More than 1000 snapper have been found floating off Northland's coast, mystifying Ministry of Fisheries staff. Some of the fish, founding off Ruakaka, 29km southeast of Whangarei, by recreational fisherman on Saturday, were sent to National Institute of Water and Atmospheric Research (Niwa) for testing, the Northern Advocate reported. MFish district compliance manager for Northland Darren Edwards said the fish were alive but "looked as if they had been stunned".
The final section of fish reaction is 'electronarcosis'. With DC this sub-section is known as galvanonarcosis. Fish become dazed and immobile and show little or no response to alternative stimuli. At this point the fish will cease to breathe for short periods. Depending on species, some will sink (eels, bullheads, initially carp and zander) and others will float (bream, pike, carp after a short period and zander after a couple of minutes but float for a long period there after). This is a critical point as long periods in the field can cause death. Conversely, shorter periods are ideal as fish will recover and return to normal.
Of course it's an offence for a commercial fisherman to land a Snapper catch without owning Quota for the fish so sometimes fish just get dumped after being caught because the fines are too severe.

I don't think they would catch 1000 of them then decide to dump them, I wouldn't have caught them in the first place if i know that they needed a quota.
