Ship based observations during early March 2007 in oceanic waters of the Northeastern Arabian Sea followed by phytoplankton analysis indicated that the bloom Noctiluca miliaris, species of dinoflagellate, dominated oceanic waters of the basin during winter. Dark green discoloration was observed during February-early March. During the cruise FORV SS-212 Sagar Sampada in February-March 2003, surface water samples measured 64-4128 cells.l -1 and deeper layers (10-15 m) supported 1080-2542 cells.l -1 of Noctiluca. Chlorophyll concentrations were in a range 0.4-2.0 mg.m -3, which reflect unusually high primary production in the deep waters (>2000 m). A pattern of zooplankton showed unusually high growth in the bloom waters. Fish catch data (% hooking rates of tuna) were obtained from Fishery Survey of India and were used to study response of fish to prevailing high productivity in the bloom waters. Fishing in oceanic waters within Indian EEZ indicated no adverse effect of bloom; rather remarkably higher catches resulted from long line operations in the bloom waters. Space-time variability in dissolved oxygen was studied to explain the observed preference of fish in the bloom waters.

Women in fishing communities are major players in the post-harvest sector and are traditionally involved in processing and marketing of fish. The issue of women's limited control over resources has been discussed widely and there is need to develop micro-level interventions together with macro-level advocacy as a strategy to strengthen women's role in post-harvest activities and in preparing and marketing of value-added fish products. In marine fisheries, while high value species are mostly processed for export, most of the medium and low value species, which form bulk of the landings, are marketed fresh or processed for the domestic market. Women perform their tasks either at home or as labourers in commercial processing units. However, they fail to realise the benefits to support themselves as well as family. Location-specific and need-based training programmes for fisherwomen can enhance their technical know-how and awareness enabling them to start gainful employment ventures. The economic feasibility of fish based value added items by self help group (SHG) group micro-enterprises is discussed in this paper.
