Ovarian development associated with first maturity in three Antarctic channichthyid species
It has been known for some time that yolk deposition and final ovarian maturation were prolonged processes for many Antarctic fish. The adolescent phase in three species of channichthyid has been studied, based on an extensive series of samples over five seasons. Samples were obtained during a serie...
