Atlas of marine bony fish otoliths (Sagittae) of Southeastern - Southern Brazil Part I: Gadiformes (Macrouridae, Moridae, Bregmacerotidae, Phycidae and Merlucciidae); Part II: Perciformes (Carangidae, Sciaenidae, Scombridae and Serranidae)

Abstract

A B S T R A C TThe drawings, detailed pictures, precise descriptions and measurements that characterize otoliths must be made available for studies in various areas, including taxonomy, phylogeny, ecology, fisheries, paleontology, diversity, predator-prey relationships and modeling. The Collection of Teleostei Fish Otoliths of Southeastern-Southern Brazil (COSS-Brasil) of IOUSP contains 45,000 pairs of otoliths from 210 species. This publication is the first in a series that will constitute an atlas of Teleostei otoliths for southeastern-southern Brazil and presents the results of the morphologic and morphometric analyses of 11 Gadiformes and 36 Perciformes species by means of the most commonly used features, measurements and indices. Three otoliths of each species were illustrated and photographed whenever possible. The frequency of occurrence was calculated for each characteristic by total length classes (TL), and the ontogenetic differences were analyzed (multiple χ2 test; significance 0.05). Morphometric analyses were conducted for each characteristic per total length (TL) class and for the whole sample, and the ontogenetic differences were analyzed. R E S U M OA disponibilidade de desenhos, fotos detalhadas, descrições precisas e medidas que caracterizem os otólitos são ferramentas imprescindíveis para diversas áreas: taxonomia, filogenia, ecologia, pesca, paleontologia, diversidade, relações presa/predador e modelagem. Da Coleção de Otólitos de Peixes Teleósteos da Região Sudeste-Sul do Brasil (COSS-Brasil), IOUSP, constam quarenta e cinco mil pares relativos a 210 espécies. Esta publicação é a primeira de uma série que constituirá um atlas de otólitos para Teleostei da região sudeste-sul brasileira e apresenta os resultados de análises morfológicas e morfométricas de 11 espécies de Gadiformes e 36 de Perciformes das medidas e índices usualmente realizados. Foram desenhados e fotografados três otólitos de cada espécie sempre que possível. A frequência de ocorrência foi calculada por classes de comprimento total (TL) e para toda a amostra, e diferenças ontogenéticas foram analisadas.

Morphology and morphometric relationships for sagitta otoliths in Lutjanus argentiventris (Pisces: Lutjanidae) and Hyporthodus acanthistius (Pisces: Serranidae) from the Colombian Pacific Ocean

“…As for the observed red grouper sagitta otoliths, these revealed features similar to those described in other serranid species, for instance, Dules auriga and Serranus atrobranchus from Brazil and Nemipterus japonicus (Nemipteridae; Seyfabadi et al, 2014); These parallels ought be regarded with caution, since serranid fishes are known to exhibit large interspecific variation in otolith morphology (Rossi-Wongtschowski et al, 2014). No otolith morphology descriptions or morphometric relationships were found for the species (Hyporthodus acanthistius) or the genus.…”

Feeding ecology of the common bottlenose dolphin, Tursiops truncatus, in southern Brazil: analyzing its prey and the potential overlap with fisheries

“…Fish otoliths and cephalopod beaks were identified as far as possible to the species level, using local reference collections (e.g. CEPSUL/ICMBio, for cephalopod beaks) and identification guides (e.g., MENEZES; FIGUEIREDO, 1980;WAESSLE et al, 2003;ROSSI-WONGTSCHOWSKI et al, 2014).…”

Does the closed fishing season influence the ichthyofauna consumed by Larus dominicanus?

“…Only the otoliths with preserved structures were identified and measured. The identification was carried out by using otolith structures according to the literature (CORRÊA; VIANA, 1992;ABILHÔA;LEMOS et al, 1992;LEMOS et al, 1995;DI BENEDITTO et al, 2001;CARVALHO et al, 2014;ROSSI-WONGTSCHOWSKI et al, 2014). The length and weight of ingested fish were estimated by measuring the otolith length (the longest distance between the anterior and posterior margins) and ventral height of the otolith (longer straight distance, between a central point of intersection of the tail with the ostium and the ventral margin).…”
