Embodiment Construction

[0039] 1. Construction of Songjiang perch breeding and breeding workshop system that simulates the natural ecological environment

[0040] 1. Migration pool construction

[0041] The shape of the pool is like a long river, simulating the river ecosystem in nature. The construction materials of the pool are cement concrete, glass steel, etc., the aspect ratio is 3:1~5:1, and the area is 20~50 square meters; the water inlet pipe is at one end, the diameter is 32~50mm, and the water inlet direction is parallel to the long side defense line; The drain pipe is at the other end, and the drain pipe is 90~160mm. The height of the pool is 50~80cm, and the bottom of the pool has a slope from the water inlet to the outlet, and the slope of the bottom of the pool is 20‰~30‰.

[0042] 2. Construction of breeding ponds

[0043] The shape of the pool is round or square with rounded corners, simulating the lake ecosystem in nature. The construction materials of the pool are cement concret...

Abstract

The invention belongs to the technical field of aquatic culturing engineering, and particularly relates to a trachidermus fasciatus breeding and culturing workshop system for simulating the natural ecological environment. A workshop system for simulating the field habitat is built according to the ecological habit of trachidermus fasciatus, and comprises a hard ecological environment system and a soft ecological environment system. The ecological environment built by the system can completely meet the requirements of trachidermus fasciatus in each period, such as breeding, migration and growth, so the scale production of full-manual breeding and culturing of trachidermus fasciatus is realized. The system can continuously build and expand the manual species of trachidermus fasciatus, and meet the requirement of trachidermus fasciatus fries, fingerlings and adult fishes required by science research, enhancement and releasing, and development and utilization. Compared with the conventional intensive culturing mode, the system has the advantages that the construction cost and running cost are greatly reduced, the culturing benefit is greatly improved, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of aquaculture engineering, and specifically relates to a Songjiang perch breeding and aquaculture workshop system (that is, an artificial breeding and aquaculture system) that simulates a natural ecological environment. Background technique [0002] Songjiang perch is a national second-class aquatic wildlife protection animal and one of the four famous freshwater fish in China. It has good scientific research value, ecological value and economic value. Since the 1950s, Fudan University has continued to carry out in-depth research on it, and has achieved many research results. In recent years, breakthroughs have been made in the key technologies of the Songjiang perch series: water flower fry production, desalinated fish fingerling cultivation, bait culture equipment, factory tube barrel system and other technologies, realizing the fully artificial large-scale breeding and aquaculture production of Songjiang...
