Abstract

The diversity of freshwater fishes on Manggarai, Flores Island is very poor. The result of first time exploration in 1994, there were Seventeen species fishes collected of 8 families, including 4 new record species, 4 introduce species from 21 sample sites, 18 rivers and 3 lakes. On a one month expedition in 1994 . The dominan family of fishes is Gobiidae. Habitat types are very variation, the reverine site is consisted of 18 rivers and 3 lakes, habitat types are consisted of 7 types. The habitat 2 is the most habitat type found. The characteristic of this habitat type is: Bottom: sand with large stones and pebbles, water is very clear, rapid current, pH: 3.91 - 8.51, conductivity: 20 - 186 u S/cm, and temperature during day light was 19 - 25.7 ° celcius. surrounded by primary forest,. AbstrakKeanekaragaman ikan air tawar di Manggarai, Pulau Flores adalah miskin. Sebanyak 17 jenis ikan dalam 8 suku telah terkoleksi, ini merupakan hasil pertamakalinya dari eksplorasi di tahun 1994, termasuk 4 jenis baru dan 4 jenis pendatang, semuanya terkoleksi dari 21 stasiun pengembilan sampel di 18 sungai, dan 3 danau.
