Abstract

Penelitian ini bertujuan untuk mengetahui kelimpahan, komposisi ukuran dan pola pertumbuhan udang galah (Macrobrachium resenbergii) pada habitat perairan Sungai Ogan yang terletak di Kabupaten Ogan Ilir, Provinsi Sumatera Selatan. Penelitian ini merupakan penelitian eksplorasi dengan metode survei. Data primer utama dalam penelitian ini adalah ukuran panjang total dan bobot udang galah. Hasil penelitian didapatkan jumlah total udang galah sebanyak 127 ekor yang didominasi oleh udang galah betina sebanyak 83 ekor dan 44 ekor jantan. Ukuran sebaran  bobot dan panjang udang galah betina terdapat 8 kelas dengan nilai tertinggi yaitu 53 gram dan 18,2 cm. Sedangkan sebaran bobot dan panjang udang galah jantan terdapat 7 kelas dengan nilai tertinggi  297 gram dan 27 cm. Hubungang panjang dan bobot menunjukkan bahwa pola pertumbuhan udang galah pada habitat Sungai Ogan yaitu bersifat alometri negatif (b <3) yang artinya pertumbuhan panjang lebih cepat dari pertumbuhan bobot. Secara keseluruhan hasil tangakapan udang galah didominasi oleh udang muda yang seharusnya dapat tumbuh lebih besar lagi. Oleh karena itu, untuk menjaga kelestarian populasi udang galah di perairan Sungai Ogan, Kabupaten Ogan Ilir, Provinsi Sumatera Selatan diperlukan pemahaman pada nelayan sekitar tentang ukuran udang galah layak tangkap.

Abstract

Fish is one source of animal protein that is widely consumed by society, is easy to get, and the price is cheap. But fish quickly experience the process of decay. Therefore, fish preservation should be known to all levels of society. One of the products of fish processing through the process of preservation is abon. Abon fish is a type of preserved food made from fish that are seasoned, processed by boiling, frying and pressing or separating oil. The resulting product has a soft shape, good taste, distinctive smell, and has a long-lasting power. This study aims to examine the effect of fish species and the method of cooking fish meat is the steaming and boiling treatment of the quality of fish produced abon. The results showed that fish species had a significant effect (P ? 0,01) on protein content, moisture content, fat content, ash content and color organoleptic value, and not significant (P> 0,05) to yield, the organoleptic value of texture, aroma, and flavor. The method of cooking fish meat was very significant (P ? 0,01) to protein content, fat content and not significant (P> 0,05) to yield, water content, ash content, the organoleptic value of texture, aroma, color, and flavor. The interaction between fish species and cooking method of fish meat had no significant effect (P> 0,05) on all parameters except on yield of abon fish produced.
