Short-term movements and habitat preferences of sailfish, Istiophorus platypterus (Istiophoridae), along the southeast coast of Brazil

Neotropical Ichthyology
Pop-up satellite archival tags (PSATs) were deployed on four sailfish, Istiophorus platypterus, in the coastal waters of Rio de Janeiro State in southeast Brazil during January and February of 2009 (sailfish I and II) and between November 2010 and ...

Environmental and spatial effects on the size distribution of sailfish in the Atlantic ocean

Ciencias Marinas, 2010
Generalized regression analysis and spatial prediction (GRASP) was applied to size data for sailfish (Istiophorus platypterus) to better describe its preferential habitats in relation to juveniles and adults, based on environmental and spatial factors ...

Lacunae rostralis: A new structure on the rostrum of sailfish Istiophorus platypterus

Journal of Fish Biology, 2022
AbstractRecent comparative studies of billfishes (Istiophoridae and Xiphiidae) have provided evidence of differences in the form and function of the rostra (bill) among species. Here, we report the discovery of a new structure, lacuna rostralis, on the rostra of sailfish Istiophorus platypterus, which is absent on the rostra of swordfish Xiphias ...

Assessing Atlantic sailfish catch rates based on Brazilian sport fishing tournaments (1996-2014)

Boletim do Instituto de Pesca, 2016
In the present study, a generalized linear model (GLM), assuming a Tweedie distribution and log as link function, was used to generate a standardized catch per unit effort (CPUE) series for the sailfish caught by sport fishing boats based in São Paulo ...

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 ...

Killer Whales (Orcinus orca) in the Indo‐Pacific: A Review of Their Distribution, Population Structure, and Ecology

Mammal Review, Volume 56, Issue 3, September 2026.
This review synthesises knowledge on killer whales across the Indo‐Pacific through the integration of published studies and collaboration. It shows that variation in killer whale occurrence, diet, and fisheries interactions is shaped by environmental heterogeneity and uneven research effort and highlights knowledge gaps with implications for ...
