“…Na década de 1990 a espécie de camarão de água salgada Litopenaeus vannamei (BOONE, 1931) foi introduzida no Equador e durante esses últimos 20 anos, devido a sua rentabilidade e altos índices de produtividade, fez esta atividade expandir no Brasil de forma acelerada, tornando o país o terceiro maior produtor de camarão em cativeiro da América Latina (Natori et al, 2011;Tahim, Damaceno e Araújo, 2019).…”

O objetivo desta pesquisa foi realizar a compartimentação das unidades de paisagens das planícies costeiras do litoral oriental do estado do Rio Grande do Norte, no táxon de geofácies em escala de 1:50.000. Para seu desenvolvimento foi utilizado o método abdutivo, através da Inferência à Melhor Explicação (IME), identificando as unidades a partir da sua fisionomia, de critérios naturais (geomorfologia, geologia, vegetação) e antrópicos (uso e ocupação), através da análise integrada das paisagens, seguindo a classificação dos táxons proposta pela escola francesa. No mapeamento, as imagens dos satélites usadas foram do Sentinel – 2A e 2B, oriundas do Serviço Geológico dos Estados Unidos. Foram mapeadas 21 geofácies, localizadas em dois geocomplexos diferentes, as Planícies Costeiras do Agreste Potiguar onde foram identificadas dez unidades de paisagem, com a de maior expressão espacial sendo a vegetação arbustiva em paleodunas ocupando 48% da área deste geocomplexo. Já nas Planícies Costeiras Úmidas, onze unidades foram mapeadas, sendo a unidade de maior área identificada a vegetação arbórea em paleodunas ocupando 25% das mesmas. Por fim, a pesquisa fornece uma base de dados atual de conhecimento territorial, gerando dados em escala de semidetalhe.Palavras-chave: uso e ocupação do solo, geossistema, sistema de informações geográficas - SIG, método abdutivo. Landscape units of the coastal plains of the eastern coast of Rio Grande do Norte, Northeast - Brazil A B S T R A C TThe objective of this research was to carry out the compartmentalization of landscape units of the coastal plains of the eastern coast of the state of Rio Grande do Norte, in the geofacies taxon at a scale of 1:50,000. For its development, the abductive method was used, through Inference to the Best Explanation, identifying the units based on their physiognomy, natural (geomorphology, geology, vegetation) and anthropic criteria (use and occupation), through integrated analysis. of landscapes, following the classification of taxons proposed by the French school. In the mapping, the satellite images used were from Sentinel – 2A and 2B, from the US Geological Survey. Twenty-one geofacies were mapped, located in two different geocomplexes, the Coastal Plains of Agreste Potiguar, where ten landscape units were identified, with the highest spatial expression being the shrubby vegetation in paleodunes occupying 48% of the area of this geocomplex. In the Wet Coastal Plains, eleven units were mapped, and the unit with the largest area identified was arboreal vegetation in paleodunes, occupying 25% of them. Finally, the research provides a current database of territorial knowledge, generating semi-detail scale data.Keywords: land use and occupation, geosystem, geographic information system - GIS, abductive method.

“…Semi‐intensive and intensive systems are mostly used in large and medium‐sized companies, where there are changes in the production processes ranging from the use of balanced feed with better consumption adjustment, correction and treatment of the nursery soil, controls of water physicochemical parameters and concern with wastewater treatment—oriented towards environmental sustainability (Borba & Nogueira, 2013; Rocha, 2006). A trend that is observed, however, is the emergence of the extensive system, suitable for the production of organic shrimp that has been expanding in the region (Tahim, Damaceno, & Araújo, 2019). These technological advances are especially noticeable in large and medium‐sized production companies and laboratories.…”

“…These technological advances are especially noticeable in large and medium‐sized production companies and laboratories. Small companies, although they are the majority, operate almost in an artisanal manner, using an easily adaptable technological package (Tahim et al., 2019). There are already farms adopting the organic production, the polyculture (intercropping of tilapia and shrimp) and in the process of implementing a system of traceability of crops, as well as the implementation of biofloc system (Tahim et al., 2019).…”

“…Other large input industries (feed, nitrogen and phosphate fertilizers, probiotics, etc.) and equipment (generators, pumps, motors, physical–chemical parameter metres, water and other inputs/equipment that are part of the shrimp process), distribution, packaging and other services are connected to this sector (Tahim et al., 2019). The production systems and scales of Brazilian marine shrimp farming ( L. vannamei ) apply different technologies depending on the size of the properties and the type of production.…”

The paper provides a short overview of Brazilian aquaculture production and some of the influences affecting its development. Data on total and species‐specific production are provided along with the locations, numbers of producers, their market contributions and influences. The focus is on some of the key groups, not all, especially tilapia, tambaqui, shrimp, prawn and mollusc farming. The wider influences on production including markets, management practices, technology, resources and research and also consumer and global influences are briefly mentioned to locate the developments in a wider context.

“…Os empreendimentos de carcinicultura têm sido um dos principais responsáveis pela deterioração dos manguezais, sobretudo, no Nordeste brasileiro (Mesquita et al, 2012;Ribeiro et al, 2014). A devastação dos manguezais pelas atividades de carcinicultura causa impactos significativos e de grandes dimensões, além de extinguir os manguezais, afeta diretamente a produção pesqueira, modificando as atividades econômicas tradicionais das comunidades costeiras (Lessa, 2007;Tahim et al, 2019).…”

The article aimed to carry out a multitemporal mapping to show the expansion of shrimp farming in the communities of São Francisco and Barra dos Carvalhos, in the municipality of Nilo Peçanha (BA), from the records available in the free tool of Google Earth Pro. The mangrove is of paramount importance for countless estuarine and marine species that use the mangrove environments for shelter, food and refuge, as well as for sustaining fishing and shellfish carried out by artisanal fisheries communities and their food security. High-resolution images were selected for the years 2002, 2012 and 2017. The methodological approach was based on the visual analysis of the images, to identify the classes of use and coverage and the main vectors responsible for the suppression of mangrove areas. To support vectorization, an identification key was developed based on the principles of photointerpretation. Field outings were performed to collect data with the GPS receiver to validate the mapping. In the three years analyzed, it was possible to notice that there was a significant advance in the shrimp farming class. Between 2012 and 2017 there was a significant increase in the number of shrimp farming tanks, now occupying an area of 1.0 km2, an increase of 0.80 km2, corresponding to an area of occupation 5 times greater (500% expansion) than that observed in 2002.
