Overview

Case study reveals reduced mortality and improved metamorphosis in prawn hatcheries via human-guided AI support, highlighting the potential of collaborative intelligence in recirculating systems.

Key Points

  • To evaluate the feasibility and efficacy of using a large language model paired with human expertise as an interactive decision-support system in a giant freshwater prawn hatchery.
  • Conducted a 4-month observational case study in a Macrobrachium rosenbergii recirculating aquaculture system hatchery experiencing high larval mortality.
  • Engaged a large language model through structured, human-guided inquiry to analyze issues across chemical, biological, physical, engineering, and behavioral domains, implementing targeted adjustments.
  • AI-guided interventions—including mineral balance recalibration, microbial load diagnostics, behavioral pattern decoding, and lighting/flow engineering—qualitatively reduced larval mortality and improved metamorphosis rates to post-larvae (numerical values not reported).
  • Effective problem-solving depended on human experts to frame context and direct inquiries, preventing the artificial intelligence agent from oversimplifying complex aquaculture dynamics.
