I'm not normally any big fan of hunting, but when it comes to non-native feral pigs I think the open season on them should run 13 months a year. They can do horrible things to the local environment, tearing up the soil and native species and otherwise disrupting the ecosystem. To be honest, I've never really seen any evidence of a large wild hog population in CR, but we have PLENTY of them here in Florida. Why don't you come down here instead and shoot as many as you like.
BTW, I just tried doing a little research for you. I only found 2 semi-relevant references. The first referred to a TURTLE hunting season that ran July 1st through August 31st, but that was an old (1997) article and indicated that things were in motion even way back then to tighten the rules even further. The second short reference was in an article in the October 2007 Sports Afield which said:

If I read that correctly, the lack of game regulations has effectively banned all LEGAL hunting. Of course, there is still plenty of illegal hunting (aka poaching) done in or around the national parks by local residents. However, as a foreigner I would seriously advice you stay away from that as I'm sure the book would be thrown at you even if it was just a few wild pigs.
