During the temporary, smolt generation could boost by switching hatchery and stocking procedures. By way of example, scientists could target habitats that do not at the moment have any salmon. This could certainly enable offset the populace lessen due to ongoing threats, but has restricted capability to absolutely Recuperate imperiled salmon populations.

Analyzing the volume of salmon from the Gulf of Maine DPS—and whether or not the population is rising or reducing as time passes—helps source managers evaluate the successes and failures of enacted conservation measures and really helps to guide future recovery actions. Our scientists accumulate information and facts and current these facts in annual stock assessment experiences.

The effects will offer a snapshot of surface water temperatures within the river. Scientists are especially centered on chilly-water patches that offer refuges for migratory fish since they shift up and down the river. Climate improve could end in much less, hotter cold-water refuges.
