The ecological importance of fish herbivory was examined in a temperate rocky intertidal zone along the central Chilean coast. In this system, the blenny Scartichthys viridis is the most abundant and only herbivorous fish. We describe its diet, determine its field food selectivity (gut contents vs macroalgal field availability comparison) and report on its laboratory dietary preferences in a multiple-choice feeding experiment. Finally, we evaluate the relative effects of fish herbivory and… 

Effects of nutrients, herbivory, and depth on the macroalgal community in the rocky sublittoral.

It is concluded that grazers are able to reduce macroalgae over a large range of nutrient availabilities, up to 12-fold nutrient enrichment in the current experiment, and that the sublittoral depth gradient generates variation in the algal community control exerted by both herbivory and nutrient availability.

Relative contribution of five species of herbivorous fish to the consumption of epilithic algal matrix in the southern Great Barrier Reef

To address concerns of past studies investigating the importance of herbivorous blermies in coral reef systems, the numerical abundance, biomass and distribution of Salariini blenny assemblages at Heron Island, Lady Elliot and North West reefs were compared.


It is argued that spatial refuges on Australasian rocky reefs and differences in the biology of both the seaweed and animal species in Australasia vs. previously studied locations enable palatable seaweeds to persist in the face of herbivory by larger grazers, which reduces the selective pressure on mesograzers to inhabit unpalatable species.

Galápagos macroalgae: A review of the state of ecological knowledge.

A first compilation and discussion of the available literature on macroalgal productivity and dynamics in the Galápagos Archipelago is presented and presents topics for future research.

Coastal fish assemblages and predation pressure in northern-central Chilean Lessonia trabeculata kelp forests and barren grounds

It is suggested that intense fishing activity on large predators, and their resulting low abundances, could result in low predation pressure on sea urchins, thereby contributing to the increase of T. niger abundances in subtidal rocky habitats.

Food resource use in a tropical eastern Pacific tidepool fish assemblage

It is hypothesised that guild formation may be a consequence of aggregation of species at abundant resources in the intertidal zone rather than a direct consequence of inter-specific competition.

Threats to large brown algal forests in temperate seas: the overlooked role of native herbivorous fish

Analysis of temporal and spatial patterns of salema landings in the Mediterranean Sea suggests that salema abundance may have increased recently, suggesting that fish herbivory may also represent a potential threat to algal forests in temperate areas.

Algal populations controlled by fish herbivory across a wave exposure gradient on southern temperate shores.

The study highlights that, even though herbivorous fish diversity may be low, the impacts of particular species may still be high, even in cool temperate waters where fish herbivory is usually considered to be minimal.

The trophic structure of fish in seaweed farms, and adjacent seagrass and coral habitats in Zanzibar, Tanzania

floating seaweed farms attract invertebrates and smaller fish, thus providing feeding grounds for predatory fish, and should be considered as ecologically important habitats as are coral reefs and seagrass beds.



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.

Plant Species Diversity in a Marine Intertidal Community: Importance of Herbivore Food Preference and Algal Competitive Abilities

Predators or herbivores do not simply increase or decrease species diversity of their food, but can potentially do both and the results may apply to most generalized consumers and provide a framework within which previously confusing results can be understood.

Feeding behavior and morphological adaptations in two sympatric sea urchin species in central Chile

Results from field studies indicate that T niger principally consumes benthic algae and in doing so clears significantly more primary space than does L. albus, and that the pyramids of Aristotle's lantern are roughly twice as long as those in L, albus.

Regulation of algal community development in a Macrocystis pyrifera forest

Caging experiments suggest that predatory fishes and sea-stars indirectly affect the algal community by removing sessile animals (primarily bryozoans) which compete with the algae for space.

Feeding capabilities and limitation of herbivorous molluscs: A functional group approach

Algae are subdivided into seven functional groups based on the size and toughness of the plant relative to the feeding ability of the mollusc, and this functional group approach suggests various hypotheses concerning algal community structure, plant/herbivore and herbivore/herBivore interactions, the relative importance of structural defenses in algae, and the evolution of specialized grazers.

The diets of littoral fish from the Cape Peninsula

Despite the overlap in food types consumed, there was considerable subdivi· sion of the resource, much of which may be explained in terms of horizontal and vertical distribution patterns of the various fish species, their habitat preferences, mouth sizes and changes in diet during growth.
