As surface temperatures increase in the summer, hybrids move deeper into cooler water.

During spring and fall, find hybrid bass off shore over deeper water, but actively feeding in the top 5 to 15 feet. The temperature of the reservoir is moderated by a large deep-water inflow of constant-temperature springwater so that hybrids feed actively and can be caught throughout the winter.

Technique: At Ana Reservoir, fish for hybrid bass early in the year in the deeper water along the west side of the lake. Hybrid bass do not reproduce, so their continued presence depends on periodic stocking. Because of their size and diet of fish, hybrid bass can be effective at controlling populations of forage fish, such as the tui chub in Ana Reservoir. However, by the time they are one-year old most have moved offshore to open water and switched almost totally to a fish diet. Juvenile hybrid bass spend their first year near shore where they feed on zooplankton and insect larvae.

The only established population is in Ana Reservoir. They have since been introduced into Thompson Reservoir, also in Lake County. Habitat: Hybrid bass were originally stocked in Tenmile Lakes on the south coast and in Ana Reservoir in Lake County. They are typically less than 10 lbs but can grow to 22 lbs. They have two dorsal fins, the front one with eight or nine spines and the rear one with one spine and 13 or 14 soft rays. Features: These fish are light silvery-white, dark on top, and have up to 8 dark, broken stripes running along the sides of their bodies.
