宽尾青鳉是一种小型的广盐性淡水鱼类，分布于盐度差异很大的环境中。根据过去的报告，Oryzias latipesspermatozoa在盐水条件下不活跃。我们确定了一个微咸水殖民人口的青鳉，在海水中表现出高受精率，并调查这是否是遗传基础。将两个G1群体在孵化后不久分别置于淡水和50%海水中。成熟后，从解剖的睾丸中获得精子，并在新鲜或海水中评价精子的活力。淡水饲养的鱼的精子仅在淡水中被激活，而50%海水饲养的鱼的精子在淡水和海水中都能活动。淡水养殖鱼类经50%海水驯化后，精子在海水中能被激活。这些结果表明，青鳉精子活力与盐度是一个表型可塑性性状。
MedakaOryzias latipesis a tiny euryhaline fresh water fish distributed in environments differing widely in salinity. According to past reports,Oryzias latipesspermatozoa are not active in saline conditions. We identified a brackish water–colonized population of medaka that showed a high fertilization rate in seawater and investigated whether this was genetically based. Two G1populations were produced and placed in either fresh water or 50% seawater soon after hatching. After maturation, sperm was obtained from dissected testis, and motility of the spermatozoa was evaluated in fresh or seawater. Spermatozoa of the fresh water–reared fish were activated only in fresh water, whereas those of the 50% seawater–reared fish were motile in both fresh and seawater. After fresh water–reared fish were acclimated to 50% seawater, spermatozoa could be activated in seawater. These results indicated that spermatozoon motility with respect to salinity is a phenotypic plastic trait in medaka.
