Need tips of spearfishing alberta/sask
 

Hey my brother in law and I are thinking of starting spearfishing this summer. Looking at the regs I realize you can't target most game fish here. In sask however you can go for whatever a hook and line fisherman can go for.
That being said, has anyone here attempted to spearfish here or in sask, and do you have any tips on how to do it successfully? Perhaps even when the best time of the year is for water clarity?

Thanks,

Will.
