Abstract
African lungfish specimens, Protopterus annectens (Owen) (mean length 37.6 cm, and mean weight 379.5g) procured from Agulu lake, Nigeria, were exposed for one week to a complete aerial life outside water. This led to significant body weight reduction (due to dehydration) as well as significant rise in blood haematocrit (P <0.05). However there was significant reduction of blood pH (p < 0.05) due to increased production of H+ which was actively transported into the extracellular fluid.
