TL;DR: In this paper, a review of the community structure and function of fishes inhabiting estuaries and other transitional waters in terms of categories or guilds is presented, with a global perspective on this categorization by presenting new or refined definitions for the categories, lists the synonyms from the literature and illustrates the concepts using examples from geographical areas covering north and central America, north and southern Europe, central and southern Africa, Australia and the Indo-Pacific.

TL;DR: This review details factors influencing the ichthyofaunal community structure in South African estuaries and concludes that South Africa requires an expansion of the existing Estuarine Protected Area (EPA) network, as well as the upgrading of selected 'estuarine reserves' where fishing is permitted, into 'estuary sanctuaries' where no exploitation of biological resources is allowed.

TL;DR: This review examines the rationale and value of selecting fishes as bio-indicators of human induced changes within estuaries, using examples from both the northern and southern hemispheres.

TL;DR: This paper defines, details and affirms paradigms that can be grouped into those covering firstly the science (definitions, scales, linkages, productivity, tolerances and variability) and secondly the management (pressures, valuation, health and services) of estuaries.
