Fecundity, an overlooked life-history trait for coastal management of commercial molluscs?

Frontiers in Marine Science, 2023
Gonadal development in limpets is well-known. However, the integration of fecundity data on coastal management actions remains overlooked. Here, we use fecundity of two exploited limpets (Patella ordinaria and P. aspera) to demonstrate its potential as a
