Töö eesmärgiks oli teada saada kui palju on viimasel ajal Eestisse rajatud kalapääsusid ning
kui palju on veel plaanis rajada. Töö jaoks vajalikud andmed sain Meelis Tambetsilt, Eesti
Loodushoiu Keskusest ning Tauno Jürgensteinilt, SA Eesti Forellist. Töö tulemus täitis seatud
eesmärgid ning sain teada et alates 2009. aastast alates on 2014. aasta alguseks rajatud meie
vooluveekogudele 40 kalapääsu ning 2015. aastaks plaanitakse rajada veel 29 pääsu.
Lühikokkuvõte inglise keeles (max 1 A4 lk.):
The aim of this research was to find out how many fish passes have recently beel built in
Estonia and also how many fish passes are still planned to built. The data, which was required
for the research has received from Meelis Tambets, Eesti Loodushoiu Keskus and also from
Tauno Jürgestein, SA Eesti Forell. The results of the research fulfilled the goals. I found out,
that since 2009 to the beginning of 2014, there are built 40 fish passes to our watercourses in
Estonia and about 29 fish passes are planned to built to 2015.
The main purpose of the current bachelor’s paper was to find out about and to give an overview of the fish passes built and still under construction in Estonia. In Estonian flowing water bodies there are about 1000 dams blocking up the fishes migrating ways. According to the water law the owners of the dams are obliged to build fish passes on the living and spawning areas of salmon, brown trout, salmon trout and grayling. By the year 2013, 40 fish passes have been built all over Estonia, 22 of them are natural, as close to the nature as possible. By the year 2015, 29 more fish passes will be completed, 24 of them will be natural. It is very important to fulfill all the criteria so that the fish pass works effectively and orderly. An orderly and operating fish pass is easily detectable, easily passable, less stress creating and harmless for the fish. The most preferable way for building fish passes has been and still is to make them as close to the nature as possible. A fish pass is the more natural, the less concrete is used and which are not operated by hi- tech machinery, but by the nature itself. I was an eyewitness of the fact that a fish pass really works. In 2012 one of the first rapids- type fish pass in Estonia was opened on the Vastse- Roosa dam. On the first day a lamprey come from below the dam, crossed the fish pass with no trouble and went on upstream. Then we can say that the fish passes built in the natural way operate effectively, and people’s work has good results. So both sides are happy: the people who can see that the fish have no problem overcoming the obstacles, and the fish themselves that can follow their senses and act under the call of the wild.
