A Case Study To Understand The Feeding Strategy Of Some Selected Estuarine Copepods In Response To Mixed Phytoplankton Diet
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 9
Abstract
A preliminary study was performed to understand the feeding preference of some selected estuarine copepod species and their response to mixed phytoplankton diet. Acartia erythraea Giesbrecht, Paracalanus indicus Wolfenden, Oithona brevicornis Giesbrecht, Microsetella rosea Dana, Microsetella norwegica Boeck were selected for the feeding experimental trials. During the course of the study, all the selected species were fed with mixed microphytoplankton assemblage comprising centric diatom, pennate diatom and dinoflagellates. It was observed showed that all the selected species had higher feed preference for centric diatom than its pennate counterparts. Of the total feed consumed during the experimental process A. erythrae consumed 71% of the centric diatom, 27% pennate diatom and remaining 2% as dinoflagellates. Similar results were observed in case P. indicus (69% Centric; 31% Pennate), O. brevicornis (60% Centric; 38% Pennate and 2% Dinoflagellate), M. rosea (81% Centric Diatom; 19% Pennate Diatom) and M. norwegica (71% Centric Diatom; 29% Pennate Diatom) respectively.
