Pengaruh Penambahan Probiotik Dengan Dosis Yang Berbeda Pada Pakan Terhadap Pertumbuhan Dan Kelulushidupan Ikan Betok (Anabas Testudineus) Dengan Sistem Resirkulasi
ABSTRACT
This research was conducted on from April – May 2020 at the Laboratory
of Aquaculture Technology, Faculty of Fisheries and Marine, University of Riau.
This research aims to obtain the best dose of probiotic added to feed for growth
and survival of Betok fish (Anabas testudineus) with recirculation system. This
research was using experimental method by completely random design (RAL) one
factor with four treatments and three replications. The treatments were: P0
(without probiotic), P1 (probiotic of 1 g / kg of feed), P2 (probiotic of 3 g / kg of
feed), P3 (probiotic of 5 g / kg of feed). The betok fish seeds used are 3-5 cm in
size with a stocking density of 400 heads/m3. The results showed that the of
probiotics with different doses in feed with the recirculation system has a
significant effect on the growth of betok fish, feed digestibility, protein
digestibility and feed efficiency, but had no significantly affect the survival of
Betok fish. The best treatment was P3 (probiotic of 5 g / kg of feed) with feed
digestibility of 74.5%, protein digestibility of 86.6%, feed efficiency of 73.23%,
absolute weight of 5.58 g, absolute length of 3.41 cm, specific growth rate 5.63%,
and survival 100%.
