Data on length frequency of penaeid prawns landed by stake nets during lunar periods were analysed to assess variations in size composition and seasonal abundance. The full moon phase had lower size
Evolution of an Improved Trawl for Traditional Motorised Craft
12.77 m two seam trawl net designed for operation from 8.40 m OAL dug out canoe with 11HP outboard engine was field tested and the results compared, with 14.00 m two seam trawl net commonly used in
