Proper Construction And Set Up Of Malaysian Fish Aggregating Devices (Unjam)

This study was carried out with an objective of improving the durability of unjams and determining the rational arrangement and optimum density of unjams . Several experiments were conducted in coastal waters of Terengganu in the South China Sea to determine a safe anchoring power of unjams an...

Several experiments were conducted in coastal waters of Terengganu in the South China Sea to determine a safe anchoring power of unjams and parameters required for the development of mathematical models that could produce an optimum trapping efficiency .Experiment s on anchoring power showed sandy bottom giving the highest value of fixing coefficient ( 0. 953 ) , foll owed by muddy bottom ( 0. 903 ) , and sandy -mud bottom ( 0.731 ) .
