Abstract

Ikan bandeng (Chanos chanos) merupakan komoditas hasil budidaya perairan payau yang bernilai ekonomis tinggi bagi masyarakat pesisir, termasuk di Gampong Kapa, Kota Langsa. Penelitian ini bertujuan mengidentifikasi jenis ektoparasit serta menganalisis prevalensi, intensitas, dan dominansinya pada ikan bandeng yang dibudidayakan di tambak Gampong Kapa. Penelitian dilakukan pada Oktober-november 2025 di tiga tambak tradisional menggunakan metode survei dengan teknik stratified random sampling. Sebanyak 46 ekor ikan bandeng diperiksa menggunakan metode scraping pada lendir, sirip, dan insang, kemudian diidentifikasi secara morfologi menggunakan mikroskop. Hasil penelitian menunjukkan empat jenis ektoparasit yaitu Unitubulotestis sp., Dactylogyrus sp., Cryptocaryon irritans, dan Benedenia sp. Prevalensi tertinggi terdapat pada Unitubulotestis sp. sebesar 21,73%, dengan intensitas infeksi rendah dan dominansi tertinggi sebesar 69,56%. Kualitas air berada pada rentang yang optimal untuk budidaya ikan bandeng sehingga tingkat infeksi ektoparasit tergolong rendah dan belum membahayakan secara serius.

Abstract

Recirculating Aquaculture Systems (RAS) are an important innovation in the development of sustainable aquaculture, enabling the management of high stocking densities in controlled environments. This study aimed to evaluate the effect of different stocking densities of grouper (Epinephelus coioides) seedlings on growth performance, feed efficiency, survival rate, and water quality in a RAS. In this study, grouper juveniles (9.4 ± 0.54 cm and 14.22 ± 0.67 g) were reared in 100-liter aquaria and cultured for 70 days. The experiment was arranged in a Completely Randomized Design (CRD) with three stocking density treatments (15, 20, and 25 fish/aquarium), each with three replicates. Observed parameters included total length, total weight, Weight Gain (WG), Specific Growth Rate (SGR), condition factor (K), Feed Intake (FI), Feed Conversion Ratio (FCR), Feed Efficiency Ratio (FER), water quality (salinity, dissolved oxygen, temperature, pH), and Survival Rate. The results showed that increasing the stocking density up to 25% produced the best growth performance and feed efficiency (WG 574%, SGR 2.72%/day, FCR 1.32, FER 0.76) without reducing the survival rate (SR 100%). Water quality remained within optimal ranges, although slight decreases in dissolved oxygen and pH were observed. Therefore, the RAS was proven to effectively and sustainably support high-density grouper aquaculture.
