Got a problem...

[fisherman123]

I live near a pond and go fishing there about 3 times a week. Ive been going for about 2 years and its been great. Recently an alligator got in and all the blue gill have been disapearing and i think theres even less bass. Its getting harder and harder for me to catch a bass when i use to catch about 10 a day now im lucky to catch 1 or 2. Im not sure if the alligator is eating all the fish or there just not biting anymore. I still see them jumping so i know some are there. I always used watermelon see worms and they stopped working then i tried some lures and that didnt work eathier. I think Im going to try to go early in the morning and use a top water. Then mayby a spinner. I also saw a gar in the pond not sure if that each the fish. I called to get the alligator removed but its under 4 ft in leangth so they wont take it. I dont have any other ponds or lakes near me and this one is so local i just walk there. Not sure what to do any help is apreciated.
