Blood Viscosity Measurements in Antarctic Fish Across Temperatures and Shear Rates

Antarctic and New Zealand fish species provide measurements of blood and plasma viscosity. Data includes comparisons between active and sedentary species and examines viscosity across temperatures from -2°C to +15°C and shear rates from 2.3/s to 450/s. The dataset was created by SCIOPS and last updated in December 1988.

Use Cases

• Model the relationship between viscosity and red blood cell concentration using data from Trematomus bernacchii.
• Compare blood viscosity trends between active and sedentary fish species across the measured temperature range.
• Analyze the effect of sampling stress on viscosity using data from chronically cannulated T. bernacchii.
• Characterize the viscosity of whole blood from channichthyid ice fish (Chionodraco kathleenae, Cryodraco antarcticus) against temperature and shear rate.

Strengths

• Viscosity measured across a wide temperature range from -2°C to +15°C.
• Shear rate varied across a broad spectrum from 2.3/s to 450/s.
• Includes data from multiple fish families (notothenioids, zoarcids, channichthyids) and a comparative species from New Zealand.

Limitations

• Dataset is temporally stale, with last update in 1988.
• Specific sample sizes, row counts, and column details are unknown.
• Geographic scope is limited to Antarctic species and one New Zealand comparative species.
