The goldfish, a member of the carp family, is a widely used model for reproductive
neuroendocrine studies of economically important fish. The two gonadotrophin (GTH) …

Models are essential for the full understanding of neuroendocrine control processes. In this
regard fish offer a rich source of biological material. They have diverse growth and …
