The aim of this study was to evaluate whether NMR-based metabolomics is a suitable method to generate an integrated view on metabolic processes during food deprivation in salmonid fish. Juvenile rainbow trout (Oncorhynchus mykiss) weighing 43-115 g were either fed ad libitum or deprived of food for 28 days at 10°C to investigate catabolic effects on energy reserves and metabolite patterns. The ...

Out of the twenty-four samples of shrimp and fish muscle used for this study, twelve were collected near a large marine sewer for waste disposal, 3 km off the coast of Fortaleza (Brazil) and used for the isolation of E. coli. Other twelve were collected at the Mucuripe fresh fish market (Fortaleza, Brazil) and used for the isolation of Staphylococcus aureus. Ethanol, water and acetone-diluted e...

Disease are recognized as one of the major constraint to sustainable animal production which can cause significant economic loss especially in aquaculture. Various chemotherapeutic agents have been traditionally used in the treatment and prevention of diseases in farmed fish but they are not recommended since improper and continuous use of antibiotics may lead to potential development of antibi...

Several compounds from marine organisms have been studied for their potential use in aquaculture. Among the red algae, Asparagopsis taxiformis is considered one of the most promising species for the production of bioactive metabolites with numerous proposed applications. Here, the in vitro antibacterial activity, the easy handling and the absence of adverse effects on marine fish species are re...

The effect of pepsin digestion on the allergenicity of raw and thermally processed (boiled and fried) fish muscle extracts of two widely consumed fishes bhetki (Lates calcarifer) and mackerel (Rastrelliger kanagurta) was studied. Sere were collected from 110 patients who were hypersensitive to fish, as evidenced by their clinical history, symptoms and positive skin-prick test results. The vario...

The myofibrillar protein components of fish skeletal muscle have, so far, not been resolved in the same way as have those of mammalian muscle. The only fish myofibrillar proteins which appear to have been isolated and characterized at all fully are carp tropomyosin and carp nucleotropomyosin (Hamoir, 1951 a, b). Of the major components, it seems that the proteins hitherto called fish myosins mo...

Hydrolysates of cod viscera were tested as an alternative to commonly used complex nitrogen sources (peptones and/or extracts) for the type strains of the lactic acid bacteria Lactococcus lactis, Lactobacillus acidophilus, Lactobacillus helveticus, Lactobacillus casei, Lactobacillus sakei and Pediococcus pentosaceus. Comparative studies with MRS-like media containing different nitrogen sources ...

Background Fish is one of the main culprit foods in childhood allergy [prevalence below 5 years 30% and then 9.8%, Spain]. IgE-mediated fish allergy diagnosis (FAD) is based on specific IgE (sIgE) detection to fish whole extracts and parvalbumin, considered to be major allergen, despite oral challenge (OC) is still the gold standard. Parvalbumin is an important panallergen. Cod parvalbumin (Gad...
