Zebrafish breeding methods how to distinguish between male and female zebrafish

When it comes to zebrafish, many people must be familiar with it. Zebrafish is a small tropical fish in the upper layer, and there is room for development in the breeding of this small tropical ornamental fish on the market. But as there are more and more zebrafish on the market, its breeding methods have been put on the agenda. Many novice people don't know much about the reproduction of this kind of fish. Let's learn it together.

Breeding methods of zebrafish

The main results are as follows: 1. The blue stripes of female fish are easy to distinguish between male and female, and the blue stripes of male fish are yellow with lemon stripes between them. Blue and bright, sometimes with silver-gray stripes, the body is fuller and stronger than the male fish, and each fin is shorter than the male fish. Breeding is relatively easy, and the suitable breeding water temperature is 249.

2. The bottom of the breeding box should be covered with small pebbles as a sanctuary for fish eggs. The parent fish enter the box according to the ratio of two females and one male and lay eggs after chasing for about one day. The eggs are non-viscous sunken eggs scattered in the voids of small pebbles.

3. At the end of spawning, the parent fish should be taken out immediately to avoid eating eggs. Each female lays more than 300 eggs at a time, and those with larger size can sometimes produce thousands of eggs. The fertilized eggs hatched for about 36 hours. After 2 days, the yolk sac of the young fish disappeared and could swim and feed.

4. To prevent the fish eggs from being infected by bacteria when hatching, add two drops of 5% methylene blue to the box. The young fish can distinguish between male and female after about 2 months, reach sexual maturity in 5 months, and reproduce 6-8 times a year.

How to distinguish between male and female zebrafish

It is easy to distinguish between various features such as body size. Male zebrafish is slender and has large fins. Compared with the color, the female zebrafish is bright brown with prominent stripes. The female zebrafish is enlarged in size and yellowish in color, especially during pregnancy. Generally speaking, it can be distinguished by body size, body color and the degree of darkness of the stripes. I hope these points will be helpful to you.

How to raise zebrafish

The main results are as follows: 1. The requirement of water quality is not high: the breeding water temperature is 20-23 ℃ and can still survive when the water temperature is 11-15 ℃. The water quality of zebrafish is neutral, but prefer soft water. If soft water is needed during the breeding of the next generation, soft water can improve the fertilization and hatching rate.

2. Fish tank daily feeding: during daily feeding, you can put some pebbles at the bottom of the aquarium to make the water relatively clear. It is best to use a 30m aquarium to raise a fish tank. Because zebrafish is 3-4cm long, it is a relatively small ornamental fish. But the size of the tank depends on the amount of fish raised. The eating habits of zebrafish are quite simple and can be ingested naturally and artificially.

3. Natural artificial bait: the eating habit of zebrafish is quite simple, whether it is natural bait or artificial compound feed can meet its growth needs, zebrafish will also eat.

4. Mixed culture of other species: zebrafish is gentle, 3-4cm, small and exquisite, swimming in the aquarium almost all day long. It is easy to raise and can be mixed with other species of small and mild tropical fish.

5. Age selection of parent fish: zebrafish is an egg-laying fish, 4 months old into the sexual maturity period, generally choose to use 5-month-old fish as parent fish, plus the fish should only be strong and strong, in order to reproduce better.

Disease control of zebrafish

1. Bacterial Gill rot: 0.3 × 10-6 dibromohydantoin can be sprinkled in the cement pool and used again every other day, and special aquarium drugs can be used in the aquarium.

2. Rotifer: infected fish often rub sand or jump dramatically. When diseases and insects are parasitic on the body surface, fish will secrete turbid mucus; when parasitic on the Gill, they will secrete a large amount of mucus and cause difficulty in breathing. Rotifers usually come from eating raw bait with the source of the disease. Therefore, if you feed the red worm, you must disinfect and wash it before feeding. Can be sprinkled with copper sulfate and sulfite mixture 0.5mg/L in the whole pool, and then sprinkled with 0.3mg/L chlorine dioxide the next day. Special aquarium drugs are available in the aquarium.

So much for the breeding method of zebrafish and how to distinguish between male and female. I hope it will be helpful to you. Zebrafish has a high fecundity and can reproduce many times a year, so it is the first choice for beginners.
