Abstract: Entre el mes de septiembre del 2009 a agosto del 2010, treinta y seis especímenes de Rhinobatos planiceps (Garman, 1880) “pez guitarra del pacífico” fueron adquiridos del Terminal Pesquero de Chorrillos, Lima-Perú para la evaluación de la dinámica poblacional de su fauna metazoa parasitaria. De los peces examinados 14 fueron hembras y 22 fueron machos. Los peces mostraron una longitud total promedio de 85,0±19,3 cm (27 a 125). Los parásitos metazoos fueron colectados y censados empleando los protocolos parasit… Show more

Rhino rays (Order Rhinopristiformes) are one of the most threatened vertebrate groups. Despite overfishing being recognised as the greatest threat to this group, a comprehensive assessment of the fisheries and types of fishing gear that rhino rays interact with is lacking. We reviewed published and grey literature (n = 116 references) to evaluate interactions between rhino rays and fisheries, determine gear types most responsible for their capture, and species for which most interactions occur by region. Interactions (n = 420) were reported from 37 of 88 range states, for 52 of 68 known species. Combined, 59% of the literature reported interactions from trawlers and gillnets. Wedgefishes (Rhinidae) were the most reported family (29%) and bowmouth guitarfish (Rhina ancylostomus) the most reported species (9.5%). Asia accounted for half of interactions (n = 211), with 67% of the literature from unspecified gear (e.g., mixed landings), masking gear-specific interactions. Data quality was variable, with the highest resolution in countries with lower species diversity and where species are least imperiled (e.g., Australia). Discard mortality and physiological effects of capture are poorly known with data available for 25% of species (almost exclusively from Australia and the Americas). While additional data are urgently required to quantify the true extent of rhino ray catch globally, reducing fisheries mortality is a priority and key to address declining populations. Recommendations include prioritizing spatial management in critical habitats (e.g., nursery areas), expansion in the use of proven bycatch reduction devices, encouraging safe release and handling, and addressing drivers of retention and trade.

This review examines—with a focus on Peru—the distribution, life-history, ecology, fisheries, historic and contemporary cultural importance, commerce, and management of the Pacific guitarfish Pseudobatos planiceps. In the eastern Pacific, Peru represents its most important habitats. The only 2 identified Important Shark and Ray Areas for this species are in Peru for feeding purposes. Other critical habitats are unidentified (e.g. reproductive). Most demographic parameters are unknown, since only length-at-maturity and fecundity have been determined. This species is a mesopredator that feeds on benthic invertebrates but also on Peruvian anchoveta. This trophic plasticity is unique among species within this genus. Globally, Peru has one of the longest species-specific landing datasets (56 yr) and one of the largest catches among countries that report guitarfish landings. This dataset shows a 98% decrease in landings from a peak in 1981 to a low in 2004, while fishing effort increased during this period, suggesting that depletion occurred in the early 1980s. The Pacific guitarfish is the third most landed ray species by artisanal fisheries in Peru, mainly between the central and northern regions. Adults are mainly caught using gillnets and as bycatch in trawling fisheries. Mid-northern Peru has a millennia-old tradition in Pacific guitarfish capture and consumption, and catch is not regulated. Along its distributional range, fisheries in Peru are the main cause of population decline; therefore, there is an urgency to halt this trend to protect the Pacific guitarfish. This review establishes a baseline, identifies information gaps, and provides recommendations to guide research and management for the species.

Monogeneans are flatworm parasites that infest fish gills primarily but can also infect various other vertebrates, including amphibians, aquatic reptiles, mammals like hippos, and occasionally invertebrates like copepods, isopods, and cephalopods. Despite their remarkable diversity, our knowledge of monogenean parasites in Peru remains significantly limited, resulting in substantial gaps in our comprehension of their taxonomic identities, host associations, and geographic distribution. To address these knowledge deficits, we present an extensively curated checklist of monogeneans associated with aquatic vertebrates in Peru. This comprehensive compilation is derived from meticulous literature surveys, the examination of specimens deposited in both international and national collections, and the inclusion of additional freshly collected specimens. The checklist offers a thorough repository of data encompassing the diversity, host associations, and geographical distribution of these parasites. Taxonomic discrepancies are addressed through a critical review of the existing literature, supplemented by the direct examination of specimens, including type or voucher specimens, deposited within scientific collections. Additionally, we provide data on the DNA sequences of individual taxa. The compiled list comprises records of 358 monogenean species, including 270 valid species and 88 taxa identified at the family or generic level, all reported across 145 host species in Peru. Predominantly, these parasitic species exhibit associations within fish, with 335 infecting teleosts and 20 affecting chondrichthyans. Three monogenean species have been documented as infecting amphibians, namely Mesopolystoma samiriensis, Polistoma sp. and Wetapolystoma almae. Among the monogeneans reported, 141 were found in marine environments and 214 in freshwater environments. The most diverse families were Dactylogyridae and Diplectanidae, comprising 217 and 24 species, respectively. The hosts that harbored the highest number of monogeneans were Pygocentrus nattereri (with 23 species), followed by Stellifer minor (13 spp.) and Triportheus angulatus (11 spp.). We detected many species that do not have any material deposited in a scientific collection due to the loss or deactivation of the collection. These findings represent only a fraction of the potential diversity, considering the wide variety of aquatic vertebrate hosts inhabiting the tropical and subtropical regions of Peru.
