盐度对宽壳全海笋稚贝存活与生长的影响
Effects of salinity on the growth and survival of Barnea dilatata juveniles
摘要
Abstract
Hatchery-reared Barnea dilatata juveniles were maintained under different salinity levels of 15,20,25,30,35 and 40 psu at 20±1 ℃ to study the effects of salinity on the survival and growth.The results showed that the survival rate was over 90.0％ under salinity of 20,25,and 30 psu after 28 days,which was significantly higher than that observed under salinity of 15,35,and 40 psu.The bivalves exhibited the highest increase of wet weight under the salinity of 20 and 35 psu,with the specific growth rate (SGR) at 2.963％ · d-1 and 3.028％ 1 d-1,respectively.The shell length and height showed similar changes in SGR between 25 and 35 psu.The highest ratio of organic and inorganic materials (OIR) was detected in the edible part of juveniles cultured under the salinity of 30 psu (OIR 4.396).The bivalves grown under 25 psu salinity had the second highest OIR at 3.375.Collectively,data from this study provide valuable information for the selection of suitable sites for B.dilatata aquaculture and for maintaining optimal rearing conditions at the B.dilatata hatcheries.关键词
