In this issue:

The 15th meeting of the Asia Regional Advisory Group on Aquatic Animal Health; a regional consultation on responsible production and use of feed in aquaculture; a report on the Giant Prawn 2017 conference; a preview of the new NACA website; and new initiatives on a very serious emerging issue - reducing the human and animal health risks from development of anti-microbial resistance in the aquaculture industry.

Giant Prawn 2017

The fourth major international event on giant freshwater prawns was organised by the Asian Institute of Technology from 20-24 March 2007. The conference, organised by Salin Krishna and Michael New, built on a series of highly successful events that trace back to the very beginnings of the industry. The first conference, Giant Prawn 1980 brought together all those involved in freshwater prawn research and farming for the first time and set many priorities for future research and development.

Practical significance of restricted feeding regime in aquaculture

Feed is the most expensive component of an aquaculture enterprise. Successful cultured fish production requires optimisation of feeding practices to ensure the most economically effective growth rates. Reducing feed costs for culture practices can be achieved by taking the advantage of restricted feeding strategies. Under a restricted feeding regime fish convert a greater portion of feed to body weight. Case studies of restricted feeding are presented for several species and the costs savings and other benefits are briefly discussed.

Regional consultation on responsible production and use of feeds in aquaculture

FAO, NACA and the Thai Department of Fisheries convened a Regional Consultation Responsible Production and Use of Feed and Feed Ingredients for Sustainable Growth of Aquaculture in Asia-Pacific in Bangkok, 7-9 March 2017. The objective of the consultation was to review the current status of aquaculture feed production and use, demand and supply, sourcing of ingredients, government policies and institutional support, ongoing progress and development gaps. The meeting brought together government and private sector representatives.

Certification of fishmeal and fish oil in aquaculture feed production and utilisation

Due to the recent increase in aquaculture and the rising demand for marine ingredients for use in pelleted feeds, there is concern that aquaculture is contributing to the over-exploitation of fishing stocks. There is a growing need for aquaculture enterprises to be able to demonstrate responsible practices, including the source of any marine ingredients used in the compound feed. Responsible sourcing can be demonstrated by purchashing ingredients that have been approved under the IFFO RS standard.

Thai Union: Efforts of private sector feed manufacturers supporting sustainable aquaculture development

Thai Union Feedmill's initiatives to address sustainability issues in aquaculture feed ingredients are discussed in this presentation.

CPF's approaches and experience in developing sustainable fishmeal supply chain

Over the years, there have been two growing sustainability concerns with shrimp supply chain, namely human trafficking and environmental impacts. Solving these two issues can sometime result in conflicting agendas. This summary outlines CPF’s approach and experience in dealing with the two issues. The most difficult challenge in our experience is in building trust and understanding between the stakeholders, including governments and regulators, fisherfolk, commercial fishermen, suppliers and buyers. However, we feel that CPF is now a pioneer in our programs.

Government policy and enabling environment supporting and managing aquaculture feed production and marketing for sustainable aquaculture development in Thailand

The Department of Fisheries is responsible for aquaculture sustainability, including food safety, animal health and welfare, environmental integrity, social and community welfare and regulation of fishing activities across the whole aquaculture supply chain. The Feed Quality Control and Development Division is responsible for registration and certification of feed formulas and monitoring of feed quality. In addition to input controls, end products are also subject to inspection and monitoring, certification and traceability systems.

Government policy and enabling environment supporting and managing aquaculture feed production and marketing for sustainable aquaculture development in China

China is the world's largest producer of aquaculture feeds. With the development of aquaculture, the feed industry has inevitably faced some challenges in promoting update of commercial feeds, pollution, use of trash fish, fish meal and fish oil issues, provision of accurate nutrition and feeding, antibiotic residues, food safety, and so on. In order to balance economic and environmental issues the Chinese Government released its 13th Five-year Plan last year. Trends and policy changes relevant to aquaculture are discussed.
