Abstract

Fish parasites represent a major part of aquatic biodiversity, and consequently affect the environment directly or indirectly through their hosts. The high prevalence of parasitic infections contributes to growth disorders and affects ecosystem dynamics. Parasites can manipulate host behavior, thereby increasing their vulnerability to predation.   A. thazard samples were obtained directly from Amed fishermen. The size of the tuna used ranged from to 20-30 cm/head, with a total of 30 fish. Samples were preserved in ice, placed in a cool box, and then brought to the Fisheries Science Laboratory, Faculty of Marine and Fisheries for parasitic worm examination. The results of this study, it can be concluded that the types of endoparasites found in this study:  Anisakis sp., Rhadinorhynchus sp., and Hemiurus sp., had prevalence values ranging from 18,3-26,6%, intensities ranging from 3.3-23.3 ind/fish, abundance values ranging from 0.61 to 5.8 ind, diversity indices ranging from 0.19 to 0.32 in the low category, and uniformity values ranging from 1,17 to 1.97 in the high category from 30 samples of Auxis thazard Lacepède, 1800 obtained from Amed.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh perbedaan kom posisi dasar terhadap kualitas air dan pertumbuhan ikan nila (Oreochromis niloticus). Penelitian ini dilakukan pada bulan November 2024. Metode yang digunakan adalah metode eksperimental dengan rancangan acak lengkap sebanyak 3 perlakuan dan 3 ulangan. Setiap perlakuan diberikan media filter yang berbeda yaitu perlakuan A (bio column)(kontrol), perlakuan B (bata), dan perlakuan C (bata + abu dasar genteng 10%). Hasil penelitian menunjukkan bahwa komposisi dasar filter memiliki pengaruh terhadap pengurangan amonia. Konsentrasi rata-rata amonia perlakuan A sebesar 0,979 mg/L; perlakuan B sebesar 1,078 mg/L; dan perlakuan C sebesar 0,779 mg/L. Suhu berkisar 27,5-27,6°C, oksigen terlarut berkisar 6,4-6,5 mg/L, pH berkisar 7,72-7,94, nitrit berkisar 0,010-0,011 mg/L, dan nitrat berkisar 0,548-0,560 mg/L. Hasil penelitian menunjukkan pengaruh tidak berbeda nyata (P>0,05) terhadap pertumbuhan, SGR, FCR, dan SR ikan nila. Rata-rata nilai berat mutlak perlakuan A sebesar 9,26 g, perlakuan B sebesar 8,17g, dan perlakuan C sebesar 7,72 g. Nilai SR diperoleh pada perlakuan A, B, dan C berurutan 86,7%; 86,7%; dan 93,3%.
