Abstract
The spatial distribution of small pelagic fishes off the Southeastern Brazilian coastal area (22°-29°S) was investigated over six periods, from 1995 to 2010, in the context of the Program Prospection and Assessment of the Biomass of the Sardine, Sardinella brasiliensis in order to provide data about their pattern of distribution and biomass. A checklist of the species collected is presented herein with data on geographic position and depth of captures. Such information is intended to be a reference about the fauna that occupied the region in the period under investigation, and allow future comparisons about the resilience of the local fauna, i.e., the detection of future changes caused by environmental factors or human activities. Sampling was conducted during hydroacoustic surveys with mid water trawling plus a few purse seine operations between 10 m and 100 m depth. A total of 86 species were collected.
Highlights
The Southeastern Brazilian Bight (SBB) comprises the area between 22°S (Cabo Frio) and 28°30’S (Cabo de Santa Marta Grande) (Matsuura, 1986)
This paper is the first to compile all the records of the species collected during the hydroacoustic surveys of the ECOSAR Program including geo-referenced data and the local depth of capture
Soares et al (2005) published part of the species composition of ECOSAR cruises II and III, in order to describe the echo records detected during July and November of 1995 and Vaz-dos-Santos & Rossi-Wongtschowski (2013) presented the length-weight relationships of the main species caught during ECOSAR IV to VII cruises
Summary
The Southeastern Brazilian Bight (SBB) comprises the area between 22°S (Cabo Frio) and 28°30’S (Cabo de Santa Marta Grande) (Matsuura, 1986). These surveys were concentrated south of 23°S and showed that the main small pelagic species in the SBB was the sardine, Sardinella brasiliensis, and, the anchovy, En‐ graulis anchoita, in the southern region (29°S‐34°S).
