Artificial reproduction in fish species encompasses a suite of techniques designed to overcome the limitations of natural spawning. By harnessing hormonal stimulation, controlled environmental ...

The process of vitellogenesis is fundamental to fish reproduction, involving the synthesis of vitellogenin (VTG) in the liver, its release into circulation and the subsequent uptake by developing ...

Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana ...

A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active – and spawn for the first time – ...

Contrary to what is stated in biology textbooks, the growth of fish doesn’t slow down when and because they start spawning. In fact, their growth accelerates after they reproduce, according to a new ...

A new study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might ...

A DNA probing technique clarifies the mechanism behind clonal reproduction of female dojo loach fish, also providing insight into the ancestral origin of the clonal population. A DNA probing technique ...

In the animal kingdom, reproduction is a necessary part of species survival. Parthenogenesis, a form of asexual reproduction where embryos develop from unfertilized eggs, has been observed in captive ...
