We are traveling overnight from Magnetic Island to Fitzroy Island. We have an overcast day with minimal wind. We have been lucky enough to catch about 5 fish. We do not know what they are so I would appreciate a little help from any fisherman. I think it is a type of mackerel. It has a band of coloration along the upper body that goes from behind the head and gills to about half way back its body. There are also a few spots along the side. I will send a photo. Bob
