How do fish reproduce?

The way fish reproduce varies depending on the species of fish. Some fish are oviparous, meaning they reproduce by laying eggs; others are viviparous, meaning they hatch eggs and give birth to young after they hatch inside their bodies. The following is a brief introduction to common fish reproduction methods in general:

Reproduction of oviparous fish:

Egg laying and fertilization:

Oviparous fish usually choose a suitable reproductive site. The female fish lays eggs in a suitable environment, and then the male fish releases sperm for fertilization.

incubation:

The eggs that are laid live in a specific environment and require suitable water temperature and quality during incubation. The hatching time of different species of fish eggs will vary.

Care of juvenile fish:

Some oviparous fish will continue to guard and care for their eggs and young after spawning, while others will leave their eggs to hatch naturally in environments such as streams.

Reproduction of viviparous fish:

incubation:

The eggs of viviparous fish hatch into young fish inside the body of the female fish. When the young fish mature, they reproduce by giving birth to young fish.

Whether oviparous or viviparous, fish reproduction requires suitable environmental conditions, feeding management and feed supply. For the aquaculture industry, artificial breeding is being widely used to meet the needs of the breeding industry and pet market. During the entire breeding process, special attention needs to be paid to factors such as water quality, water temperature, and reasonable feed supply to provide the most suitable environmental conditions to promote fish reproduction.
