Abstract

Oreochromis niloticus (Linnaeus, 1758) is native species to North Africa, that has been introduced to many areas worldwide, including Indonesia. On 10-24 January 2020 specimens of O. niloticus were captured from Laine Waterfall in Sangihe Island, Indonesia, as a new record for this island. Introduced non-native fish would be able to have negative impacts on the aquatic species communities through competition food and other resources, so the existence of the O. niloticus is a risk. The characteristics of O. niloticus specimens were as follows dorsal spin rays 15, dorsal soft rays 11, pelvic spin rays 1, pelvic soft rays 5, pectoral fin rays 10, anal spin rays 8, anal soft rays 10. The specific morphological characters of a specimen are provided.
