The Pacific bonito, Sarda chiliensis, is anatomically intermediate between mackerel and tuna. The specialisations exhibited by tuna are present in the bonito, but to a lesser degree. Slow-twitch muscle strain and activity patterns were determined during steady swimming (tailbeat frequency 1.2-3.2 Hz) at four locations on the body of Sarda chiliensis using sonomicrometry and electromyography. Bo...

Fish skins constitute an important fraction of the enormous amount of wastes produced by the fish processing industry, part of which may be valorized through the extraction of gelatins. This research exploited the extraction and characterization of gelatins from the skin of three seawater fish species, namely yellowfin tuna (Thunnus albacares), blue shark (Prionace glauca), and greenland halibu...

The yellowfin tuna ( Thunnus albacares: YFT) is a widely distributed, migratory species that supports valuable commercial fisheries. Landings of YFT are seasonally and spatially variable, reflecting changes in their availability accessibility to different fleets metiers which, turn, has implications for sustainable management. Understanding the dynamics behaviour how it affected by biological e...

In April 1998, as part of a project to collect biopsy samples putative pygmy blue whales (Balaenoptera musculus brevicauda) in the waters around Republic Maldives, Indian Ocean, incidental sightings cetaceans encountered were recorded. Using modified line-transect methods and handheld binoculars, total 267 16 species dolphins recorded during 20 at-sea days northeastern atoll. Significant result...

Abstract Yellowfin tuna Thunnus albacares is one of the major species caught in Fisheries Management Area (FMA) 573 Indian Ocean. Its production contributed to 35.83% total 2013. The study was conducted assess population dynamics this FMA 573, based on length-frequency data collected 2013-2017, and analysed using FiSAT II software. results obtained show length-weight relationship W = 0.000052 F...
