Panfuran-S藥浴對虱目魚苗活存及其成長之影響試驗 (預報)

Abstract

In Taiwan. lots of milkfish fry for culture are imported from Southeast Asia. The imported milkfish fry are not allowed to get through customs unless they have been treated with Panfuran-S bath. However, according to culturists' experiences, those treated fry do not grow well. Thus in 1976 and in 1977 this study was undertaken with the purpose to find out the effect of Panfuran-S bath on milkfish fry. The 24-hr TLm of Panfuran-S for milkfish fry is 6.4 ppm. The results also indicate that the health condition of milkfish fry seems to be related to the effect of Panfuran-S bath. 為暸解Panfuran-S藥浴對虱目魚苗活存及其成長之影響，於1976年及1977年虱目魚苗汛期，進行生物檢定及模擬進口時之藥浴試驗，而得下述之初步結果： 1.依據生物檢定試驗結果，推算24小時之TLm為6.4 ppm。 2.若按目前進口魚苗檢疫措施所採用之藥浴濃度與時間（以0.4 ppm藥浴4小時），對虱目魚苗之毒性不大，但藥浴前之魚茁健康狀況可能與藥浴後之活存及其成長有關。
