- Abstract
Substrates play an important role in the growth and survival of the freshwater crab Barytelphusa cunicularis as it is aggressive and has agonistic behaviour. An experiment was conducted to study the survival and growth performance of the freshwater crab Barytelphusa cunicularis using different substrates: T2 (Mud: Stone 50:50%), T2 (Mud: Stone 75:25%), T2 (Stone: Mud 25:75%), T2 (Mud 100%), T2 (Stone 100%), T2 (Tiles 100%), T2 (PVC pipe 100%) and T2 (Tiles: PVC pipe 50:50%). Crabs of initial average carapace width (6.3 ± 0.11cm) and average weight (80.85 ± 2.50 g) were reared in a 100 L HDPE circular tank for 60 days, crabs were fed daily trash fish at 5% of the body weight. A significantly higher carapace width gain and weight gain was observed in tiles: PVC pipe. No significant difference was observed in survival among the treated groups. This study concluded that Barytelphusa cunicularis prefers an open-tank artificial substrate. Similarly, the setup of a substrate containing tiles: PVC pipe substrate was most preferred in HDPE tanks as compared to other treatments. Tiles: PVC pipe substrate was used in successful trials for maintenance and hiding places for protection from predators, to avoid mortality rates and to minimize intraspecific struggle in Barytelphusa cunicularis. It was suggested as the best system for crab culture and maintenance.
