REPRODUCTIVE CHARACTERISTICS AND GROWTH OF INVASIVE PRE-MATURED SUCKERMOUTH-AMOURED CATFISH (Pterygoplichthys spp.) IN KHANH HOA PROVINCE, VIETNAM
Pterygoplichthys spp. is an invasive alien species distributed in most water bodies of southern Vietnam. Pre-matured fish (70 - 188 mm in length) were sampled from Am Chua canal (12o17.436' N, 109o6.063' E) in Khanh Hoa province, Vietnam and analyzed for reproductive and growth characteristics. Morphology analysis of gonad of these fish indicated that sex of small fish (≈ 8 cm in length, 4 g in weight) could be distinguished using naked eyes. Male to female ratio for the population was 1:1. Weight of gonad at stage I was significantly smaller those at stage II (both collected at the same and different sampling period). Fish at pre-matured stage tended to grow in length more than in weight (b<3). Research results indicated that this species had diverse reproductive characteristics and well adapted to water bodies in south Vietnam.
