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.

Collectively carps represent the largest global aquaculture sector, contributing over 20 percent of global aquaculture production. The Indian major carps including catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirhinnus mrigala) are cultured widely across the Indian sub-continent with the main culture system being a multi-species polyculture in ponds, often including other carp species. This production sector is supported by major seed supply systems producing over 50 billion seed per annum. This case study analyses genetic management of Indian major carps since they were first domesticated with the development of hypophysation techniques in the 1950s. A review of literature and a survey of common hatchery practices identifies significant problems prevalent in the sector brought about by a lack of application of best practices in genetic management resulting in loss of genetic diversity, inbreeding and uncontrolled hybrid introgression.

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!

Update: The forum will now be held on 13 December and and updated conference agenda is available below. Please register your attendance using the form linked below. A Zoom link will be sent to all registered participants before the meeting, thank you.

A free online forum will be organised by the Agriculture Trade Promotion Center, Ministry of Agriculture and Rural Affairs of the People’s Republic of China, and Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, and NACA. The forum aims to strengthen international exchange and cooperation in aquatic trade, promote high-quality development of fisheries, disseminate advanced concepts, technologies, and models of aquaculture in the Asia-Pacific region and Silk Road countries, and promote the health and sustainable development of global fisheries. Participation is free but registration is required.

Establishing recreational fisheries in Uttarakhand's highland lakes and river systems offers new opportunities to generate livelihoods and income for hill people. The development of catch-and-release sport fisheries can also contribute to conservation of aquatic biodiversity through development of captive breeding technologies, supportive breeding based stock enhancement, and community participation in management of both fishery and habitat. This article describes established and emerging sport fisheries in the highlands of Uttarakhand including for mahseer, goonch and brown trout. It also addresses as yet unrealised opportunities for establishment of recreational fisheries identified through geoinformatic approaches, and partnerships between local communities and government in natural resource management.

The conference will be held in virtual format. Please download the flyer below or visit the conference website.

Climbing perch Anabas testudineus is a high-priced fish, nutritious and economically profitable for small- to medium-scale fish farmers, who can obtain fry from local paddy fields and low-lying inundated areas in late summer, monsoon and post-monsoon periods. Climbing perch is a facultative air-breathing fish that is able to move between water bodies by undertaking short migrations overland. This article describes techniques for climbing perch and major carp aquaculture, including use of biofloc systems, preparation of live feeds including mealworms, and some concerns regarding the hybridisation of native Indian strain of A. testudineus with an imported Vietnamese strain.
