Item Obtenção e caracterização físico-química e nutricional de concentrado proteico oriundo de resíduos de filetagem de saramunete, Pseudupeneus maculatus (Bloch, 1793)(2024-06-06) Amaral, Rodrigo Pinheiro Crasto; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205; http://lattes.cnpq.br/5798261290131048The aim of the present study was to obtain and characterize the protein concentrate of saramunete filleting waste, Pseudupeneus maculatus. Two types of saramunete protein concentrate (CPS) were developed, type A and type B, which can be differentiated by color and odor, evaluating yield, pH, water activity, chromatic coordinates, volatile nitrogen bases, humidity, protein, fat and ash.. The type A saramunete protein concentrate showed lower yield, despite being more acidic (lower pH) and higher L* value (brightness), lower a* value (red/green) and higher b* value (yellow/blue) than CPS type B. The water activity, moisture percentage and volatile nitrogen bases of CPS were low and with no difference between treatments. CPS type A had a higher percentage of protein, indicating better protein quality. Furthermore, it presented a lower amount of lipids, indicating that it is less susceptible to lipid oxidation. Therefore, type A CPS is a good way to add value to saramunete waste as it presents a good CPS yield, appreciable physical-chemical characteristics and nutritional aspects compatible with other fish protein concentrates, having potential for use in food products.Item Composição da dieta de jovens de boca mole Larimus breviceps (Cuvier, 1830) (Actinopterygii: Sciaenidae) no litoral de Pernambuco(2022-05-26) Santos, Thamires Vieira dos; El-Deir, Ana Carla Asfora; Silva, Francisco Marcante Santana da; http://lattes.cnpq.br/4286692304867555; http://lattes.cnpq.br/4822569793807941; http://lattes.cnpq.br/3895003399617232The surf zones are important places for several species of fish, as they serve as shelter, protection and food. Knowledge the natural diet of fish allows us to infer about the availability of food, as well as reveal aspects of biology and their trophic relationships. Larimus breviceps belongs to the Sciaenidae family, being one of the most important species in artisanal fisheries. Thus, the present study aimed to know the diet of L. breviceps in the surf zone of Jaguaribe beach, north coast of Pernambuco. The collections were carried out during low tide, through beach trawls using a 20 m long, 1.5 m high and 5 mm mesh size net of the hose type between August 2020 and July 2021. The specimens collected were measured and eviscerated in the laboratory, then the stomachs were analyzed for the degree of repletion and the items identified to the smallest taxon possible. The diet was characterized based on the frequency of occurrence (FO %) between the rainy and dry months and periods. A total of 117 individuals ranged from 20,03mm-132.20mm in standard length. Of the total, 17 stomachs were empty 14.83% and 100 contained food. thirteen food items divided into 5 categories were identified (Crustacea, Teleostei, plant material, detritus and microplastic). The Crustacea category had the highest abundance with FO% 0.92 followed by Teleostei with 0.86. The same pattern was observed for the rainy season in relation to the dry season with 0.889 and 0.796 respectively. The Larimus breviceps species has a carnivorous diet composed of shrimp and fish, with a tendency to carcinophagy, where Crustacea was the most consumed category. In view of the results, it is important to study the feeding of the species L. breviceps, thus contributing to a greater knowledge, there is little information in the literature regarding the feeding of young of the species.Item Incidência de resíduos de pesca antes e durante a pandemia do COVID-19 no litoral norte de Pernambuco – Brasil(2021-12-10) Gomes, Gabriella Agnes de Oliveira Pester; Oliveira, Paulo Guilherme Vasconcelos de; Viana, Danielle de Lima; http://lattes.cnpq.br/5870460867763634; http://lattes.cnpq.br/5700488412022830; http://lattes.cnpq.br/0989776818751325Abandoned, Lost or otherwise discarded fishing gear (ALDFG), described in 2009, refers to equipment such as cables, nets and traps that continue with an active catching function without any monitoring. These devices have generated growing concern, as they are responsible for causing several negative environmental impacts, such as ghost fishing, responsible for the mortality of species present on the IUCN Red List of Threatened Species. In addition, ALDFG account for approximately 10% of marine litter. In 2019, with the start of the new Coronavirus pandemic (SARS-CoV-2), the use of beaches was prevented, interfering directly on the fishing activity. Given this scenario, the aim of this study was to analyze the influence of the social isolation on the fishing activity and the incidence of ALDFG in northern Pernambuco. As well as describing and characterizing the ALDFG found in the beach region and comparing their frequency among the analyzed beaches. The surveys were carried out in 2019 and 2020, in four beaches on the north coast of Pernambuco, one of which is located within the Acaú-Goiana Extractive Reserve. Active searches were carried out in the beach environment, by a group consisting of four people. Each pair walked the beach in the same cities, simultaneously, for an hour. The ALDFG were photographed and collected, in addition to being taken to the Fishing Oceanography Laboratory for quali-quantitative analysis. Additionally, observation per unit of effort (OPUE) and absolute and relative frequencies were calculated. Much of the collected material was grouped into bands of smaller length, weight, diameter and height, demonstrating the predominance of fragments. There was a significant decrease in the frequency of ALDFG after the period of prohibition of the use of the beaches, but the seasonal variation remained the same, indicating that the fishing activity in the north of the state was probably not completely interrupted. The cities showed a significant difference between them, probably due to differences in the use and management of space, demographic density, tourism and the presence of a fishermen community. Thus, measures are needed to promote greater awareness of the topic and prevent the formation of new ALDFG.Item A voz dos pescadores sobre políticas públicas para a pesca artesanal – Colônia Z1 em Pernambuco – séc. XXI(2023-09-22) Monteiro, Tiago de Sá; Leitão, Maria do Rosário de Fátima Andrade; http://lattes.cnpq.br/8086721690207482The objective of this study consists of a dialogue with fishermen from the Z-1 Fisherman's Colony, in Recife, about public policies for artisanal fishing. A Case Study, in which the contributions of government public policies in the field of artisanal fishing were mapped and identified in this institution in the 21st century. Data from interviews and bibliographical research on the topic show that government dialogue with the researched community is incipient.Item História de um legado: a pesca artesanal como patrimônio(2021-03-04) Targino, Gustavo Maia; Luna, Suely Cristina Albuquerque de; http://lattes.cnpq.br/4941715690112297Item Pescadores e pescadoras artesanais: impactos socioeconômicos e ambientais do desastre do petróleo em municípios costeiros da Bahia(2021-12-21) Giusti, Juliana Vieira de Melo; Frédou, Flávia Lucena; Ferreira, Beatriz Mesquita Pedrosa; http://lattes.cnpq.br/3994459073070495; http://lattes.cnpq.br/4779271407117528; http://lattes.cnpq.br/3625924633830411To assess the impact caused by the oil spill on artisanal fishing in the state of Bahia, a field research was structured a year later, as well as a quantitative research using the Joaquim Nabuco Foundation (Fundaj Foundation) database for the state of Bahia. Altogether 605 fishermen answered the quantitative research questionnaire belonging to ten different municipalities in Bahia and 40 fishermen were interviewed for qualitative research in three communities of Porto Seguro and Prado municipalites, in the Extractive Reserve of Corumbau-BA. From the qualitative and quantitative research, respectively, 34 / 85% fish as their main activity, and 55% and 51.5% have "Registro Geral da Pesca - RGP" (General Registrer of Fishworkers). In addition to the impact on the environment, 38 and 92.4% said that the oil caused damage to fishing areas, the financial loss was cited: 24 declared zero income in the first months and 16 people had a reduction between 50% and 70% of their income. and 86.4% had an average reduction in family income. Problems such as the difficulty in purchasing other components of basic food and the devaluation of fish, with values taking more than a half year to return to market prices, were mentioned. In addition, during the pandemic period, the demand for fish suffered, resulting in a further decrease in price. Right after the disaster, the pandemic led to disarticulation, as many fishermen do not have remote access conditions. The resistance of traditional and environmental peoples was observed. Despite the sequence of impacts, they continued fishing, which should not be a justification for the lack of responsibility and compensatory actions. Health damage needs to be investigated. In addition, environmental and fish health monitoring needs to be carried out on an ongoing basis. It is necessary to listen to the communities, reinforce digital inclusion to facilitate meetings remotely in the pandemic, aiming to resume the articulations that strengthen the management of territories in a participatory and efficient manner.Item Relatório do Estágio Supervisionado Obrigatório realizado na Associação de Pescadores e Trabalhadores em Atividades Afins de Igarassu(2019-02-05) Duarte Filho, Pedro Paulo; Oliveira, Paulo Guilherme Vasconcelos de; http://lattes.cnpq.br/5700488412022830Item Composição e variação temporal da assembleia de peixes capturados em currais no litoral norte do estado de Pernambuco(2019-01-23) Dias, Victor Sacramento; Andrade, Humber Agrelli de; http://lattes.cnpq.br/5938373350418153; http://lattes.cnpq.br/9813030378070984
