Anadromous fishes are commonly thought to use inland waters for spawning and for rearing in the first growing season.

Thereafter, they emigrate seaward to feed, grow, and mature. However, yearling (age 1+) alosine herrings have been observed in the Hudson River estuary during the spawning season. We quantified the frequency of this behavior for Blueback Herring (Alosa.

LOW LIGHT. There is general agreement among seasoned salmon anglers that springers move at first light and that there is a huge advantage to being on the water at dawn.

Too much bright light can make springers skittish and cause them to move to deeper water when the sun is high overhead, as Rick Estes of Adriatic Outfitters can attest.

Species that find their prey visually, such as salmon, forage fish, and Dungeness crab, may have an impaired ability to find food in low light conditions The contrast between light and dark areas can also change fish behaviors and movements related to schooling, migration, and feeding, potentially increasing exposure to predat encounter during their upstream migration in the Columbia River) in – and computed catch per unit effort This is not surprising in light of the fact that lamprey are Low Light as a Possible Impediment to River Herring Migration.
