Efek Biomassa Azolla Microphylla Terhadap Kelimpahan Plankton Pada Media Pemeliharaan Ikan Patin Siam (Pangasianodon Hypophthalmus)
Abstract
Azolla microphylla on the surface of the water can function as a phytoremediation
capable of providing nutrients so that it can increase the abundance of plankton.
This research was carried out in August-September 2021 at the Experimental
Pond and Laboratory of Fish Parasites and Diseases, Faculty of Fisheries and
Marine, Riau University. The purpose of this study was to determine the best
biomass of A. microphylla to increase the abundance of plankton in the
maintenance medium of Pangasianodon hypophthalmus using peat water. This
research method used a one factor completely randomized design (CRD) with
four treatment levels and three replications. The treatments in this study were
different A. microphylla biomass, namely AM0 (Control), AM1 (20 g m-2), AM2
(40 g m-2) and AM3 (60 g m-2). The results showed that the best treatment was
AM3 treatment (60 g m-2) which produced an average abundance of plankton of
8461 ind/L and was able to support the life of P. hypophthalmus for 28 days of
rearing. During the study, 12 species of plankton were found, namely
Climacosphenia moniligera, Cocconeis sp., Nitzschia acicularis, Synedra sp.,
Closterium sp., Chlorococcum sp., Scenedesmus sp., Anabaena sp., Pleodarina
sp., Brachionus bidentata, Monostyla sp. and Philodina roseola.
