Fish diets should not only be formulated to meet nutritional needs (e.g., protein and energy), but also prevent disease promote health. In this regard, essential oils addition of fish commercial interest has been intensifying in recent years. This 45-day study assessed the efficacy dietary supplementation with oil Melaleuca alternifolia (EOMA) improving growth survival tambatinga (Colossoma macropomum x Piaractus brachypomus) naturally infected Saprolegnia sp. The juveniles (10.60 ± 2.18 g;...
ABSTRACT The aim of this study was to evaluate if Lippia alba has different chemotypes according the chemical composition essential oil (EO) considering collection site, and EO may have effects on blood plasma parameters in silver catfish, Rhamdia quelen, during immediately after anesthesia. citral (EO-C) linalool (EO-L) were identified, both presented similar anesthetic for catfish. Fish exposed two concentrations each EO, which induced slow fast anesthesia (100 300 µL L-1, respectively)....
Experiments were performed to assess the afferent and efferent limbs of hypoxia-mediated humoral adrenergic stress response in selected hypoxia-tolerant tropical fishes that routinely experience environmental O(2) depletion. Plasma catecholamine (Cat) levels blood respiratory status measured during acute aquatic hypoxia [water Po(2) (Pw(O(2))) = 10-60 mmHg] three teleost species, obligate water breathers Hoplias malabaricus (traira) Piaractus mesopotamicus (pacu) facultative air breather...
The effects of dietary supplementation graded level (0, 0.25, 0.5, 1.0, and 2.0 ml/kg diet) Citrus aurantium essential oil (EOCA) on the growth, metabolic, oxidative parameters silver catfish (Rhamdia quelen) were investigated in a 60-day growth trial. Fish fed with ml EOCA per kg exhibited significantly better performance than those control diet. Glucose, lactate, protein levels liver muscle altered by addition EOCA. Hepatic lipid peroxidation levels, measured using thiobarbituric acid...
The effects of dietary supplementation with Citrus × latifolia essential oil (EOCL: 0, 0.25, 0.5, 1.0 and 2.0 ml EOCL/kg diet) on growth, survival, gut tract morphology the metabolic oxidative parameters tambaqui (Colossoma macropomum) were investigated in a 60-day experiment. inclusion up to diet did not promote growth; however, fish fed EOCL/ kg presented higher survival all EOCL groups had increased intestinal fold height length compared control group. After 60 days experiment, glucose,...
The aim of this study was to investigate the effects dietary Citrus x aurantium essential oil (EOCA) on growth and intestinal histomorphology silver catfish (Rhamdia quelen) fingerlings. Five diets with different doses EOCA (0.0, 0.25, 0.5, 1.0, 2.0 mL/kg diet) were evaluated. At end 60 days, performance positively correlated supplementation. results showed an increase in fold height middle intestine (MI) fish fed diet compared control group. In anterior (AI), enterocyte increased, while...
In a quantitative field research, the objective of this work was to determine best stocking density for tambatinga juveniles (Colossoma macropomum × Piaractus brachypomus) in recirculation system during 50 days cultivation. Tambatinga (0.72±0.02 g) were distributed 0.08 m3 polyethylene boxes with densities 5, 10 and 15 fish/box, five replicates per treatment. During experimental period, water quality, weight gain, apparent feed conversion, specific growth rate, carcass yield, proximate...
ABSTRACT The study developed a sensory scheme based on the Quality Index (QI) and estimated shelf-life for whole tambaqui, Colossoma macropomum (Cuvier, 1818), stored in ice, assessing determining most appropriate chemical, physical, bacteriological quality parameters their changes during storage time. Ninety six fish were evaluated at 1, 3, 5, 8, 10, 12, 15, 17, 19 22 days of ice-storage. index showed four main attributes with total 29 demerit scores. skin mucus odor, as well general...
A aquaponia é uma modalidade de produção alimentos que integra a aquicultura e hidroponia num sistema fechado recirculação água nutrientes. Esta atividade alternativa viável para sustentável onde o abastecimento mínimo, tornando seu uso mais eficiente por pequenos produtores ou em regiões com déficit da água. Este estudo avaliou crescimento do tambaqui (Colossoma macropomum) associado à durante um período 110 dias, quanto ao ganho peso, conversão alimentar sobrevivência dos peixes, os quais...
ABSTRACT Lippia grata (formerly known as gracillis) is an aromatic plant native to Brazil, with leaves rich in essential oils that possess significant biological activities. We evaluated the effect of oil L. (EOLG) a dietary additive on growth, somatic indices, and biochemical parameters juveniles (5.25 ± 0.26 g) tambatinga, hybrid fish obtained by crossing tambaqui (Colossoma macropomum) pirapitinga (Piaractus brachypomum) great economic importance north northeastern Brazil. four...
Resumo A busca por alimentos mais seguros levou a uma maior atenção da pesquisa para encontrar alternativas naturais aos aditivos sintéticos usados na indústria alimentícia. Os conservantes naturais, como os óleos essenciais (OE) de plantas, podem aumentar conservação dos peixes e até afetar positivamente saúde humana. Portanto, o objetivo do estudo foi avaliar efeito OE Mentha piperita nas características físico-químicas concentração microrganismos em carne resfriada tambatinga (Colossoma...
Abstract The search for safer foods has led to increased research attention discover natural alternatives synthetic additives that are used in the food industry. Natural preservatives, such as essential oils (EOs) from plants, could increase fish conservation and even positively affect human health. Therefore, objective of study was evaluate effect Mentha piperita EO on physicochemical characteristics concentration microorganisms chilled tambatinga (Colossoma macropomum × Piaractus...
O objetivo foi avaliar os efeitos de diferentes concentrações amônia não ionizada (zero; 0,15; 0,30; 0,50; 1,00 mg L-1 NH3) na histologia e morfologia das brí¢nquias fígado juvenis Bryconops caudomaculatus. Após 96 horas exposição, peixes foram anestesiados submetidos í necropsia para coleta fígado, que incluídos em parafina. Alterações morfológicas nas lamelas secundárias observadas a partir 0,15 L-1, como hiperplasia, hipertrofia, deslocamento epitelial, fusão lamelar, edema,...
Este estudo objetivou caracterizar as pisciculturas no município de Araioses/MA, visando subsidiar estratégias para o desenvolvimento da atividade na região.

This study investigated the possible antinutritional effects of Parkia platycephala lectin (0, 20, 40, or 60 mg kg-1 diet) on tambatinga feeding for days as well methods inactivating this protein. Weight gain, specific growth rate, and relative weight gain decreased, feed conversion rate increased with increase in dietary lectin. The hepatic glycogen levels fish fed were higher than those 20 40 kg-1. Diets containing muscle glucose compared to control group. Fish-fed diets showed reduced...
