This chapter provides an overview of the main drivers of change in estuarine systems, their
expected causes and impacts on estuarine fish and fisheries. An analysis of global, regional …

The fish assemblage structure was analyzed along an estuarine gradient of a small
macrotidal estuary (the Canche, France). Fishes were collected every two months between …

Estuaries consist of a complex mosaic of many distinctive habitat types. Each one may
perform several vital functions in the functioning of the whole system and although its value …

The transition from freshwater to seawater is integral to the life history of many fishes.
Diverse migratory fishes express anadromous, catadromous, and amphidromous life …

Stable carbon and nitrogen isotopes (δ13C, δ15N) were used to analyse food web
dynamics of two of the main estuaries of the Portuguese coast: Tejo and Mira. The ultimate …

The importance of shallow littoral habitat is a long standing paradigm of estuarine ecology,
particularly in facilitating the nursery role they play for many fish. Diel cycles have been …

Light is the most important synchronizer of melatonin rhythms in fish. This paper studies the
influence of the characteristics of light on plasma melatonin rhythms in sole. The results …

One of the present concerns of fish biologists involves defining and identifying nursery
habitats in the context of conservation and resource management strategies. Fish nursery …

Connectivity plays a key role in biodiversity conservation as it sustains ecological processes,
such as migrations, important for the maintenance of populations. Connectivity is especially …

The use of intertidal sandy beaches by fish and macrocrustaceans was studied at different
temporal scales at the mouth of a tropical estuary. Samples were taken along the lunar and …
