Última The autecology of the edible oyster Crassostrea cucullata Born, 1778: size related vertical distribution at Mkomani, Mombasa OceanDocs Ruwa, R.K.; Okemwa, E.; Polk, P.. The littoral oyster Crassostrea cucullata occurs between 1.05-3.35 m above chart datum with the highest density occuring between 1.85-2.75m. Its distribution is size-related as demonstrated by computation of correlation coefficients (r) and regression equations. The shell lengths (i.e. maximum linear dimension) decreases in an upshore direction. The analysis show high r-values which are significant at P<0.001. The elevation and density related effects on the shell lengths of the oysters are discussed.

Proceedings of the Second EEC Regional Seminar on Recent Trends of Research on Lake Victoria Fisheries, organized and hosted by Kenya Marine and Fisheries Research Institute (KMFRI), 25-27 September 1991, Kisumu, Kenya OceanDocs Okemwa, E.; Wakwabi, E.; Getabu, A.. Topics on Lake Victoria limnology, benthic fauna, stock assessment, catch assessment survey, gear selectivity, fisheries ecology, fish parasites and marketing economics are covered. Management and conservation of the lake's fisheries and other aquatic resources are discussed. Dialogue between fishermen, scientists and administrators is stressed, measures to be undertaken are addressed and further research is recommended.

A brief review is presented on some of the measures taken to manage Lake Victoria multispecies fisheries. It is suggested that management enforcement is not working. The linkage between research, policy making, industry and artisanal fishery is considered. The paper examines how the whole process of taking management decisions might be modified to take into account the realities of life in the riparian states around the lake and of the complexities and uncertainties of multispecies fisheries. Research and assessment are considered. Understanding the multispecies fisheries and characteristics of contemporary fisheries management are described. Recommendations for future research are given.

Fifty two free swimming planktonic copepod species were identified from the samples collected from three stations in Tudor Creek, Kenya. This appears to be the first systematic account of copepods reported from the coastal and inshore waters of Kenya.
