Evolution of suitable Net for Medium Sized Vessels-ii Introduction of Large Meshed High paning Fish Trawl

Abstract

Large meshed high opening trawl was found to be very efficient for the exploitation
of column and off bottom fishes. The net is found more efficient than the bulged
belly trawl in capturing different varieties of column fishes comprising of squids,
pomfrets, barracudas, cat fishes, sharks and rays. The net offers 18% lesser resistance which in turn results in utilization of lesser horse power. The trawl is very simple in construction and requires minimum maintenance because of reduced number of meshes. The total cost of the net is less by 35% as the larger mesh size reduces the material requirement and cost of fabrication
