ABSTRACT
Three glomerular filtration markers injected into Holthuisana transversa disappeared from the haemolymph at very different rates. Polyethylene glycol 4000 disappeared at a rate ca. 5 times faster than Cr-EDTA and ca. 15 times faster than inulin. Inulin and Cr-EDTA were excreted by the crab but only 5 % of the injected PEG 4000 left the body.
Inulin injected into the excretory organs was reabsorbed into the haemolymph.
The reliability of commonly used glomerular filtration rate markers as indicators of filtration in decapods is discussed.
