I love summer.  I spend a lot of time on my fishing boat.  It is a vessel that we use to catch fish on the lake or river.
Do you eat the fish that you catch or throw them back in the water?
I usually cook them.  We do a lot of fly fishing.  It is a method where you use an artificial fly to lure the fish
What type of fish do you usually catch?
We like to catch salmon if we are catch and release fishing.  Many salmon and trout rivers are actually catch and release now
Oh wow, I didn't know that.  Why don't they like you to keep them?  
A lot of it is due to protecting the species.  For instance, in the UK, they perform catch and release in order to protect target species of fish from diminishing 
Oh ok, that makes sense.  How did you get into fly fishing?
