库欣（1966）报道了黑线鳕补充与北海哲水蚤丰度之间的相关性，但在1962年的超大型年级中，这种相关性失败了，而1962年的超大型年级开始了鳕爆发。这篇文章还报道了鳕补充和虾类在钆爆发期间的另一个相关性，但如果包括早期的观测（1962年之前），它就失败了。比较1948年至1961年与1962年至1978年的一个月的延迟在季节性生产的高峰ofCalanusis证明。计算出每年虾脊茧蜂的产量高峰比推测的孵化日期推迟数月。鳕鱼招聘显着相关，这一指数的延迟为1954年至1977年期间，在整个期间之前和期间的钆爆发;如果平均招聘年与相同的延迟指数的延迟，大部分的方差占。鳕鱼招聘延迟和onCalanusabundance的多元回归计算和另一个鳕鱼招聘延迟，Calanusabundance，3月的海水温度;在后一种情况下，四分之三的方差占。北海的钆爆发可能是由自然变化引起的。
Cushing (1966) reported a correlation between haddock recruitment and the abundance ofCalanusin the North Sea which failed with the very large year class of 1962 which started the gadoid outburst. This note reports another correlation between cod recruitment andCalanusduring the gadoid outburst, but it fails if earlier observations (before 1962) are included. Comparing 1948 to 1961 with 1962 to 1978 a delay of one month in the peak of seasonal production ofCalanusis demonstrated. In each year a delay in peak production ofCalanusin months from the presumed date of hatching was calculated. Cod recruitment was significantly correlated with this index of delay for the period 1954 to 1977, across the periods before and during the gadoid outburst; if the mean recruitment in years with the same delay is related to the index of delay, most of the variance is accounted for. A multiple regression of cod recruitment on delay and onCalanusabundance was calculated and another of cod recruitment on delay,Calanusabundance, and March sea temperature; in the latter case three quarters of the variance was accounted for. The gadoid outburst in the North Sea was probably started by a natural change.
