Import numbers rarely match the source exportersâ stats. Reasons for import-export statistical discrepancies include re-exports, time lags, misallocations, distinct trade reporting systems, different quantity measurements and country confidentiality rules. Also, transportation and insurance costs are sometimes added to import totals.
Northern pike are freshwater fish with elongated bodies and flattened, duckbill-shaped snouts. Their mouths comprise half the length of their head and are full of sharp teeth. Northern pike are dark green to gray in color on their backs and sides with rows of pale, oval spots (wavy lines in juveniles).
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.
