Since the late 1990s, walleye pollock Gadus chalcogrammus fisheries in Korean waters have been considered collapsed. Although many fisheries scientists suspect that the collapse might have been triggered by overexploitation of juvenile pollock or environmental changes, such conjectures have been nei...

명태의 적정 서식 수온 범위는? | 이는 비교적 따뜻해진 동해의 수온이 냉수성 어종인 명태의 서식에 악영향을 미쳤을 것이라는 추측을 이끌었으나 동해 명태의 서식수온과 수심에 관한 정밀한 연구가 수행되지 않았기 때문에 이를 뒷받침할 과학적 근거는 미미한 실정이다. 현재까지 동해 명태의 서식수온과 수심에 관하여 보고된 연구 중일부를 살펴보면, Nishimura (1969)가 동해 명태의 적정 서식 수온 범위를 2-5°C이라 하였으며 약 200 m 수심에서 형성되는 영구 수온약층(permanent thermocline) 아래의 수온이 약 5°C 이므로 이들의 서식 수심은 200 m보다 깊을 것이라고 하였다. 그러나 Gong and Zhang (1986)은 동해연안에 서식하는 명태의 서식수심은 계절별로 다르며 이 또한 동한난류의 강세에 따라 변동된다고 하였고 Kooka et al. | |
우리나라 동해의 명태 어업현황은? | 우리나라 동해의 명태(Gadus chalcogrammus)어업은 1990 년대 후반 이후로 붕괴 된 것으로 여겨지고 있다. 1981년 약 17 만톤에 이르던 명태 어획량이 1995년에는 채 1만톤이 되지 않았으며 이후, 지속적인 감소를 거쳐 2008년의 어획량이 1톤 미만이였다는 사실은 동해 명태자원의 고갈을 시사하였다. 이러한 명태자원의 고갈 원인으로는 기후변화에 의한 동해의 해양 환경 변화와 노가리라 불리는 소형명태의 무분별한 어획이 주로 거론되고 있으나 아직 정확한 원인은 밝혀지지 않았다. | |
명태의 서식수심과 수온약층과의 관계는? | 이는 비교적 따뜻해진 동해의 수온이 냉수성 어종인 명태의 서식에 악영향을 미쳤을 것이라는 추측을 이끌었으나 동해 명태의 서식수온과 수심에 관한 정밀한 연구가 수행되지 않았기 때문에 이를 뒷받침할 과학적 근거는 미미한 실정이다. 현재까지 동해 명태의 서식수온과 수심에 관하여 보고된 연구 중일부를 살펴보면, Nishimura (1969)가 동해 명태의 적정 서식 수온 범위를 2-5°C이라 하였으며 약 200 m 수심에서 형성되는 영구 수온약층(permanent thermocline) 아래의 수온이 약 5°C 이므로 이들의 서식 수심은 200 m보다 깊을 것이라고 하였다. 그러나 Gong and Zhang (1986)은 동해연안에 서식하는 명태의 서식수심은 계절별로 다르며 이 또한 동한난류의 강세에 따라 변동된다고 하였고 Kooka et al. |
