The breeding method of seven star fish

Abstract

The invention discloses a breeding method of benthosema pterotum. The breeding method includes the steps of 1), selection of a breeding pool, namely selecting the position with a pollution-free underground water source, sufficient in water and convenient for irrigation and drainage to establish the breeding pool and removing weeds; 2), sterilization of the breeding pool, namely sterilizing the breeding pool with a lime drying method and then allowing standing for 7-10 days before water injection; 3), fry dropping, namely selecting strong and vigorous fry with no diseases and injuries and dropping the fry to the breeding pool in early April; 4), feed dropping, namely feeding animal feed of water flea, fairy shrimps and the like in early feeding, and feeding vegetable feed of corn flour, bean dregs and the like in later period, wherein respectively feeding one time at noon and one time at 6PM. in summer and fall, and feeding once at 12 noon or 5PM. in winter and spring; 5), water changing, namely changing water once every 20 days in winter and fall while once every 50 days in winter and spring; 6), cleaning and disinfection, namely preparing 0.1%. of a potassium permanganate solutionand spraying the same once very 15 days. The breeding method is favorable for artificial breeding of the benthosema pterotum.

Description

technical field [0001] The invention relates to the field of breeding, in particular to a method for breeding seven-star fish. Background technique [0002] The seven-star fish is also known as the point star fish and the flower star fish. The scientific name is the moon snakehead. It is a carnivorous bottom-dwelling fish. It is timid and likes to drill caves. It is resistant to low oxygen and does not hibernate. It can survive the winter safely in the south. It can be cultivated in ponds, pools or fields with water sources, and digging ditches in the ground. Generally, it is advisable to require a bath water depth of 60-80 cm. The fish is sexually mature at two winter ages, spawns and reproduces in March of the lunar calendar, and can be stocked when the seedling body is 3-4 cm long in early April. The seven-star fish is fresh and tender, contains high protein, and is rich in nutrition; at the same time, it has high medicinal value, has the functions of dispelling rheumati...

AI Technical Summary

Problems solved by technology

The seven-star fish is fresh and tender, contains high protein, and is rich in nutrition; at the same time, it has high medicinal value, has the functions of dispelling rheumatism, nourishing blood, and promoting wound healing. , and with the increasing market demand, the wild seven-star fish is far from meeting the needs of the market. How to use the artificial culture of seven-star fish to effectively protect and obtain higher levels has become the main direction of research.
