Abstract

The present study is the first to provide data on the reproductive biology of cuckoo ray Leucoraja naevus in Portuguese continental waters. No difference in size at maturity was detected between sexes, which was estimated as 56 cm total length. Spawning occurs all year round, but maximum activity was during winter months. Maximum fecundity is c. 63 eggs female−1 year−1. Encapsulated eggs are released in batches, nine in total with a mean number of seven extruded eggs in each batch.
