Secure sustainable seafood from developing countries

Demand for sustainably certified wild-caught fish and crustaceans is increasingly shaping global seafood markets. Retailers such as Walmart in the United States, Sainsbury's in the United Kingdom, and Carrefour in France, and processors such as Canadianbased High Liner Foods, have promised to source all fresh, frozen, farmed, and wild seafood from sustainable sources by 2015 (1, 2). Credible arbiters of certifications, such as the Marine Stewardship Council (MSC), require detailed environmental and traceability standards.

Integration of no-take marine reserves in the assessment of data-limited fisheries

No-take marine reserves show great promise as conservation tools, yet the integration of reserves into assessment models for data-limited fisheries management is just emerging. We develop a framework for integrating marine reserves into two data-limited assessment models: spawning potential ratio (SPR) and yield per recruit (YPR). We use Monte Carlo simulation to test the applicability of the framework to a sedentary species with a dispersive larval stage under process and observation uncertainties.

Significant and timely ivory trade restrictions in both China and the United States are critical to save elephants

The United States and China have committed to enact “nearly complete bans” on the import and export of elephant ivory, including putting in place significant and timely restrictions on the import of ivory as hunting trophies, and taking swift steps to halt their domestic ivory trade. Unlike the United States, China has to move forward on its commitment to further restrict its domestic commercial trade. This is primarily due to China's existing certificated ivory manufacturers and retailers who own huge legal ivory stockpiles.
