Resumo: | Ucides cordatus (Linnaeus, 1763), the uçá crab, is a subsistence resource for the communities surrounding the mangroves of the RDS Municipal Piraquê-açú and Piraquê-mirim (ES, Brazil). In order to subsidize the management of this resource, population and commercial density (extractive potential), the average size of the crabs, the sex ratio, as well as the percentage of open and closed galleries in the post-closed period were estimated in 18 plots of 100m² along the Estuarine System. The population density found was 0.74 ± 0.24 ind./m² and the commercial 0.10 ± 0.05 ind./m², which may indicate continuous exploration of the species in the region. The sex ratio was 2: 3, with carapace width (LC) for males from 55.77 to 80.38 mm and mean of 67.12 ± 6.50 mm, and females from 25.34 to 74.94 mm and a mean of 61.60 ± 11.40 mm, values close to those found in previous studies in the RDS. The similarities regarding the environmental conditions in which the uçá crab populations are found throughout SEPAPM demonstrate the potential for monitoring the species, so management strategies are proposed in order to assist the management of this fishing resource in the Municipal Reserve. |

Para subsidiar el manejo de este recurso, se estimó la densidad poblacional y comercial (potencial extractivo) en 18 parcelas el tamaño promedio de los cangrejos, la proporción de sexos, así como el porcentaje de galerías abiertas y cerradas en el período post-cerrado. de 100m² a lo largo del Sistema Estuarino. La densidad poblacional encontrada fue de 0,74 ± 0,24 ind./ m² y la comercial de 0,10 ± 0,05 ind./m², lo que puede indicar exploración continua de la especie en la región. La proporción de sexos fue de 2: 3, con ancho de caparazón (LC) para machos de 55,77 a 80,38 mm y media de 67,12 ± 6,50 mm, y hembras de 25,34 a 74,94 mm y una media de 61,60 ± 11,40 mm, valores cercanos a los encontrados en estudios previos en RDS. Las similitudes en cuanto a las condiciones ambientales en las que se encuentran poblaciones de cangrejo uçá a lo largo de la SEPAPM demuestran el potencial de monitoreo de la especie, por lo que se proponen estrategias de manejo para ayudar al manejo de este recurso pesquero la Reserva Municipal.Ucides cordatus (Linnaeus, 1763), o caranguejo-uçá, é um recurso de subsistência as comunidades do entorno dos manguezais da RDS Municipal Piraquê-açú e Piraquê-mirim (ES, Brasil). Com o objetivo de subsidiar a gestão deste recurso foi estimada a densidade populacional e comercial (potencial extrativo), o tamanho médio dos caranguejos, a razão sexual, bem como a porcentagem de galerias abertas e fechadas, no período pós-defeso, em 18 parcelas de 100m² ao longo do Sistema Estuarino. A densidade populacional encontrada foi 0,74 ± 0,24 ind./ m² e a comercial 0,10 ± 0,05 ind./m² podendo indicar contínua exploração da espécie na região. A razão sexual foi de 2:3, com largura de carapaça (LC) para machos de 55,77 a 80,38 mm e média de 67,12 ± 6,50 mm, e fêmeas de 25,34 a 74,94 mm e média de 61,60 ± 11,40 mm, valores próximos aos encontrados em estudos anteriores na RDS. As similaridades quanto às condições ambientais em que as populações de caranguejo-uçá se encontram ao longo do SEPAPM demonstram o potencial existente para o monitoramento da espécie, por isso são propostas estratégias de manejo a fim de auxiliar a gestão deste recurso pesqueiro na RDS Municipal.Research, Society and Development2020-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1099210.33448/rsd-v9i12.10992Research, Society and Development; Vol. 9 No. 12; e25791210992Research, Society and Development; Vol. 9 Núm. 12; e25791210992Research, Society and Development; v. 9 n. 12; e257912109922525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/10992/9889Copyright (c) 2020 Vanessa Cusini Spinassé Bromenschenkel; Mônica Maria Pereira Tognellahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Bromenschenkel, Vanessa Cusini SpinasséTognella, Mônica Maria Pereira2020-12-30T23:32:22Zoai:ojs.pkp.sfu.ca:article/10992Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:55.900973Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
