Nereis biological feed culture tank

Abstract

The invention relates to the technical field of nereis cultivation culture tanks, in particular to a nereis biological feed culture tank. The nereis biological feed culture tank comprises a drainage plate, a screen laid on the drainage plate, used for placing culture medium and preventing the culture medium from running away, as well as a culture medium layer laid on the screen, the drainage plate, the screen and the culture medium layer are sequentially arranged above the bottom of the culture tank, the culture tank is provided with a water outlet, and the water outlet is arranged below the drainage plate. Compared with the prior art, the culture tank provided by the invention utilizes mobilization force of discharging water at the bottom of the culture tank, so that feed fed into the culture tank can better go deep into the culture medium, utilization rate of feed solute is improved, and efficient nereis cultivation is realized; besides, the culture medium layer can effectively avoid external germs from invading a nereis system, and when water is changed and residual feeds and juice in the culture tank are washed, the culture medium layer stays on the screen and is difficult to run away while the residual feeds and juice on the culture medium layer can be rapidly and efficiently washed away by running water, so that a clean and sanitary growth environment is provided for nereis.

Description

technical field [0001] The invention relates to the technical field of clam worm breeding and cultivation ponds, in particular to a clam worm biological feed cultivation pond. Background technique [0002] As a high-quality seafood, prawns are popular in domestic and foreign markets. The demand for high-quality prawn products is increasing, and prawn farming has become a dominant industry in my country's fishery. However, in recent years, due to the continuous degradation of the quality of prawn species, the lack of good alternative species and the lagging of breeding technology for improved species, it is difficult to breed high-quality prawn seedlings. High-quality shrimp seedlings have become a bottleneck factor restricting the healthy development of the shrimp farming industry, and healthy broodstock with well-developed gonads is the fundamental guarantee for the production of high-quality seedlings. [0003] Nutrient bait is a key factor in the cultivation of broodstoc...

AI Technical Summary

Problems solved by technology

However, there are the following problems in the use of biological feed such as live clamworms: (1) biological feeds such as live clamworms are carriers of prawn white spot bacteria, taura bacteria and various germs, and can transmit germs and germs to broodstock and pass them on to (2) The residual bait and juice of live clamworm and other biological feeds are easy to pollute the aquaculture water; these factors limit the application of live clamworm and other biological feeds in broodstock culture

And, in the prior art, soil is mainly used as the culture medium of live clamworms, but there are a large amount of biological germs and harmful substances in the soil, which not only makes the live clamworms easy to carry germs and cause diseases, but also the soil is easy to lose so that it is not easy to remove. The residual bait and juice of the bait in the soil should be cleaned up in time, thus affecting the hygienic environment of the culture medium
