| Cuturable heterotrophic bacterial counts (viable counts: VC) by surface plating on ZoBell medium and total bacterial counts (TC) by epifluorescence microscopy were carried out in sea water off the southwest coast of India during the monsoon. TC were three orders of magnitude higher than VC. Pseudomonas/Alteromonas group I was dominant in both nearshore and offshore regions. Pigmented bacteria were more abundant in offshore stations and showed multiple antibiotic resistance. Statistically there was found to be no significant differences in bacterial number and their activities between offshore and nearshore isolates. Nevertheless, the former tend to be more versatile and resistant to metals and drugs. |

| Observations of a fifty-day oscillation in the meridional component of the South Equatorial Current in the Western Indian Ocean are presented. Currents measured in 4000 m of water close to the atoll of Aldabra (46-degrees-E, 9-degrees-S) reveal the oscillation throughout the water column to a depth of 3 000 m. Further evidence of the oscillation is presented in shipboard Acoustic Doppler Current Profiler (ADCP) sections and in Coastal Zone Color Scanner (CZCS) imagery. The oscillations are consistent with a zonally propagating Rossby wave caused by shear instability in the zonal flow of the South Equatorial Current. |

| Since 1983, tuna purse seine fishery has increased rapidly in the Indian Ocean. This fishery, being mostly based in Seychelles, represents an excellent opportunity to this country. However, it is essential that a good management strategy be adopted in order to ensure the rational exploitation of the resources. Since this fishery is in its early stage of development, it is not yet possible to obtain an accurate assessment of the stocks based on usual stock assessment methods. Nevertheless, from existing knowledge on the Indian and Atlantic oceans, a preliminary analysis of the resources is attempted. Of the two stocks studied, the skipjack, known as an opportunist species, can support a higher exploitation rate than the yellowfin. It would seem that catches... |
