Title: The effect of emersion and handling on the nitrogen excretion rates of <i>Clarias gariepinus</i>
Abstract: African catfish Clarias gariepinus (x̃=119.9&30.6 g) were exposed to periods of emersion (5, 30, 60, 90 and 180 min) and the ammonia and nitrogen excretion rates measured following re‐immersion. Immediately following re‐immersion (0–30 min), the ammonia excretion and relative ammonia excretion was greatest for the 5‐min emersion gro up. Exposure to extended periods of emersion resulted in a decrease in total nitrogen excretion, notably ammonia excretion, although no significant changes were observed in the non‐ammonia component of C. gariepinus .
