Synopsis (short abstract) The global Pacific oyster aquaculture sector is plagued by a disease caused by the Ostreid herpesvirus, known in some countries as Pacific oyster mortality syndrome (POMS). POMS first arrived in Australasia in 2010 and caused massive mortalities, especially of young oysters, sometimes bringing about close to 100 percent mortality. At that time the Pacific oyster industries in Australia and New Zealand had already initiated genetic breeding programmes for commercially important growth-related traits. As POMS arrived in the region and started to spread throughout the two countries, these breeding programmes were able to pivot to breeding for POMS resistance, which turned out to be a highly heritable trait and responded very well to selection such that by 2018, selected oysters had average survival rates of around 80 percent during POMS outbreaks. This case study traces the development of oyster breeding programmes in Australia and New Zealand and describes how the industry sectors were able to respond quickly to the new and immediate threat of POMS and how the existence of ongoing breeding programmes, supported by both public and private sector, was critical to saving the industry from being completely decimated by POMS and how the breeding programmes enabled relatively rapid recovery from POMS-related losses. The study identifies the critical role of public–private partnership in the success of the breeding programmes and identifies some of the funding mechanisms that ensured ongoing success of these programmes.

Proactive approach proved key to survival for the Australasian Pacific oyster industry 2022

No results found.

Since 2008 Pacific Oyster Mortality Syndrome (POMS) has emerged as a significant threat to the Pacific oyster industry globally. The disease was first detected in Australia and New Zealand in 2010. The Australian industry is located in three states: New South Wales (NSW), Tasmania and South Australia, which produce up to 10 500 tonnes per year of Pacific oysters, Magallana gigas (previously classified as Crassostrea gigas). Hundreds of growers operate across the three states, using hatchery-reared spat as the basis for their production.

This study of the dairy value chain in the Oromia region of Ethiopia was conducted as part of the AgrInvest-Food Systems Project, a collaboration between the Food and Agriculture Organization of the United Nations (FAO) and the European Centre for Development Policy Management (ECDPM) to promote private investments in African food systems that contribute to local economic, social and environmental sustainability.

Stepping up – Everyone around the table for better nutrition and healthy diets
Step 3: Going to scale
2021

Also available in:

No results found.

This paper, STEP 3, is the third of three background papers produced to inform the ‘Everyone Around the Table: FAO/GAIN Roundtable with Private Sector on Healthy Diets’ series of virtual roundtables which took place in July 2020. As in STEP 1 and STEP 2, the topics covered are relevant to all regions, but where possible a greater focus has been given to low- and middle-income countries. Small and medium enterprises (SMEs) are again a focus, given their role in the food systems of these regions (see STEP 1 for more detail), including their common presence in the food environments of many people living in poverty. STEP 3 (this paper) looks more closely at what it means to go to scale with healthy diets and better nutrition, providing examples and reflections for all stakeholders to consider.
