Fish reproduce through oviparous methods, partly in vitro fertilization and partly in vivo fertilization. Female fish that are fertilized in the body will lay eggs out of the body to hatch, and some hatch in the body. The small fish produced in this way are called ovoviviparous. Generally, fish raised at home need to be hatched, and a special breeding tank should be prepared, and the fish should be placed in it. After the fish mate successfully and spawn, the eggs will hatch and grow into small fish.
How do fish reproduce?
First, the mode of reproduction
There are many species of fish, and they reproduce mainly in an oviparous way. Most of the cartilaginous fishes are fertilized in vivo, and there are two types: oviparous and ovoviviparous. The bony fishes are fertilized in vitro, most of which are oviparous, and a few have undergone abnormal development. Generally, during reproduction, the fish will eliminate the eggs after mating and will hatch after a period of time. There is also a part of it after hatching in the body, the larvae are excreted.
Second, Domestic fish reproduction
1. Prepare to breed
When the fish raised at home are preparing to breed, prepare a special breeding tank or breeding pond in advance. This is to ensure that the fish are not disturbed by other fish when they lay eggs and to ensure the safety of the broodstock and fish eggs. According to common sense, the temperature of the breeding pond and the breeding tank should be slightly higher than the normal water temperature, which is conducive to helping the spawning and hatching of fish eggs.
2. Matching Broodstock
After the breeding site is ready, put a certain proportion of male and female broodstock in it. The time point of fish reproduction is usually in the evening or night. Therefore, it is necessary to observe and pay attention. After the reproduction is completed, the broodstock must be taken out in time to prevent the female fish from swallowing the eggs. The broodstock that has just been fished cannot be put back into the original aquarium immediately, otherwise, it will be attacked by other fish. You should raise it alone for a while and wait until it recovers before putting it back into the original aquarium.
Third, Raising young fish
The spawning time of different types of fish eggs will also be very different. On the first day of hatching, there is no need to feed them, and they can continue to consume the yolk sac. On the second day, you can properly give them some fish feed suitable for them. Small fish larvae can be fed with water, and larger fish can be fed with small fish and insects.
Most fish reproduce in twins. When fertilized eggs are produced, the eggs must adhere to the object, otherwise, they will sink to the bottom of the water due to gravity, which will affect the hatching effect. If the fish eggs sink to the fish pond or the bottom of the fish tank, they will die due to gravitational backlog or be buried by dirt, so it is particularly important to choose a good fish egg spawning brush.
In the past, traditional artificial fish nests were composed of grassroots or aquatic plants, and they had to be treated well before use, otherwise, the mold on it would harm the fish eggs. This kind of natural plant is complicated to make, the material used is unstable, and it is difficult to guarantee that it will not rot in the water. The egg spawning brush is made by imitating aquatic plants, which can provide a more natural production environment for the spawning period and is more conducive to the spawning of female fish.
Fish Egg Spawning Brush
Traditional artificial fish nests are made of aquatic plants or grassroots and need to be treated before use, otherwise, the mold attached to them will damage the fish eggs. However, the processing methods of these natural plants are more complicated, and the materials are also unstable, and it is difficult to guarantee that they will not rot in the water. The egg spawning brush is made of imitating aquatic plants, which can provide a more natural production environment for the fish during the spawning period, and is more conducive to the spawning of the female fish.
Modern society emphasizes efficiency and technology. Improving technology and increasing output are people's goals. Optimizing production tools is one way. AOQUN Fish Egg Spawning Brush is light in weight, easy to clean, durable, and will not be blocked even if it is not cleaned for a long time. Its adhesive function is extremely strong, which can improve the success rate of fish egg spawning.
