UK’s Waitrose refuses to stock NZ-caught hoki

Posted by feww on July 21, 2009

British supermarket chain Waitrose confirmed it refuses to stock New Zealand-caught hoki

Waitrose, a large British supermarket chain, confirmed that it is refusing to stock New Zealand-caught hoki because bottom trawling is used in New Zealand fisheries.

Fishing for hoki – The deep-sea fish hoki, also known as blue hake or blue grenadier, is one of New Zealand’s biggest fish exports. Hoki fishing began in the Tasman Sea, but has expanded to include Cook Strait, the Chatham Rise and subantarctic waters. In the decade to 2002 the annual quota for the catch was 200,000 tonnes. In 2004 the Tasman Sea stock was estimated to be down to about 13% of the biomass before fishing developed in 1972, with a warming trend in the Tasman likely to be a contributing factor. The quota was reduced to 180,000, then to 100,000 tonnes in 2004. Caption: NZ govt.

“There are some MSC fisheries that we don’t stock, such as the MSC New Zealand hoki fishery, which conducts bottom trawling,” Jeremy Langley, specialist fish buyer for Waitrose said in a report by

At least a dozen other supermarket chains in Europe and North America have also removed New Zealand caught orange roughy from their shelves because it goes against their sustainability policies. “Orange roughy is also caught by bottom trawling, dragging large, weighted nets across the ocean floor which lays waste to seabed communities, particularly on the seamounts where some fish species gather to feed and reproduce, and is considered one of the most destructive forms of fishing.” A report said.

“Waitrose has also pledged to buy only pole-and-line caught canned tuna.” Seafood News said.

Orange Roughy can live for around 150 years and do not begin to breed until they are around 25 years old, making them extremely susceptible to over-fishing. Image courtesy of R.

The time has come for ALL supermarket chains to consider refusing to stock New Zealand meat products, too!

Powerful 7.8 M Quake Strikes New Zealand Region

Posted by feww on July 15, 2009

Magnitude 7.8 M Earthquake Strikes Off West Coast of South Island, New Zealand

A powerful earthquake measuring magnitude 7.8 occurred off west coast of South Island, New Zealand, about 150 km  WNW of Invercargill, at 09:22:32 UTC, USGS reported.

The mainshock, which occurred at a depth of 35 km, was followed by a large aftershock measuring 5.8 Mw some 20 km WSW of the mainshock about 20 minutes later. [Location, 45.991°S, 166.238°E; depth, 35km; event ID, us2009jcat/USGS]

The aftershock was reported as measuring 6.1 on Richter scale, and at a depth of 5km, by New Zealand’s GNS Science Earthquake Information.

FEWW EarthModel simulations suggest the latest earthquakes may well be a prelude to an extended period of intense, likely catastrophic, seismic and volcanic activities in the New Zealand region. Lots of ‘fireworks’ may follow.  [See links below for forecasts and travel advisories.]

On May 9, 2009, FEWW Moderators issued the following warning to tourists planning to visit New Zealand:

A Warning to Visitors to New Zealand:

Climatological and Geological Warning! The New Zealand region is about to experience significant climatological events and large-scale geological and tectonic activity over an extensive period of time. Would be visitors are advised to stay out of the area for the foreseeable future.

What the local experts said

It’s interesting and quite comforting [sic] to note, as our colleague TERRES pointed out earlier, the local experts had assured New Zealanders “there was no cause for worry,”  and that the frequent quakes earlier this year were not “leading up to the ‘big one.'”

Magnitude 7 Earthquake Hits Kermadec Islands

Implication for New Zealand Islands:

  • A substantial increase in the frequency of earthquake striking the twin islands.
  • More earthquakes with magnitude 6 or larger.
  • A marked increased in large explosive volcanic eruptions, especially in the following zones [also includes ‘extinct’ volcanoes]
    • Taupo Volcanic Zone
    • Bombay Hills
    • Auckland volcanic field
    • Mount Taranaki
    • Mt Horrible volcano
    • Mount Taranaki
    • Mount Cargill

Worst Case Condition for New Zealand Islands:

Will a magnitude 9.8 (MW) earthquake centered at 42° 00′ 59″ South, 175° 05′ 07″ East herald the end of New Zealand Islands?

  • Large earthquakes and massive volcanic eruptions could potentially destroy much of New Zealand structures and claim many lives.
  • Earthquake and volcano-triggered waves could also give rise to 40 to 50-meter tsunami that would engulf the coastal areas and low-lying lands throughout New Zealand [could also affect parts of Australia’s eastern seaboard,] compounding the damage.
  • A super/mega colossal Plinian/Ultra-Plinian eruption occurring in New Zealand’s North Island simultaneously [or within a short period of time] with a magnitude 9.8 earthquake off the eastern coast of New Zealand could claim many lives.
  • Probability of occurrence:
    1. Event 1.  A magnitude 9.8 earthquake striking off the eastern coast of New Zealand with (i) the foreshocks ripping through Auckland, Hamilton, Taupo areas, (ii) the mainshock leveling Wellington, Palmerstone North, Marlborough, Nelson and Christchurch, and (iii) the aftershock causing substantial damage as far south as Invercargill: 85%
    2. Event 2. A super/ mega colossal Plinian/Ultra-Plinian eruption in the North Island: 72%  [South Island: 57%]
    3. Event 1 and Event 2 occurring simultaneously, or within a short period of time: 64 %
