Influence of size, age and maternal condition on the oocyte dry weight of Argentine hake (Merluccius hubbsi)
Effects of maternal age-size and condition on oocyte dry weight were analysed for Merluccius hubbsi. Samples of mature females were collected in the Patagonian spawning area during 10 research surveys carried out between 2000 and 2005. Dry weight of 50 hydrated oocytes ranged from 0.80 to 1.90 mg.
