Distribution of ehlorinsted hydrocarbons in overlying water, sediment, polychaste, and hornyhead
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).
The local extirpations of 13 backwater species (e.g., blacknose shiner and black bullhead Ameiurus melas) and eight fluvial specialists (e.g., hornyhead
chub Nocomis biguttatus and blackside darter Percina maculata) in downstream river sections potentially indicate a historical reduction in habitat diversity (Roberts and Hitt, 2010).

obtusus)], which could be differentiated from other cyprinids, were divided into the "small cyprinid group" and the "large cyprinid group" [species attaining total lengths >10 cm; in our study represented by common shiner (Luxilus cornutus), creek chub ( Semotilus atromaculatus) and hornyhead
