Blue crabs (Callinectes sapidus) support a culturally and economically valuable commercial fishery in the Gulf of Mexico. Most states require the release of undersized and ovigerous blue crabs, yet mortality of these discarded crabs is an understudied and poorly estimated component of total mortality and represents a major data gap hindering effective management. The aim of this project is to quantify discard mortality of undersized and ovigerous crabs using bycatch surveys. Bycatch surveys have been conducted monthly aboard commercial crabbing boats in three locations across the Lake Pontchartrain-Mississippi Sound coastal system in Louisiana and Mississippi. Crabs were sexed and measured and the likelihood of mortality of a subset of crabs was estimated with a reflex action mortality predictor (RAMP) assessment. Throughout the project, conversations aboard commercial crabbing vessels serve as informal education sessions, which fosters trust with fishermen while empowering the research team to better understand the most pressing issues facing the fishery. The outcomes of this project will be used in the creation of crabber “best practices” and whiteboard videos to be shared through formal outreach avenues.
