Hi, This is my first post and I haven't actually been fishing that much before recently. I've just started to get into it more. I didn't know whether to post this is freshwater or saltwater, but I thought brackish estuary fishing is closer to saltwater. Anyway, I'm looking for some help with an ID on the Bream i caught tonight. I can't tell whether its yellowfin or blackfin bream. The information I have tells me that yellowfin are not common around the Glenelg River in Victoria, where I caught this, however it seems to have a yellowish, kind-of, set of fins. At least they are not totally grey black.. I have also heard of hybrids. But generally I have heard that blacks are more common in this area. Any one know what it is?
