Three shallow inshore records of Cornish blackfish Schedophilus medusophagus from Galician waters (NW Spain) are reported. S. medusophagus is a relatively rare mesopelagic species in the NE Atlantic. Adult specimens are mainly found in medium-depth waters (300-900 m). Their presence in shallower coastal waters is very unusual. An historical review of North Atlantic shallow inshore records was made. Reproductive and stomach content analyses were investigated and related to two proposed inshore migration hypotheses. Resulting from these investigations, the first description of gametogenesis and gonadal development organization of this species is presented. Ovary development was found to be group-synchronous, with a highly synchronous population of larger follicles. Testicular tissue was found to be lobular type. Since no conclusive evidence was found to support either of the two proposed hypotheses an additional hypothesis related to increasing sea water temperatures was proposed.

A new record of Lepidion schmidti (Gadiformes: Moridae) is reported from the Bay of Biscay (north-east Atlantic Ocean). Lepidion schmidti is a rare and poorly known species, scarcely described in the ichthyological literature. Morphometric and meristic characteristics of the specimen are given. A compilation of the specimens caught in the north-east Atlantic Ocean was carried out and the current status of the species in Atlantic waters is discussed. Lepidion schmidti is characterized mainly by the presence of an inverted V-shaped patch of vomerine teeth and a V-shaped crest on the dorsal surface of the head with the apex anterior. The presence of supernumerary anal fin rays in this species is described for the first time. The results obtained confirm the presence of L. schmidti from the north-east Atlantic Ocean. © 2011 The Authors. Journal of Fish Biology © 2011 The Fisheries Society of the British Isles.
