Summer plankton surveys were conducted in 2015–2017 to characterize the distribution and abundance of squid paralarvae in epipelagic waters of the northern Gulf of Mexico (Gulf). Paralarvae present at stations sampled were from 12 families, with the most abundant being Ommastrephidae (flying squids), Enoploteuthidae (armed squids) and Onychoteuthidae (hooked squids). Mean density and percent frequency of occurrence for squid paralarvae across all surveys was 8.8 paralarvae 1000 m⁻³ and 76%, respectively. Julian day, salinity, sea surface height (SSH) and time of day were identified as influential environmental variables in generalized additive models (GAMs). Paralarval densities peaked during early morning and late evening sampling times, which is in accord with diel vertical migration patterns. Densities increased in early July, in areas with low SSH and lower salinity (28–35 psu), indicating upwelling areas and proximity to inflow from the Mississippi River represent productive early life habitats for squid. Results suggest that oceanic squid spawn in the northern Gulf in the summer exploiting the position of mesoscale oceanographic features and the extension of freshwater discharges from the Mississippi River.

2015-2017 年进行了夏季浮游生物调查，以描述墨西哥湾北部（海湾）上层水域中鱿鱼副幼虫的分布和丰度。采样站出现的副幼虫来自 12 个科，数量最多的是 Ommastrephidae（飞乌贼）、Enoploteuthidae（武装乌贼）和 Onychoteuthidae（钩乌贼）。所有调查中鱿鱼副幼虫的平均密度和发生频率百分比为 8.8 副幼虫 1000 m ^-3和 76%，分别。在广义可加模型 (GAM) 中，儒略日、盐度、海面高度 (SSH) 和一天中的时间被确定为有影响的环境变量。Paralarval 密度在清晨和深夜采样时间达到峰值，这与日间垂直迁移模式一致。7 月初，在 SSH 和盐度较低 (28-35 psu) 的地区，密度增加，表明上升流区域和靠近密西西比河流入的地区代表了鱿鱼的早期生活栖息地。结果表明，利用中尺度海洋特征的位置和密西西比河淡水排放的延伸，海洋鱿鱼在夏季在海湾北部产卵。
