Status of Marine Resource
Rate your response to the following question, and your level of certainty, using the indicators below and the methods to the left.
What is the abundance or biomass of exploited species relative to management targets aimed at optimizing biological productivity, economic performance, ecological functionality, social equitability, or other goals?
B/Bmsy (or another target)
Density of biomass in a well-managed MPA (as compared to outside the MPA) that contains habitat types similar to those outside the MPA, can sometimes serve as a proxy.
Have you noticed a change in the species (e.g., types, amounts, or sizes) in the area?
Are fishers no longer able to find a certain species they used to catch regularly?
Are individuals getting smaller?
Have any “charismatic” species become less abundant or disappeared?
B >= Bmsy (or other proxy)
Bmsy > B > 50% Bmsy (or other proxy)
B < 50% Bmsy (or other proxy)
