Reductive Evolution in Streptococcus Agalactiae, Emergence of a Host Adapted Lineage
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...

Evolutionary Perspective on Elovl5 fatty Acid Elongase: Pike, Salmon Comparison
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...

Oyster Culture In Recirculating Systems
David D. Kuhn et al Viginia Tech, have evaluated oysters cultured in a recirculating aquaculture system with zero water exchange for several months. Survival rates exceeded 99 per cent, and the oysters had growth comparable to or higher than oysters of...

Natural Products Effective Against Shrimp Disease, Suitable as Antibiotic Replacement
Research by Nelson Peña Navarro of the University of Costa Rica (UCR), has showed that some natural products can be substitutes for antibiotics in disease control of farmed shrimp. These natural alternatives can also increase production and maximise...

New Diagnosis Tool to Improve Conservation of Freshwater Fish
A scientific team of the University of Barcelona have applied a new diagnostic tool to evaluate the health status of Iberian native fish species and the ecological status of aquatic ecosystems. The new non-lethal diagnostic tool, based on the analysis...

More Rapid, Severe Disease Outbreaks for Aquaculture at the Tropics: Implications for Food Security
Aquaculture is replacing capture fisheries in supplying the world with dietary protein. Although disease is a major threat to aquaculture production, the underlying global epidemiological patterns are unknown. Tommy Leung, University of New England, and...

Alternative Perspectives on the Sustainability of Alaska’s Commercial Fisheries
Many believe commercial fisheries in Alaska, USA, are sustainability success stories, but ongoing socioeconomic problems across the state raise questions about how this sustainability is being defined and evaluated. Sustainable management of marine fisheries...

Broodstock Nutrition Management Enhances Reproduction, Profits
Proper management of broodstock nutrition encompasses providing the right amounts of the proper specialised nutrients during the right developmental stages, writes Scott Snyder, Animal Nutritionist, and Thomas R. Zeigler, Senior Technical Advisor, Zeigler...

Dietary Organic Acids Improve Gut Health, Disease Resistance In Olive Flounders
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,...

Some Alaskan Trout Use Flexible Guts for the Ultimate Binge Diet
Imagine having a daylong Thanksgiving feast every day for a month, then, only pauper’s rations the rest of the year. University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaska’s Chignik Lake...

Australian Fisheries Outlook to 2017-18 - March Quarter 2013
The gross value of Australia’s fisheries production is forecast to rise by one per cent to $2.4billion in 2012–13. The real value of Australian fisheries production declined significantly over the past decade, attributable to a decrease in the value...

Risk Management in Fish: How Cichlids Prevent Young from Being Eaten
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 Darwin’s theory of evolution, which suggests that animals...
