Growth Characteristics of Rhopilema esculenta and its Relationship with Surface Water Temperature During Rapid Growth Period in Hangzhou Bay
摘要
Abstract
In order to investigate the relationship between the growth characteristics of Rhopile-ma esculenta and surface water temperature during the rapid growth period in Hangzhou Bay,the authors conducted a survey of Rhopilema esculenta biology and environmental factors in Hangzhou Bay in June-July 2022.The results showed that:(1)The umbrella diameter of Rho-pilema esculenta ranged from 45 to 650 mm,the average umbrella diameter was 327.55 mm;the body mass of Rhopilema esculenta ranged from 9 to 18 260 g,the average body mass was 2 748.21 g.(2)The relationship between umbrella diameter and body mass was given by W=1.578 5×10-5 UB3.120 8(R2=0.975 4,n=1 601).(3)With the increase of date,the average um-brella diameter of Rhopilema esculenta increased from 104.33 mm to 361.20 mm and the average surface water temperature increased significantly from 21.69 ℃ to 27.94 ℃.(4)The average umbrella diameter and average surface temperature during the investigation period were fitted,and the relationship between them was as follows UB=6.07ST2-259.62ST+2 880.32(R2=0.998 5).(5)After the opening of the fishery,the umbrella diameter of Rhopilema esculenta ranged from 115 to 650 mm with an average umbrella diameter of 391.96 mm;the body mass ranged from 40 to 18 260 g with an average body mass of 3857.60 g.The umbrella diameter and body mass of Rhopilema esculenta gradually increased with the date.This article studied the growth characteristics of Rhopilema esculenta and its relationship with surface water tempera-ture during the rapid growth period in Hangzhou Bay,which can provide a reference basis for scientific mangement of Rhopilema esculenta fishing production during the summer fishing mor-atorium in Hangzhou Bay in the future.关键词
