鳗鲡 (Angulla japonica Jemminck et Schlegel) commonly known as: Japanese oystercatcher, river bream, squid, white pecker species: Amaranthus, suborders, Amaranthidae is a special cultured fish, its breeding has not been conquered, but completely relying on fishing naturally Seedling culture, so the seedlings are called "soft gold." Therefore, the eel is raised here as a chapter. For the raising of the seedlings and transportation of the seedlings that have just been harvested, the wastes shall be removed before the transportation and used for temporary maintenance after the screening to remove the excrement in the seedlings of the seedlings to prevent the pollution of the water quality in the transportation and to increase the seedlings during transportation. The survival rate. Temporary raising methods of seedlings include temporary water conservation, temporary storage of cages and temporary maintenance of cement pools. 1) Drenching water conservation: The seedlings will be kept in the containers, washbasins, tubs and other containers, and will be sprayed once every 1-2 hours to keep the seedlings moist so as to ensure that the seedlings can perform skin respiration. This method can only be kept for 2-3 days. 2) Cage holding: The polyethylene net cage with the size of 211.5m is placed in a river or pond with good water quality. The holding density is controlled at 1-6kg/m2 depending on the temperature, and the survival rate can reach more than 90%. This is generally Instructions. 3) Temporary maintenance of cement pool: specifications 840.8m, about 25 tons of water storage, requiring good drainage, oxygenation and running water conditions, at 12-17°C, DO 4mg/l or more, PH 7-8, density is controlled at 8 -4kg/m2, the survival rate can reach 95%. There are two methods of transporting seedlings: transporting water through the carton box and transporting the bag in oxygen. Carton box water transport: the use of 50358cm three boxes, the upper water, the middle layer seedlings, the lower is the chassis, seedlings in each seedling box installed 1-2kg, and then with the chassis together and transported tightly. Oxygen-sealed and sealed plastic bags: 7050cm double-layer plastic bag, water-filled 1-2kg/bag, two bags in one box after inflating, one ice bag in the middle, and 1-2kg ice cubes. The breeding of seedlings of the quail species is a process of raising the white larvae having a body weight of about 0.1 g to a body weight of 10-20 g. 1) Seedling stocking and feeding training Seedling stocking should choose seedlings with neat specifications, lively and lively, non-invasive body, and smooth and non-white color. Before stocking, the dead and wounded seedlings should be picked up, and then the seedlings should be Dianchi disinfection, the water temperature of 20 °C is appropriate, the open pond put the amount of 0.2-0.3kg/m2, the temperature of the pool 0.5-1kg/m2 is appropriate. In order for squid to change its habits of morning and evening feeding and eating natural foods, it is necessary to train them from a young age, which is the key to the success of breeding. Can use light to induce and change the feeding method step by step to train. 2) Grazing and Feeding of Seedlings by Stages Because of their strong or weak competition power, the size of individual individuals in the rearing period is obviously different. Therefore, different types of sub-hoppers must be selected in time, and they should be stocked separately in the first-level pool and the second. In the grade pool and the tertiary pool, this is an important measure to increase the survival rate and accelerate the growth.鳗鲡 鳗鲡 鳗鲡 åœ åœ åœ åœ åœ åœ åœ åœ åœ åœ åœ åœ åœ åœ è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš è¦åš æ“作 æ“作 æ“作 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并.
