Ecology
Fish bilih (Mystacoleucus padangensis) is a species of fish are estimated to only live in this lakeand became one of the specialties. Research experts revealed 19 species of freshwater fish living in habitats Lake Batur, Solok and Tanah Datar regency, West Sumatra (West Sumatra), the availability of food is limited.
Of the 19 species, three species of which have a high density of population, namely fish Bilih / Biko (Mystacoleusus padangensis Blkr), Asang / Nilem (Osteochilus brachmoides) and Rinuak. Other fish species that live in Lake Batur is, Turiak / turiq (Cyclocheilichthys de Zwani), Lelan / Nillem (Osteochilis vittatus), Sasau / Barau (Hampala mocrolepidota) and Gariang / Tor (Tor tambroides).
Then, the fish species Kapiek (Puntius shwanefeldi) and Balinka / Belingkah (Puntius Belinka), Baung (Macrones planiceps), Kalang (Clarias batrachus), Jabuih / Buntal (Tetradon mappa), Kalai / Carp (Osphronemus carp lac) and Puyu / Betok (Anabas testudeneus).
Furthermore, fish species sapek / Snakeskin (Trichogaster trichopterus), Tilan (Mastacembelus unicolor), Jumpo / Cork (Chana striatus), Kiuang / Cork (Chana pleurothalmus) and Mujaie / Mujair (Tilapia pleurothalmus).
With only 19 species of fish that live in Lake Batur shows the diversity of fish in places that are not are too high. Lake Batur mesogotrofik condition that causes this habitat carrying capacity for the development and growth of aquatic organisms such as plankton and Betos, very terbatas.Dari several times research shows plankton and Betos in Lake Batur very rendah.Padahal community of plankton (phytoplankton and zooplankton) is the basis of the formation of a food chain and play a pivotal role in an ecosystem danau.Kondisi, causing the main source of nutrients naturally fish generally are various types of plankton and benthos.
