Sinonovacula constricta sowing type culture method for experiments

Abstract

The invention discloses a sinonovacula constricta sowing type culture method for experiments. The sinonovacula constricta sowing type culture method comprises the following steps: S1, removing impurities from bottom mud, disinfecting the bottom mud with quick lime, and exposing the bottom mud under the blazing sun; S2, placing the disinfected bottom mud in a breeding box, inserting a plurality ofbreeding pipes into the breeding box, wherein the height of the breeding pipes is larger than the thickness of the bottom mud; S3, adding the seawater disinfected by the bleaching powder into a culture box; S4, putting the axe foot end of the sinonovacula constricta fry facing downwards into the breeding pipes, and performing oxygenated culture; S5, regularly changing water, and feeding the mixedsolution of chaetoceros and chrysophyceae three times every morning, noon and evening. The method can effectively prevent local sinonovacula constricta from being too high in density, and the death rate is reduced. Meanwhile, the problem of mechanical damage during sampling can be effectively solved, and the damage rate is almost zero; the labor can be greatly reduced, and all bottom mud does notneed to be turned over blindly; the problem of diffusion of decayed bottom mud after the sinonovacula constricta dies can be effectively solved, the healthy breeding environment is guaranteed, and generation of waste bottom mud is reduced.

Description

technical field [0001] The invention relates to the technical field of cultivation methods for razor clams, in particular to a sowing cultivation method for experimental razor clams. Background technique [0002] As one of the four traditional cultured molluscs in my country, razor clam has the advantages of low cost, short breeding period, and rich nutritional value, and is deeply loved by people. Therefore, more and more researches on razor clam are carried out. The razor clam is a typical buried shellfish, and the depth of buried sand is deeper than that of other shellfish. It must have a substrate in order to survive well in the experimental culture. The existence of the bottom causes the biggest problem in the experimental breeding is sampling. When sampling, the razor clam must be dug out from the bottom mud. The damage rate to the razor clam is relatively high during the digging process, and it consumes more energy. Once the shell of the razor clam is damaged, it will...

Problems solved by technology

The existence of the bottom causes the biggest problem in experimental breeding is sampling. When sampling, the razor clam must be dug out from the bottom mud. The damage rate to the razor clam is relatively high during the digging process, and it consumes more energy. Once the shell of the razor clam is damaged, it will be serious. Affect the growth behind it, easily lead to death

The dead razor clams will rot in a short time, which will cause the sediment around them to rot and become smelly, which will affect the cultivation of other razor clams and cause a vicious circle
