Cladocerans as an Ideal Live-Food for Fish Larviculture Towards Aquaculture Sustainability
Aquaculture remains one of the fastest-growing food-producing sectors, challenges for the development of a sustainable and species diverse aquaculture industry is lack of suitable live feeds at the larviculture phase.

Brazilian Journal of Biology, 2001 The accumulation of lipid reserves was investigated in two common cladoceran species typical of neotropical freshwaters. Experiments were performed in order to measure differential accumulation of lipid reserves in response to two algal diets, S ...

Cladoceran assemblage in a mesotrophic reservoir
, 2003 Cladoceran assemblage patterns were investigated in a meso-eulrophic reservoir from January 2000 till December 2002. Trends of environmental factors (water temperature, conductivity, pH, and nutrient concentrations), as well as of biotic factors (availability of potentially edible phytoplankton and densities of herbivorous and carnivorous copepods ...

Cost of reproduction in selected species of zooplankton (rotifers and cladocerans)
, 2002 Reproduction is an energetically costly biological process. Among the freshwater zooplankton, rotifers and cladocerans reproduce parthenogenetically and the cost of reproduction can be estimated using the life table data from demographic studies. Reduced

The biokinetics of calcium and its interaction with cadmium in freshwater cladocerans
, 2010 The calcium (Ca) biokinetics and the protective effects of Ca against the bioaccumulation and toxicity of cadmium (Cd) were investigated in the freshwater cladocerans. Water was the dominant source of Ca for cladocerans.

, 1997 Eutrophication in Tjeukemeer involved a gradual increase in chlorophyll concentrations from ca. 30 mg m⁻³ in 1968-69 to 125 mg m⁻³ in 1976. From 1976 onwards, chlorophyll concentrations remained at a high level fluctuating between 100-225 mg m⁻³ ...

Ecological IndicatorsAquatic biodiversity is essential for maintaining lake ecosystem health, yet large-scale studies linking zooplankton communities, particularly cladocerans to environmental gradients remain limited in the world's most populous heartland (Asia).

, 1997 The role of large laboratory grown food competitors of the genus Daphnia as well as the predation impact of Chaoborus on the cladoceran community of an eutrophic lake was assessed in five in situ enclosure experiments.

Hormonal induction of undescribed males resolves cryptic species of cladocerans [PDF]
, 2006 Cyclic parthenogens have a mixed breeding system with both meiotic and ameiotic eggs. Although investment in sexual stages is often synchronized with seasonal cycles, the degree of investment is a quantitative trait associated with habitat instability ...

Is competition an interaction as relevant as predation for tropical planktonic cladocerans?
, 2018 Aim To test the relevance of competition and predation for the two most abundant and frequent cladoceran populations, the medium-sized Ceriodaphnia richardi Sars, 1901 and the large-sized Daphnia gessneri Herbst, 1967, in a tropical shallow lake ...
