Don't doubt it-- fishing is one the list as well, according to a source. The following is from the Congressional Sportsmens Foundation media advisory:

Two Largest Animal Rights Groups to Merge

The Humane Society of the United States plans to merge with the Fund for Animals, forming a new advocacy organization and lobbying arm that they hope will have greater clout for animal rights issues. The newly formed group will be based in Washington but maintain a large office in Gaithersburg. It will have roughly 350 workers and a budget of $95 million next year. It will also include a lobbying section that both groups expect will have more freedom to push the group's agenda in Washington and state capitals, officials said. The new organization will focus on four major issues - fur, sport hunting, factory farming, and animal cruelty issues such as cock fighting and dog fighting.

This is scary stuff. These groups often get the most attention, which can equate to $$$, by doing the most outrageous things.

I would think fishing should be way down on their hit list, but it can get to the top quickly if they see a way to get some attention and make a point.
