Description
更に、淡水性寄生虫に対する海水浴療法の場合にも、濃度の管理が困難であると共に、塩分の混入した廃液が処理されずにそのまま河川などの自然界へ廃棄される恐れあるため、自然界に悪影響を与えて環境汚染の原因となるという問題がある。
また、海水性寄生虫に対する淡水浴療法の場合には、淡水性寄生虫が寄生する淡水魚に対しては有効ではなく、全ての養殖魚や観賞魚に採用できないという問題がある。
その他にも、オゾン殺菌や銅イオンによる駆除方法もあるが、これらの場合には新たに装置を設置する必要があってコストアップになると共に、銅イオン濃度を制御することが極めて難しいなどの問題がある。
従って、海水性及び淡水性の寄生虫病に対して、安全且つ簡便、汎用な治療方法や予防方法が未だ確立されていないのが現状である。
特に、サケは、その稚魚の状態で放流しているが、その放流魚のうち90%以上は何らかの原因で死亡しており、サケの回帰率を向上させるためにも放流前に放流魚の寄生虫検査を行い必要に応じて駆除するだけでなく、稚魚の耐力調査を行う必要がある。
しかし、現状では塩水を使用する方法以外に魚体の耐力を試験する方法が確立されていない。
また一つには、魚体耐力試験方法として、水槽に寄生虫の感染魚を含む魚を入れ、該水槽の水温を初期温度から設定温度まで上昇させ、前記魚の生存率を調査する予備実験を行う工程と、前記予備実験で体力の弱い魚の生存率が低いことが確認された前記設定温度を求める工程と、前記予備実験の対象とした感染魚を含む魚の飼養環境の水温を前記設定温度まで上昇させる工程とを有することを特徴とする。
一方、一定量以上の寄生虫が寄生した感染魚は、これら寄生虫による過剰な刺激に対し、本能的に川底の低温水と川面の高温水とに亘って移動することにより、これらの温度差を利用して、その魚体外部に付いた寄生虫を払い落とすと共にその生存数を減らしているのでないかと仮定し、この仮定を立証するために後述する寄生虫駆除装置を使って実験を行った。
以下、本発明の各実施例を図面に基づいて説明する。
先ず、飼育水槽や養魚池から水と感染魚Aを同時に採取し、各感染魚Aの魚体外部に寄生した寄生虫の寄生数を顕微鏡などで計測してから水槽1に入れ、その後、前記ヒーター2及びコントローラー3により、水槽1内の水温を上述した図2の温度グラフのように上昇させるが、その高温領域H2に到達する前の昇温途中で、水槽1から感染魚Aを取り出して寄生虫の状態を顕微鏡などで確認する実験を行った。

3 コントローラー H1 初期水温
H2 高温領域
