Embodiment 1

[0020] A method for breeding and researching fine varieties in a canvas fishpond comprises the following steps:

[0021] Step 1: Select the test site and build a canvas pool. The frame is surrounded by galvanized sheets, and canvas is laid inside. The color of the canvas is dark blue;

[0022] Step 2: Build a closed water circulation, disinfection, sewage discharge, and sewage treatment system. Set up three disinfection equipment equidistant above the canvas fish pond, install a filter with a higher density at the sewage treatment device, and set up three feeding tables outside the canvas fish pond. An aerator is installed on the feeding table;

[0023] Step 3: Select good and best-selling fish species in the market and conduct breeding observation. The fry density is 30 to 50 fish per square meter;

[0024] Step 4: Feed three times at 7:00 am, 13:00 noon, and 6:00 pm every day. The feed is mixed with iron, manganese, and copper additives, and the protein content of the feed ...

Abstract

The invention discloses a breeding and research method for breeding good varieties in a canvas fishpond. A test site is selected, and the canvas fishpond is built; the frame is defined by galvanized plates, and canvas is laid in the frame and is dark blue. A closed water circulation, disinfection, pollution discharge and sewage treatment system is constructed; three disinfection devices are arranged above the canvas fish pond at equal intervals; a filter screen with relatively high density is mounted at the sewage treatment device; three feeding tables are arranged on the outer side of the canvas fish pond, and aerators are arranged on the feeding tables; the feed is doped with an additive containing iron, manganese and copper elements; physical and chemical indexes and yield indexes of a water body are measured according to factors such as growth conditions, survival rates and growth speeds of the fries; data are analyzed and compared, project summarization is performed, and the integrated breeding key matching technology is developed. The invention has the advantages that a closed water circulation, disinfection, pollution discharge and sewage treatment system is constructed, the sanitation of a fry growth environment is ensured, and the survival rate of fries can be greatly increased.
