The effects of greem and blue-green algal diets on the reproductive rate of the rotifer Brachionus plicatilis

, : The effects of greem and blue-green algal diets on the reproductive rate of the rotifer Brachionus plicatilis. Aquaculture, 311: 21-30

The reproductive rate of the rotifer B. plicatilis cultured on a variety of diets was investigated. Unialgal and mixed diets of the green alga Chlorella and the blue-green alga Schizothrix were compared. The rotifer reproductive rate was an average of 2.7 times higher on a mixed diet of Chlorella and Schizothrix than on either Chlorella or Schizothrix as a unialgal diet. Enhancement of the rotifer reproductive rate was not observed on a mixed diet of Chlorella and Dunaliella compared with a unialgal diet of Chorella. Ingestion of Schizothrix was not required for enhancement of rotifer reproduction. The enhancing factor is a heat labile substance.

As the vascular endothelium has multiple functions, including regulation of vascular tone, it may play a role in the pathophysiology of orthostatic intolerance. We investigated the effect of orthostasis on endothelial function using EndoPAT®, a n...
