The haddock (Melanogrammus aeglefinus) stock of the Georges Bank region of the US Northeast Continental Shelf displays a pattern of large, episodic recruitments. Among the hypothesized controlling mechanisms is the idea that recruitment events are related to provisioning of prespawning haddock by the fall bloom the year before. With the occurrence of a recent large recruitment event in 2013, it would be prudent to retest this hypothesis. Fall bloom magnitude was positively correlated (r = 0.645, p = 0.005) with haddock survivor ratio (recruits per spawning biomass), including data from the 2013 recruitment. This relationship identifies a pathway of bottom-up control of a resource species, thus focusing concern over recent changes in lower trophic-level productivity.

乔治银行黑线鳕招募控制供给假设的检验

美国东北大陆架乔治银行地区的黑线鳕 (Melanogrammus aeglefinus) 种群表现出大规模、间歇性招募的模式。在假设的控制机制中，有一种观点认为，招募事件与前一年秋季开花前提供产卵前黑线鳕有关。随着最近 2013 年发生的大型招聘事件，重新检验这一假设将是明智之举。秋季盛开程度与黑线鳕存活率（每个产卵生物量的新成员）呈正相关（r = 0.645，p = 0.005），包括 2013 年招募的数据。这种关系确定了一种自下而上控制资源物种的途径，因此关注最近较低营养级生产力的变化。
