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.

What should be caught by fish species management in autumn?
Clear the pond. Transfer the fish to a pond that has been cleaned and sterilized for cultivation. If there are difficulties in the turnover of water sources and fishing ponds, all the fish species can be transferred out of temporary culture, then disinfect the original ponds with 75 kg ~ 100 kg quicklime per mu, and fertilize the water quality according to the conventional method, and return the fish species after the medicine disappears. Separate cultivation. Adjust the fish species according to different specifications, so that the specifications of the fish species in the same pond are the same. Large fish species have large food intake and strong grabbing power, just like small fish species in ponds, small fish will suffer from physical decline because they do not get enough feed. Fish over 16 centimeters

It's good to put the fish in the box in autumn.
After fattening in the pond in autumn, the fish species are generally strong and easy to adapt to the cage environment. At the same time, when the caisson overwintered with large water surface, not only the body weight consumption of the fish species overwintering was less than that in the pond, but also the fish began to eat earlier after overwintering in spring, and the growth period was about one month longer than that of the fish in the box in spring. The growth rate of fish is faster and the yield is significantly increased. Compared with the species in the box in spring, the caisson overwintering species grow about 30% faster and the size out of the box is about 35% larger. Therefore, it is more scientific for fish to overwintering in the box in autumn.

Industrial cultivation of Pelteobagrus fulvidraco larvae by artificial incubation of Artemia
1. The large ridge double row planting method transplants seedlings in the order of 6 inches, 12 inches and 6 inches. Its advantages are as follows: first, the total number of holes per mu (16000 holes) is slightly less than that of monoculture rice, but the yield is increased by ventilation, light transmission and other conditions. The second is to provide more than 7 hours of light every day, increase the water temperature, plankton reproduce and grow rapidly, and create good conditions for providing natural bait organisms for Pelteobagrus fulvidraco. The third is to broaden the activity space of Pelteobagrus fulvidraco, which can kill insects in a large area, fertilize fish manure and increase rice production. two。 Rice management rice cultivation management is strictly in accordance with the "

What are the fish's requirements for water temperature?
The mud carp has higher requirements for the water temperature of the living environment. The optimum temperature for reproduction is 26~30℃, and the optimum temperature for feeding is 14.6~29.4℃. Too high or too low water temperature will reduce the feeding intensity. The cold resistance of mud carp is poor, and a large number of them die when the water temperature drops to 6~7℃. Therefore, the culture of mud carp should take winter heat preservation measures, and the area of culture of mud carp is limited by temperature.

Three methods of fishing natural eel seedlings
There are mainly the following three fishing methods: 1. The net is in the shape of a trumpet tube, with a general length of 9 meters and a perimeter of 6-7 meters, which can be woven with polyethylene thread. The net port gradually shrinks from the net port to the back end, and the end of the net port is connected with a floating seedling collecting box. Set seedling box mesh 50-60 mesh. Zhang Wang should be set on the beach far away from the sluice to collect eel seedlings with the trend. It can be caught at high tide and low tide. Two people worked, one rowed the boat, and the other regularly lifted the seedling box with a small white porcelain basin and scooped out the eel.

Prime time for mixed culture of aconite
Most of the farmers in Chaoshan, Shenzhen, Dongguan and other places in our province can get better economic benefits if they mix the four big domestic fish and tilapia with aconite in freshwater fish ponds. Mixed culture of aconite in domestic fish ponds has less investment and high profit, so it is worth trying to raise four major domestic fish and tilapia. Aconite (scientific name mullet), mainly produced in the southeast coast of China, has a wide adaptability. It can not only live in sea water, but also be cultured in a completely fresh water environment through desalination. Its fry are fished artificially.

Simulating the processing technology of crab meat
Simulated crab meat is a convenient food with fresh sea crab flavor, which is made from haddock. At present, the technical equipment for simulating crab meat in Shandong Province is imported from Japan. Simulated crab meat has a broad development prospect as an aquatic convenience food. At present, the product is mainly exported to Japan and the United States. 1. Technological process: frozen surimi → thawing → ingredients → chopping and crushing → steaming and baking → strips forming → sterilization → cooling → vacuum packaging → rapid low temperature freezing → packing → cold storage 2.

Prevention and treatment of hemolytic ascites disease of bighead carp
With the gradual popularity of bighead carp in the market, most of the ponds in the suburbs of our city have changed from raising bighead carp to raising bighead carp. The yield of bighead carp has grown from dozens of jin per mu at the time of interculture to over 1000 jin per mu at the time of main culture. Due to the increase of bighead carp culture density, the incidence of bighead carp has also increased year by year, and the number of deaths has increased year after year, causing certain economic losses to farmers. Hemolytic ascites disease of bighead carp is a fulminant infectious disease, also known as bacterial septicemia, which is caused by bacteria. Most of the sick fish roam in the pond before they die, with blackened back and the mouth of the diseased fish.

Control of several key points in large size "Yellow River Estuary" hairy crab culture
In order to start the "Yellow River Estuary" aquatic product brand and improve the market competitiveness of the "Yellow River Estuary" hairy crab, Kenli County, Shandong Province, conducted a large scale "Yellow River Estuary" hairy crab culture experiment in the 10,000 mu River Crab demonstration Park in 2005, and achieved good economic and social benefits. Now several key technical issues in the process of culture are discussed with the majority of colleagues. 1. Many units in pond ecology are influenced by traditional concepts. Crab culture follows the method of fish culture to build ponds and raise crabs, but the effect is not good. The survival rate of hairy crabs in the Yellow River Estuary is low.

Remediation and management of fishery production after disaster
Recently, some parts of our province have caused a lot of fish escape from aquaculture ponds due to days of torrential rain, which has brought great losses to farmers. It has become an important work for aquaculture farmers to do a good job in the remediation and management of fishery production after the disaster. The author puts forward the following measures for the majority of aquaculture farmers' reference according to the experience of fishery work for many years. 1. Recovery of fishery production after the disaster. Fish pond purse seine. When the flood recedes, fence around the fish pond at the right time to prevent the fish in the pond from continuing to escape and reduce the loss. 2. Restocking seedlings
