Aquatic fishingThe use of fishing tools to capture the production activities of economic aquatic animals is the most important component of the aquaculture industry. The ocean, which accounts for about 2/3 of the Earth's surface area, has always been the main place for fishing. The world's marine fishing production generally accounts for about 90% of the total catch, and inland waters account for about 10%. Marine fishing can be divided into coastal, offshore and oceanic (including offshore) operations. The aquatic animals in the coastal and offshore waters are rich in resources and the unit catch is high. The offshore fishing is far from the base, the fishing equipment and technical requirements are higher, the resource density is smaller, and the production cost is higher. Therefore, the catches of countries around the world mainly come from the coast and offshore. Inland waters are harvested from aquatic animals that are naturally grown and artificially stocked in rivers, lakes, reservoirs, etc. Due to the small size of the waters and fishing, a large variety of small fishing gears are used for production.
AquacultureIt is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. It generally involves the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources.Aquaculture has methods such as extensive cultivation, intensive cultivation and high-density intensive cultivation. Extensive farming is to put seedlings in medium and small natural waters, and rely on natural bait to develop aquatic products, such as fish farming in lakes and reservoirs and shallow sea scallops. Intensive cultivation is the use of bait and fertilization methods to grow aquatic products in small water bodies, such as pond fish farming, cage fish farming and fence farming. High-density intensive cultivation uses high-density culture in small water bodies by means of running water, temperature control, aeration and feeding of high-quality bait, so as to obtain high yield, such as high-density fish farming and shrimp.
Refrigerated processingIt refers to a method for inhibiting the activity of autolysis of aquatic products and the growth of attached microorganisms by using low temperature conditions,and slowing down the chemical reaction speeds such as lipid oxidation and non-enzymatic browning, so as to maintain good quality during storage. . It generally includes two methods of refrigerating preservation and freezing and preservation. Processing types of aquatic products, including frozen food processing of aquatic products, dry processing of aquatic products, pickling of aquatic products, processing of fish products, processing of fish products, processing of aquatic products, processing of aquatic products, processing of seaweed food and comprehensive utilization of aquatic products Wait.
