Abstract

At Pyropia farms, organic acid treatments have enhanced productivity and quality by removing pest algae (such as Ulva spp. and diatoms) and reducing the occurrence of diseases. Ulva spp. attaches to the Pyropia nets competing for inorganic nutrients & space and diminishing productivity. Additionally, the presence of attached contaminants (such as diatoms and middy particles) on the Pyropia nets negatively affects the quality of Pyropia. This study investigated the effects of removing Ulva linza and washing the Pyropia yezoensis nets using an activating treatment agent (organic acid and highly saline solution) with an air bubble device. The results of measuring the dead cell ratios after treatment under different conditions showed that the dead cell ratio of U. linza did not significantly increase when the air bubble device combined the activating treatment agent with the activating treatment agent alone. When washing the P. yezoensis nets, the air bubble device was about 19-37% more effective than the activating treatment agent alone. The findings of this study suggest that the air bubble device enhances the efficacy of the activating treatment agent, resulting in the effective cleaning of the Pyropia nets.

본 연구에서는 김활성처리제와 부가장치인 공기방울처리장치의 효과를 검증하고자 양식현장에서 잎파래 제거와 부착 이물질 세척 효과를 조사하였다. 그 결과 김활성처리제만 처리하였을 때보다 물리적 처리방법인 공기방울처리장치를 혼합하여 처리하였을 때 잎파래 제거에 유의적인 영향을 미치지는 않았으나 김 양식망의 이물질 세척 효과는 향상되었다. 이러한 연구 결과를 통해 공기방울처리장치를 혼합 사용한다면 김활성처리제의 사용량을 줄일 수 있으며 친환경적으로 이물질을 제거하여 김의 생산성과 품질을 향상시킬 수 있을 것으로 판단된다.
