SynopsisThe distribution patterns, diets, and substratum (refuge) requirements of early juveniles of two sympatric stichaeid fishesCebidichthys violaceus andXiphister mucosus, were investigated in a rocky intertidal habitat at Diablo Canyon, California. Monthly investigations were conducted at low tide for four consecutive months, to assess ontogenetic differences in distribution, diet, and refuge requirements within and between the two species. Distinct differences in vertical zonation were… 

Gut length and mass in herbivorous and carnivorous prickleback fishes (Teleostei: Stichaeidae): ontogenetic, dietary, and phylogenetic effects

Ontogeny and phylogeny more than diet appear to influence gut dimensions in the four species, thus favoring genetic adaptation over phenotypic plasticity as the major force acting on digestive system features in the two prickleback clades.

Digestive Enzyme Activities in Herbivorous and Carnivorous Prickleback Fishes (Teleostei: Stichaeidae): Ontogenetic, Dietary, and Phylogenetic Effects

The hypothesis that fishes with relatively broad diets can modulate digestive enzyme activities in response to changes in dietary composition is supported.

Overall, glycogen storage level and alkaline phosphatase activity responded primarily to diet, whereas esterase activity was also influenced by ontogeny and phylogeny and differed between intestinal regions among the species.

Digestive enzyme activities in carnivores and herbivores: comparisons among four closely related prickleback fishes (Teleostei: Stichaeidae) from a California rocky intertidal habitat

Three digestive enzymes in four species of closely related prickleback fishes were analysed to assess whether diet or phylogeny played a larger role in influencing digestive enzyme activity, and activity of α-amylase follows a pattern influenced more by phylogeny than by diet in these fishes.

Osteology of the prickleback genus Xiphister (Cottiformes: Zoarcoidei: Stichaeidae)

The skeletal anatomy of the genus Xiphister is described and illustrated, clarifying aspects of the skull roof and neurocranium, jaws, suspensorium, opercular series, vertebral column, dorsal and anal fins, trunk lateral-line canals and pectoral girdle and the elements of the hyoid and gill arches and scales are described.

Evidence is provided for genetically programmed upregulation of trypsin gene expression with ontogeny in both the carnivorous and herbivorous species but in response to the high‐protein artificial diet only in the carnivores.

Behavioural Overlap in Six Caribbean Labrid Species: Intra- and Interspecific Similarities

There was a remarkable similarity in ontogenetic changes in these behaviours for all of the species studied, and notable differences among species included the greater frequencies of hiding by juvenile H. radiatus, and all life intervals of H. garnoti.

Sequence and expression of an α-amylase gene in four related species of prickleback fishes (Teleostei: Stichaeidae): ontogenetic, dietary, and species-level effects

The results showed no dietary effect in any species but significant ontogenetic and species-level effects in Cebidichthys violaceus, as well as in the sister species Xiphister mucosus and X. atropurpureus, showing the importance of α-amylase in the herbivores and omnivores.

Comparative transcriptomics reveal tissue level specialization towards diet in prickleback fishes

The results suggest that the intestine is plastic in function, but the liver may be where specialization manifests since this tissue shows species-specific gene expression patterns that match with natural diet.

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.

FOOD HABITS OF JUVENILE ROCKFISHES (SEBASTES) IN A CENTRAL CALIFORNIA KELP FOREST

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.

It is indicated that optimal diet models cannot be based solely on energy maximization but should also include nutrient constraints in order to more accurately predict the seasonally fluctuating mixed diets of these fishes and other generalist herbivores.

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

Lack of Planktonic Dispersal of Rocky Intertidal Fish Larvae

Data for the rocky nearshore area reveal that all stages of larvae remain inshore, not just those within a narrow size range, suggesting that populations of rocky intertidal fishes may be relatively isolated genetically.
