Risks Associated With Too Much Vitamin E. Except for an anticoagulant effect, vitamin E has no known toxicity or side effects. There was a meta-analysis conducted by John Hopkins in 2004 that raised some concern about higher daily intakes, but this was most likely associated with pre-existing health conditions.
BUT-those four pike averaged 7 pounds each. That's 28 pounds of northern pike in a 3-acre pond, or nearly 10 pounds/acre of water. Compared to waters across North America, that is a high biomass (poundage) of northern pike. But, think about that. Four fish lived in an area bigger than three football fields.
Big northern pike eat large fish and a lot of fish, and so fish managers long thought that an abundance of northern pike would limit panfish numbers, preventing the stunting common in many lakes. As in Horseshoe Lake, stocking northern pike to control panfish can backfire. In fact, we have little evidence that an abundance of northern pike (or muskie) can prevent a proliferation of small sunfish. Apparently, sunfish are too prolific and too adept at hiding in thick cover to be controlled by northern pike.
