The use of alternative lipids in tilapia feeds is becoming increasingly commonplace due to the rising cost of fish oil (FO). However, since this practice will reduce the content of heath beneficial long chain polyunsaturated fatty acids (LC-PUFA) in tilapia fi…
Recent advances in next-generation sequencing enabled an array of whole genome sequencing or re-sequencing projects in both model and non-model species. Such efforts have produced a wealth of genome resources. However, thorough genome analysis thereafter is es…
Jun Qiang, Chinese Academy of Fishery Sciences, and Hong Yanga look at the interacting effects of water temperature and dietary protein levels on hematological parameters in Nile tilapia juveniles and mortality under Streptococcus iniae infection.
The Asian region is a major supplier of fish products to the EU market. Over the period 2005-2010 in particular, the aquaculture sector in some Asian countries became an important producer as well as exporter of whitefish and shrimps.This article provides a su…
This article by Nathan K Lujan et al, Texas A&M University, looks at trophic diversity in the evolution and community assembly of South American loricariid catfishes.
Neil Wendover, MSD Animal Health, Singapore, uses field experiences from Asia to look at the implications of vaccine development for streptococcus in tilapia. Taken from the MSD Animal Health 'Bacterial Disease in Warmwater Fish: New Strategies for Sustainable…
Mark Gaikowski, Upper Midwest Environmental Sciences Center, US, determines the depletion of florfenicol (FFC) in water and florfenicol amine (FFA), a marker for FFC residue, from the fillet of market-weight tilapia in a recirculating aquaculture system (rAS) …
Grass carp (Ctenopharyngodon idella) is one of the most economically important freshwater fish, but its production is often affected by diseases that cause serious economic losses, report researchers from the Chinese Academy of Sciences.
Fish are constantly being moved and transported, having both an affect on their health and on their meat quality. Hans Van de Vis, from the Netherlands Institute for Marine Resources & Ecosystem Studies has looked at the stress response in farmed African c…
Rogrio Salvador, North Paran State University, looks at the impact of streptococcosis on tilapia in Brazil and efficacy of AquaVac Strep Sa for managing the disease under controlled conditions. Taken from the MSD Animal Health 'Bacterial Disease in Warmwater F…
Tilapia is losing ground in the US market whilst catfish supply is expected to increase during 2012 but with a stronger focus on quality and safety, according to the FAO Global Food Outloook.
