Abstract:
The catching efficiency of traditional traps: Ayunan and Tamba were tested in Sungai Batang River, South
Kalimantan of Indonesia. Trials consisted of 320-trap hauls/type using 1-day submersion time of 24 hr. The
baited traps sampling accounted for 82 specimens assigned to 5 species of 5 families. There was a large
variability in number of catch between prawns and fish species collected (T=2.318, P<0.05). The prawns catch
was represented by only the species Macrobrachium rossenbergii with total of 53 and 1,015 g weight. The
prawns weight of Tamba was significantly higher than that of Ayunan (T=3.453, P<0.01).The fish catch
composed of Mystus gulio 79%, Osteochilus hasselti 10%, Hypostomus plecostomus 7%, and Macrognathus
aculeatus 3%, with total weight ranged from 35 to 560 g. A clear difference was found in catching efficiency.
Comparative fishing trials showed that Tamba collected specimens were 1.8 times higher than Ayunan
(T=2.223, P<0.05). Catch per unit effort for Tamba ranged from 58.13 to 80.00, and for Ayunan ranged from
5.31 to 7.19. The gear modifications and various treatments (e.g. bait odor, light) are necessary to be taken to
increase their relative catching efficiency.
