Pola Lingkaran Pertumbuhan Pada Otolith Ikan Kelabau (Osteochilus Melanopleurus) Dari Sungai Siak Dan Sungai Kampar

---

Abstract
Osteochilus melanopleurus can be found in the Siak and Kampar Rivers.
The Kampar Rivers waters are better than that of the Siak River and it affects the
the growth of the fish. The growth pattern is reflected on the pattern of otolith
growth rings. A research aims to understand the pattern of otolith growth rings of
the O. melanopleurus from both rivers has been conducted from January to
February 2021. There were 55 fishes captured (28 males and 27 females). The
otolith was taken using tweezers and shaved manually using a soft grindstone.
The dark growth ring pattern was investigated using a binocular microscope.
Result shown the size of fish captured was 220 to 360 mm from Siak River and
310 to 370 mm from Kampar River. In the fish with the same standard length, the
size of the otolith from the Siak River is heavier and longer than that of the
Kampar River, which means that fish growth from the Kampar River is better than
that of the Siak River. The length of otolith from Siak River ranged from 1.875 –
3.275 mm, the width was ranged from 1.575 – 2.75 mm and the the weight of
otolith was 0.0039 – 0.0098 g, while the length of otolith from Kampar River
ranged from 2.375 – 3.275 mm, the width was ranged from 1.85 – 2.575 mm and
the the weight of otolith was 0.0042 – 0.0076 g. The maximum number of dark
ring in the otolith from the Siak River was 4 and Kampar River was 2. The
distance between the nucleus and the first dark ring of fish from both rivers was
varied from 0.1 – 0.525 mm, and there was no special pattern. This fact indicates
that the first dark ring were formed individually and they were not formed by
periodical incident during the fish life.
