Estado de conservação de peixes marinhos e estuarinos do Ceará: Gobídeos (Gobiiformes: Gobiidae)

Abstract

In recent decades we can observe how biodiversity has been suffering from anthropic actions, being a great threat to nature conservation. Threat that has been putting several species of various habitats at risk of extinction. Therefore, with the creation of Red Lists of Endangered Species, we have in our hands one of the most important tools for conservation, being a starting point for planning the measures to be taken to reduce the risk of species extinction. The Gobiidae family is one of the most abundant and richest fish families, with about 2,000 species in the world. They have a wide distribution and live in estuarine and marine environments in coastal areas in tide pools and coral reefs. They are small-sized fish that rarely exceed 50 cm. In Brazil there are 40 registered species and in Ceará there are 12 genera distributed in 15 species. The present work aimed to characterize the risk of extinction of gobies in the state of Ceará at a global and regional (Brazil) level. The 15 species of gobies (Gobiidae) that occur in Ceará are classified according to their global conservation status (IUCN) as Least Concern (LC) (n = 9), Data Deficient (DD) (n=1) and Not Evaluated (NE) (n=5) while the national classification (ICMBio) as Least Concern (n = 14) and Vulnerable (VU) (n=1). Of these, 33% are represented in the fish collection ‘Coleção Ictiológica Dias da Rocha – CIDRO’ from the ‘Universidade Federal do Ceará’, which are Bathygobius soporator, Coryphopterus glaucofraenum, Ctenogobius boleosooma, Ctenogobius smaragdus and Gobionelus oceanicus.
