“…This pattern, shared by L. griseus during the wet seasons, is consistent with the commonly observed pattern of declining species richness and total catch with increasing distance inland from creek mouths and oceanic inlets worldwide (e.g. Quinn 1980, Kimani et al 1996, Hajisamae & Chou 2003. Patterns of habitat use may be due to differences in accessibility (sites located within home ranges are used more than those within more rare long-distance movement) or suitability.…”

We examined seasonal utilization of > 500 km of mangrove shoreline within a subtropical continental system by Lutjanus griseus, L. apodus, Haemulon sciurus, H. parra, and Sphyraena barracuda over 2 consecutive years. Mangrove use by these species was examined in terms of frequency of occurrence, density (fish 60 m -2 ), concentration (density among samples where number of fish ≥1), and selection (H 0 : habitat use = availability). All species exhibited either seasonal or spatial habitat selection. Mangrove shorelines closest to the reef tract (Keys) were used by snappers and grunts at much greater levels than their availability would suggest, whereas more inland and expansive mangrove shorelines were largely selected against. This selection pattern was evident year round for L. apodus, H. sciurus, and H. parra. In contrast, L. griseus preferred more inland mangroves during the dry season and Keys mangroves during the wet seasons. S. barracuda exhibited selection for Keys during the wet seasons and was the only species to exhibit non-selection (random) patterns among strata during the dry seasons. These results demonstrate that mangrove shorelines across broad spatial scales are not equivalent in their value as fish habitats, and that estimates of 'essential fish habitat' or 'nursery habitat' using total habitat area will grossly overestimate the amount of functional habitat used by these reef fishes.

Martino & Able (2003) suggested that patterns in estuarine fish assemblage structure across large spatial scales (i.e. >10 km) are due to individual species responses to dominant environmental gradients. Following this logic, demonstrated that the distance between a sample location and an oceanic inlet (a proxy for crossshelf location) was primarily responsible for the separation of life-history stages of snappers and grunts within the mangrove shorelines of Biscayne Bay (southeastern Florida).The above studies are limited in that most considered shoreline mangroves as homogenous units and all ignored size or area of mangrove patches between locations. Thus they offer limited information about the relative importance or value of one mangrove stand compared to another. Although mangroves are gaining increased recognition as habitats that can enhance growth and survival of immature reef fishes, few studies have been conducted at sufficient spatial and temporal scales to examine variation in reef fish utilization within this habitat type (e.g. Faunce & Serafy 2006). These shortcomings are significant considering that the presence of mangrove-lined embayments enhances adult stocks of reef fishes in the western Atlantic (Dorenbosch et al. 2004, Mu...

“…One factor that could contribute to the low abundances in Cattle Creek is the occurrence of regular, annual floods. Flooding can influence abundances of estuarine fish populations both directly (Marais 1982(Marais , 1983, and indirectly by its influence on salinity (Hoff & Ibara 1977, Marais 1988, Moser & Gerry 1989, which is important in structuring fish communities in tropical estuaries (Quinn 1980). During the present study annual flooding of Cattle Creek caused a marked depression of salinity compared to the other 2 creeks.…”

Epinephelus coioides and E. malabaricus are closely related species of serranid fishes. They are similar in appearance, occupy the same habitats and are represented in estuaries of northeastern tropical Australia almost entirely by juveniles. Fish traps were used to sample these 2 species from 3 estuaries on the northeast coast of tropical Australia over a 2 yr period Patterns of distribution. abundance and size structure were compared. Despite the sirmlarities between the 2 species, they showed quite different patterns of distribution and abundance, both within and between estuaries. In seaward parts of the estuaries the numbers of E. coioides were similar to or greater than those of E. malabaricus. However, in upstream areas E. malabaricus became much more abundant than E. coioides. The reasons for this change in dominance are unknown. However, upstream areas of the estuaries exhibited extreme levels of salinity (either hypersaline or hyposahne) and catches of the 2 species correlated with the maximum deviation in salinity. This suggests that i f salinity, or some correlated variable, does influence the abundance of the 2 species, it is through long-term effects rather than shortterm changes. Regardless of the reason, these spatial differences in abundance suggest that E. malabaricus is better equipped to deal with the challenges of estuary life than is E. coioides.

“…However, a small number of species dominates the structure of the local community in terms of numerical abundance (Quinn 1980, Lugendo et al 2007). In Madagascar, for example, five species were found representing this total (Laroche et al 1997); in Australia, only three species (Kwak and Klumpp 2004) were found and in an estuary in the Northeast Brazil (Barletta et al 2005), six species.…”

Seagrass beds are used by juvenile fishes in different ways, generally as nursery sites, shelter from predators, reducing competition and increasing availability of food resources, thus establishing a relationship of connectivity with other ecosystems. In the present study, the community structure of the ichthyofauna associated with seagrass beds on the Formoso River (Pernambuco -Brazil) was evaluated during the winter of 2008. Twenty-seven manual trawls (15 daytime and 12 nighttime) were performed, and a total of 358 fishes belonging to 18 families, 21 genus and 25 species were collected. The Catch Per Unit Effort (CPUE) by trawling average was 13.5 and 4.95 individuals per species per trawl. The most abundant families were Scaridae (n = 111), Tetraodontidae (n = 63), Lutjanidae (n = 56), Mullidae (n = 39) and Engraulidae (n = 19). Ecological indices for dial changes were always higher for the night period, confirming that such areas are used more frequently during this period. The need for measures to conserve these areas is emphasized, by its importance and vulnerability to human impacts.
