Equipped with the zebrafish genome, researchers have designed a method to assay the function of each and every gene and to explore the effects genetic variation has on zebrafish. So far the team has generated one or more mutations in almost 40 per cent of all …

Frank A. Chapman and Joel P. Van Eenennaam, in this University of Florida Publication, describe the standard method and tools for determining the sex of sturgeon by direct examination of the gonad using a minimally invasive surgical procedure.

Application of feeds in aquaculture can increase both production and profits considerably. Dr Seshaiah V. Pamulapati and Prakash Chandra Behera, PVS Group, India, discuss how trace minerals are having greater role in shrimp nutrition along with other minerals …

The ability to produce physiologically critical LC-PUFA from dietary fatty acids differs greatly among teleost species, and is dependent on the possession and expression of fatty acyl desaturase and elongase genes. Atlantic salmon, as a result of a recently du…

The Gram positive bacteria Streptococcus agalactiae (GBS) is a cause of severe epidemics in fish farms. To decipher the genetic basis for the emergence of these highly virulent GBS strains and of their adaptation to fish, Isabelle Rosinski-Chupin et al have an…

Imagine having a daylong Thanksgiving feast every day for a month, then, only paupers rations the rest of the year. University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaskas Chignik Lake watershed.

Excessive use of antibiotics can create resistance in aquatic pathogens and may result in residues that can harm the health of animals and humans. Organic acids provide a more sustainable alternative to routine use of antibiotics. A study by Gunhyun Park, Puky…

The gross value of Australias fisheries production is forecast to rise by one per cent to $2.4billion in 201213. The real value of Australian fisheries production declined significantly over the past decade, attributable to a decrease in the value of productio…

For a variety of reasons, many humans choose to adopt children. More surprisingly, adoption is fairly widespread in the animal kingdom, even though it would seem to counteract the basic premise of Darwins theory of evolution, which suggests that animals should…

Growth-enhancing transgenic biotechnologies have attracted considerable interest from the global aquaculture industry, particularly with regard to Atlantic salmon. However, similar to domesticated strains, concerns have been raised regarding the ecological and…

The aquaculture industry has grown dramatically, and plays an important role in the worlds food supply chain. Antimicrobial resistance in bacteria associated with food animals receives much attention, and drug use in aquaculture is also an important issue.

The rapid rise and growth of finfish and crustacean aquaculture has been due, in part, to the availability and on-farm provision of feed inputs within the major producing countries. If the aquaculture sector is to maintain its current average growth rate of 8 …

Commercial diets for channel catfish (Ictalurus punctatus) are typically composed of protein and energy sources of plant origin supplemented with lysine, vitamins, and minerals. A small amount of animal protein may be included. The predominant protein source i…
