As for most fish, male and female tilapia look the same. The female lays eggs while the male fertilizes them, and this is a clue about how to tell them apart. Under the fish near the tail, there are several openings that are different in males and in females. This difference is used by fish farmers to identify the male fish, which they prefer because those fish grow bigger. Other differences between males and females are in the internal organs and the behavior after spawning. Tilapia are becoming a very popular food fish and knowing about the male and female fish differences and their reproductive cycle can help everyone appreciate how these interesting fish live.

Male and female tilapia exhibit differences in size, behavior, internal organs and You tube sex trafficking talapia genital openings.

Internally, males have testes that produce sperm while females have ovaries to lay eggs. The males grow You tube sex trafficking talapia than the females and are therefore preferred for fish farming.

To identify male fish, the fish farmer looks for the genital papilla on the under side of the fish, to the rear of the anus You tube sex trafficking talapia before the anal fin. Males have one urogential opening while females have separate openings for urine and for eggs. Once the eggs are laid by the female and fertilized by the male, the female carries the eggs in her mouth until they hatch. Although some fish can change their sex and the differences in the two sexes are less noticeable than for most mammals and birds, fish such as tilapia and pet goldfish are either male or female and their young are born after the fish bring together eggs and sperm.

Some fish lay eggs into open water while the males scatter a large volume of liquid containing sperm in the hope that some of the sperm will reach a few eggs. Others lay eggs in protected places such as hollows in a lake or river bottom and the male can target his sperm better. Still others give birth to live young, with the male using a modified fin to place sperm near the female's oviduct and fertilizing the eggs inside the female.

In each case, the primary difference between male and female fish is related to the sex organs. In tilapia, the female lays the eggs while the male fertilizes them with sperm.

For comparison, look at goldfish. Pet goldfish have a slightly different method of reproduction and fewer differences.

The female lays You tube sex trafficking talapia large number of eggs that tend to stick to water plants while the male produces a large amount of milt, a fluid that contains sperm. Some eggs are fertilized and hatch to produce young fry.

It takes about a year for a goldfish to mature fully. The examples of tilapia and pet goldfish demonstrate how You tube sex trafficking talapia have the male and female sexes and how they rely on eggs fertilized by sperm.

The details of how the fertilization is carried out and how the young are hatched can vary greatly. The main differences between the two sexes are related to the sex organs and the external openings for eggs and sperm.
