Bass found in my pond?

We bought a House for 3 years now. When we moved in, it was Late summer. Getting cold toward falls already. There is a medium sized pond that was at our backyard. We discovered Mosquito Fishes, Koi, Goldfishes, Cobra Guppies, Sucker Fishes, and Oscar fishes.

The fishes are so big, we tried to net them and etc. Since water is too deep, we used Barb less Hooks to fish the big ones out!

This year, there isn't much rain, and most fishes are not coming out to the sunshine as usual anymore....

We'ved fished them for a little over 2 years now. Yesterday we caught some "Black Bass"

it is a Fish and Game Wildlife Fish!!!!!

We continued to catch more of this species, and contacted a Pond Specialist to check up on the pond.

He says there isn't a water stream that flows into the pond. There is no other explanation as to maybe if the former people who lived here stocked the fish in this pond.

One reason why the Aquarium fishes doesn't come anymore is because the bass is eating them.

We found Baby Gold fishes in their stomach. Especially the Guppies and Mosquito fishes.

QUESTION IS:::::::::::

How'd they get here?

Our back yard is Fenced with Barbed-wires on the top of the fences.

No one could of stocked them in. Unless the former people.

But if so, we could of caught some "2 years ago"?????

We used Same bait. :)

No fish was killed or tortured as animal curtly. All fish hooked is stocked in large containers of more than 200 gallon tanks and treated with certified Chemicals to help heal their mouth faster.

Sold to fish keepers.
