Relationship Between Ichthyoplankton Abundance and Associated Zooplankton Biomass in the Shelf Waters off Argentina

摘要: AbstractZooplankton and ichthyoplankton volumes, larval fish abundance, were determined for 689 stations established during 18 exploratory cruises in the sea off Argentina. Zooplankton density distributions throughout year relation to water temperature are presented. The equation Y = 5.89 × 0.78 was calculated used transform data on volumes obtained with a 505-μ-mesh net compared then those 330-μ-mesh net. Strong negative correlations observed between occupied by eggs of zooplanktophagous species associated zooplankton biomass: Micromesistius australis (r =—0.92); Sprattus fuegensis =—0.82); Engraulis anchoita =—0.94). No significant relationships egg ichthyophagous biomass, larvae abundance though this case general positive tendency observed. abundances two fishin...
