Abstract

AbstrakWaduk Ir. H. Djuanda atau yang lebih dikenal dengan Waduk Jatiluhur mempunyai keanekaragaman jenis ikan yang tinggi. Namun saat ini mengalami penurunan produksi ikan yang diakibatkan oleh degradasi lingkungan, keberadaan spesies asing invasif dan aktivitas penangkapan. Alat tangkap yang banyak digunakan oleh nelayan adalah jaring insang. Jaring insang merupakan alat tangkap selektif yang mampu menangkap ikan pada ukuran tertentu berdasarkan ukuran mata jaring. Penelitian ini bertujuan untuk mengetahui ukuran optimal untuk eksploitasi beberapa jenis ikan dalam rangka pengelolaan sumberdaya ikan di Waduk Jatiluhur. Pengumpulan data sekunder dilakukan melalui penelusuran pustaka dan instansi terkait. Data primer diperoleh dari penelitian dengan percobaan penangkapan menggunakan jaring insang dengan ukuran mata jaring 1,0; 1,5; 2,0; 2,5; 3,0; 3,5 dan 4,0 inci serta wawancara dengan nelayan. Pemasangan jaring insang dilakukan di enam stasiun yaitu Muara Sungai Cihuni-Cibadak, Sungai Cikanyayan, Sungai Cirirp, Cihonje, Pasir Kole dan Cilalawi. Hasil penelitian menunjukkan bahwa ukuran optimal untuk eksploitasi ikan hampal, lalawak, nila, nilem dan tawes masing-masing adalah 25,5; 17,0; 21,5; 16,5 dan 25,0 cm dengan menggunakan jaring insang dengan ukuran mata jaring ≥ 3 inci.Kata kunci: Waduk Jatiluhur; jenis ikan; panjang total; jaring insangAbstractIr.

Abstract

Ikan bandeng ( Chanos chanos ) merupakan ikan penting yang bernilai ekonomi. Ikan bandeng banyak dikonsumsi karena memiliki nilai gizi yang tinggi. Ikan bandeng juga digunakan sebagai umpan hidup untuk memancing. Dalam sistem budidaya ikan bandeng peningkatan produksi merupakan faktor yang sangat penting. Salah satu upaya untuk meningkatkan produksi dalam sistem budidaya ikan adalah dengan menerapkan padat tebar yang tinggi. Kendala penerapan padat tebar yang tinggi menyebabkan pertumbuhan bandeng tidak merata, bahkan ada yang kerdil, yaitu kondisi ikan mengalami pertumbuhan yang lambat. Penelitian bertujuan untuk mengamati kondisi jaringan bandeng dengan ikan tidak kerdil dan kerdil. Ikan bandeng ( Chanos chanos) yang digunakan adalah ikan yang sudah dipelihara selama 6 bulan. Organ ikan yang menjadi sampel observasi adalah ikan stunting dan non stunting. Organ yang diamati adalah insang, otot, dan usus. Hasil penelitian menunjukkan bahwa bandeng ( Chanos chanos ) yang mengalami stunting mempengaruhi kondisi insang, otot dan jaringan usus. Insang mengalami edema dan nekrosis. Otot mengamati edema, merosot serat otot, dan nekrosis. Usus mengalami nekrosis atau kematian sel.

Abstract

The aim of this study was to investigate the effects of raw material freshness on the quality of marinated fish. The raw material anchovy (Engraulis encrasicolus) was divided into two batches. One batch (A) was kept at ambient temperature (20°C) for 6 h and the other one was kept at 0°C for 72 h. Then, they were marinated by soaking into marination solution containing 3% acetic acid and 8% NaCl. Total volatile basic nitrogen (TVB-N), trimethylamine (TMA), thiobarbituric acid (TBA), para-anisidine (p-Av) values in both marinated samples increased significantly during storage at 4°C. Increases in quality parameters were higher in samples produced with raw anchovy kept at 20°C compared to samples kept at 0°C. Although the sensory scores of both samples decreased during storage, higher scores were obtained for samples kept at 0°C compared to samples kept at ambient temperature. According to the results of the study, it has been determined that the quality of the raw material significantly (p0.01) affects the quality of marinated anchovy.Keywords: fish; quality; anchovy; marinade; raw material
