When do loaches lay eggs and when do loaches lay eggs

Loaches are multi-spawning fish. Under natural conditions, breeding begins in early April, and the spawning season is from May to June, and it continues until September when it can also lay eggs. The water temperature for breeding is 18-30, and the optimal water temperature is 22-28

When the female loach matures later than the male loach, when the body length is 5 cm, the female loach has a pair of ovaries in the body, and when the body length is 8 cm, the two ovaries heal together to become one ovarie, and extend from the front end to the back end, at which time the whole ovary begins to mature.

The amount of eggs carried by female loaches varies greatly depending on the size of the individual. The smallest sexually mature individual has a body length of 8 cm and a pregnancy of about 2 000 eggs, a 10 cm egg pregnancy of 7000-100 00 eggs, a body length of 12 cm of 12 cm of eggs 12000-14000, a body length of 15 cm of 15 cm of 18000 eggs, and a body length of 20 cm of about 24000 eggs. The maximum number of eggs can exceed 10,000.

Oval, about one millimeter in diameter, swells to one millimeter after water absorption, egg yellow, semi-viscous, and the adhesion is not strong. Due to the inconsistent maturity of eggs in the ovaries, the amount of ovulation per ovulation is about 50% to 60% of the number of eggs conceived.

It will take millions of years to evolve into a snake and give birth.

Under natural conditions, the spawning season begins in early April, and the spawning season lasts from May to June, and the spawning season lasts until September. The water temperature for breeding is 18 to 30 degrees Celsius, and the optimal water temperature is 22 to 28 degrees Celsius.

Female loach sexual maturity is later than male loach, when the body length is 5 cm, the female loach has a pair of ovaries in the body, when the body length is 8 cm, the two ovaries heal together, become one ovarie, and extend from the front end to the back end, then the whole ovary development 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 the number of eggs is about 2,000 in the 10 cm type, 12,000 to 14,000 eggs in the 12 cm length, 15,000 to 18,000 eggs in the 15 cm length, and about 24,000 eggs in 20 cm in length. The maximum number of eggs can exceed 10,000.

Oval, the diameter of the egg is about millimeter, it swells to millimeter after absorbing water, the egg is yellow, semi-viscous, and the adhesion is not strong. Because eggs do not mature at the same level within the ovaries, each ovulation is about 50 to 60 percent of the number of eggs conceived.

<> loaches generally start to breed in spring (early April) under natural conditions, and the peak spawning season is from May to June, and it can also spawn in autumn (around September). The water temperature for breeding is 18-30 and the most suitable water temperature is 22-28.

Loaches do not give birth to baby loaches, but they do lay eggs, which then hatch into small loaches. Loach is known as ginseng in the water, lives in lakes and ponds, is a kind of fish with high nutritional value, it is different from other fish, no matter the appearance, body shape, living habits are different, it is a special loach.

The amount of eggs carried by female loaches varies greatly depending on the size of the individual. The smallest sexually mature individual has a body length of 8 cm and a pregnancy of about 2,000 eggs, a 10 cm pregnancy of 7,000-10,000 eggs, a body length of 12 cm of 12,000 eggs, a body length of 15 cm of 15,000 to 18,000 eggs, and a body length of 20 cm of about 24,000 eggs. The maximum number of eggs can exceed 10,000.

The egg is round, the diameter of the egg is about one millimeter, and it swells to one millimeter after absorbing water, and the egg is yellow, which is semi-viscous and not strong. Due to the inconsistent maturity of eggs in the ovaries, the amount of ovulation per ovulation is about 50% to 60% of the number of eggs conceived.

1. The incubation water contains water mold, and the disinfection work before incubation is not thorough. 2. The choice of disinfectant is wrong, water mold is a fungus, and it is impossible to kill water mold with general bacteria-killing disinfectants. 3. The low fertilization rate of fish eggs leads to death, which is very easy to be infected with water mold, and quickly spreads to infect the surrounding normal fish eggs.

4. The dissolved oxygen in the water body is insufficient, resulting in the lack of oxygen and death of the fish eggs during the incubation process, and the infection of water mold. 5. The water quality is not good. 6. The water temperature is too low, which increases the time for mildew infection in water.

Loach breeding begins in early April, and the spawning season is from May to June, and it continues to spawn in September. The water temperature for breeding is 18-30, and the optimal water temperature is 22-28

The artificial propagation, seedling cultivation and cultivation technology of loach are carried out in the cement pool, with an area of 5 square meters, the depth of the pool is meters, the depth of the water is meters, the water is the exposed well water, and the water temperature is controlled at 23-25. Ovaries are set in the spawning pool, made of brown bark or aquatic plants boiled in boiling water, and the ovaries are fixed on the ** of the spawning pool with a bamboo pole. Oxytocic drugs are used with chorionic stimulation (HCG), 1000 IU per female loach, and the dose is halved for male loaches.

The amount of liquid medicine injected is milliliters.

After the artificial reproduction technology of loach is in spring, the fish pond is trimmed, and new water is injected after disinfection with quicklime, and after the medicinal properties of the pond water disappear, the broodstock is put into the pool according to the ratio of male and female 1:2, and about 300 grams per square meter of area.

When the water temperature rises to about 20, a fish nest made of brown flakes, willow fibrous roots or aquatic weeds is placed in the pool. After placing the fish nest, it is necessary to check and wash the mud and dust on it frequently, so as not to affect the adhesion of the eggs when the loaches spawn.

Spawning from April to September. Anhui Haina Baichuan Ginseng Farm, with a base area of 3,000 acres, Manager Liu**150, the middle four 5570, and the last four 8395 are connected together and do not let the hair. The QQ number is (6 digits), the first three 2s, and the last three digits are 503.
