Intestine Length and Feeding Ecology of Freshwater
O. Ribble and Michael H. Smith
There is a significant relationship between the
intestine length (Y) and total body length (X) for 11 species of freshwater fish
variation exists about this relationship to indicate important differences among
the speciesí diets. The diets for each species, ranked on a Trophic Index scale
determined from literature data, are negatively rank order correlated with the
mean relative intestine lengths (r2=-0.67).
There is no significant rank order correlation between the Tropic Indices
determined from data or stomach contents and the mean relative intestine lengths
for fish from a single creek.
