Biovolúmenes de zooplancton e ictioplancton en otoño 2014

open access: yes, 2018
ABSTRACT: During autumn 2014, between 03°30’S and 10°S, 94 zooplankton samples were collected using a Hensen net (300 μm) by vertical trawls 50 m deep to the surface. Biovolumes fluctuated between 0.5 and 50.0 mL/sample, with a mean of 10.9 mL/sample. Biovolumes between 5.1 and 10.0 mL/sample were more frequent (40.4%) than biovolumes larger than 20 mL/
