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 Biologia reprodutiva de Neocallichirus maryae Karasawa, 2004 (Crustacea, Decapoda, Callichiridae) na praia de Mangue Seco, Igarassu, Pernambuco, Brasil(2020-01-27) Matoso, Marcos Antonio Lima; Carvalho, Mônica Lúcia Botter; Costa, Larissa Bacelar da; http://lattes.cnpq.br/6227388035808608; http://lattes.cnpq.br/1762304533046987; http://lattes.cnpq.br/4408208899837080The present work aims to study the reproductive biology of the ghost shrimp Neocallichirus maryae Karasawa, 2004, on the Mangue Seco beach, north coast of Pernambuco. Thus, intending to contribute with unprecedented information to fill this gap. Collections were carried out, monthly, at Mangue Seco beach during low tide, between September 2018 and October 2019. The females were collected using a manual suction pump and sieves. In the laboratory, the abundance of ovigerous females (OF) in relation to non-ovigerous females, the length of the cephalothorax (CF), size of sexual maturation, reproductive period, embryonic development stage, fecundity, egg volume and reproductive effort (RE) were analyzed. A total of 358 females were collected, 48 OF and 301 non-ovigerous females. The CF of non-ovigerous females ranged from 5.98 mm to 17.97 mm with an average of 13 mm (± 1.976), however for OF the measures ranged from 9.37 mm to 16.48 mm with 13.34 (± 1.970); defining the size of the sexual maturity as the FC measurements between 9mm and 9.5mm. The occurrence of reproductive period was observed during the dry season (between December / 2018 to March / 2019), which is expected as a standard for decapods. The 3 stages of embryonic development were found during the reproductive period. Fertility ranged from 1057 to 3784, with an average of 2001.4 ± 815.04. The number of eggs increased significantly following the size of the females. The average egg volume was 0.157 mm³ (± 0.021) for stage I, 0.091mm³ (± 0.038) for stage II and 0.065 mm³ (± 0.026) for stage III. The average ER was 0.0601 ± 0.241. With dry weight of the egg mass representing only 0.78% of the dry weight of the females. The aspects about reproductive biology studied for the population of N. maryae follow similar patterns to the other studies done for the group of ghost shrimp worldwide. Finally, this study brings new information about Neocallichirus maryae, filling in some gaps and enabling future research on the species.Item Relato de experiência: beneficiamento de camarão na indústria de pescado(2022-10-14) Santos, Daniela de Souza Simões; Rolim, Maria Betânia de Queiroz; http://lattes.cnpq.br/5676854885081836The Estágio Supervisionado Obrigatório (ESO) discipline has 420 hours, and is a component of the mandatory curriculum for the eleventh period of the Bachelor's Degree in Veterinary Medicine at the Universidade Federal Rural de Pernambuco.

In Brazil, the species leads the national shrimp farming earning about R$1.6 million. Seeking to optimize cultures, new methods of physiological regulation can generate important results. The investigation of the modulation of the action of enzymes in the endocrine/digestive systems is an alternative with the potential to obtain significant results. Recently, it was proposed that the enzyme butyrylcholinesterase (BChE) plays a role in the metabolism of ghrelin, known as the “hunger hormone” and may influence feed intake and productive performance. The present study aimed to investigate the in vitro effect of BChE inhibitors as a physiological tool using food additives and their application in marine shrimp diets. Juveniles of L. vannamei in the fattening phase (2g, 4g and 6g) were obtained from a local producer and enzyme activity tests were carried out in different tissues (eye, muscle and hepatopancreas) using the IC50 parameter (concentration that inhibits the enzymatic activity by 50%). Tests were carried out to evaluate the inhibitory effect of the following plants: arugula (Eruca sativa), Swiss chard (Beta vulgaris) and spinach (Spinacea oleracea). The best inhibition results were arugula IC50: 0.019μg/mL in 6g shrimp; chard IC50: 0.14μg/mL in 4g shrimp and spinach IC50: 0.20μg/mL in 4g shrimp, chard showed better results for use as an additive. The feed was processed, and inhibitor extracts were added to the feed, in different samples, using grain alcohol as an incorporating vehicle. The physical and bromatological evaluations were then conducted, in the physical tests the repelletized rations showed a difference only in apparent density, even the repelletized rations being denser the buoyancy was not affected, for the bromatological tests they only showed lower humidity, due to the time in the oven. It can be concluded that individuals of average weight (4 g) have greater BChE activity, suggesting that this phase is ideal for introducing feeds with BChE inhibitors and that the inclusion of additives in shrimp feed, using the repellent method, can be used without impairing the nutritional and physical quality of the feed.Item Salinização da água e seus efeitos sobre o desempenho zootécnico do camarão marinho Penaeus vannamei na fase de berçário(2023-01-24) Cavalcanti, Bruno Roberto de Siqueira; Silva, Luis Otávio Brito da; http://lattes.cnpq.br/3365265235618078; http://lattes.cnpq.br/4106106458669767Item Efeito da frequência de adição do zooplâncton Brachionus plicatilis sobre o desempenho zootécnico de pós-larvas da espécie Litopenaeus vannamei cultivado em sistema de bioflocos(2023-03-15) Malandra, Adely Leticia Alves; Silva, Luis Otávio Brito da; http://lattes.cnpq.br/3365265235618078; http://lattes.cnpq.br/5263002170389598
