ABSTRACT
Mahseer fish Tor soro, an endemic species in Indonesia, is currently declining its population due
to the overreliance on wild captures to meet consumption demands. Furthermore, the survival rate
of fry is alarmingly low, necessitating the implementation of sustainable fry cultivation initiatives to
bolster the demand for Mahseer fish. Environmentally friendly aquaculture practices, particularly those
employing the zero-water discharge principle, offer a promising solution for establishing Mahseer fish
nurseries. In cultivation methods, adding bottom substrates to resemble the natural habitat of Mahseer
fish can enhance their physical performance and improve fish welfare. This study aimed to evaluate
the effects of different substrates on the nursery of Mahseer fish, specifically utilizing (A) coral rock,
(B) limestone, (C) crushed stone, and (D) no substrate (control) as treatments. The results demonstrated
that the use of substrate media in the cultivation tanks positively influenced water quality, stress levels,
and production performance of Mahseer fish. Among the treatments, the utilization of coral rock (A) as
a substrate medium yielded the best results in terms of water quality, stress response, and production
performance throughout the study compared to the other treatments.
