EFFECTS OF 1080 in Water and Aquatic Life

1080 and Water and Aquatic life:


Doc & Landcare Research claim that 1080 does not harm fish and other aquatic creatures.

However during a RNZSPCA visit from American forensic scientist and entomologist (insects) Dr. Jason Byrd, a member of the American SPCA who investigates crime scene forensic cases, and is employed by a university in Florida.

He raised similar concerns to the late Mike Meads (who was also an entomologist), in regard to the Krebs cycle and how the Krebs cycle is a process used by most organisms. Even the ones that break 1080 down. He suggested that when the 1080 is broken down it is possibly changed into some other toxic entity.

Dr Byrd pointed out that our native koura, among other things, will most likely be affected, and killed by 1080, if enough is eaten - whereas our DoC denies 1080 harms koura. DoC claims koura can eat 1080, and just pass it out with no harm being done. We dispute this, and believe it should be researched further, as where koura are present, they are poisoned in all streams 3 metres in width and under, on all aerial drops where cereal bait is used. They are also a food source for other animals and fish.

Trout Mass-Poisoned in New Zealand


Published on Sep 29, 2014

New Zealand has some of the best trout fishing in the world!

Every year, thousands of international visitors wade pristine rivers in search of the freshwater game fish.



From www.FishnHunt.co.nz - 1080 in water ways?

Dec 15th, 2014 at 10:21pm 

Hi, I'm sure this has been covered over and over again but I would like some info please. During the weekend I went for a hunt, after 3 hours walk in pissing rain up a river gorge I came across some fresh 1080 bait F#@K it all. I found bait right on the edge of the river and obviously it had been dropped straight down the river bed.  Also I did not see any signs indicating that there had been a 1080 drop. Is this worth reporting? To who? Are D.O.C required to put up signs? And are they allowed to drop bait in water ways?. Thanks


1080 prompts trout warning


STUFF.CO.NZ 26.09.2014

Anglers are being warned to avoid eating fish caught in back country waters as they could be tainted by 1080 poison.

The Department of Conservation plans to aerially drop 1080 poison across 700,000 hectares of conservation land, mostly in the South Island, to reduce rodent numbers. 

Fishing groups expressed concerns that mice - which were often eaten by trout - could carry sub-lethal amounts of 1080, posing a food safety risk for humans.

DOC commissioned independent research into the risk, finding 1080 levels in trout flesh were significantly higher than recognised food safety guidelines. 

Fish & Game New Zealand chief executive Bryce Johnson said the results were "not a good look" for New Zealand's so-called 100 per cent pure environmental brand.  

“Anglers fishing back country waters, including overseas anglers who come here because of the trout fishery’s international reputation, have always been able to assume that it is totally safe to catch a trout and eat it. Sadly, this turns that over," he said.

Government Misleading Public Over 1080 and Trout

Monday, 13 October 2014, 3:38 pm


Council of Outdoor Recreation Associations of New Zealand

The government, the Minister and Ministry of Primary Industries Report playing down of 1080 in trout is both deceptive and misleading says a national outdoor recreation organisation.

Bill Benfield, co-chairman of the Council of Outdoor Recreation Associations of NZ (CORANZ) said closer analysis of MPI's report shows the trout with 1080 residues are more dangerous to human health than was previously claimed.

"In a deft bit of sleight of hand, the MPI report diverts attention from the food to the human subject. In fact, by their own figures, the MPI shows that the food, the trout flesh from the Cawthron studies containing 4.7mg/kg exceeds New Zealand Food Safety Authority figures of 0.001mg/kg of 1080 by a staggering 4700 times," he said.

The trout flesh even exceeded the bottom line for human risk, the toxicological end point of 0.075mg/kg per day, by no less than 62.5 times.

"The fish is highly toxic and a human health hazard" he said.

CORANZ believed there were other potentially more dangerous paths for 1080 into the human food chain than mice, such as a trout eating a fresh water crayfish (koura) that do eat 1080 baits.

"Science several years ago revealed other dangerous levels of 1080 in freshwater aquatic life, showing 1080 can get into the human food chain via koura and eels as well as trout," said Bill Benfield.


A 2006 study on koura showed dangerous levels of poison in their flesh while a 2005 Landcare Research study on eels which scavenge poisoned animals in the water showed their flesh will substantially exceed minimum food safety standards.

"CORANZ believes all the New Zealand Government agencies and the Ministers involved have a duty to advise the public that eels, koura and trout can contain dangerous residues of 1080 in catchments where 1080 is being used," he said.
