The feasibility of congealing stonematerials used as artificial reef --the species com position and biomass of organism s attached to the tested modules
Abstract: Four kinds ofmodules prepared by congealing stone material at a water cement ratio of 0.60,0.55, 0.49,and 0.44 were displaced in the same area for150 days and the species composition and biomass of organisms attached to surface of the tested modulesweremonitored in a 30 day interval.The results showed that:1)No organismswere found to be attached to the tested modules on the 30th day.The same species(about10 species)of the organisms attached to the surface of the tested moduleswere observed on the 60th day,90th day,and 120th day. On the150th day,therewere 13 species on the surface of the two testedmodules,including seaweedUlvapertusa, sea cucumberApostichopusjaponicus,sea urchinStrongylocentrotusintermedius,and clamPatelloidapygmaea.2) On the 60th day and 90th day,there were lower biomass attached to the congealing stone tested modules than on the cement tested modules,even though on the 90th day.The biomass showed more rapid increase on the congealing stone testedmodules than those on the cement testedmodules.On the 120th day,however,the biomass on the congealing stone tested modules had more than on the cement tested modules,averaging 344.85 g/cm2on the congealing stone tested modules,significantly higher than that on the cement group(260.15 g/cm2)on the 150th days.3)On the 150th day,therewere biomass of58.63,79.32,89.66,117.25 g/cm2on the four kinds ofwater cement ratio in the congealing stone tested modules,indicating that in the experiment the biomass attached to the tested module surfaceswas increased with the decrease in water cement ratio.These findings suggested that the congealing stonematerial as artificial reefs in biological attachment had the superiority to the cement reefs.
