Reproductive biology of notothenioid fish - Analysis of gonadal development from a number of species

Fish species of the suborder Notothenioidei were captured in the McMurdo Sound or Terra Nova Bay region and basic biological measurements were taken for all fish (length, weight, gonadosomatic indices, sex, etc). For most species, a variety of gonads covering various developmental stages were collected and fixed for histological work. A number of individuals from 10 species were captured including Pagothenia borchgrevinki, Trematomus pennellii, T. bernacchii, T. nicolai, T. hansoni, T.newnesi, T. eulepidotus, Gymnodraco acuticeps, Chionodraco hamatus and Lyodichthys dearborni.
