Item Relatório de Estágio Supervisionado Obrigatório - Laboratório de Aquicultura e Sustentabilidade e Base de Pesca(2025-02-27) Silva, Lucas Felix da; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086Item Uso de tampas plásticas como mídia filtrante alternativa em Aquacultura: primeiro protótipo de filtro(2024-10-01) Maranhão, Alberia Jacqueline Alves; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/0852093549676817Water use increases as aquaculture grows. The quality and quantity of water is essential for aquaculture, mainly fish farming and indoor shrimp farming (freshwater). Another requirement is the aspect of treated effluents in discharges into the environment. Therefore, the present work aims to test and design a sustainable filter model, using plastic covers as filter media. 10-liter water bottles (PET) were used, perforated on their sides, with around 200 PET bottle caps as filtering media, thus simulating a biological and mechanical filter. Aquarium pumps were introduced inside the bottles, creating a circulation of bubbles where the water is pushed upwards, and water to be filtered enters the bottle in a dynamic water circulation system. Bacteria that settle in the filter will reduce organic matter (nitrogenous nutrients), and the shape of each cap reduces the velocity of particulate matter within the filter, reducing turbidity, and concentrating this particulate organic matter, and other debris, within the filter. filter. This makes filters lighter and cheaper, replacing traditional media (such as those made with ceramic), and reducing the disposal of plastic lids in the environment, reusing this type of material. The experiment was conducted in three 20-liter tanks, supplied with water from fish farming effluents from the Continental Johei Koike Fish Farming Station, at UFFRPE. Physical and chemical data were evaluated every 3 days. The results indicate that there was stabilization of pH, where the water initially had a pH of 6 (on average), to 7. There was an improvement in transparency, and an improvement in the degradation of total ammonia and nitrite, key factors in water quality, aiming to improve the management conditions and productivity in aquaculture.Item Development of machine learning models for the prediction of dissolved oxygen in aquaculture 4.0(2021-02-24) Freitas, Fábio Alves de; Nóbrega, Obionor de Oliveira; Lins, Fernando Antonio Aires; http://lattes.cnpq.br/2475965771605110; http://lattes.cnpq.br/8576087238071129; http://lattes.cnpq.br/5725435192607619The world faces the problem of feeding a growing population, which will reach more than 9 billion people by 2050. Thus, there is a need to develop activities that promote food production, within the dimensions of sustainability (social, technicaleconomic, and environmental). In this context, IoT systems focused on aquaculture 4.0 stand out, which allows the cultivation of high productions per unit of volume, with low environmental impact. However, these systems need to be extremely controlled, requiring sensors to perform realtime readings of water metrics, with emphasis on the dissolved oxygen (DO) sensor, which plays an essential role in determining the quality and quantity of available habitat for the organisms present in the system. Even with this importance, this sensor is often not used, due to its high associated cost. As an alternative solution to this problem, machine learning models have been proposed to predict DO, using temperature and pH readings as inputs. Experiments were carried out comparing different data scaling techniques and the prediction performance in different seasons of the year and regression metrics were used to evaluate the implemented models. The results showed that the proposed LSTM model is capable of making OD predictions and being applied in IoT and aquaculture 4.0 systems.Item Aquicultura vai à escola parte II – uma extensão prática da aquicultura em Itapissuma-PE(2021-02-05) Santos Filho, Fernando Sebastião dos; Olivera Gálvez, Alfredo; Santos, Elizabeth Pereira dos; http://lattes.cnpq.br/5362345525199085; http://lattes.cnpq.br/7002327312102794; http://lattes.cnpq.br/1445666896933448Due to the stagnation of fishing activity in recent years, aquaculture has emerged as an alternative to supply the demand for fish worldwide; with this, this type of production of food and biotechnological products has been growing significantly to meet the needs of the entire world population. According to FAO, aquaculture is the culture under control of aquatic animals and plants. Among the branches of aquaculture, we have: Pisciculture (Fish cultivation), Malacoculture (Mollusk cultivation), Shrimp farming (Crustacean cultivation) and Algiculture (Algae cultivation). In this study, the extension worker, together with undergraduate and graduate students linked to the Department of Fisheries and Aquaculture at the Federal Rural University of Pernambuco, went to the high school reference school (EREM) Eurídice Cadaval in Itapissuma - PE in order to establish an exchange of learning with regard to aquaculture, publicizing the activities linked to the baccalaureate course in fisheries engineering, which is currently not widespread in society, in addition to the performance of this professional in the area related to the productive sectors of the Itapissuma region (fish, crustaceans , mollusks and algae). The work was carried out through dynamic, practical and theoretical classes, given to high school students. In these classes, social, cultural and environmental topics were approached from the highlight of the problems that surround the daily life of the community, thus helping in the development of these students as citizens, opinion makers and future professionals who can work with the community they live.Item Triploidia em organismos marinhos: uma análise bibliométrica(2022-06-02) Costa, Bruno Borba Santos Ferreira; Olivera Gálvez, Alfredo; http://lattes.cnpq.br/7002327312102794; http://lattes.cnpq.br/0090047327576200Triploidy can be defined as the presence of three complete sets of chromosomes in cells. The induction of this state can be performed in some animals as a method to obtain advantageous characteristics for aquaculture. The present study aims to provide a bibliometric analysis on research trends related to the use of triploidy in marine organisms. The analysis included scientific productions indexed to the Scopus and Web of Science databases, from 1984 to 2021. The compiled data was converted to the R-data reading format with the RStudio software along with the use of the Bibliometrix package. The analyzes were performed using the Biblioshiny tool. A total of 190 articles published among 78 different journals were obtained, with the participation of 619 authors and collaboration between different countries. For the period analyzed, there was an annual growth rate of publications of 7.36%. Canada, the United States and Norway were the countries with the highest number of publications. The most frequent topics were represented on a thematic map according to a ranking of centrality and density. Topics such as "growth", "survival", "sterility", "Atlantic salmon", and "Crassostrea gigas" were classified as basic themes, with great relevance for the structuring of the research field, but still in development. These data provide important information on trends in triploidy studies with marine organisms, contributing to future studies in this field of research.Item Análise genética na investigação de origem da tilápia (Oreochromis niloticus) em cultivos comerciais(2019-07-12) Silva, Gênison Carneiro; Coimbra, Maria Raquel Moura; http://lattes.cnpq.br/7669497233462075; http://lattes.cnpq.br/3679959470967021The development of genetically improved tilapia strains was an important step in world aquaculture, considering growth, reproduction, weight gain, fillet yield and greater rusticity of the selected individuals. Acquiring improved seeds is the first step to shortening production time, however, the fish farmer should provide adequate conditions and structure to achieve optimal maximum performance. In biphasic tilapiculture systems in excavated nurseries, it is common for the nursery phase to occur in a different location than the fattening phase. In this case study, one producer purchased improved fingerlings from a tilapia breeding company “A” and sent them to company “B” to conduct the nursery phase. However, when such the producer received the “B” tilapia juveniles and fattened them, they did not show the expected zootechnical performance. The objective of this study was to detect if the tilapia of "A" and "B" had the same genetic origin. Were used genetic markers such as microsatellites and mitochondrial DNA control region (D-loop). A total of 79 samples were collected, of which 40 were from “A” and 39 from “B”. The samples had their total DNA extracted and were genotyped for the UNH104, UNH106, UNH160 and UNH208 microsatellite markers. Then, the samples had the control region haplotypes identified by sequencing. The genetic diversity of microsatellites was analyzed to correctly attribute that the origin of "B" came from "A". The alignment and editing of the D-loop also revealed a haplotype network with equitable stakes of "A" and "B" confirming that the groups belonged to the GIFT lineage. The techniques used show that the different zootechnical performance should be associated with issues related to the adopted management and stocking density during the nursery phase.Item Relatório De Estágio Supervisionado Obrigatório(2019-07-01) Costa, Anderson Cristiano Ferreira; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/3708648078406018Item Relatório de Estágio Supervisionado Obrigatório(2019-07-01) Santana, Carolina Louise Nascimento de; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/3950204773665511Item Relatório de Estágio Supervisionado Obrigatório(2019-01-29) Castro, Amanda Lucy Ferraz de; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086Item Viabilidade da aquaponia urbana: pequenos espaços e a produção animal sustentável(2019-06-19) Machado, Eric; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086The present work is a qualitative extension of the studies begun in ESO (Mandatory Supervised Internship). The installation of another aquaponics system in a building located in Sossego street, located in the Boa Vista neighborhood, central region of Recife, where the Cultural Center Brazilian Germany (CCBA) operates, has enabled us to carry out a comparative analysis with systems that were (UFRPE) campus, as well as another system set up at the Professor Johei Koike (UFRPE) Aquaculture Station / Department of Fisheries and Aquaculture (DEPAQ), also on the campus of the Aquaculture and Sustainability Laboratory of the Department of Animal Science of the Federal Rural University of Pernambuco headquarters of (UFRPE). Some observation points followed the following variables and requirements such as: system assembly; necessary materials; water conditions (pH, temperature, dissolved oxygen, carbonate hardness, toxic ammonia, nitrite); conditions of light incidence; productivity; monitoring of the system in fish farming and plant cultivation; management of the aquaponic system, yield of final production (animal and plant biomass), emergence of pests and diseases for animals and plants, evaluate responses of both to the conditions found in each parameter, besides costs for such an undertaking. However, to make a general survey of all the data inherent to the project and to evaluate the viability of this project, it should be used in small spaces, with little supply or availability of natural resources, deficiency in organic food production and work. The work also has the purpose of generating technical knowledge that can be applied in society, especially in family agriculture, with small and medium-sized rural producers and in urban centers, constituting a possible source of organic food, besides the possibility to be an alternative income generation for many families inserted in rural areas, thus avoiding the increase of the rural exodus and the most important, helping to solve the great problem of hunger in the world, especially in the most needy regions such as the Brazilian Northeast. This experimental research was carried out under the cultivation methodology of the Nutrient Film Techinique (NFT), and until the last test performed, the above-mentioned parameters as system variables, were zeroed to those that are systemic such as toxic ammonia and nitrites, as expected, showing the efficiency of systems in symbiotic processes.
