Abstract:

Biofouling on marine installations is a major factor of increasing operation cost and affecting their safety and ser- vice life. Acorn barnacle Balanus reticulatus, green algae Enteromorpha linza and Ulva lactuca, and red alga Gracilaria tenuistipitata are common fouling species in the coastal waters of southern China. This paper deals with the method for the collection and culture of their larvae and spores. Nauplii of acorn barnacle B. reticulatus was reared in darkness at 30℃ for 5 days, and then metamorphosed to cyprids that could be stored at 4℃. A large number of zoospores released when green algae E. linza and U. lactuca were irradiated at the light intensity of 4000lx. Concerning the red alga G. tenuistipitata, carpospore release was induced after the thalli was treated by shade drying first and then immersed in seawater. The spore germination of the green algae E. linza and U. lactuca was observed after being incubated at a room temperature (21?26℃) with 900?1300lx light intensity on a 12h light and 12h darkness cycle for four days, and red alga G. tenuistipitata was at 18?23℃ for two days.
