ginseng fish
Generally, ginseng fish are divided into freshwater ginseng fish and seawater ginseng fish. Since there are differences, there will naturally be differences in breeding. The second season of spring and autumn is the growth period of freshwater gallfish. It can be grown artificially or naturally. However, most of them are currently grown artificially. Let’s talk about freshwater fish. Pay attention to the growth of fish.
1. Ovoviviparous fish
Peacock, swordtail fish, moon fish, Mary fish, etc. The female fish is fertilized internally, and the fertilized eggs will develop and mature in the female fish's abdomen and directly give birth to larvae. The larvae will swim when they encounter water.
2. Fish that feed on aquatic plants and pebbles
Fish that use aquatic plants or pebbles as nests to lay eggs mainly include Cyprinidae and Cyprinidae. The water used for growth is mostly weakly acidic soft water, with aquatic plants planted in the four corners and some pebbles scattered at the bottom of the tank.
3. Foam-egg-laying fish
Most of the family Silkfoot (rare pearl vests, Lili, fighting fish, warships, etc.) are foam-egg-laying fish. If there are a few floating aquatic plants or green vegetable leaves floating on the water, the male fish will spit out a lot of foam on the aquatic plants or the corners of the fish tank. After the female fish lays eggs, the male fish will hold the fertilized eggs in his mouth and spit them into the foam. The male fish is very protective of eggs and will take care of them until the larvae hatch.
4. Fish that lay eggs on magnetic plates
Most of them are giant fish. Under natural circumstances, broodstock will lay eggs on the leaves of broad-leaf aquatic plants, so green plastic boards or ceramic tiles are used as nests in the aquarium instead.
5. Rock-laying fish
Some complex species, such as maps, pineapples, etc., mostly use smooth rocks or marbles as nests when they grow.
6. Oviparous fish in flower pots
Mainly cichlids, such as colorful phoenix, etc. Like to scatter eggs on the inner wall of the flower pot. In addition, the colorful giants also use flower pots to lay eggs, but they like to lay their eggs on the outer walls of the flower pots.
7. Mouth-hatching ovipositing fish
Hatching-egg-laying fish are very rare among tropical freshwater fishes. The only mouth-hatching silverfish found in the Amazon River Basin and South America Guyana's silverback, African crucian carp (tilapia) in Africa and Egypt, most African cichlids (Sanhu, Ruby, Shijian, etc.) and various arowanas. There are many seawater fish hatched in the mouth, such as sea bream, etc.
In this fish, the male digs the nest by himself, and the female stays on the left and right. After digging the nest, the male induces the female to enter the nest to lay eggs. The male fish ejaculates along with it. The female fish lays eggs while fertilizing them. It is put into the hatching sac in the mouth, and the fertilized eggs take 7 to 8 days toThe larvae hatch into larvae. The female fish will not spit out the larvae until the larvae have absorbed the yolk. The larvae will swim closely next to the female fish in search of food. If the female fish is slightly hurt, she will quickly take the larvae into her mouth again and swim away. Oral-brooded fish have a strong maternal instinct, so although the number of eggs they lay is smaller, the survival rate of the larvae is higher.
8. Growth water
Activated carbon filtered water: Put activated carbon into a plastic or enamel drum, let tap water flow in from the water inlet at the bottom and flow out from the water outlet at the top . The filtered water is stored in an aquarium or other container, and can be used as water for daily breeding and growth of common tropical fish.
Ion-connecting resin water filtration: Ion-connecting resin is used as filter material, and with the help of the adsorption capacity of anionic and cationic connecting resin, calcium ions, magnesium ions, and nitrite in the water can be adsorbed. The filtered water quality is neutral soft water, suitable for the growth of fish of the family Carpidae, Cyprinidae, and Cyprinidae.
Deionized water: also known as distilled water. Electrodialysis and electrolysis are widely used to obtain the water quality, which is very pure. The quality of deionized water is extremely soft and the oxygen content in the water is extremely low, making it unsuitable for feeding. When used, it is often mixed with dry clean water to obtain water quality with different hardness and pH to meet the water needs of different types of growth.
Rainwater: The water quality is soft and contains very little metal ions. It is suitable for the growth of carps and carps. Generally, it can be used in places with fresh air in suburban areas. Rain and precipitation can be collected in containers and then filtered before use.
There are many types of freshwater ginseng fish. When breeding and growing, the most taboo is blind mixed culture. Breeders must understand which freshwater ginseng fish are suitable before growing them. It doesn't matter what you grow in a mixed way, and you think your growth is frustrated.
