Description

Inlet and drainage device for grass carp larvae culture

technical field

The utility model relates to the technical field of grass carp breeding equipment, in particular to an intake and drainage device for grass carp larvae culture.

Background technique

The larval stage of grass carp refers to the first stage of the late mesoembryonic stage of its life cycle. The larval embryo of the oviparous teleost fish hatches from the egg membrane and enters the larval stage. The main feature of the larval stage of grass carp is that the fry body has fin folds. Most of the newly hatched larvae have a large yolk sac as a source of nutrition, which is called the yolk sac stage. During the yolk sac stage, the larvae complete a series of organ function development related to feeding and digestion, so that they have the conditions to transfer from endogenous yolk nutrition to exogenous sources. Feeding nutrition, most of the yolk sac larvae begin to feed to the outside in a short period of time before the yolk is exhausted, thus forming a mixed trophic period in which endogenous and exogenous nutrients coexist.

The larval stage of artificially bred fry is the stage from the egg membrane just before the lower pond. The cultivation of the larval stage is directly related to the emergence rate of the fry. The existing grass carp larval culture is mostly carried out in cement culture, and most The use of continuous flow aquaculture mode is very wasteful of water resources and does not meet the principle of water conservation. The use of recirculating aquaculture for grass carp larvae has become a new breeding mode, but the recirculating aquaculture mode needs to maintain the water level and water circulation, that is, continuous water supply and release, and the larvae are more sensitive to the shock stimulation of the water flow, which is lacking in the existing equipment. The water intake and drainage device is designed for the larval stage of grass carp, so the utility model designs a new water intake and drainage device.
