| 内容記述 | After releasing H. discus hannai reared for 2-years into an Eisenia bicyclis marine afforestation area, a high primary production area and a sea-desert area in Matsushima bay, a study was conducted on the growth of the abalones, and on the standing stock of the dominant herbivorous animals and marine benthic algae for 2 years in each area. The growth rates of the abalones, 18. 9+7.1, 23.5+6.3 and 6.8+1.1 mm/yr respectively, being bound to the primary production in each area, their survival rates were approximately equal beyond the differences among the areas. The survival rate (80%/yr) was much higher than that reported before (<30%/yr) on small size individuals (<30 mm). It was showed that the population density of herbivorous animals other than abalone was higher outside the colony of large type algae, especially in the sea-desert area. The colony of E. bicyclis decreased with the release of the abalones. The atrophy could be due to the feeding pressure of the abalones and the other herbivorous animals which swarmed around the area where the density of E. bicyclis had been made lowered by the abalone. | |||||
