| 内容記述 | Studies on the mode of appearance of some fork-length (age) groups in the young mackerel distributed in the northeastern sea area of Japan were made based upon the materials collected from along the coastal areas from Joban to Hachinohe during the 1963 to 1969 fishery seasons. The results of the analysis of the characters in the fork-length frequency distribution of the materials were. 1) Observing the ranges of fork-length of the materials, the young mackerels were classified into five groups, that is, I, III, III, II and IIIII type, these are composed of all 0, mainly 0, mainly I, mainly mixing of I and II and mainly II age groups respectively. 2) From the tendencies of the seasonal and annual appearance of each type, several characteristic periods of each sea area were set up, viz; From Inubo to Shioya point area I period (early January~late May) ...... III, II type mainly and I II period (early June~late September) ...... I type mainly and III.II III period (early October~late December) ...... I, III.II type From Shioya to Kinkasan point area I period (early April~late October) ...... I.III type II period (early November~late March) ...... III.III type From Kinkasan~Kurosaki point area I period (middle May~early August) ...... II type II period (middle August~late September) ...... I.II type III period (early October~late November) ...... II type 3) Number of peaks, shape and range in fork-length frequencies of each material were examined to make clear the feature of the mixture of few age groups and different broods in the same year class. 4) The characteristics of appearance of the young mackerel in each season of each sea area were considered synthetically, and their pattern were summarized as shown in Table 11. 5) The landings of young mackerel in Fukushima Prefecture (representative of Joban for the abundance of the catches in the winter period) and in Iwate Prefecture (representative of Sanriku in feeding period in the same year) were compared with each other, and it was recognized that high correlation existed between these two landngs. | |||||

| 内容記述 | 1963~'69年の7年間に得た体長組成を解析し,東北海区各海域におけるマサパ体長(年齢)群の出現様式を検討した.1)未成魚群を体長と年齢の対応より,I(O年魚)·IⅡ(O年魚主体)·ⅡII(I年魚主体)·Ⅱ(I·Ⅱ年魚)·II(Ⅱ年魚主体)の各型群に区分した.2) 各型群の季節·経年の出現傾向から各海域に次の各期を得た.犬吠崎~塩屋崎海域第Ⅰ期(1月上旬~5月下旬)II·Ⅱ型主体でI型の分布.第Ⅱ期(6月上旬~9月下旬)Ⅰ型主体でⅡI·Ⅱ型の分布.第Ⅲ期(10月上旬~12月下旬)Ⅰ·II·Ⅱ型の分布.塩屋崎~金華山海域第Ⅰ期(4月上旬~10月下旬)Ⅰ·I型の分布.第Ⅱ期(11月上期~3月下旬)II·II型の分布.金華山~黒崎海域第Ⅰ期(5月中旬~8月上旬)Ⅱ型の分布.第Ⅱ期(8月中旬~9月下旬)I·Ⅱ型の分布.第Ⅲ期(10月上旬~11月下旬)Ⅱ型の分布.3) 体長組成の特長型(モード数,分布型,範囲)を検討し,主として各年齢群,発生時期の異なる群の混合状態を解析した.4) 各期の特性,体長組成の特長型および各期に対応する生活年周期をとりまとめ,東北海区マサバ未成魚の出現様式の特性(第11表)を得た.5) 福島県(常磐沖を代表)および岩手県(三陸沿岸を代表)の未成魚陸揚量を年間の総陸揚量から区分し,さらに体長(年齢)群の出現時期別に明らかにした.その結果常磐沖越冬群と三陸沿岸索餌群の陸揚量に,1968年を除き正の相関関係が認められた. | |||||
