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.
