Chronic Effects of Bromate on Sexual Reproduction of Freshwater Rotifer Brachionus calyciflorus

Bulletin of Environmental Contamination and Toxicology, 2021
The effects of potassium bromate (KBrO3), sodium bromate (NaBrO3), and potassium bromide (KBr) on the sexual reproduction of the rotifer Brachionus calyciflorus were studied by 2-d population growth, 4-d sexual reproduction, and 7-d resting egg production tests.

Extrapolation of Metal Toxicity Data for the Rotifer Brachionus calyciflorus Using an Individual‐Based Population Model

Environmental Toxicology and Chemistry, 2023
Ecological risk assessment (ERA) of metals typically starts from standardized toxicity tests, the data from which are then extrapolated to derive safe concentrations for the envisioned protection goals.

Feeding in the rotifer Brachionus calyciflorus

Oecologia, 1977
Feeding behavior in B. calyciflorus was observed in both constrained and unconfined individuals. There are at least three mechanisms by which the ingestion of suspended particles may be regulated. First, the cirri of the pseudotrochus may be extended, allowing particles to enter the funnel-shaped buccal field, or they may be bent over medially, forming

Culture of the rotifer Brachionus calyciflorus Pallas

Aquaculture, 1992
Abstract Optimum conditions for raising the rotifer Brachionus calyciflorus Pallas were identified. A temperature of 30 °C and a food concentration of 10 7 cells/ml of the alga Chlorella vulgaris were identified as the most suitable conditions for culture of this rotifer. Maximum production was 81 080 rotifers/1 day −1 . The size and growth rate
