Species-specific genetic markers for identification of early life-history stages of Cape hakes, Merluccius capensis and Merluccius paradoxus in the southern Benguela Curren

摘要

The correct identification of fish egg and larval stages is crucial for inferring spawning areas and subsequent dispersal routes for marine fishes. The authors use species-specific mtDNA polymerase chain reaction to estimate proportions of Merluccius capensis and Merluccius paradoxus eggs and larvae and to elucidate early life stage distribution patterns in the southern Benguela system.
