Largemouth Bass

Micropterus nigricans

The freshwater fish LA anglers actually chase. Florida-strain genes and a long local tournament history, especially at Castaic.

Year-round, best spring/fall
Difficulty

Habitat around Los Angeles

Weed lines, docks, timber, and drop-offs in reservoirs — Castaic, Pyramid, Puddingstone, and many urban lakes.

How LA anglers actually fish them

Statewide lakes: 12-inch minimum, five fish (T14 CCR §5.00). Castaic Lake is a listed special-regulation water: 15-inch minimum, five fish. Castaic own recreation guide still posts 15 inches. CDFW has discussed aligning Castaic with the 12-inch statewide rule — confirm §5.00 before you keep a 13-inch fish there. Pyramid and Puddingstone follow the 12-inch statewide lake rule unless posted otherwise.

Current CDFW regulations

  • Size limit: Statewide lakes 12 inches; Castaic Lake 15 inches (special regulation in §5.00 as published)
  • Bag / possession: 5 black bass
  • Season: All year on lakes

Confirm Castaic before keeping a fish between 12 and 15 inches. Castaic Lagoon is a different basin — check on-site posting.
