Hard to say from the condition and photos but "look" like could be brim(small snapper) and blue cod so yes eating fish.
Second look and Id say the long skinny ones are blue cod as the skin is attached at the tail, most people do it this way. Fillet off and leave attached at tail,a quick score each side of the pin bones and rip of the fillet leaving all the bones attached to the skin.
The others might be jock stewarts/Maori chiefs/red perch.
