Abstract

organic material. This material may have been a mixture of sediment and semidigested tissue or detritus. The ingestion of sediment, detritus and associated bacteria has been demonstrated to be important to the nutrition of some crusta ceans (Fenchel & Jorgensen, 1977; Moriarty, 1976; Rieper, 1978). Marukawa (1933) suggests that the megalopa of king crab feed on detritus and bryozoans in the Bering Sea. In Cook Inlet, post-larval king crab ingest substantial quan tities of detritus and some bryozoans, but the crab are also capable of capturing ostracods and harpacticoid copepods. The ability of post-larval king crab to utilize detritus or bacteria as food needs to be investigated. Acknowledgements. ?
