Abstract

Ikan kerapu cantang merupakan salah satu komoditas ekspor unggulan di Indonesia. Keberlanjutan budidaya ikan kerapu cantang perlu ditunjang dengan ketersediaan benih berkualitas. Upaya untuk menghasilkan benih ikan kerapu cantang dapat dilakukan dengan pemeliharaan larva dengan tepat. Penelitian ini bertujuan untuk mengetahui teknis pengelolaan pakan dan media air pada pemeliharaan larva ikan kerapu cantang. Jenis pakan yang digunakan berupa pakan alami dan pakan buatan dengan dosis yang disesuaikan dengan umur larva. Jenis pakan alami yang diberikan pada larva ikan kerapu cantang yaitu Nannochloropsis oculata, Rotifer, dan Artemia sp. Kisaran parameter kualitas air yaitu suhu 30,5-31 oC, pH 7,8-8,2, salinitas 33-34 ppt, serta DO 3,51-4,27 ppm masih optimal untuk pemeliharaan larva ikan kerapu cantang. Pengelolaan pakan dan kualitas air pemeliharaan larva dapat mendukung perkembangan larva ikan kerapu cantang dengan nilai Hatching Rate (HR) 48%-72% dan Survival Rate (SR) 16%-18%.

Abstract

The Pacific white shrimp (Penaeus vannamei) is a key species in global aquaculture, particularly under intensive farming systems where high stocking densities often lead to deteriorating water quality, disease outbreaks, and reliance on antibiotics. While probiotics are increasingly applied to enhance shrimp health and performance, comparative evidence on the efficacy of different commercial probiotic formulations remains limited. This study aimed to evaluate the effects of three commercial probiotic products on growth performance, water quality, microbial populations, and immune response in intensively reared Pacific white shrimp. Shrimp were fed diets supplemented with one of three probiotics (PB, PL, and PMB) or a control diet for 40 days. Growth parameters, nitrogenous waste levels, bacterial counts in water and organs, and total hemocyte count (THC) were analyzed. The PB treatment (multi-strain Bacillus) significantly enhanced specific growth rate (2.99±0.0027% day⁻¹), feed efficiency (57.5±0.09%), weight gain, and THC (3.80 × 10⁵ cells mm⁻³) compared to control (P<0.05). The PB and PMB treatments also reduced total ammonia nitrogen, nitrite, nitrate, and Vibrio populations in water and shrimp tissues. Intestinal colonization by beneficial bacteria was highest in PB and PL groups. These results demonstrate that specific probiotic formulations, particularly PB, can improve growth, immunity, and water quality while reducing reliance on antibiotics and water exchange. The findings support the integration of targeted probiotics in sustainable shrimp aquaculture, including biofloc and recirculating aquaculture systems (RAS).
