How does Loach breed?

Loach, known as "ginseng in the water", lives in the lake pond, is a kind of fish with high nutritional value, it is different from other fish, regardless of appearance, shape, living habits are different, is a special kind of Loach. So, how does Loach reproduce?

1. How to reproduce Loach

The breeding period of Loach varies from region to region. It is usually from April to August, but May to June is the peak spawning period. When spawning, several male Loach chased and entangled a female Loach, and constantly kissed the head and chest of the female Loach with its mouth. Soon, a male Loach wrapped its body around the abdomen of the anus of the female Loach to stimulate the female Loach to lay eggs, and at the same time excreted sperm to complete in vitro fertilization. The eggs will be laid soon and the seedlings can be hatched in 2 or 3 days.

2. Selection and cultivation of parent Loach

(1) the source of parent Loach. It can be caught from rice fields, ponds, ditches, rivers and other waters; it can also be selected from overwintering ponds; or it can be purchased at markets or Loach farms.

(2) the choice of parent Loach. The parent Loach must be an individual with normal figure, normal color, strong physique, disease-free, injury-free and good gonadal development. Specifically, the individual should be larger, the female Loach should have a body length of more than 15cm, a body weight of more than 20g, a dilated abdomen and a flexible abdomen, and a male Loach with a body length of more than 10cm and a body weight of more than 15g. The time of choosing parents of Loach is from March to April in Jiangnan area.

Collected pro-Loach, the physique is not necessarily so ideal. Therefore, it is best after a period of intensive cultivation to make its physique stronger and gonadal development better. After cultivation, the sex cells of the parent Loach can mature rapidly, which will increase the fertilization rate, hatching rate and even the survival rate of larvae.

The area of parent Misgurnus anguillicaudatus culture pond is 60-100m2 and the depth is 1m. 7-10 days before use, 20cm fertile soil should be laid at the bottom of the pool. The whole pond was disinfected with 150 × 200g quicklime per square meter and injected with 40-50cm water. The water injection should be filtered by sieve silk for 40 months to prevent pests from entering the pond and set up a fish fence with barbed wire at the injection and discharge outlet to prevent the Loach from escaping.

When the water temperature is about 18 ℃ at the beginning of May, the selected parent Loach can be transferred to the culture pond for intensive cultivation, and the stocking density is 8-10 tails / m2. During the breeding period, feed animal feed such as minced meat, animal offal or fish meal as far as possible. The daily feed intake can account for 3%-5% of the total body weight of the parent Loach, supplemented with a small amount of plant feed such as rice bran, wheat bran and fresh aquatic plants. Since Loach is foraging at night, the feeding time should be in the evening. Replace the fresh water every 2-3 days, and each time the pool water is changed at the rate of 1 beat 4 times 1 pm 3 degrees.
