| Abstract | The present study provides the first reference for the growth patterns and relative condition factor of Macrobrachiumspecies from Sungai Batang River, Indonesia. A total of 328 specimens, caught by using wire-stage trap, consisted of 83 males(25%) and 245 females (75%) with the sex ratio of 1:3. Macrobrachium species showed a negative allometric growth pattern (b= 1.94-2.14). The highest percentage of catch falls between 90-94 mm TL (38.55%) and weighted between 9-10 g (46.99%). Theaverage total length and body weight of male were 1.1 and 1.4 times greater than those of female computed by comparing thesaid body sizes of shrimp. Male had total length, carapace length, abdominal length and chelae length longer than female. Themean relative condition factor values ranged of 0.96 ? 0.17 and 1.01 ? 0.16, reflecting well-being of the species. Outcome ofresearch could be useful for sustainable fisheries management and conservation measures for Macrobrachium species in thisriver. In addition, a new fishing method was also introduced to improve fishing efficiency. |
