Figure 401, all of which are consrdered resident specres. Commerctal/recreational species that use the estuary ~nclude California halibut (Parallchthys californ~cus), surfperches, anchovies. pleuronectids, croakers, and sea bass, although none of these occur rn high numbers relative to so-called resrdents November 1979, and from mid-February through March 1980, using a 1/4-inch-mesh seine. Sampling was interrupted from late November to mid-February due to flooding, and the sampling effort was abandoned after mid-March because of flood-induced changes. The catch from five sampling dates was dominated by topsmelt and included eight other species. During late January and early February 1980 and again in mid- February through March, major flooding in the estuary lowered salinities to zero. Samples collected after the 1980 flood had fewer species, Nordby (SDSU, unpubl data) sampled three with topsmell and mullet most abundant These sites for adult and juvenile flshes from August to data support the frndings of other rnvestigators in Figure 40. The fish community includes kiilifish (upper tetl and upper rtght, In shallow water). mullet (above water and left center), topsmelt (center, near surface), barred sandbass (right. In water coiumn), diamond turbot (lower left. on substrate), California halibut (center, on substrate), staghorn skulpin (center foreground. on bottom), cheekspot goby, longjaw mudsucker (in lower burrow) and arrow gobies (in upper burrowl. Enlarged below are the longjaw mudsucker and barred sandbass. Mclntire collection, copyright 1986 by Zedler.
