Hunting and Fishing

Q: Is it permissible in Islam to release a fish after having caught it?

Q:

1. Are we allowed to use real dead fish as bait when fishing? Meaning, not the rubber bait, bait like sardines, etc. 

2. Are we also allowed to catch and release fish?

3. If 'no' for the above question, the law says that certain fish must be a certain length and they should not be endangered, etc. and if they don't meet those requirements they must be released, or else you can get fined if caught. So if the answer is 'no' for question 2 then what should we do. Will we be sinful if we release the fish once we caught it, because you don't really know what size fish and species you catching until you caught it.
