초록

본 연구는 실내외 양식방법에 따른 미꾸라지 양식장 모니터링과 성장특성을 조사하여 국내 미꾸라지 양식산업에 대한 기초자료를 확보하고자 수행하였다. 조사는 2017년 8월부터 2019년 10월까지 실내 양식장 1개소 (D-site), 실외양식장 2개소 (P1-site, P2-site)를 선정하여 수행하였다. 성장도 측정결과를 토대로 WG (weight gain), DWG (daily weight gain), and SWG (specific weight gain) 분석한 결과 D-site에서는 175.27±36.2%, 7.98±3.3%, 0.94±0.2%, P1-site에서 320±34%, 4.07±0.6%, 0.55±0.1%, P2-site에서 295.9±53%, 4.15±0.5%, 0.62±0.1%로 나타났다. WG는 실외노지 양식장(P1-Site과 P2-site)에서 높았지만 DWG와 SWG는 실내양식장(D-site)에서 높게 나타났다. 본 조사 결과의 차이는 실내외 양식방법에 따른 성장도, 수질환경, 출하시기 및 횟수 차이로 인한 것으로 판단된다. 특히 실외 양식은 출하시기까지 1년 이상 소요되었으나 실내 양식은 1년에 3회의 출하가 가능한 것으로 나타났다.

The objective of the present study was to investigate fish farm and growth performances of Chinese muddy loach (Misgurnus mizolepis) under indoor and outdoor aquaculture conditions for the domestic loach aquaculture industry. The investigation was conducted from August 2017 to October 2019 at one indoor farm (D-site) and two outdoor farms (P1-site and P2-site). Results showed that WG (weight gain), DWG (daily weight gain), and SWG (specific weight gain) based on growth measurements were 175.27±36.2%, 7.98±3.3%, and 0.94±0.2% at D-site, 320±34%, 4.07±0.6%, and 0.55±0.1% at P1-site, and 295.9±53%, 4.15±0.5%, and 0.62±0.1% at P2-site, respectively. WG was higher in outdoor farms (P1-site and P2-site), while DWG and SWG were higher in the indoor farm (D-site). Such differences of the present study might be due to differences in growth, water quality, plant and sale frequency depending on aquaculture types. In particular, outdoor farms takes more than a year to have sales whereas indoor farms can have sales three times in a year.
