| description | ABSTRACT
This study aimed to determine optimum dissolved oxygen (DO) through the addition of aeration and to evaluate the role of dissolved oxygen on production performance and stress responses of mangrove crab Scylla serrata. Experimental design used was complete randomized design with four treatments namely no aeration (A), one point aeration (B), two points aeration (C), and three points aeration (D). All treatments replicated three times. The crab with the average of body weight 45.6±2.1 g/individual cultured in a plastic box (40×30×30 cm3). The stocking densities was 10 crab/box. Crab was cultured within 42 days and were fed two times a day by restricted method (15% of the total biomass). The result showed that C treatment produced 5.51 mg/L dissolved oxygen and gave the best result of mangrove crabs production performance with 60% survival, 0.83±0.03 g/day absolute growth rate and food conversion ratio 1.1. It also showed good response to the stress that indicated by the cortisol level (10.159 µg/dL). The best results of coefficient of diversity showed by D treatment that was 13.5%. The water quality during study period was fluctuative as affected by different dissolved oxygen value.

ABSTRAK
Penelitian ini bertujuan menentukan kadar oksigen terlarut (OT) atau dissolved oxygen (DO) yang optimum melalui penentuan titik aerasi serta mengevalusi peranan oksigen terlarut terhadap kinerja produksi dan respons stres kepiting bakau Scylla serrata. Rancangan penelitian yang digunakan adalah rancangan acak lengkap dengan empat pelakuan (penambahan titik aerasi dengan rincian A, tidak menggunakan titik aerasi; B, satu titik aerasi; C, dua titik aerasi dan D, tiga titik aerasi) dan tiga ulangan. Kepiting bakau yang digunakan memiliki berat rata-rata 45,6±2,1 g/ekor dengan padat tebar 10 ekor/wadah. Wadah yang digunakan selama pemeliharaan adalah bak fiber plastik yang berukuran 40×30×30 cm3. Pemeliharaan kepiting bakau dilaksanakan selama 42 hari dan diberikan pakan dua kali sehari dengan metode restricted yakni sebesar 15% dari biomassa kepiting. Hasil penelitian menunjukkan bahwa perlakuan C yaitu penambahan dua titik aerasi menghasilkan nilai kelarutan oksigen rata-rata sebesar 5,51 mg/L dan memberikan hasil terbaik terhadap kinerja produksi kepiting bakau (tingkat kelangsungan hidup 60%; laju pertumbuhan mutlak 0,83±0,03 g/hari; dan rasio konversi pakan 1,1). Perlakuan C juga menunjukkan respons stres yang baik dengan memiliki nilai kortisol paling rendah dari perlakuan lain yaitu 10,159 µg/dL. Untuk parameter koefisien keragaman berat, hasil terbaik terjadi pada perlakuan D sebesar 23,3%. Kualitas air selama penelitian memiliki nilai yang fluktuatif di setiap perlakuan sebagai efek adanya perbedaan nilai kelarutan oksigen yang dihasilkan.
