Juvenile production of Nile tilapia comprises a stage with high economic losses due to disease outbreaks, as stressful conditions caused by increased fish handling at this stage favouring opportunistic infections by several pathogens, write Santiago Benites de…

Good water quality on tilapia farms depends on a suitable environment to promote growth. Such an environment can be achieved by maintaining the correct balance between feed input and the assimilative capacity of the water. However, the more fish that are grown…

In recent years, piscine reovirus has emerged as a pathogen of interest to European salmon producers. The complete spectrum of effects that this virus has on infected fish is not yet fully understood, making it difficult to ascertain the full implications to t…

A new study from The University of Cambridge shows that cichlid fish reared in larger social groups from birth display a greater and more extensive range of social interactions.

Water quality is very important in fish farming as poor quality water can effect the health and growth of the fish. It is important that farmers pay attention to the water's chemical and physical factors.

Fish fed polystyrene nanoparticles are less active and show changes to theirbrains and metabolism, according to a study by Swedish and Danish researchers.The findings suggest that nanoparticles in the environment could have a majorimpact on fish and aquatic ec…

Fish species capable of warming their body core are able to swim two and a half times faster than those whose body temperature does not change, according to a study from the University of California, Santa Barbara and other institutions.

The stocking rate of channel catfish in aquaculture can affect production, but what effect does it have on the development of off-flavours in fish flesh? This study by Bartholomew Green and Kevin Schrader from the US Department of Agriculture aimed to answer t…

The benefits realised by recirculating aquaculture systems including enhanced fish growth, product quality and survival, as well as reduced treatment costs have made the recirculating aquaculture systems (RAS) approach an important production trend, write Stev…
