Animals show among-individual variation in behaviors, including migration behaviors, which are often repeatable across time periods and contexts, commonly termed “personality.” These behaviors can be correlated, forming a behavioral syndrome. In this study, we assessed the repeatability and correlation of different behavioral traits, i.e., boldness, exploration, and sociality, and the link to feeding migration patterns in Atlantic cod juveniles. To do so, we collected repeated measurements within two short-term (3 days) and two long-term (2 months) intervals of these personality traits and genotypes of the Pan I locus, which is correlated with feeding migration patterns in this species. We found high repeatabilities for exploration behavior in the short- and long-term intervals, and a trend for the relationship between exploration and the Pan I locus. Boldness and sociality were only repeatable in the second short-term interval indicating a possible development of stability over time and did not show a relation with the Pan I locus. We found no indication of behavioral syndromes among the studied traits. We were unable to identify the existence of a migration syndrome for the frontal genotype, which is the reason that the link between personality and migration remains inconclusive, but we demonstrated a possible link between exploration and the Pan I genotype. This supports the need for further research that should focus on the effect of exploration tendency and other personality traits on cod movement, including the migratory (frontal) ecotype to develop management strategies based on behavioral units, rather than treating the population as a single homogeneous stock.

幼年大西洋鳕鱼生态型的个性及其对渔业管理的影响

动物表现出个体间的行为差异，包括迁徙行为，这些行为通常在不同时间段和背景下可重复，通常称为“个性”。这些行为可以相互关联，形成行为综合症。在这项研究中，我们评估了不同行为特征（即大胆、探索和社交）的重复性和相关性，以及与大西洋鳕鱼幼鱼摄食迁移模式的联系。为此，我们在两个短期（3 天）和两个长期（2 个月）间隔内收集了 Pan 的这些人格特征和基因型的重复测量值I 基因座，与该物种的摄食迁移模式相关。我们发现短期和长期间隔内探索行为的高重复性，以及探索与Pan I 轨迹之间关系的趋势。大胆和社交仅在第二个短期间隔内可重复，表明随着时间的推移可能会出现稳定性发展，并且与Pan I 基因座没有关系。我们在所研究的特征中没有发现行为综合症的迹象。我们无法确定额叶基因型是否存在迁移综合症，这就是人格与迁移之间的联系尚无定论的原因，但我们证明了探索与 Pan 之间可能存在联系我基因型。这支持需要进一步研究，重点关注探索倾向和其他性格特征对鳕鱼运动的影响，包括洄游（额叶）生态型，以制定基于行为单位的管理策略，而不是将种群视为单一的同质种群.
