I like fishing vessels
Me too, I use them to catch fish in the sea.
I use to catch wild atlantic salmon and tuna 
Atlantic salmon? Are you referring to the ray-finned fish in the family Salmonidae?
I am referring to salmon 
Yes they are intensively farmed in many parts of the world because they are delicious!
That is true. They have red flesh 
That is because they hatch in fresh water and migrate to the ocean. 
That is true. They also very tasty 
Thats exactly why many species of salmon have been introduced into non-native environments. SO that more people can enjoy them!
