Fish Feel Water Movement

This sensory system helps fish notice nearby movement even when visibility is poor.

Smell Can Be Powerful

Salmon can use chemical cues when returning toward their home waters, while catfish rely heavily on taste and smell.

Temperature Changes Behavior

Metabolism, feeding, oxygen demand, and movement often change with temperature.

Fish Migrate Far

Salmon connect rivers with oceans, tuna cross ocean basins, and striped bass migrate along coastlines.

Sonar Sees Underwater

It can estimate depth, bottom shape, submerged structure, and objects in the water column.

Fish Can Live a Long Time

Age can sometimes be estimated from growth rings in otoliths, scales, spines, or other hard structures.

Rules Are Part of Fishing

They respond to population size, reproduction, habitat, fishing pressure, and conservation goals.

Every Catch Comes From an Ecosystem

Protecting aquatic insects, wetlands, vegetation, clean water, prey fish, and spawning areas helps support the species anglers value.
