  • Guide to the Coastal Marine Fishes of California
    STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft.

Department of The University of British Columbia Vancouver 8, Canada Date /- 7c ii ABSTRACT Hemigrapsus oregonensis and Hemigrapsus nudus, two beach crabs common on the Pacific Coast of North America, show con• siderable variation in numbers, and species dominance from place to place. To determine why this should be so, a number of experiments were performed., and observations made to de• termine what are the morphological, and physiological differ• ences between the two species, and how the crabs would be affected by the different physical conditions prevailing in different places. In general, it appeared that H. nudus could not tolerate muddiness of the substrate, while H. oregonensis tended to be eliminated from clean areas by predators.
