Abstract

Sizes of coastal squid jogging boats, their light source output for fishing lamps and daily catch data were collected, for a purpose of evaluating factors on fishing boats, which affect to the squid catch, from four fishing ports (Hakodate, Sado Island, Noto and Tsushima) in Japan. The catch amount was increased as boat sizes and their light source output of fishing lamps were increased up to 100$\~$200 kW class and 11$\~$15 gross tonnage class. The relationship between catch per unit efforts y (box/machine/day), gross tonnage x_{1}, (GT) and light source output for fishing lamps x_2 (kW) is expressed as following formula; $y=4.091+0.18x_1+0.0019x_2$. Thus, 0.1819 boxes of squid catch can be expected, when light source output for fishing lamps increases for 1 kW $(x_2{\leq}200)$ and boat size 1 GT ($x_1\leq15$). It is considered that the boat size which created a shadow area under the jigging boat, is important factor affecting to catch amount, Because larger shadow area created by bigger boat has a possibility to let more squid stay there.

일본 홋카이도 하코다테, 니이가타현 사도 ,이시카와현 노토마치 및 나가사키현쯔시마 지역에서 소형 오징어 채낚기 어선의 톤수와 집어등 광원 출력 및 각 어선의 일별 연간 어획량 자료를 수집하여, 어선의 톤수와 집어등 광원 출력이 단위 노력당 어획량에 미치는 영향에 대해서 검토하였다. 어선이 설비하고 있는 집어등 광원 출력은 어선의 톤수가 증가함에 따라 증가하는 경향을 보였다 어선의 집어등 광원 출력 계급별 어획량 및 어선의 톤수 계급별 어획량은 집어등 광원 출력과 어선의 톤수계급이 증가함에 따라 단위 노력당 어획량도 증가하였으며, 어선의 어획 효율은 11$\~$15톤급 어선이 100-200kw의 집어등 광원 출력 조건을 갖는 경우가 좋은 결과를 나타내었다. 이것은 소형 오징어 채낚기 어선의 경우, 집어등 광원 출력을 200kw, 어선의 톤수를 15톤까지 증가시키는 범위 내에서 어획 효율의 증가를 기대할 수 있다는 것을 의미한다. 이상의 소형 오징어 채낚기 어선의 톤수 $(GT) x_1$와 집어등 광원출력 (kW) x,이 단위 노력당 어획량 (box/machine/day) y에 미치고 있는 관계를 다중 회귀 정규 방정식을 이용하여 표현하면 다음과 같은 관계식으로 정리할 수 있다.
