"I�d estimate risk of predation from largemouth as follows:
5 inch wiper--80% over one year in presence of LMB
6 inch wiper--65% over one year in presence of LMB
7 inch wiper--45% over one year in presence of LMB
8 inch wiper--15% over one year in presence of LMB
9 inch wiper--negligible mortality.
