<human>: So, to give some context, my family has a large Louisiana crayfish boil every year. Everyone in the family shows up, and a lot of family friends show up too. There's drinking, catching up with old friends, and a lot of food. But I never ate the crayfish, because the way they squirmed when getting put in the boiling water made me think that they were in pain. One year, I found a few uneaten crayfish at the bottom of the net bag that nobody was thinking of boiling. So, like the good Samaritan I am, I decided to give them a bowl filled with water to stay in and took them home with me. Eventually, I put them into a river that connected to the Columbia by my house. But they turned dark blue in the frigid water, so I thought they were probably going to die. Only a few years later (actually today) did I learn that the Red swamp crayfish, or the ones that my family used for the yearly boil, had started to multiply and out compete the smaller and less aggressive Northwestern Crayfish. I know it probably wasn't all me, but now there's a ban on importing crayfish into Washington and there's an increasing population of the crayfish we just so happened to use that's harming our normal crayfish population.

Condense the text into a few key points
<bot>: I accidentally helped to put a non-native crayfish into the Columbia River that's out competing the other, native crayfish.
