Second, the research direction

(1) Aquaculture: In view of the present situation that Tianjin is dry and rainless, which mainly belongs to saline-alkali water bodies, the research on the famous, special, excellent and new varieties breeding, fry breeding, intensive aquaculture proliferation, healthy aquaculture technology, and the establishment of ideal varieties and modes of protective fisheries has distinct characteristics and advantages, and some of them are at the leading level in China.

Facilities, intensification, large-scale farming and informatization have always been the research focus in this direction. The intensive culture technology of Trionyx sinensis has been studied successively, and the suitable range of a new hatching medium and ecological factors for Trionyx sinensis eggs has been determined. The ideal intensive culture mode and the suitable range of main ecological factors for Trionyx sinensis in different growth stages have been explored, achieving high yield and high efficiency, and winning the second prize of Tianjin Science and Technology Progress Award and two authorized patents. "Ecological fish culture technology combining fish and poultry", "Large-scale and high-yield polyculture technology of crucian carp" and "Study on industrialized seedling raising technology of freshwater fish" also won the second prize of Tianjin Science and Technology Progress Award; "High-yield technology of main carp" has been widely adopted by many aquaculture units for many years and has achieved great economic and social benefits. With the support of the national "863" project, the digital integration and expert system of aquaculture were studied, among which "Development and application of agricultural expert system" and "Tianjin freshwater aquaculture network expert system" won the first prize and the second prize of Tianjin scientific and technological progress respectively.

(2) Genetic breeding of aquatic animals: The healthy breeding of famous new varieties is also an important research field in this direction. Intensive and facility-based healthy culture of famous economic fish, such as sturgeon-shaped fish, precious perch, American shad, Australian silver perch, tongue sole, spotted grouper and D- ray, has been carried out successively, as well as artificial simulation and creation under the ideal mode of different varieties. The above research can not only improve the yield, but also provide reference for the industrialized seedling raising, intensification, facility and healthy breeding of other tree species.

(3) Aquatic animal nutrition and feed science: Exploring the optimal requirement of aquatic animal nutrition has always been the main direction of this discipline. The artificial compound feed of Trionyx sinensis, Cyprinus carpio and China shrimp was studied from the main breeding varieties in the north, and the optimized feed formula and premix formula were obtained, and the scientific breeding technology under different breeding modes was explored. Among them, "Study on artificial compound feed for prawns" took the lead in discussing the protein demand of prawns in China from the amino acid level, ranking the leading level in China; "Carp artificial compound feed" won the second prize of Tianjin Science and Technology Progress Award; "Shrimp premix" was authorized by the national invention patent.

In recent years, with the rise of healthy breeding technology theory and the adjustment of Tianjin's industrial structure, some new breeding varieties have been introduced. Research and development of famous, special, excellent and new varieties of high-efficiency, environmentally-friendly artificial feed and premix, such as Litopenaeus vannamei, Australian rare perch, Australian silver perch, American shad, Cynoglossus semilaevis, spotted grouper, culter ilishaeformis, white crucian carp, southern catfish and Pseudobagrus fulvidraco. It has been carried out one after another, and it is a new variety. At the same time, the development of colorants is also an important research field in this direction. The "Beijing Ornamental Fish Industrialization Promotion System Construction" and "Ornamental Fish Feed Development" were carried out, which promoted the application of colorants in ornamental fish. The study of "Preliminary Study on Growth, Body Color and Metabolism of Red, White and koi fish by β-carotene" and "Coloring and Growth Test of Red, White and koi fish by Red Worm Feed" provided theoretical basis for the application of pigments in red, white and koi fish.

(4) Prevention and treatment of aquatic animal diseases: Taking the mainstream aquaculture varieties in northern China as the research object, this study carried out studies on carp hemorrhagic disease, carp scaling disease, PARALICHTHYS olivaceus ascites disease, PARALICHTHYS olivaceus albinism and fish myxosporosis, obtained relevant pathogenic organisms, pathogenesis and histopathological changes, studied the relationship among pathogenic microorganisms, animals and ecological environment, and the epidemic law of diseases, and screened out effective prevention and treatment. The cloning, expression and purification of tumor necrosis factor TNFα gene of red snapper, tumor necrosis factor TNFα gene of rainbow trout and cytokine MSH gene of PARALICHTHYS olivaceus were studied, and their pathogenesis and immunomodulation were discussed from the molecular level, and the immunomodulation and mechanism of nitric oxide synthase in fish were explored from the immunohistochemical point of view, which was at the leading level in China.

Using immune enhancers to enhance the ability of animal disease prevention is a research hotspot in this direction in recent years. The research on improving the immune function of cultured aquatic animals by using Chinese herbal medicines and their extracts, microbial products and chemical synthetic substances has been widely carried out, which provides a material basis for enhancing the disease resistance of animals. The research and development of Chinese herbal medicine for prawn and immune enhancer for Litopenaeus vannamei have been carried out successively, which has promoted the application of Chinese herbal medicine in aquaculture. Related research, such as "the efficacy of Houttuynia cordata Thunb. Studies on Antioxidant Capacity and Two Immune Activity Indexes of Penaeus vannamei and Effects of Live Yeast Derivatives on Antioxidant Capacity and Some Immune Activity Indexes of Haliotis diversicolor provide theoretical basis for Chinese herbal medicine to improve animal immune level.

(5) Protection of fishery resources and environmental restoration: according to the present situation of fishery resources and environment in Bohai Bay, the response of fishery organisms to environmental factors should be carried out; Key technologies and applications of fishery resources protection; Pollution dynamics of toxic and harmful substances such as red tide toxins, persistent organic pollutants and heavy metals; Ecological control theory and key technologies; Environmental detection technology of fishery waters; Study on ways and methods of ecological restoration of degraded fishery ecosystem. Explore a new model of modern fishery development in coastal cities that adapts to the rapid development of industrialization and urbanization. It provides reference for the fishery development of the newly industrialized coastal cities.

(6) Fishery resource management: taking the field of fishery resource management as the application background, taking computer-related theories as the research basis, taking information processing technology and its application as the realization means, and taking highly controllable fishery under the condition of scientific and technological development as the research goal, the achievements of information processing technology are effectively applied to fishery management planning and the establishment of fishery resource reconstruction evaluation system. It aims to promote the development of fishery standardization mode, fishery management informationization, intelligence and overall planning, and enhance the concept and mode of fishery management. At the same time, according to the problems exposed in the application of informatization theory and technology in fishery management, the theory and technology of information processing and information display are improved and innovated, which makes the theory and technology of fishery management informatization more perfect. The main research contents include fishery planning and management, fishery information technology development, fishery law and management model research, fishery resources reconstruction technology system construction and so on.

(7) Fishery biology and germplasm resources: In view of the serious pollution around Bohai Sea, Haihe River, inland areas and counties in Tianjin, which led to the serious decline of fishery resources and a series of ecological environment destruction, research work was carried out to improve fish production and promote the restoration of fishery ecological environment. Facilities, intensification, large-scale aquaculture and information-based fisheries have always been the strengths of this direction, which have provided effective technical means for industrial seedling raising of important economic varieties, and also enriched and developed the theoretical research of healthy aquaculture and protected fisheries. The genetic background of the main cultured varieties of seawater and fresh water and the study of fishery gene resources are also the focus of this direction. To study the biology, karyotype, isozyme and molecular biology of fish, shrimp, shellfish, algae, newly developed wild cultured species of seawater and fresh water and introduced species in Bohai Rim region, so as to find out their genetic background and establish new germplasm standards.
