Can fish reproduce sexually or asexually?
While gonochoristic species, such as humans, can reproduce asexually, most fish species are gonochoristic. This means that they reproduce sexually, meaning that they need to have sex to produce offspring. However, there are fish species that can reproduce asexually. These are called parthenogenesis and it is the only known form of asexual reproduction in vertebrates.
Can fish reproduce without sex?
A few species of fish are known to reproduce asexually. One of the most famous examples is the asexual reproduction of the tiny, or “dwarf”, minnow, or the male and female “gynogenetic” salmon. This form of reproduction involves the production of female embryos by unfertilized eggs. If the male minnow sperm fertilize the eggs, the resulting embryos will be males, and if not, they will be females.
Can fish reproduce without sex in water tank?

Can fish reproduce without sex and eggs?
About a quarter of all fish species are hermaphrodites, meaning they have both male and female sex organs. These species can self-fertilize, which allows them to reproduce without the need for a mate. Unfortunately, they cannot produce viable eggs and do not lay them, so they are not technically capable of sexual reproduction.
Can fish reproduce without sex in water?
For those who are wondering if fish can reproduce asexually in water, the answer is no. There are no sexual fish in water. Instead, fish that reproduce without sex (gynogenetic or parthenogenesis) are freshwater species that reproduce using sexual reproduction in the egg cells.
