When it comes to small-scale fisheries, there is no one route to sustainability. Finding success stories can help map those paths.
Marine parks protect fragile ecosystems, like coral reefs.
What would you do if you saw a fisher breaking the law? Would you report the offender to the police? Confront them? Or would you do nothing? These choices affect the future of marine protected areas.

Mud oysters played a largely unappreciated part in Australia’s history.
In colonial times Australia's waters were teeming with mud oysters that provided food, cement, and cleaned the oceans. Now a 20-hectare man-made reef aims to restore some of their former glory.
The focus of food production systems, including aquaculture, must move beyond maximising yields to consider nutritional quality too.
Whitespotted surgeonfish (
Acanthurus guttatus), found in the Indo-Pacific, crop the upper portion of algae while feeding, preventing macroalgae from becoming established on reefs.
Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
