turbot (Pleuronichthys verticalis) in the coastal ocean, southern California, USA.
Eleven species were newly collected during this period including: largescale stoneroller (Campostoma oligolepis), hornyhead
chub (Nocomis biguttatus), golden shiner (Notemigonus crysoleucus), southern redbelly dace (Phoxinus erythrogaster), river carpsucker (Carpiodes carpio), highfin carpsucker (Carpiodes velifer), channel catfish (Ictalurus punctatus), tadpole madtom (Noturus gyrinus), mosquitofish (Gambusia affinis), warmouth (Lepomis gulosus), black crappie (Poxomis nigromaculatus), and freshwater drum (Aplodinotus grunniens) (Table 2).
Given its depth range, this species may be an ecological counterpart of the hornyhead
turbot, Pleuronichthys verticalis, which occurs off California and the outer coast of Baja California and of the ocellated turbot, Pleuronichthys ocellatus, which occurs in the northern Gulf of California (Fitch 1963, Allen 1982).

If the hornyhead
