ABSTRACT
Total bacterial counts and five different groups in sea water were investigated from May 1998 to May 1999 at two Avicennia marina L. inter tidal sites 1 and 2 and a control A.marina free site 3. The highest total bacterial counts in sites 1 and 2 waters were recorded during June and September 1998 respectively. However, site 2 exhibited higher total counts and showed an additional smaller total count peak during November. Proteolytic, cellulolytic, amylolytic and lipolytic bacterial group counts followed similar trend in sites 1 and 2. Although amylolytic and proteolytic counts were higher in site 1. Lowest numbers were recorded during the winter months. Site 3 recorded peak counts for the different groups during June-July and were of the same order as site 1 but lower than site 2 except for the proteolytic group which was higher than that for sites 1 and 2. Spore formers in all sites were several orders of magnitude lower than other groups. In general, the study showed that bacterial counts were higher during warmer months. Water temperatures had great influence on bacterial counts compared with other environmental parameters studied.
