Fermented asparagus-containing black sea bream feed and preparation method thereof

The invention relates to the field of fish feeds, in particular to a fermented asparagus-containing black sea bream feed and a preparation method thereof. The feed is prepared from a protein source raw material, a fat source raw material, a sugar source raw material and an auxiliary material, and further comprises 5 to 20 weight percent of fermented asparagus powder; the protein source raw material is prepared from fish meal, bean pulp and fermented asparagus; the fat source raw material is prepared from fish oil or soybean oil or a mixture of the fish oil and the soybean oil; the sugar source raw material is starch; the auxiliary material is prepared from one of or a mixture of several of mannan oligosaccharide, composite vitamins, a mixed mineral substance, microcrystalline cellulose, soybean lecithin powder, DL-methionine, monocalcium phosphate, choline chloride, ascorbic acid and sleeve-fish ointment. According to the fermented asparagus-containing black sea bream feed and the preparation method thereof, compared with non-fermented asparagus powder, the fermented asparagus powder added into the black sea bream feed has more ideal nutritional components. Compared with the existing black sea bream feed, the fermented asparagus-containing black sea bream feed disclosed by the invention has the advantages that the protein utilization rate, the fat utilization rate, the soluble polysaccharide utilization rate and the energy conversion rate of the fermented asparagus by black sea breams are higher.

Overwintering cultivation method of seawater fish black sea bream net cage

The invention belongs to seawater fish cultivation technique, and particularly relates to an overwintering cultivation method of a seawater fish black sea bream net cage. The method specifically comprises the following steps of A, selection of a sea area, that is to say, a seawater quality index conforms to an NY5052-2001 water quality standard of seaculture of pollution-free food, the salinity is 2-3%, the pH value is 7.8-8.6 and the dissolved oxygen is more than 5 mg / L; when the water temperature of the sea area rises to more than 15 DEG C in the following spring, a black sea bream cultivation net cage is slowly hauled back to an open sea area to cultivate; B, selection of the net cable and cultivation density, that is to say, the overwintering cultivation net cage selects a conventional small net cage or a deep water net cage, a plurality of net cages form a net row type structure and are arranged in parallel along the downstream direction; during overwintering cultivation, the cultivation density of the black sea bream net cage is 8-10 g / cm<3>; C, feed selection; D, a feeding method of a feed, that is to say, feeding is not carried out under the conditions of the water temperature in winter of lower than 10 DEG C and rainy days, feeding is carried out at sunny days at more than 10 DEG C, satiation feeding is carried out at 13:30 to 15:30 at one time, and the feeding rate is controlled within 1%-2%. According to the method, successful overwintering of cultivation of the black sea bream net cage is implemented through management of the cultivation method and feed improvement.

Molecular biology method of identifying black sea bream

The invention relates to a molecular biology method of identifying a black sea bream. The method mainly comprises the steps of designing a universal primer pair of perciformes fishes; conducting amplification sequence detection on deoxyribonucleic acid (DNA) samples of common valuable and rare perciformes fishes through the universal primer pair, selecting a particular DNA section of each kind of common valuable and rare perciformes fish according to sequence detection results, selecting a specific primer of the black sea bream from the DNA section, matching one primer in the universal primer pair with the specific primer to constitute a specific primer pair of the black sea bream, using the specific primer pair to conduct amplification on the samples of the common valuable and rare perciformes fishes, obtaining an identification standard electrophoretic band of the black sea bream according to an electrophoretic band of products, mixing the universal primer pair and the specific premier of the black sea bream so as to form a mixing premier, conducting amplification on DNA samples of fishes to be identified by adoption of the mixing premier, and comparing the electrophoretic band of the products and the identification standard electrophoretic band so as to obtain a species identification result.
