Maximum swimming speeds of sailfish and three other large marine predatory fish species based on muscle contraction time and stride length: a myth revisited [PDF]
Billfishes are considered to be among the fastest swimmers in the oceans. Previous studies have estimated maximum speed of sailfish and black marlin at around 35 m s−1 but theoretical work on cavitation predicts that such extreme speed is unlikely.

Considering that the quantitative and ecological studies related to parasites of scombrids are scarce in Brazil and that in Rio Grande do Norte (RN) there are no records, specially of Trematoda in Euthynnus alletteratus, this work reports the presence of the digenean Lobatozoum multisacculatum as well as their ecological parasitic indexes in this host ...

Quality Enhancement of Canned Little Tunny Fish (Euthynnus alletteratus) by Whitening Solutions, Pre-Cooking Time and Filling Medium [PDF]
The impact of three treatments as whitening (brine and/or H2O2); pre-cooking time (60 min, 70 min and 80 min) at 102 ± 1°C; and filling medium (brine, olive oil, sunflower oil and/or mixing) on quality of native little tunny (Euthynnus alletteratus) during canning were evaluated.

Massive consumption of gelatinous plankton by Mediterranean apex predators. [PDF]
Stable isotopes of carbon and nitrogen were used to test the hypothesis that stomach content analysis has systematically overlooked the consumption of gelatinous zooplankton by pelagic mesopredators and apex predators.

An unprecedented aggregation of whale sharks, Rhincodon typus, in Mexican coastal waters of the Caribbean Sea. [PDF]
Whale sharks, Rhincodon typus, are often perceived as solitary behemoths that live and feed in the open ocean. To the contrary, evidence is accumulating that they are gregarious and form seasonal aggregations in some coastal waters.

Diet and feeding ecology of the little tunny, Euthynnus alletteratus (Pisces: Scombridae) in the central Colombian Caribbean: changes in 18 years [PDF]
Trophic ecology and diet of the little tunny (Euthynnus alletteratus) in central Colombian Caribbean is described. The little tunny is a pelagic top predator but not a voracious fish (trophic level of 4.49, Q/B of 10.8). Its diet seems impoverished when compared with a study conducted in 1986 in the same general location and with studies in other ...
