Saltwater · Year-round; best spring to early autumn, young born in summer
Tule Perch
Hysterocarpus traski
The tule perch is the only fully freshwater surfperch — a true surfperch that lives its whole life in the Sacramento-San Joaquin system and Clear Lake, far from the sea. Like its saltwater cousins it gives live birth, with fully formed young born in summer.

Rig: Light float rig with a size 12-14 hook and insect bait, drifted slowly along reed margins in slow rivers
