An Issue in Honor of Yoram Avnimelech: Application of Biofloc Technology (BFT)

Dear Colleagues,

Yoram Avnimelech is an Israeli scientist and professor known for his pioneering work in aquaculture and environmental engineering, particularly in the development and advancement of biofloc technology (BFT). He has made significant contributions to sustainable aquaculture by promoting the use of microbial flocs to improve water quality and enhance fish and shrimp farming efficiency.

Professor Avnimelech played a key role in refining biofloc technology, which uses beneficial microbial communities to recycle waste (such as ammonia and organic matter) into microbial biomass, reducing the need for water exchanges and enhancing aquaculture sustainability. His research demonstrated that bioflocs serve as a natural protein-rich feed source for shrimp and fish, reducing the dependence on expensive commercial feeds. He has written influential books and research papers on biofloc systems, including the widely referenced book Biofloc Technology: A Practical Guide Book, which has helped farmers and researchers worldwide implement BFT. In addition, Professor Avnimelech provided several training courses across the globe, and his work has inspired large-scale the adoption of biofloc technology in countries such as India, Indonesia, Vietnam, China, Brazil, and Ecuador, significantly improving sustainable shrimp and fish farming.

To conclude, we would like to share a few words from Dr. Yoram: "I am convinced that Biofloc Technology contributes to aquaculture production, minimizes diseases outbreaks, improves farmers’ viability and helps to preserve the environment. However, we need to improve and expand the training of farmers and maintain a dialog with the industry so as to produce more suitable feeds and equipment adaptable to BFT (especially aerators). I will be happy to help".  

In recognition of Dr. Yoram Avnimelech's exceptional research throughout his distinguished career, we aim to create a Special Issue to invite contributions from scholars, collaborators, and friends across the diverse fields where he has made significant contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fishes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
