“…Ontogenetic change in diet from carnivory or omnivory to herbivory is common in fishes (Mitchell 1953, Ciardelli 1967, Christensen 1978 and is a widespread pattern among other animals with herbivorous adults (Clark & Gibbons 1969, Pough 1973 . Previous studies of the relation between diet and gut morphology in fishes have dealt primarily with comparisons of the adults of various carnivorous, omnivorous, and herbivorous species .…”

“…Contrary to Wells (1980), however, C. lirnatula that were continuously submerged in tidepools actively foraged during daylight hours; in contrast, the small number of C. digitalis found in the pools appeared inactive. Several southern California tidepool fishes are known to feed on acmaeiid limpets (Mitchell 1953, Johnston 1954, Stephens et al 1970. In particular, the kelpfish Gibbonsia elegans was found to be the most abundant of 22 species of tidepool fishes in a survey by Mitchell (1953).…”

Collisella limatula, a limpet found abundantly in the rocky intertidal from Oregon to Baja California, has recently been found to contain a novel triterpene, llmatulone The present paper describes laboratory experiments and field observations that strongly suggest that limatulone acts as a potent chemical defense against some intertidal predators. Intertidal fish and crabs rejected pieces of the foot of C. limatula, but readily ate the foot tissue of CO-occurring gastropods. In contrast, individuals of C. limatula were eaten by seastars, an octopus and sea gulls. Fish antl-feedant activity was restricted to a slngle compound, limatulone, which was present In the foot of the limpet at a mean concentration of 3 5 ppt dry weight. Food pellets containing limatulone at concentrations of 2 0.5 ppt dry weight induced regurgitation in the intertidal fish Gibbonsia elegans, a known llmpet predator. Concentrations of limatulone in C. limatula varied from one geographic location to the next and from one mo to the next. Reasons for these variations are not understood Surveys of the 5 most common limpets in an undisturbed rocky intertidal site revealed that C, llmatula was the most abundant llmpet inside tidepools and on intertidal boulders. Limatulone may act to defend foraging limpets from predatory fishes In tidepools In the boulder field habitat, shell damage lncurred by limpets from wave-borne rocks and debris may expose foot tissue prior to shell regeneration, during which time the chemical defense may release C. limatula from predatory constraints imposed on other Intertidal limpets.

“…Kyphosids are omnivorous, with varying degrees of herbivory (Quast 1968, Feder et al 1974, Bray & Ebeling 1975, Hobson & Chess 1976, Laur & Ebeling 1983. However, even though algae were the dominant component of some species' diets, Quast (1968) and others (Mitchell 1953, Burge & Schultz 1973, Wheeler 1980 assumed that algae were consumed incidentally and were unimportant, relative to animal prey due to the apparent lack of cellulolytic enzymes or gut symbionts for cellulose digestion (Stickney & Shumway 1974). More recent studies have shown that two members of the Kyphosidae in the southern hemisphere (Kyphosus cornelii and K. sydneyunus) are capable of fermentive digestion of marine algae (Rimmer & Wiebe 1987).…”

Diet, food preference, and algal availability for fishes and crabs on intertidal reef communities in southern California

SynopsisHerbivory by wide-ranging fishes is common over tropical reefs, but rare in temperate latitudes where the effects of herbivorous fishes are thought to be minimal. Along the west coast of North America, herbivory by fishes on nearshore reefs is largely restricted to a few members of the Kyphosidae, distributed south of Pt. Conception. This paper presents information on natural diets and results from feeding choice experiments for two abundant kyphosids from intertidal habitats in San Diego, California -Girella nigricans and Hermosilla azurea, and similar data for the lined shore crab, Pachygrapsus crassipes, which also forages over intertidal reefs. These results are compared with the availability of algae in intertidal habitats measured during summer and winter, on both disturbed and undisturbed habitats. The diets of juveniles of G. nigricans and H. azurea collected from nearshore habitats were dominated by animal prey (mainly amphipods), but adults of these fishes, and P. crassipes, consumed algae nearly exclusively, with 26,10, and 14 taxa of algae identified from G. nigricans, H. azurea, and P. crassipes, respectively. Algae with sheet-like morphologies (e.g. Ulva sp., Enteromorpha sp., members of the Delesseriaceae) were the principal algae in the diets of the fishes, and calcareous algae (e.g. Corallina sp., Lithothrix aspergillum) and sheet-like algae (Enteromorpha sp.) comprised the greatest identifiable portion of the shore crab's diet. Feeding choice experiments indicated that the fishes preferred filamentous algae (e.g. Centroceras clavulatum, Polysiphonia sp., Chondria californica) and sheet-like algae (e.g. Enteromorpha sp., Ulva sp., Cryptopleura crispa) over other algal morphologies, whereas the shore crab chose jointed calcareous algae (e.g. Lithothrix aspergillum, Corallina vancouveriensis, Jania sp.) most frequently. The diets and preferences for algae by the fishes were generally most similar to the assemblage of algae available in early successional (disturbed) habitats during summer when sheet-like and filamentous algae are abundant. The shore crab exhibited the opposite trend with a diet more similar to late successional (undisturbed) habitats.
