Abstract

The optimization of nursery rearing techniques plays a crucial role in improving the survival rate and growth performance of cantang grouper (Epinephelinae). This study evaluates the effectiveness of a two-stage nursery rearing system at CV. Bali Akkua Marine, Bali, in enhancing production efficiency and economic feasibility. The results showed a consistently high survival rate of 95% across both phases. The reduction in stocking density in the second phase minimized stress and improved fish growth, while optimized water quality management, including filtration and flow-through systems, maintained stable environmental conditions. In addition, tailored feeding strategies incorporating vitamin C, probiotics, and Enrofloxacin 2S improved feed efficiency (FCR 1.3) and fish health. Economic analysis indicated that the system is highly feasible, with an R/C ratio of 3.48 and a break-even point far below actual production levels, demonstrating a high margin of safety. These findings highlight that the integration of optimized technical practices and efficient resource utilization can significantly enhance both production performance and economic sustainability in grouper nursery operations.

Author Biography

Putri Nurhanida Rizky, Teknik Budidaya Perikanan, Politeknik Kelautan dan Perikanan, Sidoarjo, Jawa Timur, Indonesia, 61254

I am an Assistant Professor at Departement of Aquaculture Engineering Politeknik Kelautan dan Perikanan Sidoarjo, specializing in aquaculture and fish health management. I hold a Master's degree from Universitas Brawijaya and National Pingtung University of Scienc and Technology, Taiwan. I have a strong academic foundation in biotechnology, applied immunology, and pathology, with a focus on sustainable aquaculture practices.

My research interests include:

  • Applied Immunology: Investigating immune responses in aquatic species to enhance disease resistance.
  • Pathology: Studying fish diseases and their management to improve health and productivity in aquaculture systems.
  • Sustainable Aquaculture: Developing practices that promote environmental sustainability while maximizing fish production.

I have contributed to various research projects, including studies on the growth performance of vannamei shrimp (Litopenaeus vannamei) and the impact of different aquaculture systems on fish health. My work has been published in several reputable journals, and I actively participate in community outreach programs to promote sustainable aquaculture practices.

In addition to my teaching and research responsibilities, I am committed to mentoring students and fostering a collaborative learning environment. I believe in integrating theoretical knowledge with practical experiences to prepare students for successful careers in the aquaculture industry.

Current Research Projects:

  • Comparative study of super-intensive vannamei shrimp farming with different oxygen saturation manipulations.
  • Analysis of spatial waste loads from intensive and traditional shrimp farming on aquatic environments.

I am dedicated to advancing the field of aquaculture through research, education, and community engagement.
