The aim of the present study was to evaluate the effect of feeding four levels of tuna oil on performance and fatty acid (FA) profiles of broiler chicken meat. 240 Ross broiler chickens were randomly assigned to 20 pens and divided into four treatments: 0%, 0.75%, 1%, and 1.25% of tuna oil. At 49 days, breast and legs-thighs muscles were processed for FA analysis. Concentrations of FA in legs a...

Fisheries are of crucial importance to many Pacific Island countries and for several, one of the largest earners of foreign exchange. The most significant fish and fishery products exported from the region are tuna and tuna products, i.e. sashimi, canned tuna and dried tuna. With the introduction of US Seafood HACCP Rule 1995 there is a strong incentive for countries that export seafood product...

Tuna fisheries catch over three million tonnes of skipjack tuna (Katsuwonus pelamis) each year, the majority of which come from purse-seine vessels targeting fish associated with man-made fish aggregating devices (FADs). A significant challenge for fisheries management is to maximize the efficiency of skipjack tuna catches whilst minimizing the bycatch of small and immature bigeye (Thunnus obes...

restaurants. Japan consumes about 80 per cent of Pacific and Atlantic bluefin tuna. The country has been accused of stifling efforts to enhance protection of the tuna stocks. In negotiations last year, a bid by Monaco, backed by several other European countries, to introduce a ban on commercial fishing of Atlantic bluefin tuna failed because of perceived support from several smaller nations for...

UNLABELLED The software package TUNA (Testing UNtyped Alleles) implements a fast and efficient algorithm for testing association of genotyped and ungenotyped variants in genome-wide case-control studies. TUNA uses Linkage Disequilibrium (LD) information from existing comprehensive variation datasets such as HapMap to construct databases of frequency predictors using linear combination of haplot...

Meatballs are a type of food that is very well known and liked by the wider community ranging from children to adults. made skipjack tuna (Katsuwonus pelamis) have not been found in market, even though Maluku one potential commodities. Skipjack contains 19.6 g protein beneficial for growth children. The use local process it into nutritious product important, meaning reducing dependence on impor...

This study presents a methodology for the automated analysis of commercial medium-range sonar signals for detecting presence/absence of bluefin tuna (Tunnus thynnus) in the Bay of Biscay. The approach uses image processing techniques to analyze sonar screenshots. For each sonar image we extracted measurable regions and analyzed their characteristics. Scientific data was used to classify each re...

Bigeye tuna (Thunnus obesus) have distinctive depth distributions and vertical movement patterns. They remain in the uniformed temperature surface layer at night and can descend to greater than 500 m depth at dawn. They thus mirror the vertical migrations of the small nektonic organisms of the deep sound scattering layer and extensively exploit these as a food resource. At their maximum depths,...

We used acoustic telemetry to examine the small-scale movement patterns of yellow®n tuna (Thunnus albacares) in the California Bight at the northern extent of their range. Oceanographic pro®les of temperature, oxygen, currents and ̄uorometry were used to determine the relationship between movements and environmental features. Three yellow®n tuna (8 to 16 kg) were tracked for 2 to 3 d. All three...

Specialisations in excitation-contraction coupling may have played an important role in the evolution of endothermy and high cardiac performance in scombrid fishes. We examined aspects of Ca(2+) handling in cardiomyocytes from Pacific bonito (Sarda chiliensis), Pacific mackerel (Scomber japonicus), yellowfin tuna (Thunnus albacares) and Pacific bluefin tuna (Thunnus orientalis). The whole-cell ...
