Abstract

Temperature varied from 17.6 to 28.5°C, salinity values from 32.12 to 35.21 x 10"" and dissolved oxygen from 0.8 to 4.41 ml/1. No identifiable relationship could be established between these three parameters and the total fish abundance, probably because the catch was made up of many species having different requirements. Higher abundance of trawl catches was from January to May when bottom water temperature was relatively low. The highest level of abundance of 2764 kg/hr in February 1989 was recorded when the parameters were 26°C, 33.6 x 10" and 2.71 ml/1; and the lowest level of 43.2 kg/hr in July 1988 was when the parameters were 25.3°C, 34.48 x 10'^ and 1.6 ml/1.
