Abstract

Abstract The Sail  River and Kampar Kiri River have different ecosystems characteristic and it may be reflected in the otolith’s growth ring patterns in the otolith of fish living in those areas. A research aims to understand the growth pattern present in the otolith of Pangasius polyuranodon. The fish were caught using nets and bamboo trap, once/week. There were 119 fishes (50 fishes from the River Sail and 69 fishes from Kampar Kiri River). The otoliths (sagita) were removed and processed following Windarti (2017). Growth  rings pattern was studied using a binocular microscope. The otolith in the Sail River length was 1- 2.175 mm and their weight was 0.0019-0.0075 mg. Whereas in the  Kampar Kiri River  length was 2-3.25  mm andtheir weight 0.0030-0.0267 mg. The  distance between the nucleus and the first dark ring was varied  from the Sail River (0.02-0.75mm) and Kampar Kiri River (0.025-0.75 mm). Results shown that the maximum number of dark ring in the otolith of fish living in the Sail River was 3, while that of the fish from the Kampar Kiri River was 4. Water quality in the sampling area was good and it may be suffcient to support  the life of Pangasius polyuranodon.   Keywords: Dark Ring, Otolith, Growth Pattern, Sagita

Abstract

Abstract            In the swamp area of the Sawah Village, the water quality is affected by pollutant originated from activities conducted around and in the swamp area.The low quality water may negatively affects the growth of Monopterusalbus and it is reflected in the growth pattern in the otolith of fish living in that swamp. A research aims to understand the pattern of otolith growth rings of theMonopterusalbuswas conducted in March to May 2018.The fish was captured using fishing gears, once/week. There were 61 fishes (31 females, 15 transitionand 15 males). The otoliths (sagita) is taken by tweezers and shaved using fine grindstone. Growth ring pattern in the otolith was studied using a binocular microscope. The length of otolith was 2.25-4.75 mm and weight 0.0040-0.0200 gram. Results shown that the  number of dark ring in the otolith of the fish ranged from 1 to 4. The distance between the nucleus and the first dark ring was varied (0.25-1.75 mm). These data indicates that the formation of dark ring may not be affected by periodical condition but it is affected by individual problem. The number of dark ring in otolith indicate that the fish is able to live properly in the swamp areas. Keywords: dark ring, sagita, freshwater eel, eel growth
