Problems solved by technology

The traditional way of raising seedlings is to put the host fish infected with the larvae directly into the nursery pond to remove the seedlings. However, there are differences in the accumulated temperature required for the metamorphosis and development of the larvae of different species of river mussels. Generally, it takes 8-9 days for the water temperature of 20°C to Seedling removal, that is, the accumulated temperature is 160-180 degrees per day, and due to the poor synchronization of the development of the larvae, the time to remove the seedlings generally lasts for 2-3 days. Therefore, this process has the following disadvantages: (1) Infection The host fish of the larvae (hereinafter referred to as the host fish) has been cultured for too long, and the risk of death increases; (2) The residual bait and feces produced during the cultivation of the host fish affect the survival rate of the detached juvenile mussels; (3) The host fish is affected by production. The interference of activities will stir the bottom of the pond, causing the juvenile mussels to be lost with the overflow of the water; (4) Some host fish have the habit of eating juvenile mussels, and a large number of juvenile mussels will be ingested; (5) Production activities cause frictional damage between the fish body and the pond wall Death from disease or stress; (6) The number of juvenile mussels in the cultivation pond cannot be evaluated, and the density may be large or small, and precise cultivation cannot be achieved
In addition, for the artificial breeding research of some rare and endangered species, traditional breeding facilities are not conducive to fine-grained tracking research, such as host fish screening, etc.

Abstract

The invention discloses a young freshwater mussel fry removing and fry precise breeding device and a manufacturing method. The young freshwater mussel fry removing and fry precise breeding device comprises a device host fish temporary breeding system, a young mussel fry removing and collecting system, a fry precise breeding system, a temperature control system, a water inlet system and a water outlet system. The host fish temporary breeding system comprises a host fish temporary breeding box body, a host fish temporary breeding box body supporting frame and a host fish temporary breeding isolation net arranged in the host fish temporary breeding box body. According to the device, host fish breeding, young mussel fry removal and collection and fry breeding are creatively and organically combined and mutually independent. According to the method, the cultivation process from metamorphosis development of glochidia on host fish bodies to before young mussels fall off is independently carried out in the host fish temporary breeding box, and meanwhile, the isolation net is arranged in the host fish temporary breeding box to isolate the host fish from the box bottom. Compared with the traditional manner of directly putting the host fish into a cement or brick breeding pond for fry breeding, the device has the advantage that firstly, the risk that the fish bodies rub or collide with the pond wall to be injured and infected and stir polluted water at the bottom of the pond to die can be reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a device for removing seedlings of clam juveniles and precise cultivation of seedlings and a production method. Background technique [0002] The reproductive season of river mussels is generally in spring and summer. The sperm eggs are fertilized in the gill cavity of the external branchial flap. After the fertilized eggs develop into mature larvae, they are expelled from the body and parasitize on the gill filaments or soft fin rays of the host fish by using the silk and hook teeth. After a short period of parasitic metamorphosis, it develops into juvenile clams, thus completing natural reproduction. The traditional way of raising seedlings is to put the host fish infected with the larvae directly into the nursery pond to remove the seedlings. However, there are differences in the accumulated temperature required for the metamorphosis and development of the larvae of differ...
