Tidal effects on marsh habitat use by three fishes in the San Francisco Estuary [PDF]

, 2020
Little is known about the ecological importance of low-order tidal marsh channels to fishes in the San Francisco Estuary, California. We conducted a passive mark-recapture study to compare residency, site fidelity, and movement patterns of fishes in a ...

Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

Journal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

Characteristics of fish communites in coastal waters of north-western Australia, including the biology of the threadfin species Eleutheronema tetradactylum and Polydactylus macrochir

, 2006
This study was aimed at determining the characteristics of the fish assemblages in nearshore coastal waters of the remote Canning region of tropical Western Australia and to obtain sound quantitative data on crucial aspects of the biology of the two ...

Evaluation of the community structure of a rockpool fish assemblage from Peniche (Portugal) using clove oil as an anesthetic

Frontiers in Marine Science, 2014
The goal of this study was to provide the first scientific data of the intertidal ichthyofauna community of Peniche. In order to have an accurate assessment, anesthetics were used, since this method is more effective than visual census.

Historical case study of a transfer experiment that demonstrated the importance of the estuarine ecosystem for the survival of Chinook salmon (Oncorhynchus tshawytscha) at the Campbell River estuary, British Columbia, Canada

Journal of Fish Biology, EarlyView.
Abstract Estuary dependence to the survival of Chinook salmon was investigated at the Campbell River estuary, British Columbia, Canada. Replicate batches of marked smolts were transferred from a hatchery and released in 1983, 1984 and 1985 at four ecosystems, two that ensured estuarine experience (river, estuary) and two seawards of the estuary ...

Spatio-temporal variability in ontogenetic guild structure of an intertidal fish assemblage in central Chile Variabilidad espacio-temporal en la estructura de gremios ontogenéticos de un ensamble de peces intermareales de Chile central

Revista Chilena de Historia Natural, 2011
Species resource use can vary throughout ontogeny, potentially affecting community dynamics. This can be particularly important for species facing high variability in environmental conditions and going through several orders of magnitude in size, as ...

Short‐term performance responses of an intertidal fish to sedimentation and warming

Journal of Fish Biology, EarlyView.
Abstract Climate change is altering coastal ecosystems by causing environmental fluctuations, such as increases in temperature and turbidity, which pose major implications for fish physiology and behaviour. Increases in temperature affect fish food intake, swimming capacity and oxygen delivery, while increases in turbidity can impair or enhance prey ...

Vertical distribution of benthic marine organisms on rocky coasts of the Fernando de Noronha archipelago (Brazil)

Brazilian Journal of Oceanography, 1986
Qualitative samples of flora and fauna were collected in several points, from the supralittoral fringe down to 30 m, using mainly aqualungs. Species distribution and abundance were determined along four transects, up to 200 m long, in selected places ...
