Variability in billfish vertical distribution and fishing interactions driven by environmental conditions in the Eastern Tropical Pacific Ocean

ICES Journal of Marine Science, 2023
Blue marlin (Makaira nigricans) and sailfish (Istiophorus platypterus) are ecologically important predators and valuable species throughout the world’s recreational, commercial, and subsistence fisheries.

Environmental controls of billfish species in the Indian Ocean and implications for their management and conservation

Diversity and Distributions: A journal of biological invasions and biodiversity, 2022
Billfish are epipelagic marine predators facing increasing pressures such as overfishing and rising global temperatures. Overfishing is a major concern, as they are caught by industrial longline fishers targeting tuna.

Colour vision in billfish

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Members of the billfish family are highly visual predatory teleosts inhabiting the open ocean. Little is known about their visual abilities in detail, but past studies have indicated that these fishes were likely to be monochromats. This study, however, presents evidence of two anatomically distinct cone types in billfish.

Chemical Forms of Mercury in Blue Marlin Billfish: Implications for Human Exposure

Environmental Science and Technology Letters, 2021
Although fish is an important source of nutrients, including some of the healthiest proteins, long-chain fatty acids, and essential selenium, species at the top of the food chain frequently contain...

Comparison of handline tuna catches in Indian Ocean and Banda Sea waters [PDF]

E3S Web of Conferences, 2021
There are two essential landing sites for handline tuna in Indonesia: Palabuhanratu (in the Indian Ocean) and Kendari (in the Banda Sea). This paper analyzes handline catches from the Indian Ocean and Banda Sea waters as the main fishing ground.

Distribution and habitat associations of billfish and swordfish larvae across mesoscale features in the Gulf of Mexico.

PLoS ONE, 2012
Ichthyoplankton surveys were conducted in surface waters of the northern Gulf of Mexico (NGoM) over a three-year period (2006-2008) to determine the relative value of this region as early life habitat of sailfish (Istiophorus platypterus), blue marlin ...

Incidental catch of billfish and other species by Venezuelan longline vessels in the Caribbean Sea and western Atlantic Ocean: Period 1986-2000

Ciencias Marinas, 2004
An analysis is made of the catch, effort and catch per unit effort (CPUE) of the incidental capture of billfish and other species by longline vessels in eastern Venezuela. The information was based on fishing logbooks from 1986 to 2000.

Modelling several morphometric relationships of swordfish (Xiphias gladius), black marlin (Makaira indica) and blue marlin (Makaira nigricans) caught from Indonesian longliners in the eastern Indian Ocean

Journal of Fisheries, 2016
This paper presents several equations for converting among measures of size (length and weight) for swordfish (Xiphias gladius), black marlin (Makaira indica) and blue marlin (Makaira nigricans) caught by Indonesian longliners in the Indian Ocean.
