Comparison of growth characteristics of Paphia textile in middle culture and adult periods in Beibu Gulf of Guangxi
摘要
Abstract
[Objective]This study aimed to investigate the suitable culture density and growth patterns of Paphia tex-tile during the middle culture and adult periods in the Beibu Gulf sea area of Guangxi,providing data reference for scale and efficient culture of P..textile in this region.[Method]From January 2022 to July 2023,middle culture,adult culture,and cage-hanging culture experiments were conducted in the intertidal zones of Shachongping,Yingpan,Beihai sea area,Zhenzhuwan,Bailong Fangchenggang sea area,Fishing port,Xiniujiao,Qinzhou sea area.Growth performance of P.textile at different sea areas and densities was compared.The shell length-body mass allometric growth equations were es-tablished using power function regression analysis.[Result]The suitable middle culture densities for P.textile in Shachong-ping,Yingpan,Beihai sea area,Zhenzhuwan,Bailong Fangchenggang sea area,Fishing port,Xiniujiao,Qinzhou sea area were 2000,2000 and 1000 grain/basket,respectively.P.textile in Shachongping,Yingpan,Beihai sea area showed better growth performance and survival rate than the other two locations,and showed a decreasing trend with in-creasing culture density.During the adult period,the suitable densities were 60,50,and 40 grain/basket in the above three sea areas,respectively,with growth indexes and survival rates ranking as Shachongping,Yingpan,Beihai sea area＞Zhenzhuwan,Bailong Fangchenggang sea area＞Fishing port,Xiniujiao,Qinzhou sea area.In the cage-hanging culture experiment in Zhenzhuwan,Bailong Fangchenggang sea area,the growth indexes and survival rate decreased with in-creasing density,the appropriate cage-hanging density was no more than 50 grain/cage.During the middle culture period,the growth relationship between shell length and body mass of 3-month-old P.textile showed positive allometric growth(rapid growth).However,9-month-old P.textile during the adult culture period and 18-month-old P.textile during cage-hanging culture period showed negative allometric growth(slow growth).[Conclusion]Basket bottom sowing mode in the intertidal zone in Beibu Gulf of Guangxi is feasible for middle culture and adult culture of P.textile.Shachongping,Yingpan,Beihai sea area is the optimal location among three sea areas,with suitable density of 2000 grain/basket for middle culture,and 60 grain/basket for adult culture.Cage-hanging culture in Zhenzhuwan,Bailong Fangchenggang sea area is suitable for 15-month-old P.textile,which can mitigate the negative impacts of predation and high summer tem-peratures experienced in bottom sowing culture.关键词
