New research shows that mice eating sugar together with fat become significantly fatter than mice that eat protein with fat. The results will be used to examine what happens when diets with marine omega-3 fatty acids are combined with sugar. New research indicates that whether fat in diets is combined with sugar or protein play a role with respect to maintaining body weight. In an experiment carried out at the National Institute of Nutrition and Seafood Research (NIFES) one group of mice...

Aquaculture feeds characteristically contain a higher percent of protein than feeds used in agriculture for poultry, swine, and beef. A typical commercial production diet formulated for tilapia or catfish contains approximately 32-40% protein, while one formulated for trout or salmon contains as much as 44-50% protein, on a dry weight basis. A commercial grower diet formulated for most terrestrial animals rarely exceeds 20% in total protein, and even for carnivorous species such as cats, the...

Scientists at Nofima have developed a salmon feed that strengthens the immune defence among salmon so the survival rate after a natural outbreak of the IPN virus increases dramatically. Professor Kjell-Arne Rorvik at Nofima Marine (formerly Akvaforsk) believes this is an example of the fish feed of the future. "The best way of significantly improving fish feed involves finding and utilising components that collaborate with the fish's biology so that the energy in the feed is...

Channel catfish ( Ictalurus punctatus ) raised in ponds are typically fed daily to apparent satiation to obtain maximum growth. However, under certain economic circumstances, catfish producers may feed less than daily to reduce feed cost and minimize economic losses. Robinson and Rushing (1994) compared different feeding strategies (once daily, every other day [EOD], once every third day [ETD] to satiation, and once daily to half satiation) for pond-raised channel catfish. They reported...

Improved feed management strategy, including the use of optimal combinations of fertilisers, feed ingredients and manufactured feeds, could lower costs and optimise production of aquatic species, says the Food and Agriculture Organisation of the United Nations (FAO). This, says the FAO, calls for an increased understanding of the economics and cost-benefit analysis of these practices. The FAO Fisheries and Aquaculture Department Technical Paper, 'Economics of...

Kiotech International plc is pleased to announce the successful completion of a seven-month trial of its Aquatice® attractant to enhance the rate of growth and feed conversion in catfish (Clarias sp.). The eight-pond trial was conducted in Southern Thailand. This is one of a number of Aquatice® trials being carried out on a range of fish species in South East Asia and the first on catfish. The Aquatice® treated ponds delivered double the number of large catfish, which command a premium price in...

Fish meal used in fish feed contains high levels of taurine, which is not the case for plant proteins. What are the consequences when the levels of plant protein in the diet are high? New research at NIFES shows that the farmed salmon`s requirement for taurine is met when the feed contains sufficient amount of the precursor amino acids. Fish meal contains high levels of the sulphuric amino acid taurine. Today’s grow-out feed for Atlantic salmon contains up to 50 % plant protein, due to...

Prosol, an Italian private company very active in the production of natural Nucleotides for food dietary, announces the creation of a new range of products for aquaculture based on Nucleotides. Based on a well known independent scientific literature, these products provide a certain source of Free 5’ Nucleotides(F5N). Indeed has been proven that nucleotides only in free form enhance the immune system response to stress factors. NUCLEO 5 PRIME™ is the newborn in Prosol range,...

New research from Norway shows the levels of DHA that ensure better growth, survival and normal pigmentation in Atlantic halibut larvae. The bottleneck in halibut farming is related to insufficient supply of important nutrients. Two feeding trials at NIFES, in collaboration with the Norwegian Institute of Marine Research, suggest for the first time minimum levels of the marine fatty acid DHA needed for good survival and normal pigmentation. In a feeding trial, a group of Atlantic...

It is common knowledge among skin experts that glowing skin comes from healthy habits. The Central Institute of Freshwater Aquaculture (Cifa) has now reinforced the belief, only in respect to ornamental fishes. The Cifa scientists have found an organic feed that “enhances” the colour and brightness of ornamental fishes — by including maize, drumstick leaves, marigold petals and rose petals to the fish feed. And more than the fishes, it is the hobbyists and breeders who are...

According to research from the Cheju National University, on a paper presented at Aquaculture America 2008, tons of citrus peel by-products from the citrus juice processing in Korea, plus dead fish from commercial-scale aquaculture farms, can be turned into a highly valuable aquafeed, easing at the same time the enormous economical loss for both industries, and considerable environment damage.

The lowly, less utilized Balunggay (scientific name: Moringa oleifera , Malunggay in Tagalog) is a good source of protein for Tilapia feeds. Wally Afuang, Executive Director of the Northern Negros Aquatic Resources Management Council (NNARMAC), said the Balunggay tree holds a considerable potential for becoming an ingredient for animal and fish feeds because of its high nutritional quality that is comparable to other feed protein sources. Afuang...
