How do fish reproduce?

Fish can breed in two basic ways, according to the fertilization occurs inside or outside the female's body.We will pay special attention to the reproduction of fish in aquariums and the reproduction of fish for children, which we will exemplify in the clownfish, a fish that has achieved notoriety thanks to the children's movies Searching for Nemo and Searching for Dori .

Discover below in this article from Animals and Pets Online how fish reproduce :

Oviparos fish

We begin the explanation of how fish reproduce by talking about those oviparous species.They have an external fertilization , that is, the female lays eggs that are fertilized by the male outside their body.These eggs can be laid in the bottom by being denser, they can float, they can stick to the rocks or algae, or they can be protected in the mouth or in other parts of the body such as gill chambers.nests with different materials.

Fish that defend their eggs develop territorial behaviors .Since these eggs can be easily eaten by predators, oviparous fish must lay a large amount, To ensure survival, sea bream, trout, tuna, puffer fish, carp or sea bass belong to this group.

Viviparos fish

In this case, to explain how fish reproduce we must understand that we are facing an fertilization internal .Males fertilize the eggs that the female carries inside.The female stops the live young, called fry , who are born fully trained.This type of reproduction increases the chances of survival of the offspring.Some sharks belong to this group.

Ovoviviparos fish

Reproduction of this type is also a internal fertilization .Females can save sperm to lay eggs without the presence of the male.It executes rituals to attract it.She, after copulation , carries the eggs in its body.The offspring mature within the mothers and the eggs hatch or are expelled outside.The tiger shark, the white or the bull reproduce in this way.

Finally, around how the fish reproduce, it is interesting to know that some migrate to reproduce.Yes, the salmon live in the sea and at the end of their life they trace the rivers to spawn.They are anadromous fish .Instead, The eels live in rivers and, once ready to reproduce, descend to the sea where they spawn.They belong to the group of catadromous fish .

The reproduction of fish in the aquarium

If we want to increase the family in our aquarium we must take into account the following considerations:

Obviously, we must be clear about how the fish in our aquarium reproduce.
It is important to know that some fish are going to have sexual dimorphism , that is, males and females have different colors or sizes, which helps to differentiate them.
Other fish are going to be hermaphrodites , they can behave like males or females interchangeably, they can reach sexual maturity as females and become males or vice versa.
Depending on the characteristics We must have the space for our fish, so we must have the space, for example, if they are fish that spawn on rocks, they must have them at their disposal.
We must count on that in some cases there will be to separate the fry newborns, because their parents or the other fish could eat them.
Likewise, it is It is important that we reproduce the ideal conditions of their habitat.The temperature, pH, cleanliness and oxygenation of the water or food must be suitable.
Having a group of fish favors the reproduction success.
The food must be enough.Eye with the supercharging, since it could make us think that some female is pregnant.We will also have to take special care of the feeding of the fry.
We must pay close attention to our aquarium since some females may have reached us fertilized, as is the case with guppies.

The reproduction of fish for children

Lastly, in this section we will explain how the fish best known by children, the clown fish popularized by Nemo, are reproduced.As we have already said, it is essential that we have an aquarium with the characteristics suitable for the species The clown fish are oviparos and hermaphrodites .They present a ritual of laying and this is more common in the spring.

At the time of reproduction, what happens at approximately 2 years , the most dominant fish, usually the largest, will be the female .They will glue their eggs, orange and capsule-shaped, on plants, rocks or a simple pot.Shortly before laying them We can see the wider female and both clean their environment.The males are in charge of their care and we will see them swimming around them, moving the fins to oxygenate the water.Their color will change and they will hatch in 7-10 days , at sunset.

The fry will eat live food and it's good move them to another well-conditioned aquarium to prevent them from being eaten.Eggs can be moved.This is the stage that presents the most difficulty.Low light and feeding based on rotiferous and saline artemia are recommended.So much for this aspect as for anyone related to the care of these animals, we should always consult with experts.Finally, if we want to raise these fish at home we must ensure that the specimens have not been caught in the sea to preserve the environment.

Why do chow chow have blue tongues?

Chow chow's tongue is blue or purple due to the presence of pigment cells , that is, cells that contain elements called pigments that provide that color.Genetically they have a higher concentration of these cells and, therefore, have a different color to the other races.These cells, in addition to being in the tongue, are, above all, in the mucous membranes, that is why the chow chow is the only dog with lips, gums and palate characterized by being blue/blackish, if not almost entirely.
