Mating behaviour of Onychocamptus bengalensis (Copepoda, Harpacticoida, Laophontidae)


Abstract:
Onychocamptus bengalensis is an estuarine harpacticoid copepod that occurs commonly in Adyar estuary, Chennai, India. O. bengalensis is considered as a candid species for mass culture and is used in marine aqua hatcheries and hence knowledge on mating and spermatophore transfer might be useful for developing their culture protocols. The males and females measure 760 µm and 612 µm, respectively. The antennules of males are modified to hold the females during mating and transfer the spermatophore. Mating behaviour in this species consists of precopular and copular stages. During precopular stage, male grasps the P4 of the female in the fourth copepodid stage and secures paternity. In the copular stage, the male transfers a spermatophore to the female genital pore. In this paper, different stages of mating process and the reproductive potential of this species are described.
