Incubation system and incubation method of adhesive roe

Abstract

The invention discloses an incubation system of adhesive roe. The incubation system comprises a water source water pipe, a nursery pond, an incubator, a water flow regulating and controlling pipeline and a water treating pond, the water source water pipe is communicated with the water treating pond, the water treating pond is communicated with the incubator through the water flow regulating and controlling pipeline, the incubator is arranged in the nursery pond, the nursery pond is communicated with the water treating pond, an incubation frame is arranged in the incubator, and a set of holes is formed in each corner of the incubation frame. The incubation system solves the technical problems that in the incubation process of perch ribbon-shaped roe, roe mass is accumulated and stacked, and chalaza is easy to break and is broken into fragments or is bound into mass when serious, through the ingenious design of water flow, the chalaza slowly rolls and moves along the periphery of the incubation frame under the action of surrounding microflow, the complete chalaza is guaranteed to the maximum extent, and incubation is carried out in clean running water with enough dissolved oxygen. In addition, screens are arranged on the periphery of the incubator, fry incubated primarily can swim out freely, and the problem of fry emergence is solved well. The method is also suitable for the incubation of other adhesive roe.

Description

Technical field [0001] The invention is a aquaculture field, which involves a viscous fish egg incubation system and incubation method. Background technique [0002] There are three types of fish in the river bass, that is, gold bass ( Perch FlaveScens ), European bass ( Perch Fluviatilis ) And Ili River Perch ( Perch Schrenki ) Among them, the golden bass and European bass are important and precious freshwater economy fish in North America and Europe, and the development and research of the Ili River bass produced in the Ili River and Ermin River in my country is very small.In recent years, in order to make up for the severe exhaustion of river bass fishing resources, more and more North American, European breeding owners and R & D personnel have begun to engage in the development and research of the river bass breeding industry.In the 1990s, my country introduced gold bass from the United States. However, due to many problems such as breeding technology, its breeding industry h...

Problems solved by technology

[0004] The main disadvantages in the existing method include that the egg bands are easily entangled and difficult to unravel, especially in the later stage of hatching, the egg bands soften and become more viscous, at this time, if the water flow is too small, the egg bands stick together and the water exchange is poor , which often causes protozoa to breed, which in turn leads to the reproduction of saprolegnia, resulting in a decrease in hatching rate; if the water flow is too large, the egg belt will easily become fragments and be lost, causing losses
