  • Use of arachidonic acid for enhanced culturing of fish larvae and broodstock
    Patent number: 7067145
    Abstract: A method of enhancing a culturing characteristic of fish larvae, including administering to said larvae in a nutritional diet essential fatty acids including DHA and AA in a ratio effective to enhance the culturing characteristic of such fish larvae relative to a corresponding nutritional diet lacking DHA and AA. The culturing characteristic may be at least one of stress resistance, immunoresistance, hatching rate, and growth rate. In a preferred aspect, the DHA and AA together comprise from about 10 to about 30% of total fatty acids in enrichment lipids, and the dietary ratio of DHA: AA is less than 10.
    Type: Grant
    Filed: September 7, 2001
    Date of Patent: June 27, 2006
    Assignee: University of Maryland Biotechnology Institute
    Inventors: Allen R. Place, Moti Harel

  • Methods for the enrichment of live feed with nutrients essential for fish larvae
    Patent number: 6261590
    Abstract: A method of enriching fish food and live larval fish prey, especially Artemia nauplii and rotifers, with essentially highly unsaturated fatty acids, vitamins, amino acids, carotenoids and pigments. The live prey are allowed to ingest/adsorb dry soap powders of highly unsaturated fatty acids obtained from the waste stream of marine algae oil extraction. The live prey can be highly enriched in docosahexaenoic acid obtaining ratios of docosahexaenoic acid to eicosapentaenoic acid greater than about 2.0 to 1.0.
