The identification of the genetic basis domestication in fish species is timely importance for aquaculture industry order to increase productivity, quality, and welfare farmed fish. goal this study investigate largely unknown aquaculture-induced evolution gilthead seabream, which one most important Mediterranean region. We used a panel 1159 genome-wide SNPs, genotyped 956 from 23 wild populatio...

Introduction Experimental trials were recently conducted at the InterAmerican Tropical Tuna Commission (IATTC) Achotines Laboratory in Panama to investigate the potential impacts of ocean acidification on the early life history stages of Thunnus albacares (yellowfin tuna). With analyses of data collected from the trials expected to be completed soon, the following article describes the growing ...

The Gram-negative bacteria Aeromonas hydrophila is a heterogeneous organism that causes the disease known as motile aeromonad septicaemia, which is responsible for serious economic loss in seabream culture due to bacterial infections. However, the immune mechanisms involved in this disease in fish are still poorly understood. For the purpose of this study, gilthead seabream (Sparus aurata L.) s...

We investigated the associative behavior of skipjack (Katsuwonus pelamis), yellowfin (Thunnus albacares), and bigeye (T. obsesus) tuna within multi-species aggregations associated with drifting fish aggregating devices (dFADs) in two different regions western Indian Ocean: Mozambique Channel Seychelles, using acoustic telemetry. documented residence absence times tunas at temporal scales (coars...

Abstract Predation is important in maintaining the community structure, functioning and ecological resilience of estuarine seascapes. Understanding how predator seascape context habitat condition combine to influence predation vital managing ecosystems. We measured relationships between species richness, abundance individual abundances as well condition, on relative probability mangrove forests...

Abstract The Sangihe Islands is located in the Republic of Indonesia Fisheries Management Area (WPPNRI) 716, which has an area about 52.5 million hectares. potential productions for small and large pelagic fish WPP NRI 716 are 332,635 tons/year 181,491 tons/year, respectively, with utilization rates 0.48 0.63. dominant species caught were skipjack, mackerel, yellowfin tuna, anchovies. In order ...

Morphological characteristics such as meristic counts and body shape have long been used in stock identification. Fifty striped seabream, Lithognathus mormyrus, individuals were sampled from the south Black Sea between January 2020 November 2020. Morphometric characteristics given percentage of total length (TL%). Species identification differences sexes seabream analyzed by different statisti...

Urgent measures to save falling stocks of tuna in the world's second biggest tuna fishery — the eastern Pacific— have failed to be implemented, according to several environmental groups. Closure of the fishery, both by area and by time, was demanded by the groups to protect rapidly decreasing Pacific populations of yellowfin and bigeye tuna. But the annual meeting of the Inter American Tropical...
