Refuge Resources<br />

There were also a number of fish collected in the early 1970s that were not collected in the 1920s.<br />

These included: California corbina, spotted seabass (Paralabrax maculatofasciatus), white<br />

croaker (Genyonemus lineatus), pipe surfperch (Damalichthys= Rhacochilus vacca), white<br />

surfperch (Phanerodon furcatus), giant kelpfish (Heterostichus rostratus), <strong>and</strong> notably, topsmelt,<br />

which was abundant in the 1970s study <strong>and</strong> one of the top ten fish taxa collected in the 1990s.<br />

Also notable is that in the 1970s, many species, including bonefish (Albula vulpes) <strong>and</strong> cheekspot<br />

goby (Ilypnus gilberti), were found to be uncommon in the Bay <strong>and</strong> kelp pipefish (Syngnathus<br />

californiensis) <strong>and</strong> barred pipefish (Syngnathus auliscus) were completely absent. However,<br />

collections made in the 1990s as part of the Port of Long Beach’s restoration monitoring program<br />

found cheekspot goby <strong>and</strong> barred pipefish to be relatively common on the Refuge.<br />

One of the requirements of the Port of Long Beach’s restoration project, which restored<br />

approximately 116 acres of subtidal <strong>and</strong> intertidal habitat on the Refuge, was to conduct a five-year<br />

monitoring program to demonstrate that the objectives of the restoration had been met. The<br />

Forrestal, Case Road, 7 th Street, <strong>and</strong> Perimeter Ponds were all created as part of this mitigation<br />

project to offset impacts to fish habitat. To assess the habitat quality of the restored areas relative<br />

to the natural wetl<strong>and</strong>s in Anaheim Bay, data on fish abundance, species richness, <strong>and</strong> composition<br />

in the restored areas were collected between 1990 <strong>and</strong> 1995. The data obtained from the restored<br />

areas were then compared with data collected at an undisturbed reference site in Anaheim Bay.<br />

The results of the monitoring indicated that fish abundance in the mitigation area was not<br />

significantly different from the reference site; however, significantly more species of fish were<br />

collected in the mitigation areas (MEC 1995). There were also substantial differences in species<br />

composition, which indicated that the mitigation areas provided more habitat for fish than did the<br />

reference site. One reason for this may be that the subtidal habitat in the mitigation areas is<br />

substantially deeper across the tidal range than at the reference site. By the end of the five-year<br />

monitoring program, portions of the ponds had been colonized by eelgrass, which provided quality<br />

habitat for pipefish, shiner surfperch, <strong>and</strong> topsmelt (MEC 1995). The mitigation ponds continue to<br />

provide important habitat for fish <strong>and</strong> other marine organisms. Table 4-7 lists the five most<br />

commonly collected fish species in the mitigation areas <strong>and</strong> the reference site during the five-year<br />

monitoring program.<br />
