Aquatic products-- chilled processing technology for fishing tuna
Tuna is a highly swimming marine fish with delicious meat and high nutritional value, so it is deeply loved by consumers, so it has become one of the key fishing targets in various fishing countries. First, the treatment on the deck 1, to avoid blood stasis of the fish: after the fish on the deck, do not let it jump, so as not to cause blood stasis in the body. After congestion, it can cause muscle damage of 5 times the area, especially in the abdomen. The way to deal with it is to put it on the carpet, hold the fisheye with both hands, or hit the fish on the head with a hammer, but be careful not to

Processing of quick-frozen large silverfish
Quick-frozen silverfish are exported to Japan, Southeast Asia and Europe, especially popular with Japanese consumers. With the continuous improvement of the output of large silverfish in the reservoir, quick-frozen big silverfish has become one of the export aquatic commodities with high exchange rate in China. The main results are as follows: 1. Fresh-keeping and transportation of raw fish the large silverfish has a small body and thin skin, which is easy to rot and deteriorate, and the production is highly seasonal. In order to ensure the quality of silverfish, when fishing, you can disembark with ice and keep it fresh at the first time. The specific method is to first select and classify the big silverfish caught on the ship.

Processing technology of large silverfish (1)
Large silverfish, also known as noodle fish, was widely distributed in the middle and lower reaches of the Yangtze River and affiliated lakes. Its meat is delicious and nutritious, and it has a special fragrance of cucumber. The large silverfish is generally about 20 cm long and has no bones and no thorns. It is a kind of small and valuable fish with high economic value and is very popular in domestic and foreign markets. This paper introduces the processing methods of two kinds of large silverfish: first, the processing of quick-frozen silverfish 1. Preservation and transportation of raw fish the big silverfish has a small body and thin skin, so it is easy to deteriorate.

It is a kind of small and valuable fish with high economic value, which is very popular in domestic and foreign markets. From 1985 to the early 1990s, the reservoir transplanting and proliferation of large silverfish has been carried out in an all-round way in China and achieved success, its distribution area is constantly expanding, and the output is increasing day by day, how to do a good job of silver.

Prevention of fish hypoxia in winter
In winter, fish in ponds need dissolved oxygen to maintain slow respiration although their feeding activity decreases. Dissolved oxygen in ponds comes mainly from phytoplankton photosynthesis and direct dissolution of oxygen in the air into water. However, in the cold winter, once the water surface of the pond freezes, the oxygen in the air cannot be dissolved in the fish pond. When snow covers the ice surface, sunlight cannot directly shine into the pond water, and green plants in the water cannot carry out photosynthesis and produce oxygen. And most fish gather at the bottom of the water in winter,

Methods of preventing fish from anoxia in winter
In winter, although the intake of fish in the pond decreases, they still need a certain amount of dissolved oxygen to maintain slow breathing. The dissolved oxygen in the pond mainly comes from the photosynthesis of phytoplankton and the oxygen in the air dissolves directly into the water. However, in the cold winter, once the surface of the pond freezes, the oxygen in the air cannot dissolve in the fish pond. When heavy snow covers the ice, the sun cannot shine directly into the pond water, and the green plants in the water cannot carry out photosynthesis to produce oxygen. And most of the fish gather at the bottom in winter, if the water quality is poor,

How to do fish pond hypoxia in winter? How to cure?
In winter, the activity of fish is reduced. Although the oxygen demand is not high, the water surface cannot directly dissolve oxygen in the air due to ice formation in the fish pond. In addition, the oxygen production of plants such as aquatic plants in the water body decreases due to temperature decrease and photosynthesis weakening. It is easy to cause water pollution.

Artificial multiplication technique of large silverfish in Hongshan Reservoir
Hongshan Reservoir is located in the lower reaches of Laoha River in the northeast of Chifeng City. it is a large plain reservoir integrating flood control, irrigation and aquaculture, with a rain area of 24500 square kilometers and a total storage capacity of 2.56 billion cubic meters. the fish culture area of the reservoir is 80, 000 mu ~ 130000 mu in low water season and high water season. The fertilized eggs of large silverfish were introduced into the reservoir in 1995, and the fishing yield reached 2.5kg/ mu in 1998, and the yield decreased in the following two years, but in recent years, due to the adoption of more perfect proliferation management measures, the resources have been gradually restored.

Processing technology of yellowfin tuna
Yellowfin tuna is an oceanic fish, generally living in tropical and temperate waters, its main habitat is usually in the depths of 50m~250m water, and its depth also depends on the season and sea level. The catches of tuna longline operations are mainly yellowfin tuna and bigeye tuna. These two kinds of fish account for more than 80% of the catch and have high commercial value. Bigeye tuna is usually refrigerated and processed into sashimi, while yellowfin tuna is frozen on a frozen boat and sold to fish companies for processing into fish slices for sale. Yellow fin gold

Processing technology of swordfish
Swordfish (xiphiasgladiuslinnaeus, Commonswordfish) is a large deep-sea fish, named for its upper and lower jaw shape, thick in the middle and thin on both sides, like a sharp sword. But because of its high speed, it is called swordfish like an arrow away from the string. Distributed in the Indian Ocean, Atlantic Ocean and Pacific Ocean, the American coast of the western Atlantic is the main producing area of swordfish, which is mainly caught by longline fishing, and most of the individuals are about 10~100kg and above 100kg.

Release technology of silverfish in reservoir
As far as possible, the choice of release site is in the reservoir bay with a certain distance from the shore, a water depth of about 2 meters, and rich in small-scale bait organisms such as hard sediment or gravel bottom and insects, and several delivery sites should be selected at the same time to avoid failure caused by improper delivery of one point. Fish egg delivery method when the fertilized eggs are transported to the destination, the nylon bag containing the fertilized eggs is first put into the water. When the water temperature in the bag is basically the same as the water temperature in the reservoir (the temperature difference is less than 3 ℃), the fertilized eggs are dispersed into the water slowly and evenly, and each input point should have a certain standard.
