dc.description |
Shrimp trawl net is the prominent fishing gear that beneficially supports shrimp industries in Kotabaru,
Indonesia. However, concurrently local fishermen have no idea how trawl works under towing condition. For
this reason, a flume test of a 1/8 scale model net with varying wing-end widths was undertaken. The flow
speeds of model were 48, 56, 64, 72, and 80 cm s–1. Meanwhile wing tips distance was set at 46–66% of headrope
length. At a towing speed of 64 cm s–1 (2-knot in full scale), the net height was 12 cm, the projective area
of net mouth was 9.16×102 cm2, water filtering volume was 58.44×103 cm3 s–1 and total net resistance was
6.34×102 g. The ratios of net height to net circumference ranged of 0.04–0.08. The net height was 5.5% of net
circumference and getting lower at higher towing speeds. The exponent value of 1.40 was smaller than the
suggested value (2.0) indicating the shape of net body should be refined by inserting triangle nets between the
side net and baiting. Moreover, the length of nets should be afforded to the lacing lines to increase the height
of net opening by better distributing the towing forces.
