Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...

Community science datasets identify the spatial occurrence and hotspots of flapper skate (Dipturus intermedius)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The flapper skate, Dipturus intermedius (Parnell, 1837), is a large‐bodied, slow‐growing and late‐maturing, Critically Endangered elasmobranch with a constrained population distribution. Here, we use two longitudinal community science datasets to investigate the occurrence of flapper skates in Irish waters. The two datasets are as follows: the

On the conflict between science and ethics: the case of the moggel, Labeo umbratus (Teleostei: Cyprinidae) from South Africa

open access: yesJournal of Fish Biology, EarlyView.
Abstract Recent molecular evidence showed that Labeo umbratus comprises two allopatrically distributed genetic lineages, a northern lineage confined to the Orange‐Vaal River system where this species was originally described and a southern lineage with three geographically separated haplogroups (western, central and eastern) distributed across multiple

Biological aspects and population dynamics of the European pilchard Sardina pilchardus (Walbaum, 1792) in the southeastern Mediterranean waters

open access: yesJournal of Fish Biology, EarlyView.
Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.
