摘要

The sound stimulus has a signifi cant impact on marine animals.However,many studies have focused on the negative impacts of sound on marine vertebrates.The positive impacts of sound on marine animals,especially on marine invertebrates,were rarely studied.In the present study,we evaluated the eff ects of music on the survival and development of an economically important marine invertebrate,swimming crab Portunus trituberculatus.Three pieces of classical music and a control group,i.e.,Eine Kleine Nachtmusik by Mozart(EK),Bach-Violin Concerto No.1(BV),Anonymous Romanza by Anonymous(AR),and environmental sound(EN)were used.The sound pressure received were 163-dB root mean square(RMS)re 1μPa for EK,166-dB RMS re 1μPa for BV,165-dB RMS re 1μPa for AR,44-dB RMS re 1μPa for EN,respectively.The larvae were subject to 3-h classical music transmission every day during the entire larval development period.The result showed that BV and AR signifi cantly elevated the cumulative survival rate of the larva from 3.42%±1.77%(EN)to 10.65%±1.69%(BV)and 7.12%±1.37%(AR)respectively(P<0.05).Though music did not aff ect the cumulative development time of larvae from ZoeaⅠto ZoeaⅣ,it signifi cantly increased the molting rate of megalopa from 24.00%±11.78%(EN)to 44.00%±13.06%(AR)and 46.67%±10.50%(BV)(P<0.05).Musical exposure during critical growth intervals may contribute to the survival and development of larval crustaceans.From an application point of view,music intervention is much economically feasible.The observed music eff ects imply that music could further enhance growth,welfare,and production.
