Title Basic principles of fishing gear design and construction
 
Names Boopendranath, M.R.
Date Issued 2002 (iso8601)
Abstract Fishing gears have generally evolved on a trial and error basis and until recently, only empirical approaches have been used to determine design parameters rather than analytical procedures. Design and development efforts based fish behaviour, engineering studies, system analysis and model studies taking into consideration resource conservation, ecological and economic issues have been taking place in the recent decades. With the development and wider availability of synthetic gear materials, recent advances in vessel technology, navigational electronics, gear handling machinery, fish detection methods and fish behaviour studies, large-scale changes have taken place in the design, fabrication, operation and catching capacity of modern fishing gears such as trawls, purse seines and long lines. Widely used traditional fishing gears such as entangling nets, hook and lines and traps have also benefited by way of design upgradation and efficiency improvement in the recent years. New innovative fishing systems such as electrical fishing, light-assisted fishing, FAD-assisted fishing and fish pumps have also been developed and accepted in different parts of the world. Design process for fishing gear has been greatly influenced in the recent years by the resource management and conservation, environmental safety
and energy efficiency imperatives.
