Tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues. However, pole-and-line tuna fisheries are widely believed to have low bycatch rates, although these have rarely been quantified. The Maldives has an important pole-and-line fishery, targeting skipjack tuna (Katsuwonus pelamis). In the Maldives, 106 pole-and-line tuna fishing days were observed ...

This study was to utilize the waste from canned tuna processing (tuna precooking juice) for producing dried tuna flavor powder. Tuna precooking juice was centrifuged and concentrated to 15% total soluble solid (TSS). Maltodextrin (DE 9) was added to increase the TSS of tuna precooking concentrate to 20, 22, 24 and 26%, then dried by spray dryer at 180oC inlet air temperature. The compositions a...

Tuna are large pelagic fish whose populations are close to panmixia. In addition, they are threatened species, so it is important for the maintenance and monitoring of genetic diversity that genetic information at a genome level be obtained. Here we report the draft assembly of the southern bluefin tuna genome and the collection of genome-wide sequence data for five other tuna species. We sampl...

Total mercury was measured in 156 composites prepared from 936 samples of canned tuna sold in Canada in 2006. Each composite comprised a single brand. Yellowfin tuna contained the lowest concentrations, averaging 0.066 mg/kg. Skipjack tuna contained slightly higher concentrations, averaging 0.132 mg/kg. The highest average concentration was found in the Albacore tuna: mean 0.325 mg/kg, range 0....

objective: the orange-red spectrum of  the skin of  electric yellow (labidochromis caeruleus) is  one  of  the  idealistic and  necessary  schemas sought  by  aquarists  and commercial producers. in this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total l...

Schistura sirindhornae, a new species of nemacheilid, is described from the Nan River basin in northern Thailand. It is distinguished from all other species of Schistura in having overlapping scales on the entire body similar to scales of balitorids, transparent scales on the belly and thorax, a lateral-line canal that is similar to that of most cyprinids and balitorids in being present across ...

Species of the anglerfish genus Chaunax Lowe, 1846 from the New Zealand region are taxonomically reviewed with six species recognized and described: Chaunax penicillatus McCulloch; C. nudiventer Ho & Shao, a new record for New Zealand; and four species new to science. Chaunax flavomaculatus sp. nov. distinguished by having its skin covered with a mix of numerous bifurcated and simple spinules, ...

BACKGROUND Benign prostatic hyperplasia (BPH) constitutes a major clinical problem. Minimally invasive therapies for the treatment of symptomatic BPH include Transurethral Needle Ablation (TUNA), but it is unclear what impact this technique has on the disease and its role among other currently available therapeutic options. The objective of this study is to ascertain the efficacy and safety of ...

Tuna are highly priced fishes that are often used in processed products. For effective fishery management and protection of consumers’ rights, it is important to develop a molecular method to identify the specie...

To analyze the potential trophic interactions among tuna larvae and other fish species, we studied the larval fish assemblages inhabiting the surface mixed layer around the Balearic Islands using data from two surveys carried out in summer 2006 and 2008. Despite the high diversity, Thunnus alalunga, Auxis rochei, Cyclothone pygmaea and Ceratoscopelus maderensis clearly dominated the catch in bo...
