Dive Summary:

• Many industry and retail sources have realized that the move towards environmental consciousness and sustainability has not been universal, with seafood being one of the most neglected areas.
• In response to this, retailers have begun extensive campaigns to educate the consumer on proper fishery management and other population-sustaining measures that the fishing industry is taking in order to preserve the world's global supply of seafood.
• They are achieving this mostly at the point-of-sale, with information laden signs and brochures that elegantly describe the issues as well as the solutions being taken by certain fisheries, measures that seem to be having a positive effect.  

From the article:

Unlike so many food industry issues, maintaining sustainability of our seafood supply has not been a major concern of consumers, many retailers and industry sources agree. Naturally, consumers want their favorite seafood available now, but they’re not, for the most part, thinking about what’ll be available in the future.
The nitty gritty of everyday retailing is dependent on sustainability of all the seafood species popular with consumers, and that’s why retailers are taking measures to educate their shoppers about how sustainability directly benefits them.
