Steinar Bjørnstad, lives in a small valley near Geilo in
Norway and regularly visits New Zealand to fish for big trout. He
has made seven trips over the past 26 months. In this article he
explores an intriguing connection between his country and New Zealand
and shows how Norway has contributed to the great fishing that we
in New Zealand experience today.

| The beginnings of the quest |
Ever since 1985 when I celebrated
my fortieth birthday by fishing for a week during the wonderful month
of May on the famous rivers Test and Itchen in England's Hampshire,
I have become curious about where the ice came from that made the
successful voyage of trout ova possible to Melbourne and Tasmania
and finally on to New Zealand. |
| The Nordic connection |
The first Scandinavians arrived in New Zealand
on September 13, 1872 arriving in Napier. Their sailing ship Høvding
of Tønsberg carried 413 adults and children. Most were Norwegians.
The voyage lasted 114 days. |
| The first experiments |
Some years previously James
Arndell Youl (1811-1904), an Australian pastoralist, did a lot of
research in an effort to safely transport trout eggs to the southern
regions. In February 1860 the Sarah Curlng sailed from an English
harbour with 30.000 eggs packed in pine boxes. Under deck was an
ice compartment with two adjacent rooms covered with graphite. The
space between the rooms was filled up with charcoal dust. A full
water tank above the icehouse with a hose into the tanks contained
sufficient water to keep the eggs alive.
But this effort failed after 15 tonnes of ice
melted. On the 68th day of the voyage the last eggs died. A further
attempt two years later aboard Beautiful Star similarly ended in
failure.
Youl was up against the obvious obstacles of
a long voyage, weather conditions, and the necessity to sail through
tropical regions. But he was a man not easily deterred from a mission.

| A New Experiment |
January 21, 1864 heralded
another attempt by Youl, aboard the Norfolk carrying a gift of trout
eggs from Frank Buckland, and Francis Francis who was editor of
the magazine The Field – Francis arrived in Melbourne,
Australia, on 15 April 1864. Trout eggs from the rivers Itchen,
Whycombe and Wey, were involved in the Norfolk experiment. They
were packed in boxes of inch-thick pine. The boxes measured 12x8x5
inches, with top and bottom sides perforated. At the bottom was
a layer of fine charcoal covered with a layer of ice and on top
of that a nest of washed moss.
On this springy bed of moss the eggs were placed.
Over the eggs was another layer of moss and on top of that, a layer
of crushed ice. The whole thing was in a trough perforated with
water vents and locked with screws. One hundred and eighty nine
such boxes containing 100,000 salmon eggs and 3000 trout eggs were
packed in the icehouse and on the top were three meters of ice in
large blocks
|
| Success at last |
The Australian State of Victoria
received 4000 salmon eggs. Of them 400 had hatched. The remaining
eggs were sent to Tasmania onboard a government steam ship. The
ova was shipped to the Derwent River (to New Norfolk) and placed
in a well prepared hatchery. An estimated 30,000 salmon eggs and
500 trout eggs were still living.
On May 4 the first ova hatched to become trout
fry and by May 25, 300 trout and 700 salmon eggs had transformed
into fry. At the end of 1865 the surviving salmon were transferred
to the ocean. Youl had achieved something others had for a long
time suggested. He was later honored with a knighthood in Australia
and a silver cup from New Zealand. Curiously, his achievement was
recognized in France when, in 1866, he was awarded a gold medal
from La Société d’Aclimatisation
Several more successful attempts at transporting ova to Australia
were made from 1865 until 1870. Francis and Buckland shipped ova
from the same rivers in Hampshire. All of them were introduced via
Tasmania.
As connections with shipping agents were established
ova was also sent to New Zealand from 1867. After a short time good
results were experienced with the successful; liberatiion of trout
into the rivers south of Christchurch and Otago. |
| The Ice – From where? |
This has long been a curiosity
for me. It is clear that England did not produce any ice from 1860
to 1880. The coldest month was in January 1862 with minus 0.5 for
just a few days according to Norwegian meteorologists.
Gothe Gothes author of With Ice and logs cross
the North Sea presents a great documentary for this transportation.
From Norway, sailing ships went to most of the countries in Europe
to keep the ice solid. The ice was taken from Oslofjord and from
lakes down the coast from Oslo.
Ice for export was also taken from the Folgefonna
Glacier. Initially Norway did not trade ice with Britain because
of high cost. But a limited ice export became a reality with the
developing British food industry and continued until technology
(after the turn of the century) enabled artificial ice production.
Norway’s early ice export to all countries was around 400-500
000 tonnes annually. The ice blocks were large – 0.3m cubed.
Extracting them was a dangerous operation. Men died and ships were
crushed in the cold sea.
Norwegian ice from the Oslofjord region and down
the coasts (as far as Drøbak on the east and Kragerø
on the west) was necessary for those pioneer Southern Hemisphere
shipments until Tasmania and New Zealand became self-reliant in
ova. |
| Years 1880 to 1921 |
In this period, 28 hatcheries were established
throughout New Zealand, which produced 64 million fry. These hatcheries
were fundament for the excellent organizing of the trout fisheries
in New Zealand these days. Many fishermen around the world have asked
themselves: ``Why do trout grow so big in New Zealand?’’
It is all about food, and catch and release. I am presently at my
home in Geilo Norway. Outside it is minus 16 deg. Celsius and lots
of snow. In my mind I relive my seven journeys to New Zealand’s
wonderful rivers and lakes. |
| Visiting New Zealand’s South Island |
The first time I visited
New Zealand was in January 1998. On the very important first cast
in a nice late evening, almost under the bank on the other side
of the Ahuriri river, a 2 kg brown eating a late supper made a mistake.
The menu included an artificial fly. A caddis fly No 14 did the
job. After releasing the trout I felt such a great satisfaction
and I decided to return every year if I could. It was, however,
more than two years before my second visit and you can imagine how
my life has changed, lost into a new dimension of the fly-fishing
sport, thanks to New Zealand.
But these beautiful waters need to be taken care
of. New Zealand has an enviable reputation as a great fly fishing
country with big trout. I am sure, far into the future, farmers
and fishermen will work together for the ongoing good of the environment
and waterways. It gives us a very good feeling when we look at the
100 per cent Pure New Zealand commercials.
It is such a beautiful country: But it has to
be kept up to 100 per cent. That must be the vision. To run a big
station or even a smaller farm is always a challenge. Mother Earth
deserves to be taken care of. Please work hard to keep the waterways
in pristine condition – seek advice if you need to. Didymo
is a bad case of waterway pollution. Fishermen have brought it from
somewhere. That is devastating. I plead for a better understanding
so we care more, and can enjoy the outdoors with our rods and flies
for a long, long, time.
