Squid, also known as squid, fat mane, mandarin fish, seasoned fish, flower carp, etc., is a genus, genus, carp, is a freshwater fish, tender meat, delicious, high protein content The thorny and famous Chinese and foreign cuisine is a delicacy for feasting on the feast. In recent years, there has been an upsurge in the cultivation of squid. However, due to the livelihood of the squid, which live in the stone joints and caves, it is difficult to catch fish. As a result, the recovery rate of farmed carp is not high, which directly affects the yield and economic efficiency of carp farming. This article describes some methods for farming salmon fishing for your reference. First, net catch carp 1. During the net catching of trout farming or during the fall harvest season, batches of trout farmed in catch ponds can be pulled through the pond. Pulling nets to catch carp is to use a long strap shaped net to surround the pond or a certain area of ​​water, and then towing on the shore and pulling both ends of the dragline and net gear, gradually reducing the encirclement, forcing the carp into the net and being caught. The length of the net is 1.5 times the width of the pool, 1.2 to 1.5 times the depth of the net, and the mesh size is 4 to 6cm. The material of the net is nylon (PA), polyethylene (PE), and Pooh. Polyester (PVA). Before the operation, remove the obstacles in the water, such as wooden piles in the food field, and add a sinker at the bottom of the net so that the bottom of the net is sticky, so that the catfish do not escape from the net. The net pulls quickly from one end of the pool to the other after the net is caught, capturing the squid and moving quickly. In general, a pond catches 2 to 4 nets and can capture 50 to 80% of the carp in the pond. In the production season of carp fry, it can also be used to catch carp seedlings using summer nets or small nets. The mesh size is 0.5 to 1 cm. 2. According to the characteristics of squid inhabiting in micro-flowing water, net traps can be used to catch catfish. The commonly used nets are nets and nets, nets are square, netting materials are made of PE or PA, nets are bent with two bent bamboo crosses at the corners of the net, and the cross is fixed with ropes and bamboo sticks. During the operation, the nets will be placed at the bottom of the inlets of ponds, lakes and rivers, and the area will depend on the size of the inlet. The mesh size will be 4-6 cm. The nets for catching eel fry will be l-2 cm. Due to the stimulation of water flow, the catfish come back to the surface of the water inlet, and they raise the net once every 10-30 minutes to harvest the squid. This method is good for catching at night, and it is usually repeated for several nights to catch ponds. The catch rate of salmon fishing can reach more than 60%. 3. Based on the characteristics of the squid's favorite water flow, Zhang net traps use water to impact and set cage-type nets to catch carp at the inlet and outlet of ponds, lakes, and rivers. Caged nets are cage-shaped. The materials are mostly made of PE and PA. The mesh size is 3 to 6 cm. The net mouth is equipped with a funnel-shaped device. During operation, the net mouth is placed along the direction of the water flow, and the catfish will enter the net when drilling water. In aquaculture ponds with gates, batches of codfish can be caught in a row, and a net can be used to cover the nets. The mesh size is determined by the size of the gate, and the length is 3 to 5 times the width of the net mouth. The mesh is from the mouth of the net to the net. The sac was gradually reduced. The mesh of the sac was about 3cm. The squid was caught about 1cm from the sac mesh. The mesh material was PE and the sac was PA or PE. The net is installed at the gate, and when the water is drained, the fish that have come down with the water are caught. Second, foil fishing gear catch carp 1. Baskets catch salmon during the reproductive season. They like to breed into pairs and drill into the water. They can use this habit to put baskets on lakes or river bays, shallow water areas with plants, or waterways where squids often swim. Fish caught in the basket by mistake. Cylindrical basket, etc., composed of two parts: basket body and inverted whisker. The length of the basket is about 80 to 100 cm. The diameter of the basket is about 70 cm in the middle. The basket is made of bamboo strips and is composed of two half baskets that are relatively symmetrical. Inverted funnel shaped, bamboo raft preparation. Flower baskets can be produced year round, but from March to May is the peak season. When operating, select the fishery and put the basket into the water with a water depth of 0.5 to 1m. If the basket is set in shallow water, the basket must be covered with aquatic plants, and sometimes small bricks or stones are attached to prevent the basket from floating. Was washed away by currents. Basket basket operations, generally after the basket is released, the baskets will be picked up once and for all. 2. Mesh Foil Net Foil is meshed by PE mesh to form a certain shape of net. In the fish's migratory passage, the solution of fish is stopped, and a trap of a certain shape is laid according to local conditions. And was caught. In large ponds, lakes, and rivers where trout is cultured, net fish can be used for catching trout. In the spring, summer and autumn seasons, in open waters such as flowing rivers, lakes, and harbor inlets, they were caught in net foil when the netting foils were used, and when the catfish came back to water or ingested food. 3. The Ecstasy array is composed of bamboo strips, reeds, crop stalks, etc., and is woven into a certain shape of foil curtains. According to changes in the terrain and water conditions, the squid is stopped on the fish's migratory passage, and traps of certain shapes are laid according to local conditions. Inducing squid into the inner, so that it enters the fish or fish nest and was captured. In the spring, summer and early autumn seasons, in the open waters of lakes with polyculture cod fishes, rivers with flowing water, and inflow ports in harbors, there were ecstasy arrays. When the catfish came back to water or ate, they were caught in the ecstasy array and arrested.
