“…Com vistas ao ordenamento das atividades/usos do espaço marinho da região Sul do Brasil, Gandra (2020) propõe uma abordagem para definição de unidades ambientais marinhas e áreas prioritárias para gestão. Destacam-se para a atividade de pesca, independentemente de sua modalidade, algumas pesquisas no contexto de PEM (Costa et al, 2018;Fonseca et al, 2017;Port et al, 2016;Rosso & Pezzuto, 2016); bem como, levantamentos e mapeamentos de fundo (Goes et al, 2019;Mattos et al, 2018;Gorman et al, 2017;Maia & De Alencar Castro (2015) e diagnósticos sobre a distribuição e ocorrência de espécies (Soeth et al, 2020;Pinheiro et al, 2019;Patrizzi & Dobrovolski (2018); Ramos et al, 2017;Cruz et al, 2015) que podem, posteriormente, orientar esforços de conservação e uso sustentável do espaço marinho brasileiro. Acrescenta-se ainda, estudos nacionais que orientam para a integração das mudanças climáticas no desenvolvimento do PEM (Patrizzi & Dobrovolski;Soares, 2018).…”

Coastal and marine spaces all around the world are committed to a current global sustainability agendas, in the seas and coasts, as well as their public policies and territorial governance agendas have received a special role in international discussions on the directions of development and conservation. In this context, the establishment of the Sustainable Development Agenda for 2030 (Agenda 2030) by the United Nations (UN) stands out which incorporated Objective 14, seeking to establish a science-political-society interface and strengthening the management of oceans and coastal zones for the benefit of humankind. In this scenario, in line with the global agendas and in order to identify and fill gaps in the interface between produced science and public policies for Brazilian marine-coastal environments, the initiative “Programa Horizonte Oceânico Brasileiro (HOB)” was created. The theme “Marine Space Planning (MSP)” is extremely relevant in the scope of the HOB, given its proposal for innovation through an ecosystem approach. Furthermore, MSP has been adopted as a mechanism for environmental policies in the international intergovernmental sector in countries with different levels of development, as a public policy and operational platform in planning and management of uses in the marine-coastal space. In this context, the activities of the Marine Space Planning Team (Team PEM) were established, which has been producing knowledge to strengthen the MSP in the path of collective inter-network learning and disseminating information that can assist future research, management and ordering actions in Brazilian seas and coasts, such as the publication of the.“I Volume Horizonte Oceânico Brasileiro” (Chapter 5 - Planejamento Espacial Marinho: Desafios e Oportunidades para Inserção Inter-Redes no Pré Planejamento Espacial Marinho Brasileiro) and the “Síntese para Tomadores de Decisão – I VOLUME HOB” (Planejamento Espacial Marinho: Desafios e Caminhos para sua Implementação) and the webinar of Marine Spatial Planning. This article aims to present the production of general knowledge about MSP by this group and its potential interaction with different systems (social, economic and political), looking to contribute and improving the information base of Brazilian coastal governance and also to subsidize possible initiatives related to the theme.

“…

Species-specific length-weight relationships (LWRs) are valuable in fisheries science because fish size is often measured in terms of body length (Froese et al, 2014). For example, fish length estimates from non-destructive sampling methods (e.g., underwater visual census and remote underwater videos) are converted into weight using LWRs to provide fish biomass estimates (Daros et al, 2018;Wilson and Graham, 2018;Soeth et al, 2020). Moreover, detailed information on LWRs and their uncertainties allows us to investigate fisheries and their environmental impacts (Lehodey et al, 2008;Philippsen et al, 2019), to estimate the regional and global active carbon flux of fish (Saba et al, 2021), to estimate trophic interactions (Machado et al, 2020), and to calculate body condition indices and This study encompasses the description and evaluation of the length-weight relationship of 104 demersal fish species caught by bottom trawlers targeting shrimps on the southeast continental shelf of Brazil from 2004 to 2006.

Species-specific length-weight relationships (LWRs) are valuable in fisheries science because fish size is often measured in terms of body length (Froese et al., 2014). For example, fish length estimates from non-destructive sampling methods (e.g., underwater visual census and remote underwater videos) are converted into weight using LWRs to provide fish biomass estimates (Daros et al., 2018;Wilson and Graham, 2018;Soeth et al., 2020). Moreover, detailed information on LWRs and their uncertainties allows us to investigate fisheries and their environmental impacts (Lehodey et al., 2008;Philippsen et al., 2019), to estimate the regional and global active carbon flux of fish (Saba et al., 2021), to estimate trophic interactions (Machado et al., 2020), and to calculate body condition indices and This study encompasses the description and evaluation of the length-weight relationship of 104 demersal fish species caught by bottom trawlers targeting shrimps on the southeast continental shelf of Brazil from 2004 to 2006. The regression criteria describing the length-weight relationship for each species were classified as approved (met the criteria), approved with reservations (partially met the criteria), and not approved (did not meet the criteria) based on linear regression parameters to determine whether length is a viable predictor of weight. A total of 141,433 individual fish, comprising 44 families and 104 species, were sampled; the beta parameter (± se) varied from 0.22 ± 0.12 to 3.94 ± 0.19, and the alpha parameter varied from -4.09 ± 0.04 to 0.89 ± 0.02. In total, 22 species were not identified by a recent large survey (2019) conducted in the study area. The results of this study are significant for the management of fishery resources, mainly due to the occurrence of unusual species, the economic importance and enormous effort exerted by the trawling fleet in the region, and the substantial sample size, in which a large number of individuals per species were caught.
