Nearly all fish reproduce sexually, and most species have separate sexes. Those without separate sexes avoid self-fertilization by producing sperm and eggs at different times. Each fish typically produces a large number of gametes.

Do fishes reproduce asexually?
Reproduction in Fishes. Nearly all fish reproduce by sexual reproduction – the fusion of sperm produced from testes and eggs produced from ovaries. Most species have separate female and male sexes, but there are also many species that are hermaphrodites, meaning that an individual has both testes and ovaries.
Where do fish reproduce?
The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants.
How do fish reproduce?
In most cases, the female drops eggs in the water which are immediately fertilized by sperm from the male. Another way is for fertilization to occur within the females body before she drops them into the water. With the third and final method, the female retains the eggs within her body and the young are born alive.

Are fish male or female?
You can determine the sex of your fish by inspecting its gonads (reproductive organs), which are located towards the top of the gut cavity. Mature female fish will have orange ovaries and male fish will have white testes (see photos above).
What is fish reproduction called?
Spawning. In many species of fish, a large group of adults come together to release their gametes into the water at the same time. This is called spawning.
How do fish reproduce short answer?
Wild fish reproduce in various ways depending on the species of fish. In most cases, the females release eggs into the water and they are immediately fertilized by sperm from the male. In the wild, fish can easily reproduce when they sexually mature.
Do fishes have periods?
Fish do not have periods. They have internal sexual organs and ovaries that produce unfertilized eggs once a year. When the eggs have matured, the female will eject them into the water for external fertilization by the male. This process, called spawning, makes a menstrual cycle in fish unnecessary.
Do fishes have uterus?
In some species the young develop inside a uterus. Even some species of bony fish like guppies do it, having adapted their anal fin to deliver sperm, although the eggs are then laid rather than developing inside a womb. “It happened 13 different times within teleost fishes.
How do Livebearers mate?
Live Bearers
Fish reproduce by bearing live young or by laying eggs. Livebearers give birth to fully formed and functional young called fry. The eggs are fertilized and hatch within the female.
How do fishes poop?
So, how do fish expel their feces? Well most of them will expel their feces through an anal vent (also called a cloaca), which is simply an opening for all wastes to leave the body. This includes not only feces but also urine, reproduction, and sometimes eggs or sperm if needed.
How does a male fish fertilize eggs?
In livebearers, both the fertilization and development of the babies happens inside their mother. The female carries the eggs inside her body. The male uses his modified anal fin (gonopodium) to deposit sperm into the female’s body.
How do goldfish mate?
Goldfish mate by chasing each other until the female goldfish releases her eggs. The male goldfish then releases his “milt”, which fertilizes the eggs. What is this? Assuming the eggs don’t get eaten, baby goldfish will hatch around a week later.
How do you know when fish are mating?
Signs that your goldfish are ready to mate include white spots along the gills of the males, and the female will become fatter and more rounded. The male will then chase the female around the tank to encourage her to release her eggs.
Can fish be both sexes?
Around 21 families of fish are natural hermaphrodites. These unique hermaphroditic vertebrates include snook, clown fish, wrasse, angelfish, grouper, goby, parrot fish, sea bass and anthias. Synchronous fish, hermaphrodites that are male and female the same time, are much less common than sequential hermaphrodites.
Can fish change sexes?
Researchers have identified more than 500 fish species that regularly change sex as adults. Clown fish begin life as males, then change into females, and kobudai do the opposite. Some species, including gobies, can change sex back and forth. The transformation may be triggered by age, size, or social status.
Do fishes pee?
Yes they do! But why? Well, like most living things, fish too produce waste from their metabolic processes. Peeing is one way of doing that and is referred to as excretion.
Does a catfish have menstruation?
Catfish do not have periods. Like all other fish species, catfish lay eggs once a year during the spawning season. The eggs grow in the female’s belly until they are released for external fertilization by the male. This natural and repetitive process makes a menstrual cycle in catfish completely unnecessary.
Can sharks smell my period?
A shark’s sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids. However, there is no positive evidence that menstruation is a factor in shark attacks.
Do dogs get periods?
Dogs typically go into heat on average every six months, but this varies especially in the beginning. It can take some dogs around 18 to 24 months to develop a regular cycle. Small dogs usually go into heat more often — as much as three to four times a year.
Do goats clitoris?
majora is homologous to the scrotum in males, and it is the visible external portion of the female tract. The clitoris is located in the lower portion of the vulva. It is the excitatory organ of a doe’s reproductive tract.
What is the mother fish called?
What is a female fish called? A female fish does not have a specific name, male and female fish are both just called fish. However, around 500 species of fish are able to change their gender during their later life after birth. A species of fish that can change its gender is called a hermaphrodite.
Do fish only mate with the same breed?
Right. Fish will mate with a species outside their own if the male’s coloring is attractive enough or if the female can’t see him properly, according to new research.
Do fishes kiss?
Kissing gouramis are also popular with aquarists for the fish’s peculiar “kissing” behavior of other fish, plants, and other objects. Kissers of both sexes will often spar by meeting mouths and pushing each other through the water.
Are my goldfish trying to mate?
https://www.youtube.com/watch?v=Z3Qv9Bt52w0
Are goldfish asexual?
Most goldfish breed in captivity, particularly in pond settings. Breeding usually happens after a significant temperature change, often in spring. Males chase gravid female goldfish (females carrying eggs), and prompt them to release their eggs by bumping and nudging them.
Do fishes fart?
Biologists have linked a mysterious, underwater farting sound to bubbles coming out of a herring’s anus. No fish had been known to emit sound from its anus nor to be capable of producing such a high-pitched noise.
Do fish have Buttholes?
It’s a cloaca, but functionally, it’s mostly an anus. But eggs are coming out of that hole too. Everything comes out of there. So having [its anus] right behind the head allows the eggs to get more simply into the gills, which is where these guys brood their young.
Do fish get thirsty?
They don’t ever get thirsty. Marine fish are what’s called hypertonic to the seawater. So essentially, they lose water through their gills to the seawater. The seawater is saltier than their blood.
Do goldfish eat their babies?
A goldfish will likely eat their babies because they end up producing hundreds of eggs when they mate. Goldfish don’t have any paternal instincts, so they don’t recognize their babies. This means they may eat their babies if they are in the same tank.
How long is a fish pregnant?
As examples, the female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.
Can human sperm fertilize fish eggs?
Probably not. Ethical considerations preclude definitive research on the subject, but it’s safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Can fish have babies without a mate?
The small fish species, who is native to the border region of Texas and Mexico, does not produce any male offspring. The females reproduce asexually through gynogenesis, making their daughters identical clones of themselves.
How do fish act when giving birth?

Are my fish mating or fighting?
There will be visible signs if a fish has been attacked in the tank. Such signs include marks on its body and nips on its fins. A fish that is injured will shy away from the other fish to give itself time to heal. Territorial fish are likely to be aggressive toward fish of their own species that are of the same sex.
Are fish non binary?
Many species of fish, like the kobudai, are known as “sequential hermaphrodites”: they can switch sex permanently at a specific point in their lives. The majority of “sequential hermaphrodites” are known as “protogynous” (Greek for “female first”): they switch from female to male.
What fish can change sexes?
Clownfish, wrasses, moray eels, gobies and other fish species are known to change sex, including reproductive functions. A school of clownfish is always built into a hierarchy with a female fish at the top. When she dies, the most dominant male changes sex and takes her place.
What animals are intersex?
The term intersex typically applies to abnormal members of gonochoric species that are usually sterile. It is not to be confused with the term hermaphrodite. Intersexuality has been reported in mammals, fishes, nematodes, and crustaceans.
How can you tell if a fish is pregnant?
As your female fish becomes pregnant, she will grow a bulge at the back of her abdomen. This typically appears over the course of 20-40 days. Does your fish have a red or black spot? Sometimes, when a female fish is pregnant, she will develop a “gravid spot” on the abdomen.
Can you drown a fish?
Because oxygen levels in the water aren’t anywhere close to what they are in the air, fish need to move a lot of water to stay alive. The large surface area of the gills helps them collect as much oxygen as possible. If they’re unable to do this, they can drown (although we know it’s technically more like suffocating).
Do fishes cry?
As we mentioned before, fish cannot cry because they lack the part of the brain which allows mammals to produce tears. This part of the brain is called the cerebral cortex. Besides, fish lack both the emotional depth and mental complexity to be able to cry.
Is Sand really fish poop?
The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.
What animals have periods?
Beyond primates, it is known only in bats, the elephant shrew, and the spiny mouse species Acomys cahirinus. Females of other species of placental mammal undergo estrous cycles, in which the endometrium is completely reabsorbed by the animal (covert menstruation) at the end of its reproductive cycle.
Why are sharks afraid of dolphins?

Does human urine attract sharks?
No reaction. From a scientific standpoint, Esbaugh says that it’s “definitely not true” that sharks are attracted to urine, and he assumes the rumor got started because many animals use scent to track their prey. But he says this doesn’t hold up because humans aren’t the most common meal for sharks.
Can my dog get pregnant while bleeding?
A dog’s cycle consists of four distinct stages, but she can only get pregnant during the estrus period. Her entire heat cycle lasts between two and three weeks.
Do dogs fart?
While the occasional gaseous emission from your pooch is a normal and unavoidable part of life, excessive gas is not. There are several causes of dog farts, from gastrointestinal issues to food intolerance, so you’ll need to visit your veterinarian to determine what’s triggering your dog’s smelly gas.
Why do female dogs bleed?
Vulvar swelling is the first physical indication of an impending heat cycle. However, the most obvious recognizable sign of heat in dogs is vaginal bleeding. This may not become apparent until a few days after the female has come into estrus.
Do monkeys have periods?
Apart from humans, menstruation has only been observed in other primates, e.g. Old World Monkeys and apes (inhabiting mainly Africa and Asia), 3-5 species of bats, and the elephant shrew.
Do chickens have periods?
Here are the deets: Female chickens have a menstrual cycle that can be daily during certain times of the year. Like women, hens have ovaries. During a hen’s cycle, an ovary sends a yolk on its path. The yolk forms what we know of as an “egg white” as it moves through the reproductive tract into the shell gland.
Are all catfish female?
While 68 percent of catfish in the ordinary water were female, 96 percent of those kept in the water with genistein at a concentration of 100 micrograms per litre were female. A concentration of 400 micrograms per litre produced an all-female group, the same as in the female hormone-treated group.
