“…As confused synonymy started to clarify in the late 60s, another systematic problem was created by the fallacious suggestion that S. maena and S. flexuosa constitute eco-phenotypes (or habitat coloration forms) of the same species (Arculeo et al, 1996;Pollard and Pichot, 1971). Despite the fact that since mid80s several researchers agreed in the recognition of three valid Spicara species in the Mediterranean Sea (Golani et al, 2006;Papakonstantinou, 1988;Tortonese, 1986), discrimination difficulties are still confronted (Minos et al, 2013), and have possibly favored the partitioning of specimens of one species in studies of another (Dul ci c et al, 2003). Recently, a study of S. maena and S. flexuosa with specimens from the Thermaikos Gulf (North Aegean) revealed useful inter-specific sequence polymorphism of the 16S ribosomal RNA gene (Imsiridou et al, 2011).…”

“…Particularly the use of species-specific primers is considered an advantageous method for the routine analysis of numerous samples, especially in discrimination studies that include small number of species (Hyde et al, 2005;Michelini et al, 2007). Therefore, several assays with species-specific primers have been applied in biological and ecological studies (Ma et al, 2012;Matsui et al, 2012;Piergiorge et al, 2014).…”

After being stable for nearly a century, the taxonomic history of the genus Xiphopenaeus has been marked by many changes in the last three decades. The taxonomic status of the Atlantic species has a low resolution, and many species are still undefined and grouped as cryptic species. Here we employed an integrative approach to define the species of Xiphopenaeus and the morphological characters needed to differentiate them. We combined the analyses of two molecular markers (COI and 16 S rDNA), scanning electron microscopy and light microscopy. Based on specimens from 17 localities from the Atlantic and Pacific oceans, we detected five divergent genetic groups, three in the Atlantic (A1, A2, A3) and two in the Pacific (P1, P2). Male secondary sexual characters were able to differentiate four out of the five genetic groups. Group A1 corresponds to X. kroyeri, and A2 and A3 correspond to new species. We redescribed the genus and two new species are described and illustrated: Xiphopenaeus dincao nov. sp. (A2) and Xiphopenaeus baueri nov. sp. (A3). Since the holotype of X. riveti was missing and the specimen analysed from group P2 was a female, the status of the species of Xiphopenaeus from the Pacific remains unresolved.

“…There is currently a closure season (March-May) in compliance with a legal norm (IBAMA, 2008) that covers the Southern region from Espírito Santo to Rio Grande do Sul States. However, this geographical area is considered excessively large and, according to genetic studies, it comprises more than one different stock/population (Gusmão et al 2006(Gusmão et al , 2013Franscisco 2009, Piergiorge et al 2014. Moreover, the closure season was originally established rather to protect the pink-shrimp (Farfantepenaus paulensis, F. brasiliensis) from the estuaries to the ocean (D'Incao 1991).…”

Knowledge of the difficulties, costs, and territorial issues surrounding fishing communities seems crucial to achieve sustainable development goals in marine and coastal zones. However, such knowledge is not always available, sufficient, or even identifiable. The seabob-shrimp small-scale fisheries in the shallow waters of the State of São Paulo, in Southeastern Brazil, plays an important role in coastal livelihoods, providing social and economic benefits for a number of local communities and a premium source of regional seafood. Around 4000 fish-workers produce supplies for restaurants, fishmongers and supermarkets in coastal towns with about 2 million inhabitants. Nevertheless, harbor and naval mooring, the construction of pipelines, sewage disposal, controversial seasonal closures, and marine spatial zoning have all restricted the activity. A territorial approach is here proposed to examine the timeline of vertically implemented laws/regulations that may have resulted in a decrease of territories formerly available to that fisheries, accompanied by a comprehensive outlook of the overall policy context. The shrinkage of fishing territories has been evidenced and the kind of territorial loss detected does not seem to be implicit in cost analysis of fisheries, ecosystem services, or compensation. Top-down policies and a misunderstanding of environmental mitigation programs appear to have been contributing to increasing conflicts, mining multi-stakeholder processes and social justice in contrast to the ascendant economic growth of both the oil and gas and port industries. While economic and political pressures seem to shape current fishing territories, the recognition of the diversity of interests and power asymmetries in coastal zones directs our attention to a vital, often ignored, dimension of social reality. Institutional challenges and recommendations, such as territorial use rights and legal innovations are discussed, adding value to the self-organization of local communities for an effective process of balanced power both within and outside legal marine protected areas.
