Problems solved by technology

The water temperature in spring in the area north of the Yangtze River is low, which cannot reach the water temperature required for the reproduction of California perch. The local artificial breeding of fry will take until after April. Even if the fry are purchased from Guangdong, it will take until March and they need to be raised indoors temporarily. The outdoor water temperature rises to about 15°C before it can be put into the pond. In these cases, there is a problem that th

Embodiment 1

[0037] In 2018, the zero-discharge California perch temperature-controlled nursery method was adopted for the cultivation of California perch. The breeding process is as follows:

[0038] The zero-discharge California perch temperature-controlled nursery method comprises the following steps:

[0039] S1, site selection and processing: the implementation of the present invention can be carried out in any place where a factory aquaculture workshop is built, and a breeding area and a water treatment area are delineated in the factory aquaculture workshop, such as figure 1 As shown, a plurality of nursery ponds 1 and a plurality of cultivation ponds 2 are set in the breeding area, an artificial wetland is set up in the water treatment area, and a circulating water channel is arranged around the surrounding side of the breeding area, and in the circulating water channel A gate 3 corresponding to the seedling pond 1 and the culture pond 2 is set on the ring side, and the nursery pon...

Embodiment 2

[0058] In 2019, the zero-discharge California perch temperature-controlled seedling method was adopted for the cultivation of California perch. The differences between the cultivation process and Example 1 are:

[0059] When growing seedlings under temperature control, in step S1, in January 2019, the nursery pool and artificial wetland were fully enclosed with plastic film for heat preservation, and the plastic film above the nursery pool was 2.5m higher than the ground;

[0060] In step S4, disinfection and cleaning are carried out 5 days before fry purchase, and quicklime is used for thorough disinfection;

[0061] In step S6, the period when the fry is released is March 2019;

[0062] After the follow-up breeding of large-scale fish species of California sea bass, in the middle and early October, most of the California sea bass grow to about 400g / tail, which has reached the market size and can be marketed.

[0063] Others are the same as embodiment 1.

[0064] In 2019, t...

Abstract

The invention discloses a zero-emission micropterus salmoides temperature-control fry breeding method, and belongs to the technical field of aquaculture. The method comprises the steps of site selection and treatment, installation of a filtration device and a heating pipeline, artificial wetland plant cultivation, cleaning and finishing of a fry breeding pond, water temperature control, fry putting, breeding management, large-specification fingerling breeding and the like. Industrial circulating water facilities are utilized, through the combined application of the water temperature control technology and the water quality treatment technology, micropterus salmoides industrial temperature-control fry breeding is carried out in late winter and early spring, after large-specification fingerlings are bred, the fingerlings are bred outdoors in different ponds, and the market specification can be achieved at the end of September. According to the method, the large-specification micropterus salmoides fry can be bred so as to achieve the goal that micropterus salmoides is bred and sold in the market in the current year; besides, feeding of chilled fresh fishes is avoided in the whole breeding process, and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a temperature-controlled seedling raising method for zero-emission California perch. Background technique [0002] As the construction of ecological civilization has risen to a national strategy, facing the severe situation of tightening resource constraints, serious environmental pollution, and ecosystem degradation, it is necessary to establish the concept of ecological civilization that respects, conforms to, and protects nature, and takes the path of sustainable development. The traditional aquaculture industry takes the path of high input, high output, and high discharge, which has low utilization rate of water resources, high pollution, and is not friendly to the environment. [0003] Modern industrialized aquaculture is the general direction of industrial development. Its basic idea is to achieve zero emissions (Reduce, Reuse, Recycle). The basic requirement is to esta...
