| dc.description.abstract | Nowadays the ecosystem of Sibiru-biru river area was decreased, was shown from
decreasing fish found in that area. A study of fish diversity of Sibiru-biru river
has been done through sampling. Sampling design was based on Purpossive
Random Sampling, with four disticnt stations in terms of community activities
and coastal areas. Sampling was done in thirty repetitions for each stations. The
results showed that there were two orders of fish, four families, six genera and
seven species. The highest density of fish was from station 4 with density of 0.072
ind/m2
while being the lowest from station 1 with density of 0.048 ind/m2
. The
highest diversity index was from station 4 with value of 1.36 while being the
lowest from station 3 with value of 1.04. Species found in this research were
Oreochromis niloticus, Hampala macrolepidota, Mystacoleucus marginatus, Tor
soro, Tor tambroides, Channa striata, and Oxyeleotris marmorata. Velocity, light
penetration and light intensity was strongly correlated with the diversity of fishes. | en_US |
