Abstract
INTRODUCTION In Brazil, the Atlantic seabob shrimp, Xiphopenaeus kroyer is.l. (Heller, 1862), is one of the most important commercial species, with average annual production between 2010 and 2016 estimated in [...]
In 2004, Xiphopenaeus kroyeri, one of major species in commercial fisheries in Brazil was included in the list of brazilian overfished species and, in 2006, two cryptic species were identified in the Atlantic Ocean by molecular approaches: Xiphopenaeus sp. I and II. In 2019, Carvalho-Batista et al. described both Xiphopenaeus sp. I and Xiphopenaeus sp. II and these species were named X. kroyeri and X. dincao, respectively. This study aimed at performing morphometric analysis in order to identify potential fishing stocks of X. kroyeri sensu strictum along Brazilian coast. The results obtained separate Caravelas, Atafona and Balneario Camboriu from all the other populations studied and showed three groups: Ubatuba, Nova Almeida; Ubatuba, Cananeia; Ubatuba, Santos. These results indicate that the maritime limits practiced in closed seasons along Brazil are embracing the detected morphometric stock boundaries observed for Xiphopenaeus kroyeris.s. KEY WORDS: Xiphopenaeuskroyeri; Geometric morphometry; Population structure.
