Lake net enclosure crab technology

I. Breeding conditions 1. The net perimeter construction adopts double-layer net enclosures. The two-tier nets are separated by 5 meters. The bamboo nets (trees) are used as the fixed piles around the net perimeter. The distance between each pile is 2 to 3 meters, and the cutting will be good. After the ethylene mesh is sewed, the rope is tied to the pile and pulled up and down and left and right to form a plane. The bottom of the mesh is fixed with a gabion and a ground anchor so that the foot of the net adheres to the bottom mud. The gabion is pressed into the bottom mud by 20 cm. It is 1 meter to 1.5 meters above the water surface. At the top, it is equipped with a "T" type mesh. The upper side of the mesh is provided with a mesh box of 30 cm to 50 cm of a vertically downward-looking calcium plastic plate, which is tightly attached to the mesh. 2. After the planting of snails and snail nets is completed, the large ferocious fish in the culture area will be caught by an electric catcher, and Elodea will be planted from February to March, with 2 to 3 kg of grass stems per square meter. Divided into several bundles with foot into the mud in the bottom of the lake, rooting and growth can be achieved in about 1 month to achieve luxuriant growth. At the same time, several wormwood and reed and other emerged plants are transplanted, and the total surface area on the water accounts for about 1/5 of the total area. Aquatic peanut community. Before the Ming and Qing Dynasties, put fresh snails into the enclosure, 500 kilograms per mu. Second, aquaculture operating technology points 1. Seedstock stocking in the snails snails after 1 month, can also be surrounded by a small piece of crab species in advance. Sets of fingerlings are stocked from May to June. Put the crab species with potassium permanganate or salt, fish meal with bleach and other drug bath sterilization 10 minutes to 30 minutes. Choose the authentic Yangtze River water quality dung beetles, require the same specifications, about 160 per kilogram, control the stocking rate per acre within 600, nesting about 5 centimeters of cod, 2 cm to 3 cm of stingray and other large specifications For seedlings, the mu stocking amount is 20 and 50 respectively. 2. Regularly replenish aquatic plants and snails to make crabs eat mainly natural baits. In order to grow snails in the early stage, some fresh snail meat and small junk fish can be properly fed, and feeds made from pumpkin, potato silk, fresh fish, fish meal, and bean cakes are fed once a day to supplement the nutritional deficiency of natural foods. , to ensure that the crab body fat. 3. The day-to-day management is mainly to do a good job of anti-escape work. In the early stage of stocking of crabs, young crabs are most likely to escape because of environmental changes. Therefore, in the two weeks after stocking, it is necessary to inspect the effect of preventing the escape of the nets every day, and to prevent the crabs from escaping from the damaged place or under the platform. In the latter period of cultivation, due to the role of the law of reproduction of migrating crabs, the chances of escape from the river crab increase, and strict precautions must be taken to ensure that the anti-escape facilities are intact. During the flood season from July to August, do a good job of reinforcing the network facilities, prepare a certain amount of flood prevention materials, and prevent wind and waves from scraping the facilities. Secondly, we must do a good job of cleaning around the perimeter of the network to remove the debris that has accumulated around the perimeter. 4. Begin to catch and market in October. The specific dates are based on the growth and climate conditions of the crabs in the netting area. Fishing tools include cages, nets, and wire mesh.

Shandong ginger plants in April each year, harvest in the end of Oct. After harvest, ginger can be stored in the cellar or cold storage, keep fresh and perennial supply.
