Problems solved by technology

Loach is an omnivorous animal. It mainly eats animal feed when it is young, and can eat some algae and plant roots and stems after adulthood. In addition to respiration with gills, loach can also perform skin respiration and intestinal respiration. However, in summer, if The water quality is not well controlled, and the breeding density of loach is too high, which will still cause a large number of loach to suffocate and die

Embodiment Construction

[0010] Drain the water in the earth pond of the previous season, sprinkle 100~120kg of quicklime per mu, inject water after 2~3 days of light, start topdressing fertilizer 4~6 days before seedlings, and throw 120~145kg of livestock manure per mu to make the pool transparency at 20 ~30cm, and then put in loach summer flowers, the stocking density is 50-80 tails per square meter. The feeding amount is 1-3% of the body weight of the loach, and the feeding amount is increased as the temperature rises; the water is changed once a week in spring and autumn, and the water is changed every 2-4 days in summer, and the amount of each water change is 1 / 3 of the total water amount ~2 / 3. Loach summer flowers are soaked in salt water before feeding to prevent saprolegniasis, and at the same time, it can enhance the resistance of loach to pathogens. From June, when the temperature is higher than 25 degrees Celsius, 2 to 3 aerators per mu of ponds are guaranteed to operate. Sprinkle photosy...

Abstract

The invention discloses a pond culture method of loaches, belonging to the field of aquiculture. The method comprises the following steps of: draining all water in an earthen pond in the last quarter, splashing quicklime, performing light illumination for 2-3 days, then injecting water, starting to dress a fertilizer, then releasing seedlings for 4-6 days, putting in 120-145kg of animal manure per mu, enabling the transparency of a water pond to be 20-30cm, and then putting in larvae of the loaches, wherein the larvae are immersed in 2-3% common salt water before the larvae are put in; and starting to put baits in the earthen pond when the water temperature is higher than 15 DEG C, wherein the feeding amount per day is 1-3% of the body weight of the loaches and the feeding amount is increased along with the increase of the air temperature, the water is changed once every week in spring and autumn, the water is changed once every 2-4 days in summer, and the water change amount every time accounts for 1 / 3-2 / 3 of the total water amount. The larvae of the loaches are immersed in the common salt water before putting in so as to prevent saprolegniasis and simultaneously enhance the resistance of the loaches to pathogenic bacteria. According to the pond culture method disclosed by the invention, the survival rate of the loaches in summer is significantly improved, the oxygen content in the water is ensured, and the yield of the loaches is improved. The pond culture method disclosed by the invention is particularly suitable for higher-density culture of the loaches.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating loach in a pond. Background technique [0002] Loach is a fish with high nutritional value. It is small and slender. It is distributed in rivers, ditches, ponds, paddy fields, lakes, and reservoirs across the country. It is a small-scale freshwater economic fish. Loach is an omnivorous animal. It mainly eats animal feed when it is young, and can eat some algae and plant roots and stems after adulthood. In addition to respiration with gills, loach can also perform skin respiration and intestinal respiration. However, in summer, if The water quality is not well controlled, and the breeding density of loach is too high, which will still cause a large number of loach to suffocate and die. Contents of the invention [0003] Purpose of the invention: the purpose of this invention is to provide a method for large-scale cultivation of loach ponds that improve the su...
