Go to the Market Lane, there is a shop called Petpet Emporium, there they will sell you a fishing pole for 100 Park Points.
You have to buy a fishing pole from one of the stores and then go to a pond where you can see shadows of fish swimming and then click on the fish and your petpet should start fishing and catch the fish.
They are in the glowing lake in the wailing tunnels by where Jorguss the Giant Spyder lives. You need a fishing pole, though.
There is normally a fish vendor near the lake. Remove the fishing pole and talk to the fish vendor.

Treefish are in the water at Pukapooka Beach. You need a fishing pole from the Petpet Emporium in Market Lane to fish there. Put the fishing pole on and stand close to the Water in Pukapooka Beach where you see fish floating on the surface and if you put your mouse over that spot you should see a red and white fishing icon. Try fishing, if it does work, more to the next fish shadow on the water and try to catch that. You can get more tips from: http://petpetpark.jellyneo.net/go/activities/
