Abstract
Abstract Comprehensive species checklists are essential to effectively implementing preservation and recovery measures, and should assess conservation status, vulnerability degree and anthropogenic threats. This checklist was compiled from fish species recorded in surveys conducted over the last 30 years in the shallow inner continental shelf in the State of Paraná, Brazil. Information on biogeography, conservation status, economic importance and degree of species’ vulnerability are provided. A total of 272 fish species were recorded, spanning 25 orders and 88 families. The most speciose family was Sciaenidae (25 species), followed by Carangidae (23), Engraulidae (10), Carcharhinidae (9), Epinephelidae (9) and Paralichthyidae (9). Most species occurring in Paraná’s shallow inner continental shelf are restricted to the West Atlantic. In terms of economic importance, 93% (253) of the species recorded were of fishery, aquaculture or aquaria interest. A notable fraction (39%) of the recorded species was classified as having moderate to very high vulnerability to extinction. In particular, 28 species (10%) were listed as globally endangered, and 34 species (12%) were listed as endangered in the Brazilian territory.
Highlights
The State of Paraná, in southern Brazil, has a 98 km long coastline, and is cut by two large estuarine complexes, namely, the Paranaguá Bay to the north and the Guaratuba Bay to the south

A total of 272 fish species (234 Actinopterygii and 38 Elasmobranchii) distributed over 25 orders and 88 families were recorded in the shallow inner continental shelf of Paraná (Table 2)
Summary
The State of Paraná, in southern Brazil, has a 98 km long coastline, and is cut by two large estuarine complexes, namely, the Paranaguá Bay to the north and the Guaratuba Bay to the south. There have been several studies on the fish fauna in the Paranaguá Estuarine Complex (Hackradt et al 2009; Félix-Hackradt et al 2010; Ignácio & Spach 2010; Contente et al 2011; Passos et al 2012; Pichler et al 2015, 2017; Possatto et al 2017) and in the Guaratuba Bay (Chaves & Corrêa 1998; Chaves & Vendel 2001). We have compiled a checklist of fish species inhabiting the shallow inner continental shelf of Paraná. Considerations about geographic distribution, conservation status, economic importance, and degree of vulnerability to extinction are provided. This checklist compiles useful information in a single document that should be of great help in devising measures of preservation and species recovery
