This study investigates the use of X-ray technique
in estimating the gastric emptying time in whiting (Merlangius merlangus
L.) fed in the laboratory conditions. All the experimental fish was
fed to satiation with their natural prey sprats. The disperse type radio-opaque
compound Barium Sulphate (BaSO4) paste was pre-injected in
the body cavity of sprats in proportion to the body weight (0.1 to 0.15
ml/g sprat) prior to the experimental feeding. The BaSO4
paste was found suitable to portray the actual movement of food/prey
items over different time since feeding that for fish that took larger
satiation meal required longer time to empty the stomach. Results of
this study disapproved the earlier claimed that the gastric emptying
times (GET) remained constant as meal size increased. Results on modeling
of satiation feeding were also discussed.
