Aspects of the reproductive biology of monkfish Lophius vomerinus off Namibia

L Maartens, A J Booth

Abstract


Aspects of the reproductive biology of monkfish Lophius vomerinus are described from material collected during hake Merluccius spp. biomass surveys and from commercial monkfish and sole Austroglossus microlepis vessels between January 1996 and June 2000 off Namibia at depths between 97m and 686m. Length-at-50% sexual maturity for males and females were estimated at 39.9cm and 58.2cm respectively, males maturing faster than females. The adult sex ratio of fish ᡪcm total length was strongly biased towards females. There was reproductive activity throughout the year, peaking slightly between autumn and spring.
