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....

Accumulation of urocanic acid (UCA) in stored fish has been attributed to both endogenous and exogenous histidine ammonia lyase (HAL) activity. The level HAL Indian mackerel, tuna, sardine were monitored at different temperatures. It was also evaluated during storage eviscerated whole under vacuum packaging. UCA production storage. highest the lowest activity fresh observed mackerel tuna (26.32...

This paper describes an Automated Visual Inspection System SIVATUN" for quality control of Tuna Meat which automate manual inspection operation. Depending on whether tuna are reared in cages or in the open sea and depending on the method of capture (electroslaughtering, shooting, etc.), differences are observed and changes take place in the organic nature of Blue Fin Tuna (Thunnus Thynnus) meat...

Tuna (Thunnus thynnus) is a food that often consumed raw to support diet activities, so it has the potential be contaminated with Salmonella typhi bacteria. Fish can by bacteria due their high water and protein content. Indonesia world's main tuna producer. detection in fresh must negative for microbial contamination order meet safety requirements. Microbial testing drawbacks, such as long dela...

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...

Consuming small-sized fish species whole, and bones of large fish could contribute significantly to reducing the level of micronutrient and protein malnutrition. These fish products are more affordable and could therefore meet the needs of poor, vulnerable groups, particularly in rural and urban areas where limited economic resources prevent dietary diversity. The objectives of the study were t...
