Yea release all those that look like that - a very shinny white bass (he has been working hard - to hard). Plus he is stunted - he will never reach full maturity. And if you catch a skinny fish - they are not very good to eat - at all (they are sick to begin with).
If you released it - I hope he makes it (and recovered).
Good luck little buddy – I hope you made it (All the way back - to health and happiness and reproduction).
It is beyond any point of discussion, a white bass. I have caught many like that over the years. the type of water it comes from determines what shades of grey/white/green will stand out. i have caught A LOT of sandies/whites over the years that look like that one.
