TREND EVALUATION ON WASTE PRODUCTS AS POTENTIAL ALTERNATIVES FOR FISH FEED: A BIBLIOMETRIC ANALYSIS

Abstract

Due to the need for sustainable and cost-effective aquaculture feed solutions, waste products are being studied as fish feed alternatives. Moreover, considering the environmental concerns and the depletion of fishmeal resources, agricultural residues, industrial by-products, and organic waste are being investigated as feed ingredients. Scopus and VOSviewer data will be employed to assess this emerging field's research trends, key contributors, and collaborative networks, as well as to map keyword and co-authorship networks in 1,236 publications from 2014 to 2024. A significant increase in publications occurred after 2017, with the highest research output between 2021 and 2023. China, Indonesia, and the United States (US) lead in publications and citations, indicating a global focus on sustainable aquaculture. The analysis also highlights keywords like "animal feed," "waste management," "biomass," and "sustainability," indicating a strong focus on waste product valorisation for feed quality. The findings reveal international collaboration and a multidisciplinary approach integrating environmental science, agricultural technology, and nutritional evaluation. Due to resource efficiency and environmental sustainability, waste-derived feed alternatives are becoming more popular. This study sheds light on current research, suggests future directions, and emphasises the need for innovation in waste-based feed solutions for aquaculture.
