Abstract
Description
(1)供試クルマエビ
野外の養殖場から搬入した平均体重12.5gのクルマエビを水温25±1℃で1週間馴致飼育したのち、以下の試験に供した。
容量1トンのFRP角水槽4台の底面に、20cmの厚さとなるよう砂を敷いたのち、上記のエビを1水槽あたり46尾ずつ収容し、水温25℃から1日に1℃ずつ昇温し、30℃に達したのちに試験を開始した。
1区にはアルギニンを3.0%(w/w)、トリプトファン0.6%(w/w)含有する比較製剤を与え対照区とした。2区には、比較製剤に比べアルギニンを0.5%(w/w)増量(アルギニン3.5%(w/w)含有)した製剤1を、3区には比較例に比べアルギニンを1.0%(w/w)増量(アルギニン4.0%(w/w)含有)した製剤2を、また4区には比較例に比べアルギニンを2.0%(w/w)増量(アルギニン5.0%(w/w)含有)した製剤3を与えた。
アルギニン(およびトリプトファン)投与区および対照区における試験期間中の死亡尾数、生残率、残餌量、摂餌量、増体重量および脱皮状況について調べ、その効果を評価した。
(1)供試クルマエビ
野外の養殖場から搬入した平均体重14gのクルマエビを水温15±1℃で1週間馴致飼育したのち、以下の試験に供した。
容量1トンのFRP角水槽4台の底面に、20cmの厚さとなるよう砂を敷いたのち、上記のエビを1水槽あたり50尾ずつ収容し、水温15℃から1日に1℃ずつ降温し、12℃に達したのちに試験を開始した。
上記と同じく1区にはアルギニンを3.0%(w/w)含有する比較製剤を与え対照区とした。2区には、比較製剤に比べアルギニンを0.5%(w/w)増量(アルギニン含有量3.5%(w/w))した製剤1を、3区には比較製剤に比べアルギニンを1.0%(w/w)増量(アルギニン含有量4.0%(w/w))した製剤2を、また4区には比較製剤に比べアルギニンを2.0%(w/w)およびトリプトファンを1.0%(w/w)増量(アルギニン含有量5.0%(w/w)、トリプトファン含有量1.6%(w/w))した製剤3を与えた。
アルギニン(およびトリプトファン)投与区および対照区における試験期間中の死亡尾数、生残率、残餌量、摂餌量、増体重量および脱皮状況について調べ、その効果を評価した。
(1)供試魚
長崎県の種苗生産場から搬入した平均体重52gのマダイを水温25±1℃で1週間馴致飼育したのち、以下の試験に供した。
容量500リットルの円形水槽に、上記のマダイを1区あたり(すなわち、1水槽あたり)30尾ずつ収容し、水温25℃から1日に1℃ずつ昇温し、29℃に達したのちに試験を開始した。
1区にはアルギニンを2.5%(w/w)含む比較製剤を与え対照区とした。2区にはアルギニンを3.0%(w/w)含む製剤4を、3区にはアルギニンを4.0%(w/w)含む製剤5を、また4区にはアルギニンを5.0%(w/w)含む製剤6を与えた。
アルギニン投与区および対照区における試験期間中の死亡尾数、生残率、残餌量、摂餌量、増体重量について調べ、アルギニンの効果を評価した。
