Feeding habit, length weight relationships and condition factors of the tropical shortfin eel Anguila bicolor bicolor in Banda Aceh waters, Indonesia

[摘要] The objective of the present study was to analysis the bioecology especially on the feeding habit and growth pattern of the tropical shortfin found in Banda Aceh waters. The survey from October 2016 to September 2017 was conducted in Banda Aceh at two locations, namely in the reservoir of Tibang (Banda Aceh) and Lambaro Skep. A total of 45 samples of eel were caught during the study. The minimum size is 31 cm length and 45 g body weight, while the maximum size is 80 cm in length and 1100 g body weight. Histological analysis of the gonad showed that all samples are female and immature fish. The analysis of the stomach content showed that 12 samples are emptied and 33 samples are containing feed, where the fish fed on crabs, shrimps, small fish, and earthworms. In details, the crab was found in 22 fish samples (66.66%), shrimp was found in 18 samples (54.54%), small fish was found in 14 samples (42.42%), and earthworm was recorded in 3 samples (9.09). Analysis of the length-weight relationship showed that the b value was 3.54 indicate a positive growth pattern with Fulton's condition factor (K) ranges 8.32 to 10.35 (average 9.32 0.42) and relative weight condition factor (Wr) ranges 60.92 to 137.70 (average 101.6016.67), indicates that environmental condition and predator density is stable.
