    摘要: The invention discloses a method for controlling fish reproduction, the method comprises the following steps of: A, constructing a recombinant gene CMV-eGFP-SV40-CMV-Ga14-SV40 and establishing a GAL4 transgenic zebrafish line; B, constructing a recombinant gene CMV-RFP-SV40-UAS-antisense dnd and establishing a uas-antisensednd transgenic zebrafish line; and C, hybridizing by taking homozygous transgenic fish of the two lines as parents, and the hybrid generation fish was sterility. The method of the present invention takes a strategy that two fertilizable lines hybridized but hybrid generation is sterility, establishing a novel method with a universal meaning for controlling fish fertility; The method solves the contradiction of the reproductively sterility of fish and the hereditability of characters in a reproduction operation research and can be effectively applied to cultivation of new fish specie and population control.

    摘要: A test device for noninvasive testing of fish habitat selection and application thereof is described herein. The device includes a camera device, a water circulating system, a fish transporting barrel, and a test water tank. The fish transporting barrel is a water barrel with an openable bottom. The central area of the test water tank is arranged as a closed adaptation area, a water outlet is formed in the bottom of the adaptation area. Fish passages are formed in the adaptation area. Test areas with equal sizes are formed around the adaptation area through partition plates. A water inlet is formed in each test area. Water flow buffering plates are arranged corresponding to the water inlets. Fish passages are formed in the bottoms of the partition plates of the test areas. The water inlets of the test areas are connected to the water circulating system.

    摘要: A method for preparing a fish skin mucous gland bioreactor and its application, including: identifying genes specifically expressed in fish skin mucinous gland cells, promoters and secreted protein signal peptides, constructing transgenic expression vectors that can specifically express endogenous or heterologous biologically active substances in fish skin and mucous gland cells, developing stable genetic and transgenic fish that secrete bioactive substances into fish mucus, and using bioactive substances secreted by mucus glands for animal and plant growth, stress resistance and disease resistance, human health care and disease prevention, and commercial enzymes. The fish skin mucous gland bioreactor developed by the invention has the characteristics of easy breeding and expansion, more skin mucus secretion, convenient mucus collection, and easy purification of bioactive substances, and can realize the large-scale production of fish skin mucous gland bioreactor and efficient application.
