Abstract

In this assignment a four panel prototype mid-water trawl was designed for the Fishery Survey of India, in particular the survey vessel MFV Sagarika for experimental mid-water trawling along the central west coast of India. The aim was to investigate the potential for pelagic fishing in the area and to promote the use of mid-water trawls as a substitute for bottom trawls. The design is based on basic formulas and calculations for the design of fishing gears and specific scientific reports on modelling and full scale tests of mid-water trawls. The design is also based on available knowledge on the behaviour and morphology of the targeted species. The resulting net plan is presented as conventional 2D blueprint and 3D model, visualising three optional hanging ratios (0.5, 0.3 and 0.2) and rigging.
