【Introduction】Loach (Misgurnus anguillicaudatus), belongs to the family Cobitidae. Loach is called "ginseng in the water". It is distributed in all parts of southern China. It is not common in the north but is also distributed everywhere. It can be harvested all year round, and is most abundant in summer. After being caught, loach can be used fresh or dried. Loach lives in lakes and ponds, and is small in size, only three or four inches long. It has a round body, a short body, small scales under the skin, a dark blue color, and is covered with its own mucus, making it slippery and difficult to hold. It is a fish with high nutritional value. It is different from other fish in appearance, body shape, and living habits. It is a special loach. The body is slender, and the front section is slightly cylindrical. The back is flattened, the abdomen is round, the head is small, the mouth is small, and it is horseshoe-shaped. The eyes are small, and there are no spines under the eyes. There are 5 pairs of whiskers. The scales are extremely small, round, and buried under the skin. The back and sides of the body are gray-black, with many small black spots all over the body, and there are also many black spots on the head and fins. The spots on the dorsal and caudal fin membranes are arranged in rows, and there is a distinct black spot at the base of the caudal peduncle. The other fins are gray-white. Loaches are widely distributed in China, Japan, North Korea, Russia, and India along the coast of Asia. They are edible and used as medicine.

【Cultivation conditions】

Loach is a multi-spawning fish. Under natural conditions, it starts to reproduce in early April, with the peak spawning period from May to June, and can continue to spawn until September. The water temperature for reproduction is 18-30℃, and the optimal water temperature is 22-28℃.

Female loaches reach sexual maturity later than male loaches. When they are 5 cm long, they have a pair of egg nests in their bodies. When they are 8 cm long, the two ovaries fuse together to become one ovary, extending from the front to the back. At this time, the entire ovary begins to mature.

The number of eggs carried by female loaches varies greatly depending on the size of the individual. The smallest sexually mature individual is 8 cm long and carries about 2,000 eggs. The 10 cm long individual carries 7,000 to 10,000 eggs. The 12 cm long individual carries 12,000 to 14,000 eggs. The 15 cm long individual carries 15,000 to 18,000 eggs. The 20 cm long individual carries about 24,000 eggs. The largest number of eggs can exceed 65,000 eggs. The eggs are oval in shape, with a diameter of about 0.8 to 1.0 mm. After absorbing water, they swell to 1.3 to 1.5 mm. They are yolk in color, semi-sticky, and have weak adhesion. Because the eggs are not mature in the ovary at the same time, the number of eggs ovulated each time is about 50% to 60% of the number of eggs carried.

The minimum sexually mature male loach is more than 6 cm long, and sexual maturity is earlier than that of female loach. Male loach has a pair of testes, located on both sides of the abdominal cavity, in a banded and asymmetrical shape. The testes on the right are longer and narrower than those on the left, and are also lighter. When the male loach is 9-11 cm long, there are about 100 million sperms in the testes. Loach prefers to lay rock eggs in the morning after rain. Before laying eggs, the female loach swims in front, and several male loaches chase closely behind. When in estrus, male and female loaches mostly move on the water surface and around the fish nest. When the estrus reaches a climax, the heads and bodies of the male and female loaches rub against each other and swim out of the water one after another. The male loach chases and entangles the female loach, and curls around the female loach's abdomen to stimulate the female loach to lay eggs. At the same time, the male loach also discharges sperm for in vitro fertilization. The number of times this action occurs varies depending on the size of the individual. A large individual may do this more than 10 times. The fertilized eggs first adhere to aquatic plants or other attachments, and as the water fluctuates, they easily fall off the attachments and sink to the bottom of the water.
