摘要
网纹藤壶是广泛分布在中国各海域及世界许多海域的大型污损生物。通过藤壶培养及附着观察探索了不同海水环境因素对网纹藤壶金星幼虫在生物相容性极佳的钛合金表面和玻璃表面附着的影响,结果表明p H为8时金星幼虫在TC4钛合金表面的附着率及在TC4钛合金表面和玻璃表面的整体附着率达到最大值,分别为10%和76.7%;盐度为25‰时,整体附着率达最大值73.3%,盐度在(13~18)‰之间,TC4钛合金表面附着率达最大值6.67%;温度和海水流速对网纹藤壶金星幼虫附着的影响也极为显著,当温度为10℃时不附着,当温度为25℃时,整体附着率达50%,TC4钛合金表面附着率达10%;当海水流速为0时,金星幼虫附着率最高,流速达12 m/s时,金星幼虫在钛合金表面和玻璃表面均无法附着。上述环境因素对网纹藤壶金星幼虫附着的影响,可为海洋防污损策略提供依据。
Balanus reticulatus is a macrofouling organism that is widespread in the sea areas of China and lots of sea areas in the world.Herein,the effects of surrounding factors on the settlement of Balanus reticulatus cyprids on the TC4 Ti-alloy and the glass which are highly biocompatible were investigated via observations of the settlement of Balanus reticulatus cyprids.The results showed that the settlement ratio on the TC4 Ti-alloy surface and the settlement ratio on the overall surface of TC4 Ti-alloy and glass reached the maxima when pH was 8 for the artificial seawater,which were 10%and 76.7%,respectively.The highest settlement ratio 73.3%on the overall surface of TC4 Ti-alloy and glass was in the seawater of 25‰salinity,whereas the highest settlement ratio 6.67%on the TC4 Ti-alloy in seawaters of salinity between 13‰to 18‰.The temperature and the flow velocity of the seawater also influenced the cyprid settlement significantly.At 10℃,the cyprids did not settle.However,the settlement ratio on the TC4 Ti-alloy and the settlement ratio on the overall surface of TC4 Ti-alloy and glass were 10%and 50%at 25℃,respectively.The corresponding two settlement ratios all reached the highest values in the still seawater.The cyprids did not settle when the seawater flow velocity was 12 m/s.These results threw a light on the anti-biofouling for marine facilities.
