Releasing Non Native Fish Into Reservoirs

The bass populations are being affected but trying to pinpoint a specific reason is, at best, a shot in the dark. Consider this:

-Recent hurricanes have adversely affected gov't fisheries tasked with seeding sportfish fry all over the state.
-Last years historic freeze wiped out many ecosystems of both invasive and native species.
-Nutria and other herbivorous invasives have remodeled ecosystems affecting local food chains.
-Land development, agriculture, damming, and available groundwater resources continue to nibble away at surviving ecosystems.
-Even with current practices of catch-and-release, steel weights, and barbless hooks, native populations have to contend with hundreds of years of pollutants left in their waterways from old practices of cut lines, lead weights, trash thrown overboard (including oil cans, lead batteries, etc).

Basically, ask 10 people for a specific reason that bass populations appear to be on the decrease and you'll get 10 different responses due to all of the pressures placed on their ecosystems.

And, I have yet to hear or read from a credible source that there is, in fact, a hybridization success between Micropterus sp. and Cichla sp.
 
I have written a report at school on NOT realising non native fish into the wild. All the fish native fish in all the waters are ment to be so that there can be a perfect ecosystem. Man can't make a better ecosystem than nature. No man made aquarium or pond can beat nature.
 
gobeys and zebras are owning the great lakes its brutal.... Saying let nature take its course is stupid. Its like taking a bunch of wrestlers and making them kickbox...They wont do very well at all ! lol Just because they can fight in the same ring doesnt mean they should !
 
A few years back there was this small pond at the local school where i would fish for bass. I'd pull out one LMB after another and those that fished for sunnies would do so as well. One summer, i started seeing tiger oscars in the pond and even hooked a few. Not sure how many there were but there were at least a few and they either outcompeted the bass (doubtful) or a disease killed them. Needless to say, they died when winter came, but the damage was done and there are either no LMB's in that pond or there is a very very small, recovering population that i dont know about.

I can't say for sure that the two events were a result of cause and effect, but thats the way the people who fished the pond interpreted what happened and they did happen to be very closely correlated.
