摘要:
The present invention relates to a composition for controlling fish. In particular, the composition may be an incitant, functioning as either a fish attractant or a fish repellent. The composition may be prepared by extracting bacteria from a source fish, culturing the bacteria in an appropriate media, and subsequently combining the cultured bacteria with a substrate to form the composition.

摘要:
It is an object of the invention to increase the content of omega 3 fatty acids in carp meat to improve its nutritive properties and to achieve a better effect in prevention and treatment of many diseases of civilization. This effect is achieved by a feed comprising a mixture containing colza cake in the amount from 12 to 20% by weight, extruded linseed in the amount from 10 to 20% by weight, cereals in the amount from 56 to 72% by weight, soya grout in the amount from 5 to 10% by weight, limestone in the amount from 1 to 2% by weight, premix for carps in the amount up to 1% by weight and a stabilizing agent in the amount up to 0,5% by weight. The mixture can be added by linseed oil and/or rape oil and/or echium oil from the seeds of Echium plantagineum. The carp receives the above described supplementary feed in the ponds with a lower stocking density, where the half of the total increase of carp is formed by the natural food of plankton and benthos. The clean the meat and to improve the composition of fats the carp is maintained in post-harvest live-tanks. The reserve fat from the abdomen part characteristic for less valuable fats is removed when filleting.

摘要:
Aquaculture feed compositions having a ratio of concentration of omega-3 polyunsaturated fatty acids of eicosapentaenoic acid ["EPA"; cis -5, 8, 11, 14, 17-eicosapentaenoic acid; 20:5] to concentration of docosahexaenoic acid ["DHA"; cis -4, 7, 10, 13, 16, 19-docosahexaenoic acid; 22:6] greater than 2:1 based on the individual concentrations of EPA and DHA in the aquaculture feed composition, and having a biomass source of carotenoid(s), are disclosed. Furthermore, such aquaculture feed compositions may have a concentration of the sum of EPA and DHA that is at least about 0.8 %, measured as a weight percent of the aquaculture feed composition.
