Minister makes wrong bluefin tuna and crayfish decisions
The Acting-Minister of Fisheries decision to increase the catch limit for the critically endangered southern bluefin
tuna and not to cut the catches of the overfished Gisborne or East Cape rock lobster has appalled the Environment and
Conservation Organisations (ECO).
ECO Spokesperson, Barry Weeber said the decision by the Acting-Minister of Fisheries to increase the New Zealand catch
of southern blue fin tuna by 27 percent goes against the urgent need for further reductions in catch of this endangered
species.
“Southern blue fin tuna is estimated to be less than 5 percent of its original stock size and declining.”
Mr Weeber said to achieve sustainable population levels in 20 years would require catches close to zero. “The Government
should have acted to put quota on ice rather than increasing the catch limit.”
Mr Weeber said the decision to not cut the catch limit for rock lobster was unfathomable and went against the claims by
the Ministry of Fisheries that New Zealand runs a cautious fisheries management decision.
The East Cape rock lobster stock needed an urgent cut to allow the population to rebuild. “The stock is in a parlous
state and is estimated to be at half the minimum sustainable level at about 10 percent of its unfished stock size.”
Mr Weeber, said the New Zealand Government has so far failed to live up to its commitment to protect endangered species
or to sustainable management of fisheries. “This comes a week after the Government opposed a decision to list Atlantic
bluefin tuna with the Convention on the Trade in Endangered Species (CITES).”

Notes:
1. ECO – the Environment and Conservation Organisations was established in 1972 and represents 67 groups with a concern
for the environment.
2. Southern bluefin tuna is listed on the IUCN Red List of endangered species as critically endangered. See: http://www.redlist.org/apps/redlist/details/21858/0 Punt, A. 1996. Thunnus maccoyii. In: IUCN 2009. IUCN Red List of Threatened Species. Version 2009.2.
3. Southern blue fin tuna is covered by the Convention on the Conservation of Southern Bluefin Tuna (CCSBT) which is
based in Canberra, Australia. Analysis over recent years identified a high level of illegal fishing by Japanese
interests and questions over Australian reporting of caged tuna production.
4. At the last meeting of CCSBT: South Africa and the European Community expressed concern at the catch limit set. They
noted that “this represented a significantly lesser reduction than was required to recover the stock status. They felt
that the agreed TAC [catch limit] would not in all likelihood lead to an overall improvement in stocks of SBT."
5. The current global catch limit for bluefin tuna is over 9000 tonnes which is over 50 percent greater than the level
required to give the stock a chance of rebuilding to 20 percent of its original size in 20 years.
6. The Gisborne or East Cape rock lobster quota are is one of nine quota areas. The Gisborne area is currently
considered the most stressed. The latest stock assessment estimates the current stock size to be half the sustainable
level of biomass that supports the maximum sustainable yield (Bmsy) stock size.
“These results suggest a stock that is near Bmin and well below Bmsy. Under current catches and recent recruitments the
model predicted a 75% probability of biomass decrease over four years.” Ministry of Fisheries, November 2009.
7. The Gisborne or East Cape catch limit or TACC would need to be reduced to around 100 tonnes to increase the chance of
the stock being above Bmsy to around 20%Bo. The current commercial catch limit is 164 tonnes.
6. The Convention on the Trade in Endangered Species is meeting in Doha, Qatar until 25 March. The convention meets
every two years to consider proposals from countries to change listings or add new species to the Convention’s
appendices. CITES has been working to protect species (both animals and plants) threatened with extinction since 1975
and now has 175 countries as members including New Zealand. The convention protect around 30,000 species globally and
has until recently been focused only on terrestrial species including birds. Atlantic bluefin tuna is listed as an
endangered species on the IUCN Red List.
