The use of probiotics, prebiotics and synbiotics provides better growth rates, improves the innate immune system protection against several bacterial pathogens. species Aeromonas hydrophila causes high mortality rate production loss, provoking an antimicrobial overuse. This study aimed to prove capacity commercial probiotic DBA® (Bifidobacterium sp, Lactobacillus acidophilus Enterococcus faecium), MOS chitosan, combined as or not promote Nile tilapia performance, modulation A. hydrophila....
The aquaculture industry is in considerable increases. Optimization of husbandary conditions intensive are continuous interest. Probiotic was proved as promising factors to enhance fish production by remodeling intestinal microbial balance, boosting immune system and reducing antibiotic uses. efficient strategy probiotic uses their protection still making debate. intake tilpia fed with basal diet enriched (Enterococcus faecium) its response following a challenge pathogenic strain Aeromonas...
This study aimed to verify the possible positive effects of feeding commercial probiotic Bioplus 2BC® [Bacillus subtilis (1.6 × 1010 CFU/g) and Bacillus licheniformis CFU/g)] Nile tilapia on its growth performance, nutrient digestibility, gut microbiology, haematology (hematimetric index, erythrocyte, leucocyte thrombocyte counts) innate immunology (lysozyme, burst respiratory phagocyte activities). For this purpose, one in vivo assay was performed following a completely randomized design,...
Nile tilapia, Oreochromis niloticus, is one of the most cultivated fish species in Brazil. However, few studies evaluate how stunning methods affect meat quality this fish. This study evaluates both methods, iced water and CO2 narcosis, tilapia that was stored refrigerated ice (4°C) for up to 26 days. Tilapia stunned by narcosis showed less stress compared water, which evidenced higher ATP, better color as well, lightness (L*) lower redness (a*) values. After sensorial analysis, were...
Brazil is one of the world's leading producers Nile tilapia, Oreochromis niloticus. However, industry faces a major challenge in terms infectious diseases, as at least five new pathogens have been formally described last years. Aeromonas species are Gram-negative anaerobic bacteria that often fish causing Motile Septicemia (MAS). In late December 2022, an epidemic outbreak was reported farmed tilapia state São Paulo, Brazil, characterized by clinical signs and gross pathology suggestive MAS....
This work examines the economic advantages of probiotic use in diet Nile tilapia broodstock during reproductive period. For this purpose, Bacillus subtilis was applied as a feed additive. The experimental design completely randomized with three treatment groups: T0 control (without probiotic), T1 continuous intake, and T2 alternate intake at dose 0.50 g kg-1 (1010 CFU g-1) four replicates. reproduction assay, 118 females 48 males (proportion 4 males:9 females. hapa-1) (weight 527.65 ± 185.98...
Streptococcus agalactiae is an important bacterial pathogen in intensive Nile tilapia production, causing high mortality rates and great economic losses. This work aimed to evaluate the vaccination against S. fed with ration containing probiotic AQUA PHOTO® composed of Bacillus subtilis Lactobacillus plantarum, on immune response action gut microbiota. The experimental design was completely randomized five treatments (CON = control; ADJ adjuvant; PRO probiotic; VAC vaccine; + vaccine)...
This study evaluated the probiotic mannan oligosaccharide (MOS), and marine algae for Nile tilapia (Oreochromis niloticus) feeding. The parameters analyzed were fish-growth rate, hematological immunological parameters, intestinal microbiota. Also, fish submitted to experimental infection challenge with Aeromonas hydrophila evaluate immune response. juveniles (weight 8.86 ± 3.22 g) used in six treatments four replicates, 63 days. were: control basal diet; PAS-TR: diet plus 0.04 g·kg-1 of...
Electrical stunning is considered one of less stressful fish method. However, for its efficiency, it important to determine the best way application electrical variables. The aim this study was evaluate effect different voltages (100, 150, and 200 V) alternating current (AC) or direct (DC), frequency 50 Hz, 180 s exposure, concerning aspects behavior meat quality pacu (Piaractus mesopotamicus). Fish subjected AC remained unconscious longer, evaluated by analysis, when compared DC. 100 AC, DC...
This study aimed to evaluate the effect of CO2 narcosis (CN), hypothermia (HY) and electrical stunning (ES) on physiological stress meat quality chilled pacu. Pacus submitted ES took approximately 30 s unconsciousness, while those HY lost consciousness in 28 min CN 54 min. Higher catalase, lactate dehydrogenase glutathione reductase activity were observed ES. led an increase cortisol levels when compared CN. ATP found CN-exposed There was a decrease muscle pH (no difference between...
ABSTRACT: The inclusion of sesame oil associated with soybean, linseed and freshwater fish residue in the diets fed to Lambaris Astyanax altiparanaewas evaluated by growth performance parameters, body composition possible physiological changes (GARUTTI & BRISTSKI, 2000). experiment was a completely randomized design two factorial parameters tested: three types (soy (SO), (LO) (FRO)), combined or not (SEO), totalizing six treatments four replications 24 cages, capacity 0.70m3 (density 251...
The aim of this paper was to test isolated and pre-selected bacteria strains from Nile tilapia intestinal mucus, collected in Brazilian commercial fish farming, use as probiotics the feeding. variable were growth performance, hematology, microbiology immunology. These submitted vitro inhibition tests pathogenic bacteria. Then, they identified by PCR sequencing, comparing using BLAST software. experiment carried out Fisheries Institute, Sao Paulo, Brazil, for 84 days, following randomized...
The objective of this research was to evaluate the growth performance, oxidative stress, and fatty acid profiles lambari (Astyanax altiparanae) fed diets containing different lipid sources: soybean oil, linseed freshwater fish residue oil combined or otherwise with sesame (SEO). (mean weight 0.95±0.46 g; mean length 4.21±2.77 cm) were distributed into 24 cages (cage capacity: 0.70 m3; density: 276 individuals m−3) in six treatments four replicates. After 80 days feeding, they weighed,...
O objetivo do presente trabalho foi determinar o efeito de dietas com relações 18:3n3/18:2n6 de: 2,98; 1,68; 1,03; 0,61 e 0,35 (tratamentos 1 a 5 respectivamente) sobre coeficiente digestibilidade aparente (CDA) dos ácidos graxos em vegetais para juvenis pacu (Piaractus mesopotamicus). Dezoito grupos 16 peixes cada um foram alimentados por 34 dias dieta controle contendo óleo tilápia como único ingrediente origem animal (tratamento 6). Numa segunda fase, durante 72 dias, fornecida três...
