英语翻译
This study investigated aspects of salinity on hatching viability and growth performance of fish
to use as a measure for aquaculture in brackish water.The experiments were carried out
under controlled laboratory conditions.The hormonal induction spawned eggs,and farm reared fry fish of
an average body weight of 1.51 - 1.54 g were used in this study.The tested media were prepared using
fresh seawater diluted with dechlorinated supplied tap water.It was found that hatching rates for the
artificially fertilized eggs were 77 - 92 % in salinities of 0 - 4.5 ppt.The LC50 (24 h) was found to be 5.1
ppt.Hatching was not observed in salinities higher than 7.5 ppt.When fry were reared in different
salinities for 40 days,they were found to grow best in salinity of 6.9 ppt.Normal growth rates were found
in salinities up to 10.2 ppt.The fry stopped growing and gradually died off in salinities higher than 12.4
ppt.This study suggests that brackish water can potentially be used for fish aquaculture.Saline
water up to 4 ppt is practical for propagation of the fish.The fry may be nurtured in
brackish water of 6 - 7 ppt to obtain the best growth performance.
The average difference in mass of the fishes subjected to brackish water is 2.945 grams higher than freshwater and the average difference in length is also higher than fresh water by 1.265 cm.
Brackish water is the best water treatment for the growth of fish.

人工翻译,请放心采纳.本研究调查了盐度对鱼的孵化活力和生长性能的各个方面,以用作微咸水中水产养殖的一个量度.实验受控的实验室条件下进行.本研究中采用了激素诱导产卵的鸡蛋,以及平均体重为1.51～1.54克的农场饲养的鱼苗.使用以脱氯的自来水稀释了的新鲜海水制备了试验介质.人们发现,对于人工受精的鸡蛋来说,孵化率在盐度为0～4.5ppt情况下为77 - 92％.LC50 （ 24小时）被发现是5.1ppt .在盐度高于7.5ppt的情况下没有观察到孵化.当鱼苗饲养在不同的盐度下40天时,发现它们在6.9ppt的盐度下生长得最好.发现正常的生长速率是在10.2ppt以下.在高于12.4ppt的盐度下鱼苗停止生长并逐渐死去..本研究表明,微咸水可以潜在地用于鱼的养殖.最高为4ppt的盐水对于鱼的培养繁殖是切实可行的.鱼苗可以在6～7ppt的微咸水中培养,以获得最佳的生长性能.
经受微咸水的鱼的质量（重量）平均差别比经受淡水的高2.945克,而长度的平均差别也高于淡水1.265cm.微咸水是用于鱼生长的最好水处理措施.
