BACKGROUND European sardines are an important fishing resource in the North Atlantic. Recognized for its great commercial and economic value in southern Europe, this resource currently has low stock indices. From this perspective, fishers' local ecological knowledge (LEK) is appreciated as an auxiliary tool in the management of sardines in this region. Our goal is to evaluate the LEK and attitu...

Abstract Two feeding trials were performed to evaluate the apparent digestibility coefficients (ADCs) of dry matter, protein, and amino acids three animal‐origin four plant‐origin ingredients in Totoaba macdonaldi . In first trial, evaluated using totoaba juveniles with an initial weight 529.7 ± 104.2 g, for second trial 745.9 210.6 g. Evaluated were: poultry by‐product meal, meat bone feather ...

The evaluation of seafood processing wastes is an important issue in terms both preventing environmental pollution and adding value to these economically. most practical method that can convert waste into a valuable feed source plant fertilizer make silage. In this study, the ripening times nutritional components fish silages prepared with direct addition lactic acid bacteria culture (Streptoco...

Regular consumption of seafood and, in particular, fish has been associated with important health benefits. A product that increasingly included the human nutrition is roe. Despite its nutritional value established (fatty acid profile and protein content), knowledge composition aqueous extracts still limited. This work describes bioactive compounds roe-derived three different marine species (sa...

Small pelagic fisheries show wide fluctuations, generally attributed to oceanographic anomalies. Most data on these fisheries come from landings, often reporting sustained catches-per-unit-effort (CPUEs) until a decline occurs. Fishery-independent data are important as management tools. In this study we show that the proportions of Pacific Sardine and Northern Anchovy in the diet of three seabi...

The choice of bait is one the fisheries tactics used to increase selectivity for particular target species. performance three types (mackerel, sardine, squid) was evaluated with a commercial vessel operating in Equatorial Atlantic Ocean using deep-set pelagic longline deployment method large yellowfin and bigeye tunas. effect different factors covariates on Capture per Effort Unit - CPUE throug...

approved: ___________________________________________________________________ Jae W. Park Myoglobin (Mb) was extracted from Pacific sardine and added to Pacific whiting surimi to measure its effects on protein gelation. The purity of Mb extract was determined by SDS-PAGE. Mb extracted using ethanol showed higher purity than Mb extract using ammonium sulfate. The addition of 0.2% Mb significantl...

A requisite for reliable food web models and ecosystem-based management in regions such as the California Current is the availability of diet information on key predators. In upwelling ecosystems, much of the lower trophic level energy may be transferred through a relatively small set of very abundant pelagic forage fish taxa, such as anchovies, sardines, smelts, and herring. In addition the pe...
