To maintain healthy ecosystem in aquaculture ponds and hatchery tanks bioremediation is the best biotechnology process, says Dr A. Venkateswara Rao, technical manager for Neospark Drugs and Chemicals. Pathogens as well as immunity suppressive agents can be eli…

Viral Encephalopathy and Retinopathy (VER) is a viral infectious disease affecting more than 50 marine fish species worldwide and it is considered one of the most important threats for mariculture in the Mediterranean, write Niccol Vendramin et al, University …

Although antibiotic growth promoters in the diets of fish may promote growth and improve feed conversion and survival rates, public concern over cross-resistance to humans led to a ban on the use of such substances in the EU. Research has thus turned to other …

The current trend towards increasing intensification and diversification of global aquaculture has led to its dramatic growth, thus making aquaculture an important food-producing sector that provides an essential source of aquatic protein for a growing human p…

Ten generations of domestication selection has caused farmed Atlantic salmon Salmo salar L. to deviate from wild salmon in a range of traits. In this study, the effects of environmental stress on mRNA expression levels of seven genes related to oxidative stres…

Due to poor growth, survival and abnormal pigmentation during larval development of halibut, this study aimed to evaluate the effect of photoperiod on growth, survival, food consumption and pigmentation in larvae reared under four light regimes.

Adaptation to different ecological environments is thought to drive ecological speciation. This phenomenon culminates in the radiations of cichlid fishes in the African Great Lakes.

Roy P. E. Yanong, University of Florida IFAS Extension, provides information on pentastomid infections in fish. Mr Yanong describes how the parasites affect fish and how infections can be treated.

The fibrous threads helping mussels stay anchored in spite of waves that sometimes pound the shore with a force equivalent to a jet liner flying at 600 miles per hour are more prone to snap when ocean temperatures climb higher than normal.

Fishing and the production of fish and fish products in Azerbaijan declined considerably in the early 1990s, with annual fish production falling from more than 20,000 tonnes in the early twentieth century to just 1,570 tonnes by the end of the century. Fish im…

Endogenous microbiota play essential roles in the hosts immune system, physiology, reproduction and nutrient metabolism. Research led by Matteo A. Avella, University of Marche, Ancona, Italy, treated zebrafish from birth to sexual maturation with Lactobacillus…

The Australian New South Wales government looks at the prospect of farming yabby. Yabby (Cherax destructor) is the best known of the hundred or so freshwater crayfish species found in Australia (not to be confused with the saltwater yabby, ghost shrimp or pink…

Oxidants are used in aquaculture as disinfectants or to enhance water quality. Hydrogen peroxide and sodium carbonate peroxyhydrate can be sources of dissolved oxygen in emergency situations where mechanical aeration is not possible, writes Claude E. Boyd, Aub…

Aquaculture has the potential to make a significant contribution to the increasing demand for aquatic food in most world regions; however, in order to achieve this goal, the sector will have to face significant challenges, including the production intensificat…

A new Seafish report shows that the food chain should be the first choice for discarded fish that could be landed under a future discard ban, but when that is not practicable then utilisation for fishmeal or fish oil reduction for animal feed, is currently the…

In a study, tilapia were fed fish oil or vegetable oil based diets for five months, then switched to a fish oil finishing diet for three months. Results showed growth and feeding efficiencies were not significantly compromised, writes Nicholas Romano et al, Un…

This paper by Anthony Charles of Saint Marys University, Canada, provides a preliminary exploration of current debates over the nature and interaction of rights within small-scale fisheries, and the connection of these rights with issues of global trade, subsi…

Processing of shrimp Artemia cysts is an important factor in price determination. Alireza Asem, Iran, therefore looks at new concepts for hatching quality and evaluation of Artemia.

In commercialization and high stocking density of culture practice, feeding has a significant contribution for fast growth and high yields. Aquafeed has many ingredients in highly balanced nutritious components for enhancing the digestive mechanisms in fish an…

Some countries in Southeast Asia are embarking on anchored Fish Aggregating Device (FAD) programmes to boost fish production and to increase food security. This advisory note from the FAO was written to provide guidance to fisheries managers and fishers on the…
