ASPEK BIOLOGI REPRODUKSI IKAN SELINCA (Belontia hasselti) DI DESA TERANTANG KECAMATAN TAMBANG KABUPATEN KAMPAR PROVINSI RIAU (Reproductive Biological Aspect of Belontia hasselti in the Terantang Aquatic at Tambang, Kampar District, Riau Province)
(2012-10-16) Simanjuntak, Esa F
Belontia hasselti is belonged to Belontiade family and commonly inhabit in the flood area in the riverside in Riau. However, information on reproductive biology of this fish is rare. To understand the reproductive biological aspects of this fish, a research has been conducted on February-April 2012. There were 123 fishes (102 males and 21 females) captured and TL is ranged from 52 to146 mm and BW ranged from 2 to 68 gr. The sex ratio of male and female is 5:1. In each sampling time there were fishes with 1st, 2nd, 3rd and 4th maturity level. The Gonado Somatic Index (GSI) is arround 0.01-10.46 %. Fecundity is around 142-10,041 eggs. Relationship between fecundity and TL is weak (r=0.03), while the relationship between fecundity with BW and GW are strong, r=0.99 and r=0.99 respectively. The egg size less various, around 0.98-1.00mm in diameter. However, the maturity stages of eggs in the ovary is various. In the 1st maturity level, the eggs are non vitellogenic with 0.05-0.18mm in diameter. In the 2nd maturity stage, the eggs are bigger 0.15-0.44mm and several eggs are in early vitellogenic stage. In the 3rd maturity level, eggs diameter is arround 0.28-1.95mm and there were several vitellogenic eggs. In the 4th maturity level, most of eggg in the ovary are mature (fully vitellogenic), 0.3-0.5mm in diameter. However, in the ovary of the 4th maturity stage fish, there are many immature eggs. This evidence indicates that B. hasselti may be a “partial spawner” and may spawn their eggs throughout the year.

Pola Lingkaran Pertumbuhan Pada Otolith Ikan Selais Ompok hypophthlmus yang Tertangkap Dari Sungai Siak Dan Sungai Kampar Provinsi Riau
(2013-01-07) Nurullah
Siak River is known as a river that has poor water quality in Riau due to pollutants. Water quality in the upstream, however is better than that in the downstream, as there is few pollutant agent enter the water body in that area. As water quality affect the growth of fish, fish that inhabit the upstream of the Siak River may grow up properly. Information on fish living in the upstream of the Siak River, however, is limited. Many studies focus more on the biology of fish living in the downstream of the Siak River. To understand the growth of fish from the upstream of the Siak River, this study was conducted. Fish growth was studied through investigating the growth ring pattern present in the otolith. The pattern was then compared with the otolith growth ring pattern of fish obtained from the Kampar River that has good water quality. In this study, Ompok hypophthalmus, captured from the Siak River (78 fish) and Kampar River (82 fish). The otolith (sagita) were removed and shaved using stone sharpener (following Windarti, 2007). Results shown that the otolith growth ring pattern of fish captured from both sampling areas was almost the same, they have 1-3 dark rings. The otolith weight of fish of the same size also not significantly different, the otolith of the Kampar’s fish is slightly heavier (3,2) than that of the Siak fish (5,9). This fact indicate that fish living in the upstream of the Siak River grow as well as fish living in the Kampar River and also indicates that the water in the upstream of the Siak River is suitable for supporting the life of fish living in that area.
