Muscle growth mechanisms are controlled by molecular pathways that can be affected fasting and refeeding. In this study, we hypothesized short period of followed refeeding would change the expression muscle growth-related genes in juvenile Nile tilapia (Oreochromis niloticus). The aim study was to analyze MyoD, myogenin myostatin characteristics white during Juvenile fish were divided into three groups: (FC) control, feeding continuously for 42 days, (F5) 5 days 37 refeeding, (F10) 10 32 At...
Abstract Goblet cells (GCs) and endocrine (ECs) play an important role in intestine physiology, few studies currently exist for Amazonian fishes. This study aimed to quantify the distribution of GCs ECs producing cholecystokinin‐8 neuropeptide Y, assessed by mucin histochemistry peptides immunohistochemistry, two species with different feeding habits Tambaqui ( Colossosoma macropomum ) hybrid catfish Pseudoplatystoma reticulatum × Leiarius marmoratus ), omnivore carnivore, respectively. A...
We evaluated growth performance and metabolic responses in Nile tilapia (Oreochromic niloticus) juveniles (30.2 ± 0.9 g) subjected to 1 (F1), 2 (F2), or 3 weeks (F3) of fasting then refed for 10 (10WR) compared controls (FC), which were fed the full 13-week trial. Weight gain specific rate (SGR) during lower all treatments FC. However, refeeding, feed intake/body mass SGR increased F1, F2, F3, inducing partial compensatory growth. The hepatosomatic index (HSI), visceral fat (VFI), liver...
Abstract Based on the importance of tambaqui, Colossoma macropomum , for Latin American aquaculture and digestibility minerals production sustainable aquafeeds, we designed a series trials to determine apparent coefficients (ADCs) phosphorus, calcium, magnesium, manganese, zinc from six protein sources: soybean meal (SBM), corn gluten 60 (CGM60), cottonseed 40, fishmeal (FM), poultry byproduct (PBM), meat bone (MBM); four cereal grain products: corn, wheat middlings, broken rice (BR), bran...
Rivers in the Amazon have among greatest biodiversity world. The Xingu River, one of tributaries has a length 1640 km, draining 510,000 km2 most protected regions on planet. Middle region Brazil been highly impacted by mining and livestock farming, leading to habitat fragmentation due altered water quality. Therefore, comparing two rivers (the preserved River Fresco River) their confluence, aims present study were (1) assess land uses hydrographic basin; (2) determine quality measurements...
O objetivo do projeto foi avaliar o perfil socioeconômico e de consumo peixe da população microrregião Redenção Pará. Foram entrevistadas 498 pessoas entre 0 a 80 anos idade coleta dos dados realizada por meio um questionário semi-estruturado, com 18 perguntas aplicadas em escolas públicas privadas ensino médio, universidade, feiras livres, mercados pontos comércio. elaborado abordando três temáticas: pescado, fatores que influenciam os socioeconômicos consumidores peixe. Foi verificado...
The growth rate of farmed fish is an important factor regarding aquaculture success. An understanding the cellular events that occur in skeletal muscle when undergo periods fasting and refeeding provides information useful developing alternative feeding strategies for improving commercially cultivated species. To evaluate effect 1–3 weeks 10 Nile tilapia juveniles, we analyzed performance changes cellularity expression following related genes: MyoD, myogenin, IGF-1, IGF-1 receptor, MuRF-1,...
O estado do Pará possui grande capacidade hídrica para aumentar a produção de peixes, entretanto atividade aquícola no é incipiente.O objetivo projeto foi caracterizar o perfil dos piscicultores e as pisciculturas na Mesorregião Sudeste Paraense, com isso, foram entrevistados 24 das Microrregiões Redenção Parauapebas (M1), Marabá Tucuruí (M2) São Félix Xingu (M3).Os resultados levantados evidenciaram que prática exercida mais cinco anos nas microrregiões M1 M2, sendo 50% da comercialização,...
O objetivo do trabalho foi avaliar o perfil dos produtores de hortaliças e consumidores nos municípios Xinguara Rio Maria estado Pará. Questionários semiestruturados foram utilizados nas entrevistas que realizadas no formato remoto em diferentes plataformas digitais. A maior parte rurais entrevistados são homens (70%), acima 31 anos idade, atuam na agricultura a mais seis trabalham entre cinco oito horas/dia cultivo vegetais, sendo maioria reside dentro perímetro urbano. produção verduras...
