Abstract

Rasbora sp. is one of native fish species that inhabit in Tamblingan Lake. Several publication that discussed about this species in other ecosystem was published, but very rare information in Tamblingan Lake. The aims of this research ware determine the length-length relationships, growth pattern and condition Rasbora sp. in Tamblingan Lake. Fish sampling conducted from January to December 2019 in Tamblingan Lake.
