Fish: Feed & Nutrition

Feed and nutrition

Manual on the production and use of live food for aquaculture
The manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical properties and feeding methods.
Nutritional requirements of marine fish larvae and broodstock
As the  Mediterranean production of marine cultured  fish  increases,  the demand for good quality seed has been continuosly arising. To satisfy that increasing demand spawning quality and seed production success must be improved by controlling the nutritional quality of broodstock diets and first-feeding regimes
Proceedings of the 5th Fish and Shellfish Larviculture Symposium - larvi '09
Capitalising on the previous larvi symposia (in ’91, ’95, ’01, ‘05), the Aquaculture R&D Consortium of Ghent University, the Norwegian University of Science and Technology and the new COST action LARVANET” joined together to organize larvi’09, the 5th Fish and Shellfish Larviculture Symposium.
Effect of broodstock nutrition on reproductive performance of fish
 An improvement in broodstock nutrition and feeding has been shown to greatly improve not only egg and sperm quality but also seed production. Gonadal development and fecundity are affected by certain essential dietary nutrients, especially in continuous spawners with short vitellogenic period
Effect of iodine enrichment of Artemia sp. on their nutritional value for larval zebrafish (Danio rerio
Dietary iodine may play an important role in the nutritional health of freshwater fish larvae. Artemia, commonly used for the culture of larval zebrafish (Danio rerio), contain low concentrations of iodine when compared with wild-caught zooplankton. Iodine concentrations of Artemia can be increased using wax spray beads (WSB) containing potassiumiodide (KI; KIWSB); however, the availability of iodine in enriched Artemia for fish larvae is currently unknown
The problem of meeting dietary protein requirements in intensive aquaculture of marine fish larvae, with emphasis on Atlantic halibut (Hippoglossus hippoglossus L.)
Atlantic halibut are slow feeders and may thus suffer more from nutrient leaching than species eating more rapidly. Feed formulation techniques affect dietary protein leaching, and in this paper, different techniques and their impact on feed properties are described
Development of lipid microbeads for delivery of lipid and water-soluble materials to Artemia
Lipid spray beads (LSB) containing high concentrations of phospholipids were produced in order to improve their dispersion in both fresh and saltwater. The beads were developed to deliver both fat-soluble and water-soluble micronutrients to Artemia and other suspension feeders
Evaluation of wax spray beads for delivery of low-molecular weight, water-soluble nutrients & antibiotics to Artemia
In this study, wax spray beads (WSB) consisting of bees wax, with or without a 5% w/w extract of a synthetic marine phospholipid (mPHL), were evaluated for their potential for delivery of watersoluble micronutrients and the antibiotic oxytetracycline (OTC) to Artemia. The micronutrient mix consisted of amino acids, vitamins and trace minerals and was based on the nutritional composition of copepods.
Evaluation of changes in nutrient composition during production of cross-linked protein microencapsulated diets for marine fish larvae and suspension feeders
Cross-linked protein capsules as a vehicle for delivery of nutrients to marine fish larvae and marine suspension feeders were investigated. The effects of the production process on both qualitative and quantitative changes in protein, lipid and micronutrient concentrations were evaluated
Protein quality of larval feed with increased concentration of hydrolysed protein: effects of heat treatment and leaching
Four heat coagulated early weaning diets with increasing concentrations of pepsin hydrolysed protein, were investigated with regard to the change in protein quality during feed production and exposure to leaching
