AB: Abstract
    Daily catch data of coastal squid jigging boats, their light
    source output for fishing lamps and monthly mean wholesale prices
    of squid were collected from five fishing ports (Hakodate, Sado
    Island, Noto, Sakaiminato, and Tsushima) in Japan, for a purpose
    of evaluating optimum light source output, which created a maximum
    economic yield. The daily income were estimated from the
    relationship between daily catch data and monthly mean wholesale
    prices of squid. Then, the optimum light source output was
    calculated from the relationship between daily income and daily
    lighting expenses by each fishing management conditions. The
    results show that daily income and daily lighting expenses were
    significantly increased as light source output for fishing lamps
    were increased. The lower light source output which obtained by
    each fishing management conditions was advantageous when lighting
    cost become more expensive or wholesale price become cheaper then
    ever.
