XP is multiplied by 2.2 if you also catch a treasure chest, by 2.4 if the catch was "perfect" and by 5 if the catch was a Legendary fish.  These multiplications stack, and are performed in order (first treasure chest, then perfect, then Legendary).   

XP is multiplied by 2.2 if you also catch a treasure chest, by 2.4 if the catch was "perfect" and by 5 if the catch was a Legendary fish.  These multiplications stack, and are performed in order (first treasure chest, then perfect, then Legendary).   

For example, catching a perfect Sardine with a treasure chest would net you 13 * 2.2 =  28.6 (truncated to 28) XP, then 28 * 2.4 = 67.2 (truncated to 67) XP.
