This technical manual provides practical guidance on the hatchery production of the flathead grey mullet, Mugil cephalus, a high-value, low-trophic marine species with strong potential for sustainable aquaculture development. It compiles current knowledge and tested methodologies covering the entire production cycle, from broodstock management and captive reproduction to larval rearing, fry production and grow-out.

The manual presents the biological and developmental characteristics of the species, together with practical recommendations for hatchery site selection, design and operational management. It also describes live feed production, including microalgae, rotifers and Artemia, as well as health management and disease prevention in hatchery systems.

Based on experimental research validated at laboratory and pilot scales, the techniques described are suitable for application in commercial hatcheries and adaptable to both small- and large-scale operations. By supporting reliable seed production and improved culture practices, this publication contributes to the sustainable expansion of aquaculture in line with the FAO Blue Transformation Roadmap and the principles of the Guidelines for Sustainable Aquaculture.

Circular nutrition in aquaculture focuses on reducing waste and closing nutrient loops by transforming fish byproducts into sustainable aquafeed. Simon Das from the Tropical Aquafeed Innovations Lab at James Cook University presents how this model can cut reliance on wild-caught forage fish while supporting cost-effective, nutritionally balanced diets. The lab’s work includes developing weaning protocols for pellet-ready fingerlings, training farmers in advanced feeding practices and economics, and promoting gender and youth inclusion. Circular nutrition highlights how rethinking resource use can make aquaculture both more efficient and more sustainable.

This report covers the fourth quarter of 2024 and the original and updated reports can be accessed from the QAAD page.

The project conducted a preliminary survey of the effectiveness of various types of nature-based solution (NbS) in use in the Philippines that contribute to climate change resilience by enabling off-grid farm operations and reducing reliance on costly fossil fuels, renewable materials and improved designs that enhance efficiency. Aquaculture enterprises were assessed for this project based on the NbS they utilised and the potential benefits they offer in mitigating climate change impacts and enhancing production systems.

Based on BFAR Regional Field Office Submissions, 50 aquaculture innovations nationwide have been identified to date. The list will be extended and screened as further regions report, in cooperation with the BFAR National Research Centers.

This report summarises the proceedings of the 23rd meeting of the Regional Advisory Group on Aquatic Animal Health, held 14-15 November 2024 by video conference. The role of the group is to review trends in disease and emerging threats in the region, identify developments in global disease issues and standards, to evaluate the Quarterly Aquatic Animal Disease Reporting Program and to provide guidance on regional strategies to improve aquatic animal health management.

The 14th Asian Fisheries and Aquaculture Forum (14AFAF) will be held from 12-15 February 2025 in New Delhi, India. Submission of abstracts has been extended until 5 November, and early bird registration closes on 10 November, so get in quick!

The forum is a scientific meeting organised by the Asian Fisheries Society (AFS) once every three years to understand the global trends and address issues and challenges faced by the fisheries and aquaculture sector. The main purpose of this Forum is to provide an international platform for eminent scientists, young researchers, and other stakeholders across the globe to share their research experiences and innovative ideas. By facilitating the exchange of diverse range of knowledge and expertise, the Forum with the Theme ‘Greening the Blue Growth in Asia-Pacific’ aims to address key issues towards developing sustainable fisheries and aquaculture.

Presentation on opportunities to transform Fijian aquaculture: Challenges, innovative technologies, and nature-based solutions, by Chinthaka Hewavitharane (Pacific Community), Tekata Taoisi and Prashneel Chandra (Ministry of Fisheries, Fiji). Presented at the Inception Workshop for the project "Knowledge brokering for nature-based solutions in aquaculture transformation in Asia-Pacific: Support to the Aquaculture Innovation and Investment Hub", 4-5 June 2024, Bangkok.

With the implementation of the new aquatic animal disease reporting in the Asia Pacific region from January 2021, and in lieu of the published QAAD Reports (last issue published was 4^th quarter of 2020), NACA is publishing reported aquatic animal diseases submitted by countries in the Asia-Pacific region. This report covers the first quarter of 2024 and the original and updated reports can be accessed from the QAAD page.

Canada's International Development Research Centre (IDRC) is sponsoring the project "Knowledge Brokering for Nature-Based Solutions in Aquaculture Transformation in Asia-Pacific: Support to the Aquaculture Innovation and Investment Hub." The project is part of a wider IDRC AQUADAPT initiative, a four-year partnership running from 2023-2027. AQUADAPT addresses the intertwined challenges of climate change, biodiversity loss, and food insecurity through applied research on nature-based solutions in aquaculture in Southeast Asia and the Pacific region. AQUADAPT emphasises Gender Equality and Social Inclusion (GESI), ensuring that nature-based solutions are inclusive of all genders and marginalised groups. The project's inception workshop was held in Bangkok from July 4-5, bringing together project teams from Thailand, The Philippines, and Fiji to discuss approaches and methodologies. 

This event, held jointly via Zoom or in person at FAO Headquarters in Rome, will bring together leading experts to delve into the topic of fish vaccination and new developments regarding shrimp vaccination as a vital biosecurity strategy. Current knowledge will be reviewed, examining obstacles, and uncovering opportunities for vaccine development. Bridging theory with actionable practice, the seminar aims to foster informed decision-making, discussing the potential of vaccination and addressing associated challenges. Building upon the success of the Tilapia Health webinar held in December 2021 and Tilapia health: quo vadis, this conference will be a continuation of impactful discussions, promising a dynamic and enriching experience for all participants.
