Inside the Industry

NMFS recently released a draft action plan for fish discard and release mortality science, creating a list of actions that they hope can better inform fisheries.

We know that fishermen have to deal with bycatch by discarding or releasing unwanted catch overboard, but there is a data gap regarding how those fish survive.


A new study has identified a set of features common to all ocean ecosystems that provide a visual diagnosis of the health of the underwater environment coastal communities rely on.

Together, the features detail cumulative effects of threats -- such as overfishing, pollution, and invasive species,  allowing responders to act faster to increase ocean resiliency and sustainability.
