Diurnal variation of zooplankton biochemical composition and biomass in plankton production tanks
(2006-04-01)
The nutritional value of zooplankton (lipid and phosphorus contents) was analyzed in outdoor, plankton-culture tanks, to monitor the effects of diurnal variation and fertilization. Total lipid contents were significantly ...

Decadal change in zooplankton seasonal succession in the Bahía Blanca estuary, Argentina, following introduction of two zooplankton species
(Oxford University Press, 2004-12)
Seasonal zooplankton succession (mainly of the mesozooplankton) in the inner zone of Bahı ́a Blanca estuary during the period 1990–1991 was compared to that from the period 1979–1980 in order to detect changes having taken ...
Diurnal changes in zooplankton respiration rates and the phytoplankton activity in two Chilean lakes
(Kluwer Academic Publishers, 1989)
Respiration rates of natural zooplankton communities were measured for diel cycles in two lakes. Distinct diurnal cycles were observed in Embalse Rapel with high respiratory rates for the spring cladoceran dominated ...
Zooplankton assemblage of Oyun Reservoir, Offa, Nigeria
(Universidad de Costa Rica, 2009)
Zooplankton community and tributary effects in free-flowing section downstream a large tropical reservoir
(2016-04-01)
This study aimed to evaluate the zooplankton structures and environmental conditions in the interface reservoir-downstream river and tributaries. Zooplankton structure and environmental variables were analyzed in the ...
Frozen zooplankton is efficient as natural food during pirarucu Arapaima gigas weaning
(Wiley-Blackwell, 2021-04-06)
The commercial production of carnivorous fish depends on the feed training that can be made through the direct transition from natural food to inert food. As using live natural food requires care in production, alternative ...
