Balanus reticulatus is a macrofouling organism that is widespread in the sea areas of Chi-na and lots of sea areas in the world.Herein,the effects of surrounding factors on the settlement of Bala-nus reticulatus cyprids on the TC4 Ti-alloy and the glass which are highly biocompatible were investigat-ed via observations of the settlement of Balanus reticulatus cyprids.The results showed that the settle-ment 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％,respec-tively.The highest settlement ratio 73.3％on the overall surface of TC4 Ti-alloy and glass was in the sea-water of 25‰ salinity,whereas the highest settlement ratio 6.67％on the TC4 Ti-alloy in seawaters of sa-linity 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.
