The accumulation of bacteria in Brachionus plicatilis and Artemia franciscana during a Ž . short-term incubation was quantified using immunocolony blot ICB and an enzyme-linked Ž . immunosorbent assay ELISA . Four bacterial strains, isolated from turbot and halibut, were Ž 7 y1. grazed effectively by both species when given at high concentrations G5=10 bacteria ml . B. plicatilis accumulated 21...

Harmful algal blooms have caused enormous damage to the marine ecosystem and the coastal economy in China. In this paper, a bacterial strain B1, which had strong algicidal activity against Phaeocystis globosa, was isolated from the coastal waters of Zhuhai in China. The strain B1 was identified as Bacillus sp. on the basis of 16S rDNA gene sequence and morphological characteristics. To evaluate...

The current state of the quantitative and qualitative development zooplankton in Kakhovka Reservoir is examined. species composition, representation taxonomic groups, number biomass summer period 2020–2021 were determined. average 2020 studied areas (Bilenke village, Bilenke-Malokaterynivka station, vicinity Malokaterynivka village) was 40.833 units/m3 with 0.245 g/m3, 2021 — 110,932 0.652 g/m3...

Spatial and temporal patterns in the distribution of the zooplankton in a tropical Man-made reservoirThol Bird Sanctuary were investigated for two consecutive years from September 2007 to August 2009. The zooplankton was sampled at two different zones of Thol wetland located 23 o 15’N and 72 o 30’E near Ahmedabad city of Gujarat state, India. Sixteen species of Rotifers rich in number of indivi...

1. The analysis of functional groups with a resolution to the individual species level is a basic requirement to better understand complex interactions in aquatic food webs. Species-specific stable isotope analyses are currently applied to analyse the trophic role of large zooplankton or fish species, but technical constraints complicate their application to smaller-sized plankton. 2. We invest...

In order to maintain rotifer populations during periods of low algal production, it is necessary to offer alternate diets, some of which include forms of preserved algae. The present work is based on the effect of live and dead Chlorella vulgaris on the population growth of Brachionus calyciflorus and Brachionus patulus. The experimental design consisted of three algal levels (0.5 x 10(6), 1.5 ...
