Mating competition between farmed and wild cod Gadus morhua
Increasing numbers of hatchery-produced fish entering marine environments has caused concern over potential fitness depressions in wild populations, yet no study has addressed the likelihood of hybridisation between farmed and wild marine fish. Escape rates of Atlantic cod Gadus morhua L. from commercial net pens have been substantial and there is a risk of interbreeding between depleted local ...
متن کاملKinetics of heat denaturation of proteins from farmed Atlantic cod (Gadus morhua)
Protein denaturation is considered to be the main reason for both water loss and textural changes in fish during thermal processing. Denaturation of proteins in muscle of farmed Atlantic cod was studied by differential scanning calorimetry. The denaturation of the proteins was compared to cook loss and loss in water holding capacity and it was shown that the protein denaturation occurs in a low...
متن کاملIodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...
متن کاملFrancisella philomiragia subsp. noatunensis subsp. nov., isolated from farmed Atlantic cod (Gadus morhua L.).
Seven bacterial isolates from farmed Atlantic cod displaying chronic granulomatous disease were characterized by phenotypic and molecular taxonomic methods. The isolates were Gram-negative, facultatively intracellular, non-motile, strictly aerobic coccobacilli which produced H(2)S from cysteine-supplemented media and are therefore phenotypically consistent with members of the genus Francisella....
متن کاملAuthentication of Atlantic cod (Gadus morhua) using real time PCR.
This work describes the development of a real-time polymerase chain reaction (RT-PCR) system for the detection and identification of Atlantic cod (Gadus morhua). Among the advantages of this technique, it is worth highlighting that this is reliable in terms of specificity and sensitivity. The TaqMan real-time PCR is the simplest, fastest testing process and has the highest potential for automat...
