From both nutritionist and aquaculturist points of view, the aim is to sustainably produce aquatic food with superior sensory properties and high cardioprotective properties. The reason is that although preventable, cardiovascular diseases (CVDs) remain the to…
F.F. Khalil, Ahmed Ismail Mehrim and Montaha E.M. Hassan, Al-Mansoura University, Egypt, have evaluated the effects of graded levels of a new commercial probiotic, Hydroyeast Aquaculture, on both sexes of adult Nile tilapia. The probiotic was found to be usefu…

Application of feeds in aquaculture can increase both production and profits considerably. Dr Seshaiah V. Pamulapati and Prakash Chandra Behera, PVS Group, India, discuss how trace minerals are having greater role in shrimp nutrition along with other minerals …
Research by Nelson Pea 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 profits and…
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 du…
This factsheet by the Southern Regional Aquaculture Center (SRAC) gives information on what feeds and feed ingredients should be used for channel catfish.
In a report from FAO entitled 'Edible insects: Future prospects for food and feed security', the potential is explored of using insects as a source of protein and other nutrients in dies for poultry and farmed fish.
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, Puky…
The rapid rise and growth of finfish and crustacean aquaculture has been due, in part, to the availability and on-farm provision of feed inputs within the major producing countries. If the aquaculture sector is to maintain its current average growth rate of 8 …
Commercial diets for channel catfish (Ictalurus punctatus) are typically composed of protein and energy sources of plant origin supplemented with lysine, vitamins, and minerals. A small amount of animal protein may be included. The predominant protein source i…
