AB  - The morphometric status of the digestive tract of <I>Heterobranchus bidorsalis</I> juveniles exposed to graded concentrations of Bonny-Light Crude Oil (BLCO) was studied. The exposure of the fish to 1.00, 2.00, 4.00, 8.00 m L <SUP>1</SUP> and a control for 4 days toxicity period indicated that significant decreases (p< 0.05) in the widths and lengths of the Oesophagus (OES) Stomach (ST) and Intestine (INT) of the fish were BLCO concentrations dependent.  Increased  OES,  ST  and  INT  values  noticed within the first 14 days of the recovery period  implies  that   the  removal  of  the  oil  pollutant  from  the  ambient water chemistry probably rescucitated the component parts of the digestive tract of the fish both in length and in width. The magnitude of rescucitation of  these  component  parts improved between day 14 (5%) and day 42 (15%). This implies that the ability of <I>H. bidorsalis</I>  juveniles  to  recover  their  full  and inherent capacity to utilize ingested food after water pollution is time dependent.
