Studies on fishmeal substitution have been conducted on many aquaculture species and publications indicate that some can be grown on fishmeal-free feeds with amino acid supplements. Quantities of fishmeal and fish oil in feed formulations have been substantially reduced and it appears that inclusion levels can be further reduced without sacrificing growth performance and utilisation of nutrients. The potential to utilise alternatives to fishmeal and fish oil in aquaculture diets is reviewed and issues and gaps identified.

In this analysis the maximum and minimal amounts of feed required to produce finfish and shrimp in the region has been estimated. Globally a great deal of effort and time have been spent on issues related to fish meal and fish oil and aquafeeds. Ongoing practices thought to result in inefficient use of feed resources are highlighted and improvements shown. Information on feed usage in aquaculture in a few nations in the region are discussed and emerging issues highlighted.

It is estimated that around 1,061,173. tonnes of commercial aquaculture feeds were consumed on 2016. The aquaculture feed milling industry in the Philippines is presently  over capacity, based on the above-estimated feed requirement. The current primary law on animal feeds, which also covers aquaculture feeds, is under legislative review. Animal feeds ingredients standards are defined under administrative orders. Quality standards for finished aquaculture feeds are specified under the Philippine National Standards on Aquaculture Feeds (PNS/BAFPS 84: 2010).

This presentation gives an overview of aquaculture feed production and related issues in Vietnam.

Approximately 90% of aquaculture produce in Thailand are fed with a complete commercial feed. The Department of Fisheries is responsible for the licensing and registration of feed to be sold for commercial purposes. High quality fishmeal is a priority for aquaculture feed production especially for shrimp and marine fish and this has significantly affected feed cost. Most agricultural by-products are already utilised for purposes such as livestock, pet foods, fertilisers and biofuels, so competition for alternative ingredients is high.
