Hi Dr, spoke to a friend, he thinks fish might have been injured or even shot by spearo, and thats what created the clotted bloody putty in the flesh, was about 5 cm from stomach cavity next to spine, allready took off the skin so I couldnt check for damage or markings.
Ja I saw millions of blaasoppies on the currentbreak feeding on baitfish scraps below the tail, very interesting indeed!
