Reproduction Comments: Spawns in early summer. Eggs hatch in about a week. Sexually mature when 3-4 years old in California (Moyle 1976)
Habitat Type: Freshwater
Non-Migrant: Y
Locally Migrant: N
Long Distance Migrant: N
Estuarine Habitat(s): River mouth/tidal river
Riverine Habitat(s): BIG RIVER, Low gradient, MEDIUM RIVER
Lacustrine Habitat(s): Deep water, Shallow water
Special Habitat Factors: Benthic
Habitat Comments: This catfish inhabits sluggish lower reaches of coastal streams, sloughs, warmwater lakes, reservoirs, farm ponds, and tidal freshwater estuaries; it requires water above 20 C in summer. Spawning occurs over saucer-shaped nests cleared on the bottom by males and females.
Adult Food Habits: Invertivore, Piscivore
Immature Food Habits: Invertivore, Piscivore
Food Comments: Feeds opportunistically mainly on bottom invertebrates, but also eats carrion and fishes, occasionally plankton-feeding fishes of reservoir surface waters (Moyle 1976).

Population/Occurrence Delineation
Help
Group Name: Bullheads and Small Catfishes

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Data on dispersal and other movements generally are not available. Separation distance (in aquatic kilometers) is arbitrary but reflects the likely low probability that two occupied locations separated by less than several kilometers of aquatic habitat would represent truly independent populations over the long term.

Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.

Notes: This Specs Group includes catfishes that generally are less than 50 cm in length and all bullheads.
