Incubation device quick in fish egg and fish larva separation

Abstract

The invention belongs to the technical field of aquaculture equipment and particularly relates to an incubation device quick in fish egg and fish larva separation. The device comprises a separation cup, a conveying pipe, a sieve, a fish larva tank, a water tank, a water treatment system, a long water pipe, a short water pipe, a connection thread, a water bath kettle and the like. The device recycles water for incubation through a water circulation system, so that consumption and discharge of water for incubation are reduced; water is filtered and then recycled, and accordingly waste of a greatquantity of water resources and environmental pollution are avoided. The incubation device is effective in fish egg and fish larva separation, the fish larva emergence period can be recorded, and fish eggs and fish larvae can be distinguished thoroughly, so that sample damages are low. Multiple incubation devices can be serially connected for use to realize batch separation of a great quantity ofthe fish eggs and the fish larvae.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to a hatching device for rapidly separating fish eggs and larvae. Background technique [0002] At present, people are paying more and more attention to and investing in the field collection and investigation of fish and artificial aquaculture, and the scale is increasing. Many investigators and scientific researchers often collect fish eggs and larvae in different waters. During the sampling process, fish eggs and larvae are often caught by nets at the same time, and effectively separate and screen fish eggs and larvae. At the same time, ensuring the survival rate and vitality of the samples, and the hatching of fish eggs have become the primary tasks of follow-up work. However, because the samples of fish eggs and larvae are small and difficult to distinguish, investigators usually need to use straws to suck out fish eggs one by one from the mixed sample...

Problems solved by technology

However, because the samples of fish eggs and larvae are small and difficult to distinguish, investigators usually need to use straws to suck out fish eggs one by one from the mixed sample of fish eggs and larvae. damage, and there is a greater possibility of missing samples

In addition, the farm incubator occupies a large area and requires a lot of water. It does not form a circulation system, wastes a lot of water resources, causes water stains everywhere, and easily causes electric shock accidents and property losses.
