Estuaries perform a crucial role in the life-cycle of many fish (Cronin & Mansueti, 1971; Day, Blaber & Wallace, 1981; Dando, 1984). They provide a migratory route for anadromous and catadromous species and an environment in which the limited number of true estuarine teleosts spend the whole of their life cycle. The upper reaches are colonized by certain freshwater species while the lower regions are penetrated by some marine fish during high tide. However, many marine teleosts enter and remain…

Spatio-temporal fluctuations in the distribution and abundance of demersal fish and epibenthic crustaceans in Yaquina Bay, Oregon

Changes in diversity indices reflected variations in community structure, the influence of migratory species and juvenile fishes, and seasonal changes in dominance, and year-to-year fluctuations in abundance.

Diel variation and seasonal consistency in the fish assemblage of the non-estuarine Sulaibikhat Bay, Kuwait

Although the total number of fishes captured in 1986–1987 and 1987–1988 differed by an order of magnitude, the seasonal changes in numbers, biomass and number of species in the intertidal and subtidal zones were consistent and several species of fishes were shown to have different patterns of behaviour.

Size composition and seasonal changes in abundance of juvenile sole, Solea solea, in the Severn Estuary and Inner Bristol Channel

One of the marine species found in the Severn Estuary for which no seasonal data on density or body size have been presented is the sole, Solea solea (L.), whose relative abundance ranked it amongst the top ten species in two of the five years of this study.

The forth estuary: a nursery and overwintering area for North Sea fishes

The underlying decline of the juvenile cod populations since 1981 in the Forth Estuary is discussed in relation to the recent reduction in commercial fishing quotas.

Influence of site, season and year on contributions made by marine, estuarine, diadromous and freshwater species to the fish fauna of a temperate Australian estuary

Annual variations in the density of Torquigener pleurogramma were related to marked annual differences in the recruitment of the 0+age class and site within the estuary generally influenced the catches of individual species to a greater extent than either season or year, or the interactions between these factors.

Factors influencing community structure and distribution of different life-cycle categories of fishes in shallow waters of a large Australian estuary

The number of species and density of fishes within the whole system were greatest during the summer and autumn, when salinities and temperatures were at a maximum, and declined with distance from the estuary mouth.

Seasonal and spatial differences in the fish assemblage of the non-estuarine Sulaibikhat Bay, Kuwait

The recruitment of large numbers of young of the year Liza carinata (Valenciennes) during March was related to low temperatures in November, the probable time of spawning of this species, andSalinity at the time of sampling was inversely correlated with numbers, which indicates thatLarge numbers of 0+fish recruit to the Bay during the period of maximum fresh water outflow through the Shatt-al-Arab.

Seasonal and spatial changes in the larval fish fauna within a large temperate Australian estuary

A total of 66814 fish larvae, representing 37 families and 74 species, were collected in samples taken monthly between January 1986 and April 1987 from 13 sites located at frequent intervals

Community structure and temporal variability of ichthyoplankton in North Brazilian mangrove creeks

The species composition and dynamics of fish larvae in three mangrove creeks located in the Caete Estuary (north Brazil) were studied monthly using a trap net during diurnal ebb tides, indicating continuous transport out of the mangroves by tidal currents.

Abundance, distribution and age structure offish populations in a Western Australian estuary

The fish fauna of the Peel-Harvey estuarine system is compared with those of Cockburn Sound and the estuaries of the Swan-Avon and Blackwood rivers in Western Australia and with Botany Bay in eastern Australia to help clarify the way in which the estuary was utilised by fish.

Age structure, growth rates, movement patterns and feeding in an estuarine population of the cardinalfish Apogon rueppellii

Measurements of fecundity and the number of oral-brooded eggs demonstrated that the majority of the eggs released by the female are collected and incubated by the males, and the presence of greater amounts of copepods in the diet during the day and of amphipods at night probably reflects the diel activity patterns of the prey.

Seasonal Changes in Density, Composition and Reproductive Biology of Crustacean Populations in the Severn Estuary

Changes in the abundance and composition of crustacean populations in the plankton of the Severn Estuary (England) were followed for 25 consecutive months (1973-1975) to study the growth rate, size at maturity and period of reproductive activity of this species.

Post-pelvic scute (K2) and vertebral counts (VS) indicate that the Severn Estuary herrings are the product of a spring spawning stock, a view entirely consistent with length and field data.

Factors affecting the distribution of juvenile estuarine and inshore fish

It is apparent however, that juveniles of many species are probably not attracted to estuaries per se but to shallow turbid areas, and the influence of high turbidity on fish may be linked to reduced predation pressure and perhaps food supply in shallow water.
