This special issue of Aquaculture Economics & Management features five articles based on contributions to the International Association of Aquaculture Economics & Management (IAAEM) sponsored section on economics and marketing at the World Aquaculture Conference in New Orleans, Louisiana, February 19-22, 2015. The IAAEM session was conducted over 2 days with 36 presentations in the program. The presentations highlight the increased importance of aquaculture, as production and trade are expected to continue to increase. That implies that there are economic decisions to be made at all stages in the supply chain from input providers, in production, in the supply chain, and in addressing consumer preferences. This is largely reflected by the variety of topics addressed in this special issue. Although five articles in this special issue can never represent the full extent of topics and species that were covered in all presentations, they provide a fair indication of the variation when it comes to topics, but less so when it comes to species. It is worthwhile noting that, although there is an increasing focus on markets and demand, the special issue does not quite do justice to the many interesting contributions on the production side. It is also interesting to note how a number of the topics build on what was presented at Aquaculture Americas 2013 and 2014.
