Abstract
Penelitian mengenai pertumbuhan dan status eksploitasi ikan sembilang (Plotosus canius) penting dalam menunjang pengelolaan sumberdaya ikan di Perairan Kota Tanjungpinang, Kepulauan Riau. Penelitian bertujuan untuk mengetahui pola pertumbuhan, parameter pertumbuhan, dan status eksploitasi ikan sembilang di Perairan Kota Tanjungpinang, Provinsi Kepulauan Riau. Penelitian dilakukan dengan metode purposive sampling sebanyak 3 stasiun dengan jumlah sampel yaitu 529 individu. Analisis data pertumbuhan dan status eksploitasi menggunakan software FISAT II dan analisis regresi menggunakan Excel 2017. Pola hubungan panjang-bobot ikan sembilang betina dan jantan adalah allometrik negatif (pertambahan panjang lebih cepat daripada pertambahan bobot). Status eksploitasi ikan sembilang paling tinggi sebesar 0.73 per tahun. Nilai eksploitasi telah melebihi nilai eksploitasi optimum 0,5.
Abstract
Research on the growth and exploitation status of indian catfish (Plotosus canius) is important in supporting the management of fish resources in the waters of Tanjungpinang City, Riau Islands. The study aims to determine the pattern of growth, growth parameters, and the status of indian catfish exploitation in the waters of Tanjungpinang City, Riau Islands Province. The study was conducted with a purposive sampling method of 3 stations with a total sample of 529 individual fish crosses. Analysis of growth and exploitation status data using FISAT II software and regression analysis using Excel 2017. This study resulted in a pattern of long relations and the weight of fish as a female and males both are negative allometric (faster increase in length than weight increase). The highest rate of exploitation of indian catfish is obtained from the data of 0.73 per year. This exploit value exceeds the optimum exploitation value of 0.5.
