dc.description.abstractA survey was undertaken to study the body proportions of trawls operated for fish and shrimp from 40 to 48’ and 50 to 60’ trawlers of Kanyakumari district. The survey covered 17 parameters under each category of trawls. The body proportions of trawls surveyed were expressed as percentage of head rope length and used for comparison. The trawls were compared based on the percentage overlapping of body proportions. To estimate the catch per unit effort (CPUE) for different size class of trawls, catch effort analysis was made. The study revealed the need for gross modifications in fish trawls designs of both 40 – 48’ vessels and 50 – 60’ vessels, while the shrimp trawl designs of 40 – 48’ vessels of Kanyakumari district showed resemblance in most of the body proportions of FAO recommended trawl designs of Pajot (1987). Regarding shrimp trawls of 50 – 60’ vessels, attachment of jib, lengthening of belly besides marginally reducing the width of the belly were found to be the major modifications to be made to match the design of FAO recommended shrimp trawl of Akrehamn (1978). The study also revealed the general awareness of fishermen of Kanyakumari district on the cutting rate to be followed in the top and bottom wings of two seam demersal fish and shrimp trawls. The analysis of catch and effort revealed the maximum CPUE of 2.45 tonnes for fish trawls operated from 50 – 60’ size class vessels.en_US
