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 Avaliação da digestibilidade de farinha de cefalotórax de camarão (Penaeus vannamei) em dietas para tilápia (Oreochromis niloticus)(2023-09-22) Campelo, Kesya Leal; Santos, Juliana Ferreira dos; http://lattes.cnpq.br/6621907859216486; http://lattes.cnpq.br/2587814165212462In order to promote knowledge about alternative ingredients for aquatic animal feed formulations, the apparent digestibility coefficients (ADC) of protein, dry matter and crude energy of two ingredients in tilapia feed were determined. Seventy-two juvenile Nile tilapia (Oreochromis niloticus) with an average weight of 61.85±10.06 g were used in a completely randomized experimental design with three treatments, three replications and eight fish per box, alternating between the box and the hatchery. Three treatments were used: Reference feed, based on the nutritional needs of the species; Test feed consisting of the reference feed with the addition of shrimp cephalothorax meal (P. vannamei) whole with reference feed; Test feed consisting of the reference feed with the addition of shrimp cephalothorax meal (P. vannamei) with low fat content. The ADC was determined by the indirect method using 1% celite as an inert indicator. The CDA for crude protein was 94.14% and 94.22% and digestible values for crude protein were 51.96% and 56.90%; for dry matter, 92% and 91.8%; for energy, 92%; and digestible values of 80 and 89% were found. Shrimp cephalothorax waste was considered a potential substitute for protein in feed for the species.Item Piscicultura marinha: acompanhamento do desenvolvimento do Beijupirá (Rachycentron canadum) até a completa adaptação a ração comercial(2019-09-16) Andrade, Daniel Gregório Lima de; Oliveira, Paulo Guilherme Vasconcelos de; http://lattes.cnpq.br/5700488412022830; http://lattes.cnpq.br/0048892290455246Item 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) Lira, Patricia Monteiro de; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086Item Relatório de Estágio Supervisionado Obrigatório(2019-01-29) Castro, Amanda Lucy Ferraz de; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086Item Hábito alimentar da espécie Pseudupeneus maculatus, Bloch, 1793, capturada no nordeste brasileiro(2018-08-13) Barbosa, Édipo Lucas Soares; Frédou, Thierry; http://lattes.cnpq.br/8119220407894290; http://lattes.cnpq.br/0107690460253805
