Evaluation of diets for culture of the calanoid copepod Gladioferens imparipes
Provision of copepod nauplii as food increases larval survival in many fish species that are difficult to rear using standard practices. Gladioferens imparipes is a temperate estuarine calanoid copepod with culture potential. Diets were tested to determine which would maximise copepod production. Copepods were fed five diets: Isochrysis galbana, Chaetoceros muelleri, Dunaliella tertiolecta, Nan...
متن کاملEcology and Zoogeography of Parasites
Parasitism is a ubiquitous phenomenon that is probably as old as heterotrophic organisms themselves. It is one of the major types of symbiotic relationship between organisms of different species. The development of the biological sciences brought about a broader definition of parasitism. By the end of the nineteenth century, it was known that parasites thrive at the expense of their hosts and u...
متن کاملPredation effects of the calanoid copepod
This study investigated feeding rates and selective feeding of the common copepod Acartia tonsa on mixtures of the heterotrophic dinoflagellate Protoperidinium cf. divergens and the cooccurring red-tide dinoflagellate Gonyaulax polyedra and predation effects of A. tonsa on the population growth of P cf. divergens during simulated red-tide and non-red-tide periods. Ingestion and clearance rates ...

15 صفحه اولEcology and energetics of two Antarctic sponges.
Retention efficiencies, pumping and respiration rates of the two Antarctic sponge species Mycale acerata and Isodictya kerguelensis from Potter Cove, King George Island, were measured. None of the species reached a 100% retention efficiency at any given particle size. This is probably due to the sediment-laden environment in which the animals were dwelling. A less efficient retention decreases ...
