**5. Fish species used to mitigate HABs**

Fish species for all time used an option for bloom removal as number of fishes can ingest and digest the toxin itself. Therefore Bio-manipulation is a promising tool to control HABs for the lake-ecosystem [38]. High toxin production during bloom conditions [39] the massive fish kill was also reported, as its challenging for fishes to survive in oxygen-poor conditions, which suggest result another option to remove HABs [40].
