A molecular approach to the identification of larval billfishes
Outside of directed tournaments, Atlantic billfishes
are generally not the only targets in charter and recreational troll fishery of North Carolina.
Use of rostral characters for identifying adult billfishes
(Teleostei: Perciformes: Istiophoridae and Xiphiidae).
The istiophorid billfishes
are large, highly migratory predators, whose range and movements encompass vast geographical areas.
in the Atlantic Ocean experience considerable fishing pressure and most stocks are overfished.
Effort in the JLL is given as total number of longline hooks deployed and catch as numbers of boated and discarded tunas (several species), swordfish, and istiophorid billfishes
pelagic longline vessels and sales of Atlantic billfishes
have been prohibited since 1988.

Overview of fisheries for the billfishes
Abstract--The identification of larval istiophorid billfishes
from the western North Atlantic Ocean has long been problematic.
This is particularly relevant to highly mobile species, such as billfishes
, that can cover large distances in a short time (Prince and Brown, 1991).
recreational anglers include a minimum size of 66 inches lower jaw fork length (NMFS, 1999) and mandatory reporting of landed billfishes
The Fishery Management Plan for the Atlantic Billfishes
(FMP) was approved in September 1988 by the Secretary of Commerce, according to Joseph W.
However, evolving PSAT technology presents the opportunity for additional work describing the interactions between pelagic longline gear and catch species, such as the billfishes
