A ictiofauna do Canal de Bertioga, São Paulo, Brasil

Abstract

Abstract:The Bertioga Channel, on the coast of the São Paulo state, is delimited by the continental shore and the island of Santo Amaro, and represents a secondary connection of the Santos-São Vicente estuarine complex to the ocean and adjoins the municipalities of Santos, Guarujá and Bertioga. In the present study collections were made between December 2009 and November 2010 in the northern stretch of the Bertioga Channel (23° 51 ' 23,83" S, 46° 07' 58, 87" W to 23° 53' 31,72" S, 46° 11' 17,74" W) in order to provide an inventory of the ichthyofauna of the region. A total of 1,429 specimens were collected, belonging to 78 species, 67 genera, 39 families and 14 orders. The most species rich families were Sciaenidae (nine spp.), Carangidae (nine spp.), Haemulidae (seven spp.), and Ariidae (five spp.). The most abundant species were Stellifer rastrifer (n = 243), Harengula clupeola (n = 182), Cathorops spixii (n = 144), Oligoplites palometa (n = 109) and Mugil curema (n=102). The species Achirus lineatus, Atherinella brasiliensis, Cathorops spixii, Chaetodipterus faber, Citharichthys spilopterus, Genidens genidens, Micropogonias furnieri and Stellifer rastrifer, were collected in all seasons of the year. Of the species encountered, six were considered constant, 19 accessorial and 53 occasional. In relation to habitat association, 40 species are marine-estuarine, 26 species marine, 11 species estuarine and one species freshwater, being 52 demersal species and 26 pelagic species. Eleven species are included in red lists. Additionally, an identification key to the species of the northern stretch of the Bertioga Channel is presented. 23° 51' 23,83" S e 46° 07' 58,87" O e 23° 53' 31,72" S e 46° 11' 17,74" O), com o objetivo de inventariar a ictiofauna da região. Foram coletados 1.429 exemplares, pertencentes a 78 espécies, incluídas em 14 ordens, 39 famílias e 67 gêneros. As famílias mais especiosas foram Sciaenidae (nove spp.), Carangidae (nove spp.), Haemulidae (sete spp.), e Ariidae (cinco spp.), e as espécies mais abundantes foram Stellifer rastrifer (n = 243), Harengula clupeola (n = 182), Cathorops spixii (n = 144), Oligoplites palometa (n = 109) e Mugil curema (n = 102), sendo que Achirus lineatus, Atherinella brasiliensis, Cathorops spixii, Chaetodipterus faber, Citharichthys spilopterus, Genidens genidens, Micropogonias furnieri e Stellifer rastrifer, ocorreram em todas estações do ano. Das espécies encontradas, seis foram reconhecidas constantes, 19 acessórias e 53 ocasionais. Em relação aos seus hábitos, 40 espécies são marinho-estuarinas, 26 marinhas, 11 estuarinas e uma de água doce, sendo 52 espécies demersais e 26 pelágicas. Onze espécies são relacionadas em listas de espécies ameaçadas. Adicionalmente, é apresentada uma chave de identificação para as espécies do trecho norte do Canal de Bertioga.

Potential of carapeba (Eugerres brasilianus) for aquaculture production

“…It is likely that the E. brasilianus may migrate for reproductive purposes from fresh water to coastal environment, having sheltered and good food supply near the mouth of a river as a transitional environment/area, thus completing their reproductive cycle. Such hypothesis is consistent with the findings of Chaves & Otto (1998) with rhombeus Diapterus species, and also with Barbanti et al (2013) analyzing the fauna fish in the Bertioga Channel in São Paulo.…”

Ichthyofauna as an environmental quality indicator of the Bertioga Channel, São Paulo (Brazil)

“…An ichthyofauna inventory of the Bertioga Channel was recently published, presenting 78 species, 67 genera and 39 families, caught by 10 different fishing techniques (BARBANTI et al, 2013). To the same area, ROCHA and DIAS (2015), using only otter-trawling samples, added fifteen species to the inventory of BARBANTI et al, (2013).…”

“…To the same area, ROCHA and DIAS (2015), using only otter-trawling samples, added fifteen species to the inventory of BARBANTI et al, (2013). On the other hand, PORCARO et al (2014) described the distribution of the sciaenid larvae in the estuarine system and adjacent continental shelf off Santos, highlighting the region as a Sciaenidae spawning area.…”

Inventory of Chondrichthyes and Actinopterygii species collected in the central coast of São Paulo State, Brazil

“…Some ichthyofaunistic surveys have been conducted in the central coast of Sã o Paulo state; among these surveys, we can highlight Vazzoler (1970), Paiva-Filho et al (1987), Giannini & Paiva-Filho (1990), and Grac¸a-Lopes et al (1993) for the Santos Bay and Barbanti et al (2013) for the Bertioga Channel. Although already investigated, little information has been published about the ichthyofauna inventory of the continental shelf ecosystem (Vazzoler et al 1982, Fachinni, 1999.…”
