THE RECONSTRUCTION OF LOBSTER FOLDING TRAP ENTRANCE AND ITS UTILIZATION EFFECT ON CATCHES
To purpose of this study is to construct folding trap that give the highest captures and to prove cover is able to increases lobster catches. This research is carried out in the laboratorium using experimental design. One folding or standar folding trap (BS) and 2 modified construction trap are modified. Modified traps consist of modified folding trap 1 (BM-1) and modified folding trap 2 (BM-2) which take a cubical shape with dimention of 50×33×18 (l×w×h) (cm). BS entrance take a narrow slit-shaped while BM-1 and BM-2 is four rectangle with 33×6 (l×h) (cm) equipped with row of bars. Three traps and 20 lobsters are put in a water tank. Traps are lifted after immersed for 30 minutes. The activities of the lobster are observed and the numbers of lobster are counted. The catch experiments are carried out as much as 20 repeatation. The influences that produce the higest catch are also tasted. The result show that BM-2 capture 470 individuals more than BM-1 (221 individuals) and BS (109 individuals). The use of the cover will produce 227 individuals and without cover only 123 individuals.
