Abstract
The following experiments were carried out at rock method oyster field at Uduri, Dolsan-myon, Yeocheon-gun, Jeon-nam, Korea, in 1966. In this experiment, the settling rate of oyster at each exposure level and their growth rate were checked. 1. The settling rate of oyster spats was highest at 4 hour exposure level in the day-time during spring tide, and the growth rate became greater the lower stratum until 3 hours and 30 minutes exposure level. 2. Rocks applied at the place higher than 5 to 6 hour exposure level which amount 26 percents of applied rocks, were not utilized properly because the settling rate of spats and their growth rate were very bad. 3. For the future application of rocks for oyster culture, effort should be paid to instruct the oyster farmers to apply all rocks at proper exposure Ie el with bottom leveling and the rocks should be spaced properly for better barvest.
1. 1966년 9월에 여설한 전남 여천군 돌산면 우두리 투석식 굴 양식장에서 각 노출선에 따른 부착률과 성숙도를 조사하고 투석결과에 대한 결과를 조사했다. 2. 표준노출선 산출법에 의한 대호일의 서간 반일 호석에서 4시간 노출선이 가장 부착율이 좋았으며 성장도는 3시간 30분 노출선까지 사이에 있어서는 깊어갈수록 좋았다. 3. 부착률과 성장도로 봐서
