Representative strains were found to be highly lethal to mice and also showed hemolytic activity. This suggests that virulent strains of <i>V. vulnificus</i> are present in fish and clams (seafood) harvested around Mangalore.

The genera encountered were <i>Streptomyces, Micromonospora, Nocardia, Streptosporangium, Micropolyspora and Streptoverticillium</i>. Of the total isolates 18% exhibited antimicrobial activity. The salt tolerance of the isolates was also tested.

It permits observation of development of marine microorganisms such as thraustochytrids for 3 d.

Productive value of upwelling, is reflected in the abundance of biomass of the total zooplankton. At much higher intensity of upwelling, the waters are very much depleted with respect to dissolved oxygen. Temporal and spatial lag of occurrence of zooplankton with upwelling is noticed in the analysis. Upwelling and plankton production take place earlier in the southern part of the coastline than in the northern. Page(s): 129-131 1987-06-01T00:00:00Z
