Annual landings from 1994 to 2000 of Kesennuma, Shizugawa, Onagawa and Ishinomaki fish markets accounted for more than 98% of those of Miyagi Pref. They showed no marked changes. Rank correlations of monthly landing ratios (%) were significant within and among the four fish markets, showing that 40.3% of the annual landings was caught in June, 36.3% in July, and 8.7% in August. Annual landings of Seisho district in Kanagawa Pref. were an order of magnitude larger in 1993 to 2000, as compared with those in 1986 to 1992. At Seisho, rank correlations of monthly landing ratios were significant among 8 of 15 years ; 30.4% was caught in December, 22.5% in November and 15.2% in April. Rank correlations of monthly landing ratios in 2000 were significant between Shonan and Miura districts in Kanagawa Pref. ; 64.7% of annual landings was caught in May and 32.5% in June. Annual landings in Shizuoka Pref. were an order of magnitude larger in 1997 to 2000 than those in 1991 to 1996. Rank correlations of monthly landing ratios were not significant within and among five major fishing grounds except within Akaishi fishing ground, showing no regularity of monthly landings in Shizuoka Pref. In addition, there was no common seasonality in landings of molids among the five fishing grounds. Landing statistics for the two years of 1999 and 2000 at Tsuruga, Hayase, and Obama Branches of Fisheries Cooperation in Fukui Pref. showed that the landings were concentrated in December (82.8% of the annual landing) and January (11.4%).}, pages = {27--33}, title = {4県におけるマンボウ類の漁獲状況}, volume = {51}, year = {} }
