A conservation lens
Estuaries are vulnerable to shoreline loss, polluted runoff, dredging, and barriers between nursery and adult habitat.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
