Ikan Teri (Stolephorus sp.) merupakan komoditas bernilai ekonomi di Pulolampes-Brebes umumnya ditangkap dengan jaring puring yang berbahan utama waring. Distribusi ukuran ikan teri berguna untuk mengetahui sebaran ukuran ikan teri dan informasi tentang stok, serta sebagai data dasar upaya pengelolaan dan pemanfaatan ikan teri. Penelitian ini bertujuan menganalisa komposisi ikan hasil tangkapan untuk mendapatkan keragaan struktur hasil tangkapan dan ukuran serta pola pertumbuhan ikan teri hasil tangkapan jaring puring. Lokasi pengamatan di sentra perikanan tangkap yaitu Tempat Pelelangan Ikan (TPI) Pulolampes. Waktu pengamatan pada bulan Maret-April dan Juli-Agustus tahun 2017. Metode pengamatan dilakukan dengan pengamatan selama operasi penangkapan (experimental fishing), pengambilan data secara purposive sampling. Pengukuran dan analisa menggunakan program SPR. Berdasarkan data hasil pengamatan diperoleh ikan teri yang terpanjang adalah 91 cm, dengan beratnya adalah 6,5 g, sedangkan ukuran yang terpendek adalah 29,8 mm, dengan beratnya adalah 2 gram dan modus ukuran 62,9 mm. Penangkapan ikan teri pada bulan Agustus 2017 lebih layak tangkap dibandingkan pada bulan April dan Mei 2017. Hasil perhitungan panjang dan berat tubuh ikan dengan menggunakan rumus maka diperoleh hasil di lokasi Perairan Pulolampes diperoleh b = 1,041. Dari hasil perhitungan menunjukan nilai b berada dibawah 3 menunjukkan pola pertumbuhan ikan teri di Perairan Pulolampes, Brebes bersifat allometrik negatif. berdasarkan pertumbuhan ikan teri yang bernilai allometrik negatif, menunjukkan pertumbuhan panjang tubuh lebih dominan dibanding pertambahan bobot. Keadaan ini mengindikasikan bahwa kondisi lingkungan Perairan Pulolampes Brebes cocok untuk pertumbuhan ikan teri dan masih aman dari tekanan aktivitas penangkapan.
Anchovies (Stolephorus sp) is one of the pelagic fish resources which has economic value and abundant in Indonesia waters. The fishing gear to be used to catch Anchovies is the waring purse seine. Demak is one of the fishing base of the waring purse seine in Central Java. This study aims to analyze the relationship between length-weight, the frequency distribution of anchovy length in Semarang, and Demak waters. This research used an explorative survey method, while the measuring method of fish samples was purposive sampling. Data for Anchovy were obtained in May and October 2018. The correlation between the length-weight of Anchovy in May obtained a value of b=2.759. The longest Anchovy (May) measuring 76.69 mm, weighing 8.8 g, while the shortest size was 34.17 mm, weighing 1.97 g and mode at the mean value of 58.50 mm. The correlation between Anchovy length-weight (October) obtained a value of b =2.126. While the longest Anchovy measures 94.06 mm, weighing of 5.94 g, and the smallest size was 43.68 mm, weighing of 1.44 g while the mode was 65.30 mm in the mean. The catch of Anchovy in October was more feasible to catch than in May.
