Eight thematic reviews prepared as preparation for the Global Conference on Aquaculture Millennium +20 (GCA +20) have been published in a Special Issue of the Journal of the World Aquaculture Society "Aquaculture for Food and Sustainable Development". A group of experts prepared advanced working drafts of each thematic review and the key findings from each theme were presented and discussed by expert panels during the GCA +20. Participants were then invited to provide their feedback and perspectives on the reviews and their key messages for consideration in finalisation of the papers. The reviews are available for free download.

CAA7 will be held in Hainan, China, from 29 November to 2 December, with an option for online participation via Zoom for people that cannot attend in person. The theme of the symposium is "Sustainable development of cage aquaculture in Asia". Sessions will be held on: Production systems; breeding and seed production; nutrition and feed; carbon sink and fouling organisms; health and environmental management; economics, gender, livelihood and policy.

The symposium is organised by the Asian Fisheries Society, Hainan University, Shanghai Ocean University, and the China-ASEAN "Belt and Road" Joint Laboratory of Mariculture Technology, Center for Ecological Aquaculture.

Natural feeds present in ponds contribute to some extent to the nutrition of fish cultured therein. But these natural food stocks become insufficient as production intensity rises. In semi-intensive and intensive systems, nutritional inputs must be partly or wholly supplemented using external feeds to support higher growth and productivity. Good quality feed is essential to achieve higher production. The selection of proper feedstuff and good formulation to meet the requirements of the cultured species will enhance acceptance and utilisation. This article discusses feed preparation, ration size, feeding rate, feed distribution and feeding schedules for culture of Indian catfishes.

The 2023 Shrimp Summit will convene the global seafood value chain to address the critical challlenges of Asia’s shrimp-farming sector, from stagnant production to growers’ livelihoods, with a cross-topic focus on sustainability and climate change. The Summit is presented by The Center for Responsible Seafood (TCRS) and co-hosted by the Global Seafood Alliance. The format of the 2023 Shrimp Summit will allow the industry to develop a common understanding of issues, address key challenges through discussion and work toward consensus and actionable solutions. This in-person and virtual event will feature discussions, relevant content and informative webinars before, during and after the event in the TCRS Online Community. Access to the online community is included with event registration.

The 13th APMBC and 5th ANZMBS conference are combining to engage marine biotechnologists, industry, investors, and policy makers in current marine biotechnology research, and industry development in the Asia-Pacific region. The conference will be held from 2-6 October 2023 in Adelaide, Australia. This provides a great opportunity to participate in the growth and future development of the marine biotechnology industry in the region and globally. A key objective of the joint Conference is to encourage academic-industry partnerships across the region. Abstract submissions and early bird registrations are now open!

The yellow tail catfish Pangasius pangasius is found throughout the rivers of the Indian subcontinent. A large, omnivorous, and highly fecund species, it is suitable for aquaculture. Initial work on captive breeding of yellow tail catfish was carried out by scientists from the ICAR-Central Institute of Freshwater Aquaculture in the early 1990's. This article provides updated information on captive reproduction, larval rearing and nusery techniques for this species, which will be of use for farmers and entrepreneurs interested in producing it.

Ocean University of China and partners will convene the forum from 20 to 22 November 2022. The forum will cover the following: Topic 1: International talent cultivation and training;Topic 2: Science and technology innovation; Topic 3: Industrial synergy. The forum will host discussions about the implementation of the “Blue Transformation” strategy, further expansion of the space for fisheries and aquaculture, and ways of improving the production capacity of aquatic products, with the purpose of facilitating the achievement of the UN Sustainable Development Goals. Participation is free but registration is required. Registration closes on 22 October.
