Abstract

The objectives of this study were to investigate the length-weight relationship and condition factor of crayfish living in the natural habitat of South Sorong and Jayawijaya Regencies, Papua, Indonesia. Three species of crayfish (Cherax monticola, C. albertisii and C. communis) were collected from Jayawijaya Regency and only one species of crayfish (C. snowden) was collected from South Sorong Regency. The growth coefficient (b) for each crayfish species ranged from 2.55 to 3.10. C. monticola from Jayawijaya Regency presented the highest b value (3.10), and C. snowden from South Sorong Regency showed the lowest b value (2.55). The condition factors (K) for each crayfish species ranged from 1.9 to 2.3. C. monticola and C. albertissihad the highest K value (2.3), whereas C. swonden demonstrated the lowest K value (1.9). The present study indicated that the values of b and K of crayfish living in Jayawijaya were higher than those from South Sorong probably because Jayawijaya habitat provides more suitable environment and better food supply for crayfish than South Sorong.
