Embodiment Construction

[0017] The following examples will further illustrate the present invention.

[0018] Prepare 8 blue plastic boxes with a length of 65cm×width 45cm×height 40cm and a volume of 140L, 8 hollow cylindrical PVC pipes with a length of 56.5cm, a diameter of 10.7cm, and a thickness of 0.2cm, and 8 inflatable stones. Put the PVC pipe and air-filled stone in a plastic box, fill the box with seawater, add 250g of bleaching powder, stir evenly and soak for 24 hours for disinfection. At the same time, 8 pieces of black sunshade nets (5m in length and 2m in width) were cut out, washed with sea water and exposed to the sun for 1 day. The sterilized blue plastic box, PVC pipes and 8 air stones were washed 3 times with clean seawater until no bleach remained on the equipment. On June 27, put a PVC pipe and an air-filled stone in each plastic box, and then add 100L of clean seawater double-filtered by sea sand and cotton yarn bags into the plastic box. Eight plastic boxes are distributed to ...

Abstract

The invention relates to an indoor bostrichthys sinensis fry intermediate rearing method, and relates to fish fry rearing. According to the invention, pipes and air pumps are placed in a plastic tank; the plastic tank is filled with seawater; bleaching powder is added for disinfection, and the plastic tank is washed by using seawater; a sun shade net is washed by using seawater, and is exposed under sunlight; living water salinity of the fries before capturing is determined; if the living water salinity is different by no more than 10 than the seawater salinity in the plastic tank, the fries are directly placed in the plastic tank for intermediate rearing; if the salinity difference is higher than 10, the fries are subjected to 1-2 days of transition, and are transferred into the plastic tank for intermediate rearing; the fries are not fed the day the fries are placed into the plastic tank; after that, the fries are fed with bait-feed once every morning and evening; fry rearing water is replaced every two days; light intensity is kept below 6lux and seawater dissolved oxygen is maintained at (5.84+/-0.184)mg L<-1>. When fries achieve full lengths of 8.2cm and weights of 8.0g with intermediate rearing, the fries are transferred into a culturing pond and are subjected to adult fish culturing.

Description

technical field [0001] The invention relates to fish seed cultivation, in particular to an indoor intermediate cultivation method for Chinese snakehead snakehead seedlings. Background technique [0002] Chinese snakehead (Bostrichthys Sinensis Lacépède) belongs to Chordata, Vertebrate, Osteichthys, Actinopterygii, Perciformes, Snakehead Suborder Gobioidei, family Eleotridae, Bostrichthys. Commonly known as scorpion tiger, mullet, smear fish, moon fish, earth fish, etc., the back of the body is taupe, the ventral surface is light brown, and the base of the caudal fin has black round spots. Snakena sinensis is a warm-water carnivorous fish in brackish and fresh water in estuaries. It is widely distributed along the northern coast of the Indian Ocean, from Melanesia and Polynesia in the Pacific Ocean in the east, Japan in the north, and Indonesia in the south. China is produced in the Beibu Gulf, the South China Sea, the Taiwan Strait and the East China Sea. Chinese snakehea...
