The incoming Director General of WorldFish, Dr Nigel Preston answered some questions prior to starting his role in December 2015.
Knowing whether aquaculture in developing countries helps the poorest in communities is an important question for development agencies who want to make pro-poor investments.
Historically, there have been two arguments that it does not.
First, to be a fish farmer you need to have a certain amount of wealth, so the poorest are unable to become producers. Second, aquaculture tends to produce larger, high-value fish that are too expensive for the poorest consumers.
