Abstract

Ikan selar bentong (Selar crumenophthalmus Bloch, 1793) merupakan salah satu ikan ekonomis penting yang tertangkap di perairan Kwandang, Sulawesi Utara. Penelitian ini bertujuan untuk mengetahui biologi reproduksi ikan selar bentong. Pengumpulan data panjang berat, jenis kelamin dan tingkat kematangan gonad dilakukan dari periode Februari hingga November 2017. Jumlah contoh ikan yang diamati sebanyak 3.820 ekor. Hasil penelitian ini diperoleh persamaan hubungan panjang-berat ikan selar bentong yang diukur yaitu W = 0,0092 L3,1857. Nilai b dari persamaan ini adalah 3,18 yang mengindikasikan bahwa pola pertumbuhannya bersifat isometrik. Ukuran pertama kali matang gonad (Lm) adalah 17,69 cmFL. Rasio kelamin antara betina terhadap jantan yaitu 1 : 1,2. Musim pemijahan atau bersifat multiple spawner diduga terjadi antara Bulan November – Februari.Bigeye scad (Selar crumenophthalmus Bloch, 1793) was one of the important economic species in the artisanal fishery in Kwandang waters North, Sulawesi. The aim of this study was to determine the biological reproduction of big eye scad in the Kwandang waters, Sulawesi Sea. Data collection of lengths and weights, sex, and the gonad maturity stage were done between January-November 2016. A total of 3820 specimens was collected al together and examined in the study. The result showed that length-weight relationship for big eye scad were W = 0,0092 L3,1857. The exponent values (b slope) of length-weight relationship of big eye scad was 3,185 indicating isometric growth pattern. The length at first maturity (Lm) for bigeye scad was 17,69 cmFL. The sex-ratio between female and male was 1 : 1.2. The spawning season was estimated between November and February (multiple spawner).
1593年,在北部戈隆塔洛的昆当水里发现了SELAR BENTONG (SELAR crumenophthalmus Bloch)的生殖生物学家
沙勒本塘鱼(selar crumenophthalmus Bloch, 1793)是在苏拉威西北部的昆当当水域捕获的重要经济鱼类之一。这项研究的目的是了解水螅鱼的生殖生物学。在2017年2月至11月期间,长时间、性别和成长性的数据被收集。观察到的鱼类样本多达3820个。这项研究发现了一种测量为W = 0.0092 l3.1857的红球形鱼的重量方程。这个方程的b值是3.18,表示其生长模式是等距的。初熟甲状腺素(Lm)的尺寸为17.69 cmFL。女性与男性的性别比例为1:1.2。产卵季节被认为发生在11月至2月之间。Bigeye scad (Selar crumenophthalmus Bloch, 1793)是苏拉威西北部沃特斯北地区重要的经济物种之一。这项研究的目的是确定在苏拉威西海的沃特斯水域中大眼的生物复制。今年1月至11月之间的lengths和weights, sex和刚性舞台数据收集已经完成。3820个物种全部被收集并在研究中研究。最近的民意调查显示,大眼鳞片的固定功能是W = 0092 l3.1857。大眼睛鳞片的杰出关系是3.185英寸的生长不连续关系。bigeye scad的第一次阵痛是17.69 cmFL。女性和男性之间的求爱是:1.2。spawning预计在11月和2月之间。
