LED 집어등의 어획성능은 2010년 9-10월과 2011년 10월에 조업한 영락호 (16톤)와 소망호 (9.77톤)의 오징어 채낚기어선을 이용하여 대조어선과 비교․분석하였고 연료소비량도 조사하였다. LED 집어등의 광력은 영락호의 경우 25.8kW, 소망호 32kW이었고 MH 선박인 대조어선은 각각 105kW와 81kW이었다. LED 선박인 영락호의 평균 오징어 어획량은 대조어선의 39.2%였으나 소망호의 경우는 대조어선의 78.7%로 향상되었다(p<0.05). 영락호 선원에 의한 어획량은 자동 조획기의 것보다 평균 2.6배가 많았다. MH 선박의 선원에 의한 어획량은 자동 조획기의 것보다 평균 1.8배가 많았다. 이는 자동 조획기와 선원이 사용하는 오징어낚시의 종류가 다르지만 자동 조획기의 개선도 필요함을 알 수 있다. 자동 조획기 1대당과 선원 1인당 어획량의 합한 비교에서는 LED 선박인 영락호의 어획비율은 MH 선박의 17.5-152.2%로서 평균 61.1%였다. 소망호의 경우는 MH 선박의 6.7-127.6%로서 평균 73.1%였으나 LED 집어등의 광력 차이에 의한 영락호와 소망호의 어획량 차이는 없는 것으로 나타났으며, 앞으로 LED 집어등의 광력 증가와 어선 톤수별 적정광력도 파악할 필요가 있었다. 소망호의 연료 소비량은 출항에서 입항까지 평균 475.7ℓ이고 그 가운데 조업 중의 평균 연료 소비량이 109.6ℓ로 23.0%였으며, 조업시간당 연료소비량은 평균 9.7ℓ로서 LED 집어등의 도입은 조업시 연료 소비량을 대폭 절감되게 할 것이다.
Abstract
This study has conducted a comparative analysis on the fishing efficiency of LED fishing lamps by squid jigging boats, the Yeongrak-ho (16 tons) and Somang-ho (9.77 tons), which operated during September and October 2010 and during October 2011, comparing with MH(Metal Halide) fishing lamp-equipped fishing vessels. This study has also examined boat’s fuel consumption level. The light powers of LED fishing lamps of the Yeongrak-ho and Somang-ho were 25.8kW and 32kW, respectively. Those of the MH fishing vessels, that is, the MH fishing lamp-equipped fishing vessels, were 105kW and 81kW, respectively. The average squid catch in number of an LED vessel, Yeongrak-ho, was 39.2% of the MH fishing lamp-equipped fishing vessels; however, that of the Somang-ho improved to 78.7% of the MH fishing lamp-equipped vessels. Average catch in number by Yeongrak-ho crew was 2.6 times more than catch in number by automatic jigging machines. Average catch in number by MH fishing vessel crew was 1.8 times more than that by automatic jigging machines. An LED vessel, Yeongrak-ho’s fishing rate was 17.5%-152.2% of the MH fishing vessels, that is, 61.1% on average, in comparison of combined catch in number per automatic jigging machine and per crewmember. Somang-ho’s fishing rate was 6.7%-127.6% of the MH fishing vessels, that is, 73.1% on average. The average fuel consumption level of the Somang-ho, throughout its departure from to arrival at the port, was 475.7ℓ, and that during fishing hours was 109.6ℓ, or 23.0% of the total fuel consumption level. Somang-ho’s fuel consumption level per fishing hour was 9.7ℓ on average.
