Abstract

Mimi merupakan organisme yang mendiami daerah Muara Sungai Paluh Sebilang. Namun informasi tentang mimi di daerah tersebut belum ada. Untuk memahami/mengetahui jenis mimi yang ada di muara sungai Paluh Sembilang,  penelitian ini telah dilaksanakan pada bulan April 2019. Daerah pengambilan sampel berada di sekitar pantai dan muara sungai Paluh Sembilang. Pengambilan sampel mimi dilakukan setiap hari selama dua minggu. Mimi ditangkap menggunakan mini trawl dengan mesh size 50 mm atau 2 inch dan mimi yang berada di pantai dapat di pungut langsung menggunakan tangan. Karakteristik morfometrik dan meristik mimi dianalisis secara deskriptif. Sampel mimi kemudian diidentifikasi. Terdapat 138 ekor  mimi (67 jantan dan 71 betina). Spesies mimi yang ditemukan terdiri dari dua spesies, yaitu Tachypleus tridentatus (61 Jantan dan 67 betina) dan Carcinoscorpius rotundicauda (6 Jantan dan 5 betina). Masing-masing dari setiap spesies memiliki karakter morfologi yang berbeda. T. tridentatus memiliki ukuran tubuh besar (33,08-34,89 cm) dengan warna abu-abu kehijauan. Sedangkan C. rotundicauda memiliki ukuran tubuh kecil (27,38-25,8 cm) dengan warna hijau tua hingga coklat kehijauan. Pola pertumbuhan relatif menunjukkan bahwa pertumbuhan jantan lebih cepat daripada betina.

Abstract

AbstractMystus nigriceps commonly inhabit the Tarai River that is polluted by tofu industrial liquid waste. Low water quality may affects fish growth and that is reflected in the growth ring pattern of the otolith. A research aims to understand the pattern of otolith growth rings in the M. nigriceps was conducted in April to May 2019. The fish was captured  using a cast net, and a scoop net. There were  90 fishes captured (31 males and 59 females). The otolith were removed and shaved. The dark growth ring pattern was investigated using a binocular microscope. Results shown that the standard length of the fish ranged from    75.11 to 150.44 mm and their body weight was 3.27 to 44.82 g. The otolith length was 1.375 to 2.625 mm and its width was ranged from 0.85 to 1.375 mm. Among the fish captured, 82 of them having 1-3 dark rings, indicate that the in certain period the growth of fish in the Tarai River is hampered. The distance between the nucleus and the first dark ring was 0.25 to 0.625 mm and there was no special pattern in the formation of the first dark ring. This fact indicate that the first dark rings are formed individually and it is not formed by periodic events in fish life. The water quality parameter value are as follows, temperature 27-280C; pH 6;  DO 3.2-3.5 mg/L; and CO2 23.09-24.98 mg/L) and it is able to support the life of fish. Keywords: dark ring, growth ring pattern, sagita, catfish, polluted river
