SHORT COMMUNICATION: Relationship between daily survival rates of larval Japanese anchovy (Engraulis japonicus) and concentrations of copepod nauplii in the Seto Inland Sea, Japan

We attempted to estimate the survival rates of larval cohorts (3-15 mm in body length) of the Japanese anchovy Engraulis japonicus population in Hiuchi-nada, Seto Inland Sea, Japan, and examined the relationship to their food availability. The survival rates were directly calculated from the change in larval density during the survey. The estimated daily survival rate ranged between 0 and 89% d-1, but increased with the increase in the mean concentration of small-sized copepod nauplii (
