Abstract:

One of the artisanal fishing gears that are commonly used for fishing in the coastal area are fish traps. The
crucial part of fisheries management is lacking data on fish composition from trap in Malaysia. This kind
of data is really needed for fisheries stock enhancement. In 2019, 3,330 fishermen who used traps for fishing
were recorded and the total landing that year was 18 076 metric tonnes, respectively. While, in 2020, the
number of fishermen who used traps decreased to 3072 fishermen, the total landing in that year increased
to 22094 metric tonnes, respectively. The study's purpose is to show fish composition from the new
innovative squid trap at Batu Rakit, Terengganu. There were nine sampling stations at Bidong Island with
different water depths (10m, 15m, and 20 m), respectively. The fishing gear characteristics are 1.22x1.52
m dimension with mesh size 2 cm, respectively. The preliminary data was collected for two months, from
January 2022 to February 2022. Fish composition are Rachycentron canadum (n=11; 0.76%), Scarus
dimidiatus (n=9; 0.62%), Atropus atropus (n=6; 0.42%), Carangoides malabricus (n=2; 0.14%), Caesio
cuning (n=21; 1.45%), Siganus javus (n=16; 1.11%), Arius maculatus (n=5; 0.35%), Alectis ciliaris (n=4;
0.28%), Caranx ignobilis (n=10: 0.69%), Pomadasys maculatus (n=10; 0.69%), Lutjanus johnii (n=42;
2.95%), Diagramma pictum (n=22; 1.52%), Epinephelus malabaricus (n=18; 1.25%), Lethrinus microdon
(139; 9.62%), Lutjanus russellii (n=59; 4.08%), Carangoides Chrysophrys (n=9; 0.62%), Scolopsis
taenioptera (n=12; 0.83%), Cynoglossus arel (n=1; 0.07%), Lates calcarifer (n=1; 0.07%), Lutjanus vitta
(n=27; 1.87%), Chiloscyllium punctatum (n=19; 1.31%), Sepia officinalis (n=892: 61.73%), Pdophthalmus
vigil (n=78; 5.40%), and Portunus plagicus (n=32; 2.21%), respectively. In conclusion, the new squid traps
did not indicate any bycatches.
