I am part of the fishing club here at Longwood University in VA.
I understand the difficulties of having a fishing club being that it can possibly fall into a few different categories. Some schools (such as larger universities that compete on a national level, FLW, etc..) have funded teams that are official in every regard and offer scholarships and funds for equipment/boats etc... Then you have clubs that are merely a group of people who share the same interest of fishing and get together to fish and hang out. Our club falls somewhere in between and we are currently evolving into a more recreational club, and only a few of our anglers compete representing the school.
What I suggest you do is figure out what your goals are for the club as far as the things you actually do together. Dont be afraid to start small and grow. I would caution you against going straight for competing FLW or similar tournaments. Perhaps start as an interest club and organize meeting to discuss fishing, plan trips (even if its just a group outing to local waters for a day), and plan club events and fundraising.
Also, this might sound stupid, but I always find people who want to fish but dont know where to go since they moved to school! Talk to them and get them involved. Weve gained alot of interest and members just by randoms spotting me with my fishing gear or up at the lake, and I tell them to come check us out. Word of mouth is a powerful thing in college. Sometimes people are reluctant to get involved until you directly offer them a spot. We dont need anyone to have a bass fishing resume to fish with us. They ask me "What do I have to do to join?" and all I say is your in the club now! Meeting is this wednesday!
We do things like Relay for Life, host small tournaments on local lakes, go to fishing shows and expos together, fish small tournaments, and we just fish together! It is a great thing to be a part of and we have alot more interest than expected. We try to be as welcoming to beginners as we can by getting them involved with helping at weigh ins, and car pooling to Bass Pro and the expos etc..
I hope this helps! Just remember that at the end of the day even if its not something huge, having a club that simply enjoys fishing together and hanging out is the way to start things.
***Also, I forgot to mention: Find the organization at your school that handles clubs/club sports and do it through them. Here at LU is is the Sports Club Council. So we have meetings with them for budget, community service, etc... We are at the same level as club baseball, rugby, equestrian, etc... any sports that arent NCAA. Most likely, that organization will welcome a new club and actually assist you by providing publicity through thier FB page and such. Hope this helps!
