Fish Breeding

by mouth

Induced breeding is an optimal effort to produce fish fry without considering the season. This technique is used to produce fry of fish species that have or potentially have great economic significance for aquaculture, which do not reproduces spontaneously in captivity.

some times like a guppy and mollie or sowrd tail and platy

Becoming an ichthyologist offers the advantage of engaging in fascinating research about fish species, contributing to biodiversity conservation, and enhancing our understanding of aquatic ecosystems. It can also provide opportunities for fieldwork, travel, and collaboration with other scientists. However, disadvantages may include limited job opportunities, often requiring advanced degrees, and potential challenges in securing funding for research projects. Additionally, working in remote locations and dealing with environmental regulations can be demanding.

Goldfish don't always stay the same color. As a goldfish ages, it can turn a variety of colors, like orange or yellow or white, including patches or spots of color as well.
Common household goldfish tend to change colors throughout their lives. White, orange, and yellow color changes, in whole or in part, are very common.

Nope, that can not happen.

Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.

The female seahorse deposits her eggs into an opening in the front of the male's body, and he keeps them into a pouch until they hatch, at which time they "squirt" out of him. The seahorse is not pregnant in the sense we think of pregancy, he is just carrying the eggs in a safe place in a specialised pouch for doing so.

Fascinating. But the many different species behave differently and have different methods of courting and spawning and fertilising the ova.

They will spawn when conditions are right. There is nothing you can do to stop them other than making them all too sick to spawn.

around 20+

Because that is where they are most comfortable spawning the next generation.

it differs from one type to another for eg carp takes about 5 years

pacu takes about 7-6 years

gold fish 4-5 years

cat fish 8-7 years

tilapia 1-2 years

giant gourami 4-5 years

............................and so on

Not only does it depend on the species like it says above, it also depends on many other factors. If you are talking about raising fry in an aquarium, there are several major factors to consider. How much and what types of food are fed, the temperature of the tank, the general water quality and the size of the tank to name the most important factors.

Generally speaking most aquarium fish will reach adulthood (sexual maturity) in less than 6 months time. Ther are of course exceptions. Some can mature in as little as 60 days, others in over a year and in some cases we really don't know since no one has ever bred them in captivity.

by nose

They breed, (Give Birth) to another fish a few days after mating, but be careful because the fish eggs are small and may be eaten by fish. (Not Sure answer but is close)

In guppy populations, it's common for adult guppies to eat their own offspring, especially if they are stressed or hungry. The number of baby guppies consumed can vary widely, depending on factors such as the size of the adult population, availability of food, and environmental conditions. Generally, it is estimated that a significant portion of the fry may be eaten, especially in the absence of cover or hiding places. Providing plenty of vegetation and hiding spots can help reduce predation among guppies.

U need a really big tank and A LOT of live food. They can be pellet raised but it is better to feed them what they are meant to eat and that is smaller fish then itself. They are also aggressive fish. You need to take into consideration that these fish grow up to 7 feet long maximum which means your pretty much going to need a tank the size of a small backyard eventually if your going to keep it for its whole lifespan. Otherwise it needs to go back to its natural habitat. No not your local lake or the closest one nearby. You actually need to go to a place that has alligator gars inhabiting the body of water if you plan on releasing it. Also wear gloves if you plan on handling the gar as the roe of the gar can be poisonous and they have extremely sharp scales. I would not recommend raising an alligator gar but that is totally your decision. I would consider getting a Florida or spotted gar instead because they look more like a aquarium fish as they have very nice looking spots along their body. Alligator gars require a lot of care and attention so be wise when make a decision if you plan on getting one.

if you're refferring them to being young then no
