Both old and new information on the biology and ecology of Atlantic bluefin tuna have confronted scientists with research challenges: research needs to be connected to current stockassessment and management issues. We review recent studies on habitat, migrations and population structure, stressing the importance of electronic tagging results in the modification of our perception of bluefin tuna...

Mercury (Hg) was determined in Thunnus albacares canned in oil (from 7 to 10 samples per brand) and water (from 5 to 10 samples per brand) of five leading brands in Mexico in 2008. Potential health risk was estimated on the basis of Hg concentration and rate (1.43 kg year(-1)per capita) of tuna consumption in Mexico. Highest Hg concentrations were 0.51 ± 0.26 and 0.40 ± 0.24 μ gg(-1) dry weight...

on the basis of the some studies recently published on the concentration of potentially dangerous levels of mercury, a global pollutant and highly toxic element in sea fish and specially tuna fish, this work has been carried out to determine the concentration of mercury in canned tuna fish, that compose a large majority of the fish most people eat. for this reason, 30 cans, produced by differen...

As one of the most effective biosurfactants reported to date, lipopeptides exhibit attractive surface and biological activities have great potential serve as biocatalysts. Low yield, high cost production, purification hinder large-scale applications lipopeptides. Utilization waste materials low-cost substrates for growth biosurfactant producers has emerged a feasible solution economical product...

Directed fishing effort for Atlantic bluefin tuna in the Gulf of Mexico (GOM), their primary spawning grounds in the western Atlantic, has been prohibited since the 1980s due to a precipitous decline of the spawning stock biomass. However, pelagic longlines targeted at other species, primarily yellowfin tuna and swordfish, continue to catch Atlantic bluefin tuna in the GOM as bycatch. Spatial a...

This document forms part of the 2008 distribution of the TUNA Corpus, Version 1.0. This is the first public release of the complete TUNA Corpus of Referring Expressions. A subset of the corpus was used in the first Shared Task and Evaluation Challenge for NLG, the Attribute Selection for the Generation of Referring Expressions Challenge (ASGRE), co-located with the Workshop on Using Corpora in ...

7.1 Abstract Tuna oil-in-water emulsions containing droplets stabilized by lecithin-chitosan membranes were produced using a two-stage process. Corn syrup solids were added to the emulsions and then the emulsions were spray dried, which produced a powder consisting of smooth spheroid powder microcapsules (diameter = 5-30 μm) containing small tuna oil droplets (diameter <1 μm) embedded within a ...

Canned tuna (n = 240), salmon (n = 16), and mackerel (n = 16) were analyzed for mercury and fatty acids. Average mercury levels were 188, 45, and 55 ppb, respectively, and below the FDA Action Level of 1000 ppb. “Light tuna in water” contained lower mercury (x = 54 ppb) compared with “white/albacore tuna in water,” which contained higher eicosapentaenoic acid/docosahexaenoic acid (EPA/DHA) x = ...

Tuna processing by-product is estimated at more than 100,000 metric tonnes annually in Iran, which could be a potential source of edible protein in human food. Hence, recovering proteins from tuna by-products is a big achievement in the seafood industry. In this work tuna protein isolates (TPI) were extracted from dark/ red meat using the isoelectric solubilization/ precipitation method. Oxidat...

We report a case of a 17-year-old female adolescent who experienced an episode of exercise-induced anaphylactic reaction following ingestion of tuna sandwich (from soy containing canned tuna). Her medical history revealed that she had previously had one episode of urticaria after ingestion of sulfamethoxazole with trimethoprim and anaphylactic reaction after ingestion of sunflower nuts. Skin pr...
