SynopsisFish assemblages at an artificial reef site, a natural reef site and a sandy-mud bottom site, on the shelf (depth 130 m) off Iwate Prefecture, northern Japan, were surveyed by using a bottom trammel net from May 1987 to March 1993. A total of 12 173 fishes of 48 species were recorded. Physiculus maximowiczi was dominant and comprised 69% of the total numerical abundance. Total fish number was lowest in March at all the 3 sites when P. maximowiczi migrated to deeper and warmer waters…

Artificial reefs can mimic natural habitats for fish and macroinvertebrates in temperate coastal waters of the Yellow Sea
Abstract The deployment of artificial reefs to enhance the abundance of reef-associated species in the coastal waters of China occurs on a very large scale. However, the ability of these artificial
Fish Assemblages on Estuarine Artificial Reefs: Natural Rocky-Reef Mimics or Discrete Assemblages?
Estuarine artificial reef assemblages are likely to differ significantly from adjacent rocky-reef, potentially as a result of physical factors such as reef isolation, coupled with species specific behavioural traits such as the ability of some species to traverse large sand flats in order to locate reef structure, and feeding preferences.
Seasonal Dynamics of Fish Assemblages on Breakwaters and Natural Rocky Reefs in a Temperate Estuary: Consistent Assemblage Differences Driven by Sub-Adults
The results indicate that breakwaters in temperate estuaries are capable of supporting abundant and diverse fish assemblages with similar recruitment process to natural reefs, however, breakwaters may not approximate all aspects of natural assemblage structure, with differences maintained by a single-life stage in some cases.
The comparative effects of habitat complexity on faunal assemblages of northern temperate artificial and natural reefs
Overall abundance for many of the species examined was 2 – 3 times higher on the complex artificial habitats than on simple artificial or natural reef habitats, suggesting enhanced habitat availability produced by the increased structural complexity delivered through specifically designed artificial reefs may have the potential to augment faunal abundance while promoting species diversity.
The Influence of Habitat Complexity on Reef Fish Communities in the Northeastern Gulf of Mexico
Evidence is provided that habitat complexity increased reef fish species diversity in the northeastern Gulf of Mexico and that community composition varied between years, which provided evidence to support the hypothesis that habitat simplicity increased reefFish species diversity.
The Development of Communities on Large-scale Breakwater Reefs with a Comparison to Natural Reefs
Coastal defense structures currently make up more than half of the coastline in many regions, yet their ecological role is poorly understood. These structures represent novel habitat open to
Monitoring of reef associated and pelagic fish communities on Australia's first purpose built offshore artificial reef
This study demonstrates artificial reefs can provide habitats for a diverse group of fish, but the assemblages are unlikely to mimic those on natural reefs, and shows that longer term monitoring periods are required to gain a robust understanding of the response of fish to reef deployment.
Quantifying biotic interactions with inshore subtidal structures : comparisons between artificial and natural reefs
Artificial reefs have been deployed purposely worldwide to influence physical and biological processes around coastlines and in inshore waters; often to augment recreational diving and fishing,
Succession of reef fish community at the coral area rehabilitated with coral transplantation and artificial reef in West Sumatra, Indonesia
An established technique to rehabilitate the damaged coral reefs is by combining coral transplantation and artificial reef. This technique is able to increase the percentage of living coral cover
Individual-based modeling of an artificial reef fish community: Effects of habitat quantity and degree of refuge
A multi-species, individual-based model was developed and applied to examine the long-term effects of increasing number of reefs on fish weight, abundance, and biomass and showed that increasing the number of Reefs generally produced higher biomass, but at the cost of slower growth, and smaller individuals.


Results showed that data on artificial reef assemblages based solely on the abundance of resident species are biased, and provided a partial test and support for a model predicting the importance of attraction over production for artificial reefs located in areas with high reef availability.
Diets of the demersal fishes on the shelf off Iwate, northern Japan
Interspecific dietary overlap was low in most cases suggesting that food resources were well partitioned, although some high overlap was observed among the pelagic fish feeders, A. alcicornis, and Gymnocanthus intermedius, and among the benthic invertebrate feeders.
Factors affecting fish diversity on a temperate reef: the fish assemblage of Palos Verdes Point, 1974–1981
It is suggested that the presence or absence of kelp has little effect on the abundance of most fish species in a high relief environment and kelp bed fish assemblages within the Southern California Bight vary in a south-north direction.
Artificial reef modules constructed of plastic or concrete were deployed at three sites in deep water on Penguin Bank. Hawaii. in October 1985. Fish communities were censused shortly after deployment
Biomasses, catch rates and abundances of demersal fishes, particularly predators of prawns, in a tropical bay in the Gulf of Carpentaria, Australia
In Albatross Bay, the complex of factors affecting fish abundances and the magnitude of between-cruise differences indicate that such tropical communities may be unpredictable and are not seasonally constant.
Density, biomass and community structure of demersal fishes off the Pacific coast of northeastern Japan
Density and biomass of demersal fish community were high on the uppermost slope, and the high abundance resulted from low-diversity communities dominated byTheragra chalcogramma, Gadus macrocephalus andPhysiculus maximowiczi.
Depth-gradient structure of the demersal fish community on the continental shelf and upper slope off Sendai Bay, Japan
The demersal f ~ s h community was examined at 15 sites on the continental shelf and upper slope off Sendai Bay, Japan, from 1989 to 1991. The community structure was analyzed along the depth
Demersal assemblages of the continental shelf and slope edge between the Gulf of Tehuantepec (Mexico) and the Gulf of Papagayo (Costa Rica)
Correlation of DCA Axis 1 with depth, temperature, salinity and oxygen showed that depth is the main gradient along which fauna1 changes occur.
Study of the demersal assemblages of the continental shelf and upper slope off Congo and Gabon , based on the trawl surveys of the RV ' Dr Fridtjof Nansen '
The structure of the demersal assemblages (fish, crustaceans and cephalopods) of the continental shelf and upper slope off Congo and Gabon (from about 1 to 5" S) was studied based on the trawl survey
Estimation of the spawning season of the morid fish Physiculus maximowiczi collected from the coastal waters of Iwate Prefecture, Japan
The present results may suggest that P. maximowiczi spawns during the winter in deeper water than the continental shelf, and the ovaries of fish from 330m were more developed than those of Fish from 130m.
