影响金鱼产卵的常见因素

金鱼（详细介绍）

金鱼的产卵时间一般在繁殖季节的早晨4-5点到10点。然而，成熟的亲鱼有时会在晚上5-6点换成淡水后产卵，少数鱼也会在夜间产卵。至于金鱼的繁殖数量，繁殖的第一阶段是在春季，这一阶段的产卵数量因金鱼的品种、年龄、体质和气候而略有不同。每条成熟的雌性金鱼可以产卵2-3次，最多4-6次。在正常情况下，每次产卵的间隔约为10天。如果亲鱼较弱，则间隔时间较长。条件较好的金鱼养殖场可以在秋季的第二阶段繁殖。然而，秋季繁殖的鱼苗生长发育不如春季繁殖的鱼。金鱼产卵的数量也与金鱼种类、年龄、体格、饲养管理和气候因素有关。通常，一条强壮而成熟的雌鱼会少生数千个卵，多生数万个卵。通常，2-3年内母鱼的产卵次数和产卵量最多。它们的受精率和孵化率都很高，遗传特征也很明显。同时，一些2-3岁的雌性金鱼在春季产卵后仍能在秋季产卵，尤其是一些产卵量不多或春季不产卵的雌性金鱼更容易在秋季产卵。此外，由于体质虚弱，亲鱼在春季没有产卵。后来，当它们恢复正常并得到适当喂养后，它们可能会转移到秋季发情并产卵

Common factors affecting goldfish spawning

goldfish (detailed introduction)

The spawning time of goldfish is generally 4-5 to 10 o'clock in the morning during the breeding season. However, mature parent fish sometimes spawn after changing into fresh water at 5-6 p.m., and a few fish also spawn at night. As for the number of goldfish breeding, the first stage of breeding is in spring, and the number of spawning in this stage varies slightly due to the variety, age, constitution and climate of goldfish. Each mature female goldfish can lay eggs 2-3 times, up to 4-6 times. Under normal circumstances, the interval between each spawning is about 10 days. If the parent fish is weak, the interval is longer. Goldfish farms with better conditions can breed in the second stage in autumn. However, the growth and development of fry bred in autumn is not as good as that of fry bred in spring. The number of goldfish spawning is also related to goldfish species, age, physique, feeding management and climate factors. Usually, a strong and mature female fish spawns thousands of eggs less and tens of thousands more. Usually, the number of spawning times and amount of spawning of parent fish in 2-3 years are the most. Their fertilization rate and hatching rate are high, and their genetic characteristics are also obvious. At the same time, some 2-3 year-old female goldfish can still spawn in autumn after spawning in spring, especially some female goldfish that do not spawn much or do not spawn in spring are more likely to spawn in autumn. In addition, the parent fish did not lay eggs in spring because of their weak constitution. Later, when they recovered and were properly fed, they might move to autumn to estrus and lay eggs
