The regulatory and research landscape were evaluated toward identifying potential gaps that may be hindering conservation and management of batoids in Peru. Results showed that in the eastern Pacific, Peru ranked second, after Chile, for batoid landings from 1950 to 2015. Of the twenty-three species of marine batoids that interact with Peruvian fisheries, the most landed taxonomic groups, from 1997 to 2015, were: Myliobatis spp. (i.e., M. chilensis and M. peruvianus; 45% of batoids landings), Mobula spp. (primarily M. mobular, and secondarily M. thurstoni, M. munkiana, M. tarapacana; 28%), Pseudobatos planiceps (6%), and Hypanus dipterurus (6%). Most of these species are landed in northern Peru, where gillnets are the most-used fishing gear to capture them. Batoid landings occurred year-round; yet, for H. dipterurus and P. planiceps landings were highest during the austral summer. Only three management measures exist for batoids fisheries in Peru for three species (i.e., M. birostris, Pristis pristis, Rhinoptera steindachneri) and two taxa (i.e., Mobula and Myliobatis) which are not fully enforced. Batoid research in Peru is limited, with only 25 publications from 1978 to 2022, in which the most studied species are Mobula birostris, M. chilensis and M. peruvianus. This study establishes an information baseline for batoids in Peru that can help guide their management, research, and conservation. \u0000 ","PeriodicalId":347046,"journal":{"name":"Revista de Biología Marina y Oceanografía","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114720219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding its parasitofauna, only two species of parasites have been registered and, given so little information, a parasitological study was carried out on 80 specimens of S. peruviana sampled from the coast of Tumbes, north of Peru, between June and October 2018. The ecological descriptors of parasitic infection/infestation, the degree of parasitic dispersal, the alpha diversity indices and the correlation the parasitological indices and biological characteristics of the fish (TL and sex) were calculated. Two species of monogeneans (Oaxacotyle oaxacensis and Metamicrocotyla macracantha), one species of trematode (Lecithocladium cristatum) and four species of copepods (Naobranchia sp., Lepeophtheirus sp., Caligus sp. and Lernanthropus sp.) were recorded. The monogenean O. oaxacensis was considered the only core species (e.g., with prevalence >45%). The distribution found for O. oaxacensis and L. cristatum was aggregated and there was no association between TL and sex with the parasitological indices. In the case of alpha diversity indices, the Margalef (Dmg), Shannon-Weaver (H´) and Pielou (J´) diversity index values were higher in females, but the Simpson dominance (D) did not show differences between the sexes. The diversity index of parasitic H' showed a higher value in the sizes over sexual maturity of S. peruviana. The parasitic D index presented an opposite pattern. All the parasite species found in this study are new records for S. peruviana and for Peru.","PeriodicalId":347046,"journal":{"name":"Revista de Biología Marina y Oceanografía","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124722866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Para evaluar el efecto de las mareas en la abundancia, distribución y actividad en las aves acuáticas se realizaron conteos mensuales a lo largo de un transecto paralelo al margen de la laguna Barra de Navidad, desde marzo 2011 a febrero 2012 (12 en marea alta y 12 en marea baja). El perímetro de la laguna fue dividido en cuatro zonas con la misma longitud; A, B, C y D. Se identificaron 52 y 7.775 registros en marea alta y 68 especies y 16.469 registros en marea baja. En marea alta predominaron las aves marinas (14 especies y 3.590 registros) y zancudas (15 especies y 2.075 registros), y en marea baja fueron las aves playeras (23 especies, 5.975 registros) y las aves zancudas (17 especies, 5.458 registros). La abundancia estacional exhibió patrones similares en todos los grupos de aves, con incrementos invernales (enero a marzo), excepto en los patos y especies afines (Podicipedidae y Rallidae). Los planos lodosos, al sureste de la laguna (zona C), concentraron la mayor abundancia de aves y fueron usados como área de alimentación durante la marea baja.

Se entrega un listado de sitios identificados como relevantes para esta especie, junto con detalles de los movimientos de las aves entre distintos humedales marinos y estuarinos de la Región. Se elaboró una base de datos espacial generada por siete transmisores satelitales instalados en individuos de L. haemastica. De estos, cinco fueron instalados en noviembre 2015 en el humedal marino de Chullec (42,47°S; 73,53°O), Chiloé. Mientras que los otros dos fueron instalados en noviembre 2020 en el humedal La Pasada (41,60°S; 73,59°O), Maullín. Los resultados indicaron que L. haemastica utiliza distintos humedales marinos y estuarinos de la Región de Los Lagos, tanto continentales como insulares. Estos movimientos mostraron un patrón de uso que permite proponer una red de sitios que conecta el paisaje continental e insular.
