Abstract

This systematic review evaluated sustainable preservation methods for transporting fresh fish between 2020-2025, with a focus on efficacy, sustainability, and feasibility in tropical climates. Following PRISMA guidelines and the PICOC strategy, thirty peer-reviewed articles from Scopus and SciELO were analyzed. Findings showed that emerging technologies—including solar-powered refrigeration, edible coatings, and modified atmosphere packaging (MAP)—outperformed conventional ice-based preservation in extending shelf life and reducing environmental impact. Solar refrigeration operated at 85.6% efficiency, chitosan-based coatings preserved freshness for up to 16 days, and MAP helped slow down spoilage. In contrast, ice-based methods were energy intensive and carbon heavy. Overall, sustainable approaches improved fish quality, safety, and cost-effectiveness while mitigating CO₂ emissions. The review concludes that adapting these technologies to tropical conditions, where cold chains are insufficient, is essential to ensure reliable fish preservation, enhancing food security, and supporting climate goals.
