Description

Automatic water exchange device for biological planktonic breeding pool

technical field

The invention relates to an automatic water changing device for a pool, in particular to an automatic water changing device for a breeding pool in the stage of biological plankton.

Background technique

Since the end of the 1980s, my country has leapt to become the world's largest fishery country and the world's largest aquaculture country, and the output of both has ranked first in the world until now. Among them, aquaculture develops the fastest, and the annual growth rate of output is much higher than the world average annual growth rate. Seed breeding is an important link and key technology in aquaculture. There are various practical problems encountered in the seed breeding process, such as the degradation of germplasm resources, water quality problems in aquaculture, feed supply and nutrition, and so on. Among them, changing the water body in the culture pond is a daily task in industrialized aquaculture, but it has become an obstacle or problem at a specific stage of some cultured species.

Most marine benthic organisms have the planktonic larval stage, and most of the aquaculture species in my country, such as shrimp, shellfish, snails, and copepods used as biological bait, have this special growth and development stage. Most shrimps go through four stages after hatching from eggs: nauplii, zoan larvae, mysis larvae and larvae. Nauplii and zoan larvae are typical planktonic forms; shellfish have a typical two-phase life cycle : Planktonic larvae stage and attached larvae/adult stage; general snails have three larval developmental stages: vecoid larvae, late vegophyllum larvae and prostrate larvae, and vecoplankton larvae are typical planktonic larvae; the planktonic larvae stage of copepods is a larval stage. These planktonic larvae have a common feature: the swimming ability cannot compensate the displacement caused by the slight water flow, that is, the individual is transferred with the water flow.

Therefore, planktonic larvae are the stages that must be experienced in raising seedlings of the above-mentioned cultured species. During the cultivation period, changing the water in the culture pond is a daily compulsory course, and planktonic larvae with insufficient swimming ability will densely adhere to the surface of the filter (sieve silk) with the flow of water. Death by suffocation or loss caused by being discharged out of the pool with water. Taking thick-shelled mussels as an example, the early stages of D-shaped larvae need dense sieves (300 mesh) to manually filter the water slowly, which consumes a lot of labor and time. The subsequent breeding costs will also increase. In the actual seedling raising process, artificial continuous washing is used to prevent planktonic larvae from densely attaching to the sieve silk screen covered by the mouth of the pumping pipe until the end of water change.
