본 연구에서는 도루묵의 어업생산력 증가에 영향을 미치는 효율적인 종묘를 생산하기 위해서 도루묵의 치어기 동안에 에너지수지와 동화효율, 총성장효율, 순성장효율의 생태효율을 추정하였다. 에너지수지는 자연 해수의 갓 부화한 Artemia nauplii 실험구에서 100C=66.49G+21.28M+10.78F+1.44U, 영양강화한 Artemia nauplii 실험구에서 100C=67.54G+21.40M+9.39F+1.67U, 가온해수의 갓 부화한 Artemia nauplii 실험구에서 100C=66.86G+22.66M+8.01F+2.47U, 영양강화한 Artemia nauplii 실험구에서 100C=67.06G+22.96M+7.70F+2.28U로 나타났다. 생태효율의 동화효율, 총성장효율, 순성장효율은 자연수온에서 갓 부화한 Artemia nauplii 실험구에서 각각 87.78%, 66.49%, 75.75%로 나타났고, 영양강화한 Artemia nauplii 실험구에서 각각 88.94%, 67.54%, 75.94%로 나타났다. 가온해수(13±0.5℃)에서의 동화효율, 총성장효율, 순성장효율은 갓 부화한 Artemia nauplii 실험구에서 각각 89.52%, 66.86%, 74.68%로 나타났고, 영양강화한 Artemia nauplii 실험구에서 각각 90.02%, 67.06%, 74.49%로 나타났다. 따라서, 도루묵 치어의 성장을 촉진시키기 위해서는 가온해수에서 영양강화한 Artemia nauplii를 급이하는 것이 효과적이고, 종묘생산에 있어서는 에너지효율이 가장 높게 나타난 자연해수에서 영양강화한 Artemia nauplii를 급이하는 것이 효과적으로 생각된다.
In this study, energy budget was estimated to produce an efficient artificial seed. And it needs to enhance fisheries productivity of sandfish, A. japonicus. In order to estimate energy budget of the sandfish, A. japonicus Juvenile fed on nonriched Artemia nauplii (NA) and the enriched Artemia nauplii (EA), of sandfish were reared at constant condition of seawater temperature of natural temperature (NT) and heated temperature (HT). During the reared period, energy used by the reared juveniles were calculated from estimates of data on ingestion, growth, oxygen consumption, nitrogen excretion and energy content. Energy budget of NT-NA, NT-EA, HT-NA and HT-EA were represented as 100C=66.49G+21.28M+0.78F+1.44U, 100C=67.54G+21.40M+9.39F+1.67U, 100C=66.86G+22.66M+8.01F+2.47U and 100C=67.06G+22.96M+7.70F+2.28U. The assimilation efficiency estimated NT-NA, NT-EA, HT-NA and HT-EA were represented as 87.78%, 88.94%, 89.52% and 90.02%. Gross growth efficiency estimated NT-NA, NT-EA, HT-NA and HT-EA were represented as 66.49%, 67.54%, 66.86% and 67.06%. Net growth efficiency estimated NT-NA, NT-EA, HT-NA and HT-EA were represented as 75.75%, 75.94%, 74.68% and 74.49%. In this results, two ways could be considered to produce an efficient artificial seed of sandfish. To hasten the growth of sandfish juvenile, heated seawater (HT) and enriched Artemia nauplii (EA) should be inputted to reared condition. And to increase the energy efficiency, natural seawater (NT) and enriched Artemia nauplii (EA) should be inputted to reared condition.
