Nitrogen excretion and the cardiorespiratory physiology of the gulf toadfish, Opsanus beta.

Abstract

Gulf toadfish, Opsanus beta, are facultatively ureotelic and can excrete the majority of their nitrogenous waste as urea. Urea excretion occurs in "pulses." The hypothesis that pulsatile urea excretion reflects sudden, transient, generalized increases in the branchial conductance was investigated by the simultaneous monitoring of cardiorespiratory variables, oxygen uptake, and whole-body urea, ammonia, and/or 3H2O effluxes. The direct …
