Ventilation rate, gills

However, some effects are less intuitively obvious, and have been neglected. Unstirred layer formation can have large effects on solute transport, and, on a minute-by-minute basis, animals are constantly readjusting physiological systems (e.g. gill ventilation rate, blood flow) which will affect unstirred layer formation. Ventilation and blood flow are influenced by many environmental factors, but the interrelationship between environmentally induced cardiovascular adjustment, unstirred layer formation, and the cost of solute transport remain to be explored. 

Thomann et al. (1992) (see Table 9.4) and Morrison et al. (1996) (see Table 9.5) developed models that derive uptake and elimination rate constants based on physiological parameters such as gill ventilation rates, weights and lipid contents. The Thomann model has been... 

Thomann (1989) and Gobas (1993) have developed physiologically based kinetic models, including rate constants for chemical uptake and elimination based on physiological parameters such as gill ventilation rates, feeding rates and chemical assimilation rates as well as empirical correlations. Tables 9.6 and 9.7 list the model equations and parameters.
