Abstract: The temporal variability of energetic reserves of zooplankton in the eutrophic Pampulha reservoir was investigated during two successive annual cycles. The effects of dominance of large filter-feeding cladocerans (Daphnia) and the occurrence of massive blooms of the cyanobacteria Microcystis on the energetic reserves of zooplankton were tested. This study showed that phytoplankton composition has a greater effect on energetic reserves of zooplankton. Some associations between lipid levels and the specific comp… Show more

“…Organic fertilization is also known to promote the growth of smaller sized zooplankton especially the rotifers (Okojin and Obi, 1999) as well as other micro-zooplankton such as protozoans and copepod nauplii (Pinto-Coelho et al, 2005) which usually dominate eutrophic waters. This explains the abundance of rotifer group followed by the copepods throughout the period of study.…”

“…In particular when the mesh <200μm is used, the high biomass of phytoplankton such as cyanobacteria colonies and/or filaments often impair filtration of large volumes of water. In these environments, the most used strategy for zooplankton sampling has been the collection of a small volume of water for further filtration, as in the studies of and Branco et al (2002) in the Funil reservoir (20l), Branco and Senna (1996) in lake Paranoá (20l) or by the Schindler-Patalas trap (5.1l) as in the study of Pinto-Coelho et al (2005) in the Pampulha reservoir. However, in addition to the low volume, another question has been considered Schwoerbel (1970) when using collection by bottles, buckets or traps that although efficient in collecting in specific strata of water column, provides a random sample from a part of the water with obvious loss of plankton nearby.…”

“…Studies of the limnetic zooplankton in Brazilian natural lakes and reservoirs have been done using several sampling strategies such as collecting a known volume of sub-surface water by bucket or by bottle-sampler and filtration through a plankton net , Almeida et al 2006, Peixoto et al 2008, Nadai and Henry 2009, collecting with a suction pump , Takahashi et al 2005, Santos-Wisniewski and Rocha 2007, Serafim-Jr et al 2010, sampling at several depths using a Van Dorn bottle followed by filtration (Starling 2000, Maia-Barbosa et al 2003, Keppeler 2003, collection by vertical hauls with a plankton net at specific layers of the water column (Maia- Barbosa and Bozelli 2005, Sendacz et al 2006, Nogueira et al 2008, Simões and Sonoda 2009, Silva et al 2014, horizontal hauls at surface (Waichman et al 2002) or sampling using a Schindler-Patalas trap (Pinto-Coelho et al 2005, Bezerra-Neto et al 2009. These varieties of techniques are frequently also associated to personal preferences, system constraints and the objectives of different zooplankton community studies (Mack et al 2012).…”
