Abstract

Abstract. The objective of the present study was to analyze the morphometric variationsof five predominant fish species caught in Lake Aneuk Laot, Sabang City,Weh Island.The study was conducted in December 2015 to January 2016. The survey method was used in this study. The fish target were Nile tilapia (Oreochromis niloticus), tilapia (O. mossambicus), snakeskin gourami (Trichopodus pectoralis), giant gourami (Osphronemus goramy) and snakehead (Channa striata). The fish samples were catched using gillnets. The fish sample were analyzed for traditional and truss network morphometrics. The results showed that there is closed morphological relationship between Nile tilapia and tilapia, and between snakeskin gourami and giant gourami, while the snakehead fish was discriminated apart from the two previous groups.Keywords: Morphometric Nile tilapia, tilapia, snakeskin gourami, giant gourami, snakehead fish, Weh Island Abstrak. Penelitian ini bertujuan untuk menganalisis variasi morfologi ikan hasil tangkapan dominan di Danau Aneuk Laot Kota Sabang dengan menggunakan teknik traditional dan truss morphometric. Penelitian dilakukan pada Desember 2015 sampai Januari 2016. Ikan sampel terdiri dari ikan nila (Oreochromis niloticus), ikan mujair (O. mossambicus), ikan sepat siam (Trichopodus pectoralis), ikan gurami (Osphronemus gorami) dan ikan gabus (Channa striata). Ikan sampel diperoleh dengan menggunakan alat tangkap jaring. Sebanyak 12 karakter traditional morphometric and 14 karakter truss dianalisis dalam penelitian ini.  Hasil penelitian menunjukkan terdapat tiga kelompok ikan, kelompok pertama ikan nila dan ikan mujair, kedua ikan ini kemiripan yang tinggi; kelompok kedua adalah ikan sepat siam dan ikan gurami, kelompok ketiga adalah ikan gabus yang memiliki kemiripan yang jauh dengan kedua kelompok ikan sebelumnya.Kata kunci: Morfometrik, Nila, mujair, sepat siam, gurami, gabus, Pulau Weh

Abstract

Abstract. The aims of this research was to examine the water quality parameters and plankton abundance and its relationships in the Southwestern of Indian Ocean. This is a quantitative descriptive research. Planktons were sampled using plankton net, and water samples were taken using Conductivity, Temperature, Depth (CTD) where the water samples colleted in the Nansen Bottle No. 1 (surface water) at seven sampling stations. The results showed that there were 25 species of planktons belonging into seven classes, i.e., Bacillariophyceae, Ciliate, Crustacea, Cyanobacteria, Dinophyceae, Flagellata, and Maxillopoda. The highest value of abundance of plankton was found at station 6 with 7255 ind. L-1, the value of diversity index of plankton was at moderate category,  and there was no predominant species was occurred in the community. Bivariate correlation analysis results of Person's showed that the temperature and Dissolved Oxygen (DO) were positively correlated to the plankton abudance, while pH, conductivity, TDS, salinity were negatively correlated with abundances of plankton.Keywords: Abundance of plankton, linkages, water quality, Indian Ocean of Southwestern Abstrak. Penelitian ini bertujuan untuk mengetahui jenis dan kelimpahan plankton dan kualitas air serta hubungan antara kelimpahan plankton dengan parameter fisika-kimia perairan di Samudera Hindia bagian Barat Daya. Penelitian ini merupakan penelitian deskriptif kuantitatif, pengambilan sampel plankton menggunakan plankton net, dan sampel air menggunakan CTD (Conductivity, Temperature Depth) dimana sampel air yang diambil pada botol nansen No. 1 (sampel air permukaan) pada 7 titik stasiun. Hasil penelitian ditemukan 25 spesies plankton yang termasuk ke dalam 7 kelas, yaitu Bacillariophyceae, Ciliata, Crustacea, Cyanobacteria, Dinophyceae, Flagellata, dan Maxillopoda. Kelimpahan plankton tertinggi terdapat pada  stasiun 6 dengan 7255 ind/L, indeks keragaman plankton pada kondisi sedang, dan tidak terjadi dominasi spesies dalam komunitas. Hasil analisis korelasi Bivariate Person’s menunjukkan suhu dan DO (Dissolved Oxygen) berkorelasi positif terhadap kelimpahan plankton, sedangkan pH, konduktifitas, TDS, salinitas berkorelasi negative dengan kelimpahan plankton. Kata kunci: Kelimpahan Plankton, Keterkaitan, Kualitas air, Samudera Hindia bagian Barat Daya
