That looks definitely 'undersized' and should, therefore, be thrown back overboard asap, dead or alive. I'd then raise the anchor and scarper off to somewhere, anywhere, they aren't.

I prefer your other 'Catch-of-the-Day'. 

From FB; Seriously, it's one I haven't seen before, and it was caught as trawling by-catch in 360m off Eden. I asked Mark McGrouther of the Aust Museum, and Jeff Johnson of the Qld Museum.

The combined response is: "It is a species of Jellynose, family Ateleopodidae. Ateleopus occurs off the Qld & NSW coast but the species I am familiar with does not reach this size.
Another genus Ijimaia is rarely found off the southern coast, but does not seem a good match for this fish."
