No matter how they got in there they have affected the bass and bluegill. They spawn several times a year and are aggressive nest raiders themselves for the other species. They also compete with the bass and bluegill for the limited food supply. The only upside is that their young in turn are good food for the bigger bass.
DWR has put a mandatory keep and kill regulation in place for the tilapia in Blue Lake.
It is preferred to fish that area in colder months to avoid the bugs. Since the water stays warm all year it does not hurt the fishing...and it is a great place to go fishing without having to drill holes in the winter. Just be sure to stay close to your vehicle. Lots of vandalism and theft on unguarded cars and gear.
They are in the cichlid family, and from my experience with aquarium fish, are VERY aggressive. a Cichlid tank is just that, cichlids only. pretty exclusive club, very territorial. kinda like junk yard dogs.
Good thing is, cold water is a limiting factor.
The biggest population and the easiest to catch are the ones in the shallower "bluegill pond"...close to the road. The sizes go in cycles. Sometimes smaller than others, but looks like there are some big enough to justify a trip.
They are primarily vegetarian...and green peas do work. But in a competitive environment they eat anything that doesn't eat them first. The main food item in that water system is a small aquatic beetle. Even bass eat them. But fish eggs and small fry are on the menu for all species. A lot of the "regulars" from Wendover just soak a piece of crawler or fish a small jig with a bit of crawler for sweetener.
Light travels faster than sound.
So some people seem really bright until you hear them talk.
Not good to give advice on a forum that violates our local laws. For those who don't know, Paulpro lives in Florida and of course they have different laws than we do here in Utah.
Like they say in that informercial..Set It And Forget It!
A Bass a Day Keeps the Doctor Away..
