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…

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.

Studies conducted with gilthead sea bream (Sparus aurata L.) have determined the maximum dietary replacement of fish meal and oil without compromising growth or product quality.

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…

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…

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…

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…

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…
