Keanekaragaman Ikan Air Tawar Sistem Sungai Siret dan Vriendschap, Asmat–Papua
ABSTRACT: Geologically
southern part of New Guinea Island is the oldest part of the mainland and have
most speciose of freshwater fish. Asmat is one area in Southern New Guinea
where has some large river systems such as Siret and Vriendschap Rivers. There
is not much information on freshwater fish diversity of the area. This study
aim to know freshwater fish species of both river systems, in order to manage
the area as conservation area by local government. Active fish collection
method was applied to sample fish of Siret and Vriendschap River Systems. One seine
net, 3.6 m length, 1.23 m in height, and with a mesh size of less than 0.5 cm,
and traditional scoop net were used to collect fish. The Siret and Vriendschap
freshwater fish fauna consist of 22 species in 18 genera and 15 families.
Cochlefelis danielsi (Ariidae), Mogurnda cingulata (Eleotridae), Zenarchopterus
novaeguineae (Hemiram-phidae), Melanotaenia ogilbyi (Melanotaenidae), Synaptura
villosa (Soleidae) are endemic to Southern New Guinea. Spesifically, Mogurnda
cingulata (Banded Gudgeon) and Melanotaenia ogilbyi (Ogilbyi’s Rainbowfish)
have restricted distribution in Southern New Guinea. Further research in
smaller stream and its tributaries might increase freshwater fish diversity of
Asmat.
