On Saturday 21 March 2009 Tim Connolly, Sara Dobson and myself went for a Kayak/walk at Ella Bay (North of the creek mouth) and we found the remains of a large Queensland Groper Epinephelus lanceolatus.

Here's photographs of this fish.

Its lower jaw had been damaged perhaps by someone removing a fish hook. It was concealed in the sand with only its head/spine visible.
Nearby at the creek/lagoon there was sign of recent fishing activity however this is not relevant as the carcass is well over a week old. As you are aware this species is a no take protected marine species so its death could be of interest to you and that is the reason for this email.
I am also aware that Queensland Gropers have been dying in this region due to a bacterial infection so perhaps this may be the cause of death though this would not explain the damage to the fish’s lower jaw.
Here's a relevant article from the Cairns Post regarding this matter.

The death of any protected marine species is significant especially within such an environmentally sensitive area. I hope this information is of some use. If you require further details or higher resolution photographs please feel free to contact me.
