摘要

The increasing dependence on imported fishmeal and soybean meals has heightened the need for cost-effective and environmentally sustainable feed ingredients in freshwater lobster aquaculture. This study presents a comprehensive bibliometric and structured content analysis of research on local and alternative feed ingredients for Cherax spp. published between 1977 and 2025. A total of 55 Scopus-indexed publications were analyzed using VOSviewer (v1.6.20) and Biblioshiny to examine publication trends, keyword networks, thematic structures, and collaboration patterns. The results indicate a marked increase in research activity after 2017, reflecting growing global interest in sustainable aquafeeds. Four dominant thematic clusters were identified: (1) alternative protein sources and feed formulation, (2) growth performance and digestibility, (3) immunity, physiology, and antioxidant responses, and (4) sustainability and aquaculture systems. The content synthesis highlights that locally sourced ingredients, including plant-based materials, agro-industrial by-products, and insect-derived feeds, are frequently investigated as partial fishmeal substitutes across diverse experimental contexts. Rather than evaluating ingredient efficacy, this study provides a descriptive and integrative overview of research patterns, methodological characteristics, and emerging focus areas. Overall, the findings offer a structured reference for future research design and support evidence-informed exploration of sustainable feed resources for freshwater lobster aquaculture.
