SynopsisNew information regarding the ecology ofScytalina cerdale was obtained over a four year period as a consequence of a long-term marine ecological study at the Diablo Canyon Power Plant (DCPP), San Luis Obispo County, California. Twenty intertidal fish surveys were conducted at approximately quarterly intervals, between March 1979 and June 1983, at three separate rocky shore locations (stations). During each survey, a total of 108 square meters (36 m2 per station) was searched for fish…

Osteology of the Graveldiver Scytalina cerdale (Perciformes: Zoarcoidei: Scytalinidae)

On the basis of preliminary comparisons, S. cerdale may have phylogenetic affinity with at least some members of the family Stichaeidae (e.g., Xiphister).

Transitional ecological requirements for early juveniles of two sympatric stichaeid fishes,Cebidichthys violaceus andXiphister mucosus

Results from laboratory experiments indicated that young stichaeids select very specific substrata based on fish age (size) and substratum suitability (i.e. adequate refuge) and changes in those preferences over time appear to be the result of morphological similarities for both species at a given age.



Rocky intertidal fish communities of California: temporal and spatial variation

SynopsisWe examined data from our own and published collections of intertidal and shallow littoral fishes of the North American Pacific Coast with respect to temporal and spatial trends in species


Comparison of juvenile diets and foraging patterns with those of adults showed that both foraged in similar manners and in the same general habitats, and the absence of aggressive interactions within or among species and high intra­ specific variability of foraged patterns suggests that little interference or exploitative competition was present.

Pre-operational baseline studies of selected nearshore marine biota at the Diablo Canyon power plant site: 1979-1982

Observations of the presence or absence of fishes at subtidal 30m stations indicate a continued decline in the abundances of lingcod, Ophiodon elongatus and a drop in the abundance of blue rockfish since the 1973 through 1978 study period.

Dynamics and Organization of a Rocky Intertidal Fish Assemblage: The Persistence and Resilience of Taxocene Structure

The test of taxocene persistence and resilience showed that this assemblage was both persistent and resilient over the course of the study, despite repeated defaunation, demonstrating that the relationship of environment to community organization is complex and dependent upon the evolutionary and ecological characteristics of the taxa examined.

The Comparative Ecology of Three Sympatric Species of California Blennies of the Genus Hypsoblennius gill (Teleostomi, Blenniidae)

The ecological differences between the three species seem to indicate that H. gentilis is the most generalized (primitive) form, which survives here in marginal habitats, particularly areas recently modified by man.

New Records of Thirteen Cottoid and Blennioid Fishes for Southeastern Alaska

Three categories of new records for species of fish are reported: (1) extensions of range eastward or southeastward from the Bering Sea or Gulf of Alaska-Hexagrammos octogrammus (Pallas), Artediellus

Experimental assessment of factors influencing microhabitat selection by the two tidepool fishes Oligocottus maculosus and O. snyderi

Interspecific competition and related agonistic behavior were absent from both species and are probably not important to their microhabitat selection and intertidal distribution patterns.

Dietary selectivity in the field and food preferences in the laboratory for two herbivorous fishes (Cebidichthys violaceus and Xiphister mucosus) from a temperate intertidal zone

Food preference tests with up to 19 macrophyte species in the laboratory revealed that both fishes chose to eat three annual rhodophytes in preference to Ulva lobata, an annual chlorophyte that was more abundant in the diets of field-caught specimens.
