The Brazilian sardine (Sardinella brasiliensis) supports the most important pelagic fishery in the southeast-south Brazil. The first studies on the population structure of S. brasiliensis suggested the existence of two stocks taking into account distinct regional somatic growth rates and spawning areas.

Characteristic Levels of Some Heavy Metals from Brazilian Canned Sardines (Sardinella brasiliensis)
Journal of Food Composition and Analysis, 2001Abstract The total concentration of metals Cu, Fe, Mn, Zn, Sn, Cd, Cr and Pb were determined in different brands of sardines canned in soybean oil and tomato sauce, commercialized in Brazil. The sample was dissolved after wet digestion with acids and the measurements were done by flame atomic absorption spectrometer (AAS).

This paper establishes the spawning habitat of the Brazilian sardine Sardinella brasiliensis and investigates the spatial variability of egg density and its relation with oceanographic conditions in the shelf of the south‐east Brazil Bight (SBB). The spawning habitats of S.

A rule-based model was built in order to analyse the effects of environmental variables (wind stress, Ekman transport, turbulence, and sea surface temperature [SST]) on the recruitment of the Brazilian sardine Sardinella brasiliensis. The purpose of modelling was (1) to test the optimal environmental window hypothesis (characterised by ‘dome-shape ...

Journal of Fish Biology, 1988
Biological data, size frequency distribution of intraovarian oocytes, maturity indices and histological observations of the gonads were used to assess the spawning cycle of S. brasiliensis, sampled September 1981–August 1982 throughout the main fishing area off the Brazilian coast (22°S to 28°S).

Biomass assessment of small pelagic fish stocks with acoustics depends on the use of scientific echo sounders that transmit/receive acoustical energy, quantify the echoes and generate the parameter Nautical Area Scattering Coefficient (NASC), proportional to the density of the live targets detected in the water column and within the acoustic beam.

Recent estimates of the size at first maturity (L50) of Sardinella brasiliensis showed contradictory results with a decreasing in the fish stock biomass encompassed by increasing values of L50. The methodological approach used hereby allowed to separate sardines classified in the virginal maturity stage from those categorized in the recovery stage, and
