Using structured decision making to evaluate the tradeoffs of selective fish passage
Abstract Dams have dramatically altered rivers and are a major contributor to native fish population declines. However, many dams serve important ecological, social, and economic functions, such as flood control, invasive species control, and provision of recreational opportunities.

ABSTRACT Hatcheries and stocking programmes have long been a cornerstone of fisheries management, seen as tools for fisheries enhancement and/or conservation of threatened populations. Their use draws controversy, however, from a growing body of research over the last 50 years suggesting that stocking can have negative consequences for wild stocks, and

The Fish Behind Fish Feed: Rethinking Transparency Using DNA Tools
ABSTRACT Aquaculture is now the fastest growing food sector and may be a promising solution to increasing seafood demands. Yet, carnivorous aquaculture species such as salmon and seabass continue to rely on fishmeal and fish oil (FMFO), which are derived largely from pelagic fish that are sometimes key to the food security of some coastal nations.
