Long-time Mannering Park resident Kevin Rixon doesn't claim to be a scientist, he just has a gut feeling that there's more to the recent fish kills in southern Lake Macquarie than meets the eye.
"I think there is a cover-up going on," Mr Rixon said at the local boat ramp where hundreds of dead fish, including mullet, bream, bat fish, whiting and a juvenile white spotted eagle ray, washed up on Wednesday.
