Studies on food and fecundity of Notothenia gibberifrons Lönnberg, 1905 (Pisces, Notothenioidea) off South Georgia
The food of sympatric, immature and mature (longer than 37.5 cm l.t.) individuals of Notothenia gibberifrons is very diversified, the most important items being the Polychaeta, Euphausia superba, the Isopoda, and the Echinodermata. Ovaries of mature individuals contain two generations of eggs differ...
