Avaliação da solubilidade protéica e do teor de aminas biogênicas em atrativos ...
Castro, Otávio S.; Lemos, Daniel; Nunes, Alberto Jorge Pinto; Sá, Marcelo V.C; Oliveira, Gabriela: Nine commercial attractants for Litopenaeus vannamei feeds, tested by behavioral responses in Y-maze aquarium apparatus, were evaluated by crude protein level (CP), soluble protein level (SP) and biogenic amines amount: cadaverine (Cad), putrescina (Put) and histamine (Hist). Significant differences among the more efficient attractants against the worst ones were searched; broken line analysis and ANOVA were ...
Editorial
Rocha-Barreira, Cristina de Almeida; Nunes, Alberto Jorge PintoEm meio a tantas aflições em função da pandemia de covid-19, que já se arrasta há quase 2 anos e que nos levou familiares, amigos e conhecidos próximos e distantes, finalizamos em 2021 com sentimento de tristeza, alívio e muita esperança. Aos poucos, estamos retomando uma rotina diferente, com rostos cobertos e menos proximidade, mas estamos retornando. Os corredores do Instituto do Ciências do Mar (Labomar/UFC...
Growth of juveniles of the fat snook, Centropomus parallelus, in response to di...
Pinto, Ricardo Camurça Correia; Nunes, Alberto Jorge PintoThis study evaluated the growth of fat snook Centropomus parallelus in response to the dietary total lipids, gross energy (GE) and crude protein (CP) content. In the 1st experiment, five isonitrogenous diets with 541.7 ± 2.4 g kg-1 CP varied their lipid content in 113, 151, 160, 189 and 200 g kg-1 and GE in 18.8, 19.4, 20.4, 21.2 and 22.2 MJ kg-1, respectively. A total of 300 fish with 6.5 ± 2.4 g were stocked ...
Long-term impact of a 4-day feed restriction at the protozoea stage on metaboli...
Lage, Luis Paulo A.; Weissman, Delphine; Serusier, Mélanie; Putrino, Soraia Marques; Baron, Frederic; Guyonvarch, Alain; Tournat, MathieuBased on the ‘‘nutritional programming’’ concept, we evaluated the long-term effects of an early four-day caloric restriction (40% reduction in feed allowance compared to a normal feeding level) at the protozoea stage in whiteleg shrimp. We analyzed long term programming of shrimp by studying metabolism at the molecular level, through RT-qPCR of key biomarkers (involved in intermediary metabolism and digestion)...
Utilization of rice byproducts as carbon sources in high-density culture of the...
Leite, Jordana Sampaio; Melo, Caio Servulo Batista; Nunes, Alberto Jorge PintoThis study was conducted to evaluate the effect of rice byproducts on water quality, microbial community, and growth performance of L. vannamei juveniles. Shrimp of 0.98±0.10 g body weight (BW) were reared in 49 tanks of 1.5 m3 under 127 animals m−2 for 77 days. Rice bran, rice grits, and rice hulls were mixed into five different fertilizers varying their fiber content (90, 110, 150, 200, and 250 g kg−1) and co...
Produção de bioflocos em sistema de lodos ativados tratando efluente de carcini...
Santaella, Sandra Tédde; Vale, Maria do Socorro; Almeida, Clara Cabral; Cavalcante, Willame de Araújo; Nunes, Alberto Jorge PintoThe release of wastewater and the shrimp feed cost are the main challenges faced by the shrimp farming industry. An alternative solution to both problems is biofloc production in a unit external to the farm, in an activated sludge system for effluent treatment. The treatment system’s influent was composed of the shrimp farm wastewater supplemented with urea and sugarcane molasses. The results show that the aver...
Effect of dietary amino acid composition from proteins alternative to fishmeal ...
Silvão, Cristiane Freire; Nunes, Alberto Jorge PintoThis study investigated the effect of dietary amino acid composition from proteins alternative to fishmeal on the growth performance of the common snook, Centropomus undecimalis. Fish of 10.79±0.71 g (n = 150) were stocked in 15 shaded outdoor tanks of 1 m3 . The basal diet contained 643.4 g kg−1 salmon byproduct meal (SML) and 200.0 g kg−1 soy protein concentrate (SPC). Two other diets replaced 39 and 29% of t...
Performance and immunological resistance of Litopenaeus vannamei fed a β-1,3/1,...
Sabry Neto, Hassan; Nunes, Alberto Jorge PintoThis study determined the efficacy of a β-1,3/1,6-glucan source on the survival, growth, and immunological responses of Litopenaeus vannamei challenged with infectious myonecrosis virus (IMNV). The work was conducted in 20 tanks of 500 L with clear water with constant recirculation and aeration. Shrimp weighing 2.6±0.4 g were stocked at 100 animals/m2 and reared for 10 weeks. Viral challenge occurred through or...
Biodisponibilidade de proteína bruta e lipídio de refeições biofloc produzidas ...
Sabry Neto, Hassan; Santaella, Sandra Tédde; Nunes, Alberto Jorge PintoThe present study compared the bioavailability of crude protein and lipid from biofloc meals generated with an activated sludge system using two water sources: wastewater from shrimp experimental culture (BFL-W) and, artificially, using clean seawater (BFL-C). The sludge system operated by chemical and organic fertilization three times per week. Sampling of bioflocs occurred every two days during 81 days. To ev...
Dados de produção e qualidade de água de um cultivo comercial semi-intensivo do...
Nunes, Alberto Jorge Pinto; Sandoval, Patrício Fernando ChavezO presente estudo foi realizado em uma fazenda de cultivo comercial de camarão marinho localizada em Arez, Estado do Rio Grande do Norte, durante o período de outubro de 1995 a junho de 1996. O trabalho teve como objetivo relatar dados de produção e qualidade de água de dois cicIos de cultivo semi-intensivo dos camarões Penaeus subtilis e P. vannamei alimentados com ração comercial peletizada utilizando bandeja...
