Length-weight relationship and condition factors of Rabbitfish (Siganus guttatus, Bloch 1787) in Sei Carang Waters, Tanjungpinang City, Indonesia

Perairan Sei Carang merupakan perairan yang menjadi habitat ditemukannya ikan baronang (Siganus guttatus). Tujuan penelitian ini yaitu untuk mengetahui hubungan panjang-bobot dan faktor kondisi ikan baronang (S. guttatus) di perairan Sei Carang. Pengambilan sampel dilakukan seminggu sekali dari bulan September sampai bulan Oktober 2019 berdasarkan aktivitas penangkapan nelayan dan keadaan air. Hubungan panjang dan bobot ikan baronang (S. guttatus) betina dan jantan berturut-turut menunjukkan bahwa model pertumbuhannya adalah W = 2,0895E-05L2,9575 dan W = 1,30073E-05L3,0424, berdasarkan nilai tersebut pertumbuhan ikan baronang (S. guttatus) betina dan jantan di perairan Sei Carang yaitu isometrik (b = 3). Nilai faktor kondisi (K) ikan baronang (S. guttatus) betina dan jantan di perairan Sei Carang berturut-turut yaitu 1,735 dan 1,633.Sei Carang waters are baronang fish habitat (Siganus guttatus). The research was to determine the length-weight correlationship and condition factors of baronang fish (S. guttatus) in Sei Carang. Sampling of baronang fish (S. guttatus) in two months (September-Oktober 2019) is taken once a week based on fishing activities and water conditions. Length-weight correlationship of female and male baronang fish (S. guttatus) were W = 2,0895E-05L2,9575 and W = 1,30073E-05L3,0424 respectively, based on this value show that female and male baronang fish (S. guttatus) in Sei Carang have isometric growth patterns (b = 3). Condition factors of female and male baronang fish (S. guttatus) were 1,735 and 1,633 respectively
