초록/요약 도움말
In the study, I investigated to acclimate and adapt in sea water of freshwater rainbow trout, Oncorhynchus mykiss. Used rainbow trouts were small group of 25.3~75 g and large group of 360 g, mean. Mortality tendencies showed to die after sea water acclimation, and survived almost on feminal triploid trout group out of small trout group. Also in small group, sex ratio of dead trout was 1: 1 (male: female), but the ratio was far higher in male than that of female (3: 29, female: male) in large group, because maybe a spawning season. And Na+/K+-ATPase activities during sea water acclimation periods were active in improving faster than diploid group on activities in brain and gill. Also in the activities, that of brain was active in improving faster than that of gill. Oil droplet in liver tissue of three ploid-types was increased in sea water adaptation periods than acclimation periods in three ploid-types. But oil droplet ratio on acclimation periods and RNA/DNA ratio after adaptation periods were higher in feminal triploid trout that of than others. But we could not confirm chloride cell in gill and cortisol content in blood plasm out of three ploid type trout. Therefore, we could be confirmed the best a ploid type (triploid) of trout for mari-culture, as sea water acclimation and adaptation. Also feminal triploid trout was the best for mari-culture.
