624 results about "Silver carp" patented technology

The silver carp (Hypophthalmichthys molitrix) is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia. Although a threatened species in its natural habitat, it has long been cultivated in China. By weight more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species.

Planting and breeding integrated ecological breeding method for large fishpond

Technology of extracting and refining fish oil from internal organs of silver carps

The invention relates to a technology of extracting and refining fish oil from internal organs of silver carps, and belongs to the technical field of recycling freshwater fish scraps. According to the technology of extracting and refining the fish oil from the internal organs of the silver carps, firstly, the internal organs of the fresh silver carps are ground into thick liquid after fish gall bladders are removed from the internal organs of the fresh silver carps manually, alkaline protease is utilized to process the thick liquid to extract crude oil, then the crude oil is degummed with phosphoric acid, deacidified with sodium hydroxide, decolored with activated carbon and deodorized in vacuum mode, and then high-quality edible fish oil is extracted. Therefore, not only is waste of resources reduced, but also economic benefits of a freshwater fish processing enterprise are increased. According to the technology of extracting and refining the fish oil from the internal organs of the silver carps, due to the fact that water is not utilized to wash the internal organs of the fresh silver carps, the yield of fish oil can be increased by 5%, and the quality of the fish oil is higher. After the fish oil is refined from the internal organs of the silver carps, remaining material can be processed into high-calcium and high-protein fish meal, and the effect that the freshwater fish scraps are turned from waste into treasure is truly achieved. The problems that existing freshwater fish scraps are mostly used to feed fish in fish ponds in fresh mode or in dried mode, or are even discharged as the waste, and therefore the environment is polluted, and the resources are wasted are solved. The technology of extracting and refining the fish oil from the internal organs of the silver carps has very good social benefits and economic benefits.

Germ cell marker using fish vasa gene

ActiveUS8222385B2Easily successEasily failureTissue cultureImmunoglobulinsOogoniumChub mackerel
In order to examine whether or not a germ cell derived from a donor fish, which has been transplanted into a recipient fish of a different species by a surrogate fish technique, grows or matures in the gonad of the recipient fish, it is necessary to use, as an indicator, a trait that is specifically expressed in the germ cell and can be used to distinguish the recipient fish from the donor fish. Vasa gene, which is a germ cell-specific gene, is specific to a primordial germ cell and a spermatogonium / an oogonium, and it is not expressed in a somatic cell. In the present invention, the Vasa gene sequences of a tuna, a chub mackerel, a spotted mackerel, an eastern little tuna, and a drumfish are determined, and the expression of such gene is used as a marker for a germ cell. In addition, according to the present invention, it is possible to specifically detect only a tuna Vasa gene in Vasa gene sequences that are highly conserved in fishes, without sequencing. Thus, a tuna-derived germ cell can be reliably and simply identified in the gonad of the recipient fish. As a result, the growth or breeding of tuna can be carried out with good efficiency. Moreover, utilizing the aforementioned findings, even in a case in which not only a tuna but also another Perciformes fish is used as a donor, a germ cell derived from the donor fish can be efficiently detected from the gonad of a recipient fish of a different species.
