A bibliometric approach to understanding the recent development of self-sufficient fish feed production utilizing agri-food wastes and by-products towards sustainable aquaculture

The global agri-food industry generates a large volume of waste annually, which causes both environmental and economic problems. Recently, there has been a growing interest in the use of agri-food wastes and by-products to produce self-sufficient fish feed. This study aimed to analyze the intellectual structure of the recent research on the utilization of agri-food wastes and by-products as self-sufficient fish feed materials based on 922 Scopus-indexed core collection documents from 252 journals written by 4420 authors from 73 countries with an annual growth rate of 18.65% over the last four years (2019-2022). This bibliometric study implemented knowledge domain visualization (KDV) using VOSViewer and Biblioshiny in the Bibliometrix R-package to investigate the basic scientometric profile of the selected fields. The results showed that Dawood M.A.O., with PageRanks of 0.0732, 19 total publications, 695 global citations from 2019 to 2022, and closeness values of 0.25, was the most productive author within the field. Subsequently, China was determined to be the most productive country (93 valid documents) and have the strongest collaboration network. Major research hotspots in the field included aquaculture and sustainable aquaculture, fish feed with agri-food waste, rainbow trout species, the development of a circular economy, probiotic applications, and cell signaling cytokines and peptides. This bibliometric study provides comprehensive information on the intellectual domain and research landscape on self-sufficient fish feed and also shows how interest in this research topic and similar ones is growing.

PENEBARAN IKAN BANDENG DI WADUK JATILUHUR: Analisis Dampak dan Kebijakan Pengembangan

Penebaran ikan bandeng merupakan salah satu opsi pengelolaan yang dilakukan untuk memperbaiki kualitas perairan yang semakin menurun di Waduk Jatiluhur. Penebaran ikan bandeng ke perairan waduk Jatiluhur secara sistematis telah dilakukan sejak tahun 2008, namun demikian, manfaat yang dapat dirasakan belum banyak mendapat perhatian. Penelitian bertujuan untuk mengevaluasi secara sosial ekonomi dampak penebaran ikan bandeng di perairan Waduk Jatiluhur sebagai basis pengembangan di masa mendatang telah dilakukan. Penelitian di lapang menunjukkan bahwa penebaran bandeng memberikan dampak bagi kualitas sumberdaya perairan serta kondisi sosial ekonomi masyarakat. Berdasarkan pertimbangan-pertimbangan tersebut maka beberapa rumusan kebijakan yang perlu ditindak lanjuti adalah: (i) mengkaji dampak penebaran ikan bandeng terhadap pertumbuhan ikan budidaya dalam karamba; (ii) melakukan ujicoba penebaran dengan jenis ikan lainnya yang mampu bereproduksi secara alamiah di perairan waduk dan tidak menganggu kestabilan dinamika populasi ikan; (iii) penguatan kelembagaan penebaran ikan, serta; (iv) melakukan sosialisasi lebih intensif mengenai perlunya kesadaran masyarakat untuk menjaga kelestarian sumber daya perairan.Title: Introducing Milkfish in the Jatiluhur Reservoir: Analysis of Impacts and Policies Development.Introducing milkfish is considered one of management options to improve water quality in the Jatiluhur reservoir. This activity has been systematically carried out since 2008; however, tangible benefits from this activity are less coverage. This research aimed to evaluate socio-economic impacts of milkfish stocking in the Jatiluhur reservoir that can be used as a basis for future fisheries development in this reservoir. Results of this research show that milkfish-stocking in the Jatiluhur reservoir contributed to the improvement of its aquatic resources environment and socio-economic conditions of the society. Based on these findings, several policies recommendation should be followed up and implemented, namely (i) immediately assess the impact of milkfish stocking to the growth of fish cultured in the cage; (ii) stocking different fish species that enable to reproduce naturally in the reservoir waters without disturbing population dynamic of fish stock; (iii) strengthening institution of the fish stocking program, and (iv) intensify dissemination and people awareness to conserve aquatic resources.
