Tuna But Which One?


TunaSickle

Question

Hi all,

I've been catching these in the past few days around the mouth of Pittwater.

Are they Mack Tuna or Frigate Tuna (Frigate Mackeral)?

(The bottom fish in the top picture is a Tailor)

Thanks all

Ashley

Mackerel Tuna:

Most but not all have one to nine, and sometimes even more, small black spots or blotches between the pelvic fin and the pectoral fin. They can also be distinguished from the Frigate Mackerel by the lack of space between the two dorsal fins, the Mackerel Tunas first dorsal fin extends nearly all the way to the second dorsal fin where as the Frigate Mackerel's first dorsal fin is distinctly separate from the second dorsal fin.
