After a severe decline
in the vendace stocks at the beginning of the 1990s there is
now a general phase of recovery in the vendace stocks. Increased
catches and a steady demand have made vendace fishing profitable,
especially in the central lakes of the larger water systems.
The better conditions are also due to the improved state of the
environment, manifesting as cleaner water in Lake Päijänne,
for example.
Vendace trawling was
introduced in Lake Päijänne at the beginning of the
1980s, and after a few years the number of trawling gangs was
five. The following decade doubled the number. As a result of
good catches, trawls replaced seines as the major gear among
the commercial fishermen. In some areas this new method restored
fishing once more as a source of livelihood after a pause of
several decades. Vendace dominated as target species at first,
but since the beginning of 1990s the share of whitefish in the
total sales has increased, with perch and roach also contributing
to the good results. It has been confirmed that effective trawling
has increased the growth of natural stocks of migrating whitefish
in Lake Päijänne.
Trawling on a lake
differs little from trawling at sea, only the vessels are smaller
and less effective. The gear is light and the latest technology
is used where possible. The economical use of energy in trawling
on the lakes in Finland is among the record achievements in the
world. The objective of the operation is to guarantee the best
possible quality and producer price by making short fishing trips
and prompt deliveries of fresh fish to the consumers in the nearby
communities. The operation costs of the vessels and gear have
to be in a correct proportion to the catches. In summer the importance
of an unbroken cold chain is emphasized.
The natural conditions
on a lake do not effect fishing as much as they do at sea. The
fishing season lasts as long as the waters are open. Fishing
is carried on through the night and sometimes fish are caught,
sometimes not. In many places the uninterrupted sound of a diesel
motor carried from the lake has become part of the atmosphere
in summer evenings.
