The immune response of Atlantic cod, Gadus morhua L
Interest in cod aquaculture has been growing over the last few decades, resulting in varied research on cod aimed at optimising conditions for both growth and survival. Cultural conditions may increase the danger of infections. Disease control by vaccination has proved successful in the farming of several fish species. However, cod do not respond well to vaccination. Recently it was shown that ...
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...
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 کاملDescription of Embryogenesis of Atlantic Cod Gadus Morhua
This paper presents a description of the embryonic development of Atlantic cod Gadus morhua. In addition, an equation describing the effect of temperature on developmental rate was developed. The whole period of embryogenesis was divided into 6 subperiods and 75 specific stages based on the distinctive characteristics. Temperature effects on the developmental rate of Atlantic cod embryos were s...
متن کاملExophiala angulospora causes systemic inflammation in atlantic cod Gadus morhua.
Species of Exophiala are opportunistic fungal pathogens that may infect a broad range of warm- and cold-blooded animals, including salmonids and Atlantic cod. In the present study, we observed abnormal swimming behaviour and skin pigmentation and increased mortality in cod kept in an indoor tank. Necropsy revealed foci of different sizes with a greyish to brownish colour in internal organs of d...
