Fishery Stock Assessments at the NEFSC

Fishery stock assessments provide the scientific basis for ensuring sustainable fishery harvests. Assessment scientists use a variety of information about harvested stocks to model the population’s vital statistics: the number of individuals, their ages, and reproductive success, for example. From this information they can estimate current and future stock condition under different harvest rates. They can increasingly account for environmental effects such as ocean warming, a major new feature in the waters we study. In the Northeast, our center manages assessment development, review, and reporting, and involve federal, state, academic, and other scientists in the process.
