   of highly vulnerable species such as sharks, turtles and seabirds can be large.

Because marlins migrate far, international agreements for proper management are necessary. Recovery plans have been developed for certain species following scientific advice, but it is too early to tell if they will be effective. Catches are probably underestimated and observer coverage is low, so these fisheries are not well monitored. ManagementManagement:
