Abstract

This article investigates female morphological traits as predictors of fertility and hatching success in the limpet Patella aspera, a species with aquaculture potential but lacking broodstock quality assessment methods. The study measured body size, gonad development, and oocyte morphology in adult females, finding that larger female length and more mature gonads correlate positively with total oocyte number. Oocyte shape changes from polyhedral to spherical after extraction, and an alkaline bath treatment significantly improves hatching success by increasing the ratio of viable larvae in most females. Key predictors of larval viability include oocyte sphericity, chorion presence, and gonad oocyte density, suggesting these morphometric traits can serve as practical proxies for broodstock and gamete quality in hatchery production of P. aspera.
