This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on certain aspects of the life history of the redtail surfperch were collected along the central coast of Oregon, from April 1967 through April 1969. Annulus formation occured during February through June, usually earlier in young than in older fish. Mating occurred from late December to early January, and the young were born from July through September. The number of embryos per female ranged from 1 to 39 (mean 13.3) and increased linearly with the length and weight of the females. Food of the fish from the surf zone included crustaceans (by far the most important group in both frequency of occurrence and total volume) and (in order of decreasing importance) fishes, mollusks, and polychaetes. Parasites of the redtail surfperch were immature nematodes (Anisakinae) ; the digenetic trematode Genitocotyle acirra; the monogenetic trematode, Diclidophora sp.; and the copepods, Caligus sp., Clavella sp., and Argulus catostomi.

Succow and published by . This book was released on 2017 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A network of marine protected areas (MPAs) was established to protect northern California coastal habitats in December 2012. Populations of two indicator species, Amphistichus rhodoterus (redtail surfperch) and Emerita analoga (pacific mole crabs) were characterized within MPAs and reference sites to provide baseline ecological information for this region. Data were gathered using a series of simple field surveys (hook and line fishing surveys for A. rhodoterus along with core and transect surveys for E. analoga). Relative abundance, lengths, and sex ratios of A. rhodoterus did not differ between MPAs and their respective reference sites, whereas condition (overall health) increased in a north to south trend. Although based on a limited number of tag returns, movement of A. rhodoterus within northern California appears to be relatively local. Relative swash zone abundance of E. analoga did not differ between the MPA studied and its respective reference sites. Abundance and biomass of small-sized (10 mm) E. analoga greatly increased during the summer months, likely due to recruitment to northern California beaches. A similar trend occurred for medium and large-sized crabs during spring months, likely due to the timing of reproduction in this region. Both species serve as good indicator species for the northern California region. However, future monitoring for E. analoga should be based on timing of reproduction and recruitment.
