PERTUMBUHAN RELATIF IKAN SELAIS (Ompok sp) YANG TERTANGKAP DI SUNGAI KAMPAR DAN SUNGAI SIAK, RIAU
Abstract: A study on relative
growth of Ompok sp obtained from the Kampar andSiak Rivers has been conducted
on April to June 2011. This study aims tounderstand the similarity and
differences of the fish that inhabit those rivers,Kampar River with good water
quality and Siak River that with poor waterquality. There were 84 fishes from
the Kampar River (in the Teratak Buluhvillage) and 31 fishes from the Siak
River (in the Tapung village) were capturedin this study. The meristical
characteristics were studied and the morphologicalcharacteristics were analyzed
to understand the relative growth of the fish. Resultsshown that there were no
difference in the meristical and morphologicalcharacteristics of the fishes
obtained from both sampling areas and its indicate thatthe fishes sampled were
belonged to a single species. Data also shown that almostall of fish’s body
morphometrical characteristics grow isometrically to total lengthand it means
that the fish was not showing any morphological changes as theygrow. However,
in the wegth-length relationship, the b values of the fishes fromboth sampling
area was less than 3 and its indicate that increasing in fish bodyweight was
slower than the increment of fish total length. Based on data obtained,it can
be concluded that there was no difference in relative growth pattern of
fishliving in the Kampar and Siak Rivers.
