Project KEN/74/023 Offshore Trawling Survey, Work Report no. 6: Line fishing during the survey period 1979–1981.

Abstract

With four hand operated snapper reels have been fished on, for R/V UJUZI, non trawlable grounds mainly on the North Kenya Bank. The catches have been analysed by region, season and depth and compared with handline oatches. Average catch rates on the North Kenya Bank ranged from 2-3-6.4 kgs/reel-hour, highest in the depth range 16-75 meters during the south-east monsoon period. In other areas the average catch rates were below 1 kg/reel-hour. In the north-east monsoon period the family Lutjanidae formed the bulk of the catches, with two species Lutjanus sanguineus and Pristipomoides (~ clearly depth restricted. In the south-east monsoon period the family Serranidae dominated with its speoies EPinephlus tauvina especially in the shallower waters.
