Further investigations on the relative efficiency of different shaped otter boards
Horizontal curved, vertical curved and V-shaped otter boards were studied to compare their relative efficiency under identical fishing conditions. The gear operated with V-shaped otter boards performed well followed by the gear fitted with horizontal curved boards. Vertical curved boards were found to be comparatively less efficient, but with slight modification, can be used advantageously for bottom and off bottom fishes. Fishing at various depths with horizontal curved and V-shaped otter boards at different scope ratios showed better performance of horizontal curved boards at a scope ratio of 1:6 and V-shaped otter boards at a scope ratio of 1:5.
