Recent expansion of Northeast Atlantic and Mediterranean populations of Melicertus (Penaeus) kerathurus (Crustacea: Decapoda).
2009
We analysed the genetic diversity of Melicertus kerathurus (Penaeidae), a commercially valuable penaeid shrimp that is distributed in the Mediterranean Sea and eastern Atlantic Ocean. We examined the polymorphism of a 494 bp DNA segment of the mitochondrial COI region in 173 individuals, sampled in nine Mediterranean and two Atlantic samples, covering the whole range of the species from the tropical waters of the Gulf of Guinea to the eastern part of the Mediterranean Sea. The mean nucleotide and haplotype diversities were π = 0.00275 and h = 0.718, respectively, for the global data set, with the highest values occurring in the African samples and the lowest in the Adriatic Sea. A clear sam…
Stock assessement and management by restocking of Melicertus kerathurus (Forskäl, 1775) in the shallow coastal waters at Selinunte
2011
From 1998 to 2010, monitoring was performed on the catch and fishing effort of Melicerctus kerathurus by the artisanal fleet based at the port at Marinella di Selinunte which operates in the wide gulf between Capo San Marco and Capo Granitola along the southwestern coast of Sicily. In 2004, a repopulation experiment with Melicerctus kerathurus post-larvae raised in an aquaculture plant from wild indigenous breeders was carried out in this area. The catch and cpue, in both number of specimens and in yield, were practically doubled in 2005. From 2006, catch and cpue returned to levels observed in the years prior to 2005. With the exception of 2004 and 2005, the stock of Melicerctus kerathurus…
