Bycatch in drift gillnet fisheries: A sink for Indian Ocean cetaceans
Abstract In 1992, the UN banned the use of large‐scale pelagic driftnets on the high seas (UNGA Resolution 46/215). Three decades later, however, drift gillnets remain one of the primary fishing gears in the Indian Ocean, accounting for approximately 30% of tuna catches in this ocean.

The rostral micro‐tooth morphology of blue marlin, Makaira nigricans
Abstract Billfish rostra potentially have several functions; however, their role in feeding is unequivocal in some species. Recent work linked morphological variation in rostral micro‐teeth to differences in feeding behavior in two billfish species, the striped marlin (Kajikia audax) and the sailfish (Istiophorus platypterus).

Evidence from interpretable machine learning to inform spatial management of Palau's tuna fisheries
Abstract Static and dynamic area‐based management tools hold substantial potential to balance socioeconomic benefits derived from fisheries and costs from bycatch mortality of at‐risk species. Palau longline fisheries have high bycatch of at‐risk species including the olive ridley marine turtle and silky and blue sharks.

Abstract The sailfish (Istiophorus platypterus) is a mobile epipelagic billfish whose range extends across the world’s tropical and subtropical oceans. Once thought to be two allopatric species, respectively inhabiting the Indo-Pacific and Atlantic oceans, molecular analyses support a single species with global distribution.

Age and growth of sailfish (Istiophorus platypterus) in waters off eastern Taiwan
Age and growth of sailfish (Istiophorus platypterus) in waters off eastern Taiwan were examined from counts of growth rings on cross sections of the fourth spine of the first dorsal fin. Length and weight data and the dorsal fin spines were collected monthly at the fishing port of Shinkang (southeast of Taiwan) from July 1998 to August 1999.

Ichthyoplankton surveys were conducted in shelf and slopewaters of the northern Gulf of Mexico during the months of May–September in 2005 and 2006 to investigate the potential role of this region as spawning and nursery habitat of sailfish (Istiophorus platypterus).
