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 />
