Full textTiivistelmä Uiton jälkeisten kunnostustoimenpiteiden määrä Suomessa on ollut huomattava, mutta vaikutusten arviointi, pelkästään kalastonkin kannalta, on jäänyt vähäiselle huomiolle. Tässä työssä selvitettiin kunnostusten merkitystä lohen ja taimenen poikasvaiheille, huomioiden etenkin pohjan rakenteellisen monimuotoisuuden vaikutus. Työssä selvitettiin myös kunnostusten vaikutuksia lehtikarikkeen pidätyskykyyn, joka on erityisesti latvapurojen ekosysteemien tärkeimpiä perustoimintoja. Lohikalojen talviekologinen tutkimus on viime aikoihin saakka ollut vähäistä, vaikka talviolosuhteiden uskotaan rajoittavan pohjoisten virtavesien eliöstön elinmahdollisuuksia. Kokeellisessa työssä rännimäisissä uomissa talvehtiminen aiheutti taimenenpoikasille tilapäisen painon alenemisen ja nopean kompensaatiokasvun loppukeväällä. Kompensaatiokasvu voi vaikuttaa negatiivisesti koko kalan eliniän, joten kunnostusten tuoma hyöty sopivien suojapaikkojen lisääntymisenä voi edesauttaa lohikalojen pitkäaikaista menestymistä. Kiiminkijoella lohenpoikasten tiheydet eivät muuttuneet kunnostuksen myötä ja vuosien välinen vaihtelu oli kuuden vuoden seurantajaksolla huomattavan suurta. Elinympäristömallinnuksen perusteella soveltuvan elinympäristön lisäys ei ollut merkittävää, koska etenkin talviaikaisten alueiden puute jäi huomattavaksi. Suurin osa soveltuvasta elinympäristöstä sijaitsi joen reuna-alueilla, joten kunnostusvaikutus joen keskiosaan jäi odotettua pienemmäksi. Uittoperkaus on voinut johtaa latvavesien ekosysteemien köyhtymiseen maalta tulevan orgaanisen aineksen pidättymiskyvyn vähentyessä. Kokeellisen työn perusteella kuitenkin nykypäivän tilanne vuosikymmeniä uiton loppumisen jälkeen osoittautui lähes yhtä pidättäväksi kuin nykyisin käytetyt kunnostusrakenteet (kivi tai puu). Kunnostusrakenteeseen tulisi lisätä huomattava määrä puuta, jotta lehtikarike pidättyisi korkeallakin virtaamatasolla. Tulosten perusteella elinympäristöjen muuttaminen monimuotoisemmiksi ei takaa kunnostustoimien onnistumista, sillä etenkin kalapopulaatioita rajoittavat yleensä useat tekijät. Jos kuitenkin elinympäristö on populaatiota rajoittava resurssi ja sitä pystytään lisäämään (kuten talviaikaiset suojapaikat), voidaan kunnostuksella saada näkyviä tuloksia. On ilmeistä, että kunnostustoimien tulisi olla nykyistä kattavampia ja paremmin suunnattuja rajoittaviin tekijöihin, jotta tulokset näkyisivät

The purpose of this study focused on simulating the effects of stream habitat restoration approaches for particular species by quantifying habitat suitability. First, the habitat suitability curve (HSC) for the targeted species, known as ‘Taiwan masu salmon’ (Oncorhynchus masou Formosanus) was established based on the field investigation data. With the geographic and hydrology data, the Physical Habitat Simulation System (PHABSIM) based on instream flow incremental methodology (IFIM) was operated to simulate the variations of weighted usable habitat area (WUA) under different hydrology conditions. Thus, the relationship between habitat conditions and the specie variation was discussed. The simulation divides into two parts: Field data and experimental results. This study gathered field data from seven different sections of Chi-Chia-Wan Creek in Taiwan in June, 2005. The results of these simulations showed that the Breeding Center, Wan-Shou bridge and Dam #1 perceived highest WUA at 8741.67 m2、6816.52 m2 and 5248.88 m2 respectively; followed by Da-Chia Creek station, Yeau-Shen Creek station and Tao-Shan northern Creek station. Tao-Shan western Creek station perceived the lowest WUA at 812 m2. The percentages of usable habitat area (PUA) of these simulations suggested that Wan-Shou bridge had the highest PUA at 58.74%, the Breeding Center and Dam #1 are at 47.83% and 41.87% respectively. The above results revealed strong data correlation when compared against species investigation in seven stream section in June, 2005. Moreover, this study took the results from “An Experimental Study of Single Large Woody Debris Structure on the Change of Channel Morphplpgy (Chou, 2005)”for simulation. The results indicated that PUA reduced gradually as the slope of river raised, this was because the rising slope made velocity to increase. Under different discharge conditions, the averaged PUA of low and high discharge were about 77% to 78% but the averaged PUA of medium discharge was higher than the other two conditions, which was at 85%. Due to smaller standard deviation from medium discharge condition, it presented a much more stable and reliable habitat for Oncorhynchus masou. Under different Large Woody Debris Structure (LWDS) deployments, this study discovered that the averaged PUA of the traditional spur dike and none structure configuration were about 78%. However, the averaged PUA of the none root spur dike can be improved to nearly 85% ; out of all, several association kinds can even go up to 90%. At contrast, the averaged PUA of the tree spur dike were only 73% and appeared to have the highest standard deviation, which would cause clear diversity effects of the habitat restoration in disposing the tree spur dike.
