BLOOD HAEMATOCRIT AND PH SHIFTS DUE TO TRANSFER OF THE AFRICAN LUNGFISH, PROTOPTERUS ANNECTENS FROM AN AQUATIC TO A COMPLETE AERIAL HABITAT

A.I. OKAFOR

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.
