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).

2013 IEEE/OES Acoustics in Underwater Geosciences Symposium, 2013
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.

While nephrocalcinosis (kidney stones) is uncommon in wild teleost fish, various environmental and nutritional factors could lead to its occurrence in aquacultured fish. This study presents the first documented case of kidney stones in aquacultured Brazilian sardine (Sardinella brasiliensis).
