As well as being voracious predators, pike are fertile fish. That means that they can establish a breeding population wherever they are planted. Hybrids cannot do that. The hybrids will initially compete with other populations for food, but because their population cannot grow they will eventually be caught or die out. Ice fishing during the winter.
Many states stock a variety of hybrids to accomplish various fisheries management goals.
We are only stocking hybrids in landlocked lakes. If these fish do not perform as intended, we will stop producing them. Those that have already been stocked will eventually die out and there will be no replacements. The hybrids are a salmon, and we expect that they act like other landlocked salmon. If your flies or lures look like their food, they will certainly hit on them.
