Sassa and Tsukamoto (2010) described that Scomber spp. larvae are concentrated while in the upper 30-m layer, with peak densities at a depth of ∼20 m from the southern East China Sea. Accordingly, the h2o temperature and salinity values recorded at 20 m depth at Each and every station have been employed for the Assessment. The chlorophyll a focus and abundance of prey have been considered proxies for foodstuff availability at throughout the time of seize.
