Ichthyofauna marine of the Island of Santa Catarina, Southern Brazil: checklist with comments on the species

Abstract: This study aimed to present a checklist of marine fishes from coastal environments of the Island of Santa Catarina, including comments on the zoogeographic affinities, conservation status of each species, and functional groups. A total of 169 fish species belonging to 30 orders and 58 families were recorded. The most speciose families were Sciaenidae, Carangidae and, Engraulidae, representing 26,62% of the recorded species. Anchoa was the richest genus, followed by Sphoeroides and Cynoscion. Most of the species have their distribution limited to the western Atlantic, and two groups of fish were distinguished according to the species distributions: 1) species occurring in the Caribbean and in the Brazilian Province; and 2) Transatlantic species. Thirteen species are critically threatened, 10 are overexploited on the Brazilian coast, and 2 are threatened by extinction. Most of the species are either marine stragglers or marine migrants, and most of them are zoobenthivores, piscivores, or both.

摘要：本研究旨在编制圣卡塔琳娜岛沿岸海域的海洋鱼类名录，并对各物种的动物地理学亲缘关系、保护现状及功能类群进行评述。本研究共记录了隶属于30目58科的169种鱼类。物种丰富度最高的三个科为石首鱼科（Sciaenidae）、鲹科（Carangidae）以及鳀科（Engraulidae），占记录物种总数的26.62%。银汉鱼属（Anchoa）是物种丰富度最高的属，其次为兔头鲀属（Sphoeroides）和犬牙石首鱼属（Cynoscion）。多数物种的分布局限于西大西洋海域，根据物种分布格局可划分为两类鱼类：1）分布于加勒比海及巴西动物地理区的物种；2）跨大西洋分布物种。有13个物种处于极危状态，10个物种在巴西沿岸遭到过度捕捞，另有2个物种濒临灭绝。多数物种为海洋偶见种或海洋洄游种，且大多为底栖动物食性、食鱼性，或兼具两种食性。
