Abstract

Domestic Manila clam production has been reduced due to coastline changes and environmental degradation, but aquaculture industry is facing difficulties caused by an increase in imports. It is important to recognize the integral habitat environment in order to do sustainable aquaculture. The habitat environment of Manila clams (Ruditapes philippinarum) is closely related to the productivity of aquaculture farms. This study investigated 3 indexes, survival (sediment type, hydrodynamic), growth (Chlorophyll a, DIN, DIP) and environment (water temperature, dissolved oxygen, sediment chemical oxygen demand, ignition loss) as indicators of habitat characteristics for a tidal flat farm in Geunso Bay (Pado and Beopsan) from June 2015 to May 2016. As a result, Pado (maximums.; sand 48.76 %, hydrodynamic 10.59 cm/s, Chlorophyll a 12.70 ug/L, exposure time 3 hours, DO 18.65 mg/L) had a higher sand content, faster current speed, more abundant nutrients and DO, providing more favorable conditions for Manila clams than Beopsan (maximums.; sand 37.40 %, hydrodynamic 6.02 cm/s, Chlorophyll a 6.41 ug/L, exposure time 7 hour, DO 14.81 mg/L). In fact, Pado showed a higher density than Beopsan. This study considered the habitat environments of Pado and Beopsan to provide a basis for optimal management practices and potential suitable sites in Geunso bay.

현재 국내바지락 양식 산업은 연안선 변화, 양식 환경악화로 생산량이 감소하는 반면, 수입량 급증으로 인한 어려움에 직면해 있다. 현 실태를 극복하고 지속적인 양식을 위해 서식환경을 종합적으로 이해하는 것이 중요하며, 바지락의 서식환경은 양식장의 생산력과 밀접한 관련이 있다. 본 연구에서는 2015년 6월부터 2016년 5월까지 근소만에 위치한 파도와 법산 갯벌어장에 대하여 생존(입도, 해수유동), 성장(Chlorophyll a, DIN, DIP, 노출시간), 환경(수온, DO, 퇴적물 COD, IL)을 이용하여 서식환경 특성을 구명하였다. 조사결과 파도(최대값; 모래함량 48.76 %, 해수 유속 10.59 cm/s, Chlorophyll a 12.70 ug/L, 노출시간 3시간, DO 18.65 mg/L)는 법산(최대값; 모래함량 37.40 %, 해수 유속 6.02 cm/s, Chlorophyll a 6.41 ug/L, 노출시간 7시간, DO 14.81 mg/L)보다 높은 유속과 모래함량, 풍부한 DO와 영양염으로 바지락 서식에 유리한 조건을 가지고 있었으며, 실제로도 더 높은 서식밀도를 나타내었다. 본 연구는 파도와 법산 바지락 서식지 환경을 파악하여 근소만 갯벌어장의 최적 관리 방안 및 잠재적 적지선정을 위한 기초자료로 활용될 수 있다.
