There is an increasing interest in essential oils extracted from Verbenaceae plant species as potential sources of biologically active compounds that could provide a starting point for designing novel phyto-pharmaceuticals aquaculture. The present study was aimed to investigate the chemical composition, antioxidant activity, acute toxicity and antimicrobial effects against Vibrio parahaemolyticus Lippia alba L. origanoides. Approximately 23 components were identified quantified by gas...
RESUMO Este trabalho teve como objetivo avaliar a fauna parasitária de tambaquis na região do Baixo São Francisco-AL/SE-Brasil e correlacionar os índices prevalência intensidade média com fatores bióticos abióticos. Foram coletados 252 espécimes para análise parasitológica 10 pisciculturas. Os parasitos foram contabilizados, identificados, determinaram-se média, que correlacionados Dos peixes coletados, 65,5% estavam parasitados por pelo menos um táxon. encontrados táxons: Monogeneas,...
The aim of this study was to evaluate plankton communities in Penaeus vannamei nurseries under different frequencies adjustment on Ca:Mg:K ratio low salinity water and with synbiotic system. A nursery culture carried out for 40 days, using 2000 shrimp m⁻³. Following treatments were established: 1IA (Ca:Mg:K 1:3:1 day 1); 2IA 1 20); 3IA 1, 10, SW (seawater - 31 g L−1); SWD diluted a 2.3 L−1). Rice bran processed by probiotic microorganisms used as an organic carbon source. Treatments did not...
Infectious myonecrosis virus (IMNV) has been causing a progressive disease in farm-reared shrimps Brazil and Indonesia. Immunodiagnostic methods for IMNV detection, although reliable, are not employed currently because monoclonal antibodies (MAbs) against this available. In study, fragment of the major capsid protein gene, comprising amino acids 300-527 (IMNV(300-527)), was cloned expressed Escherichia coli. The nucleotide sequence recombinant IMNV(300-527) displayed high degree identity to...
RESUMO: O presente trabalho descreve a atividade antibacteriana do óleo essencial e extrato etanólico das folhas de Alpinia zerumbet (colônia) sobre cepas Staphylococcus aureus isoladas vacas com mastite subclínica padrão ATCC 29213 25923, por meio método difusão em ágar. Foram utilizados 10 tratamentos contendo diferentes concentrações (100,0; 50,0; 25,0; 12,5 6,3 mg.mL-1) o grupo controle (álcool etílico 50% Tween 1%). Os constituintes majoritários foram p -cimeno (32,72%), 1,8-cineol...
In peneide shrimp, diseases caused by Vibrio species are the source of serious economic losses worldwide. Essential oils from Lamiaceae sources bioactives for aquaculture, with potential antimicrobial and antioxidant activity. The aim was to investigate chemical composition, activity effects essential five against parahaemolyticus. Approximately forty-eight components were identified quantified gas chromatography-mass spectrometry (GC-MS) flame ionization detection (GC-FID). predominant...
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...
ABSTRACT We investigated the effect of Alpinia zerumbet essential oil on quality and shelf life tambaqui (Colossoma macropomum) fillets stored under refrigeration (10.0 ± 0.5 °C) for 14 days. The treatments were A. at 0.75% v v-1 (AEO 0.75%), 1.5% 1.5%) a control (no oil). sample determined by total psychrotrophic count (TPC) chemical parameters (pH, volatile basic nitrogen, centesimal composition thiobarbituric acid reactive substances - TBARS) zero, seven days storage time. TPC decreased...
RESUMO Há muitos estudos voltados à redução do volume de resíduos provenientes da indústria pesqueira. Esses são uma importante fonte matéria-prima em sistemas orgânicos produção ao serem compostados. O objetivo deste trabalho foi avaliar os parâmetros teores totais nutrientes composto orgânico confeccionado com pescado, comparando-o a outras duas composições, além utilizá-lo como substrato na mudas alface (Lactuca sativa). Na avaliação alface, utilizou-se o delineamento inteiramente...
The century-old mangrove crab Ucides cordatus Linnaeus, 1763 harvesting is a traditional activity of Northeastern Brazilian coastal communities, who use it as food, source income and cultural reference. extractivism marketing this crustacean essential for the socio-economic development states Maranhão, Piauí Ceará. aim study was to carry out monitoring landing in Ilha Grande, PI. Interviews were conducted with gatherers transporters obtain information about harvesting, landed volume, market...
The Ucides cordatus mangrove crab is one of the most economically important crustaceans in Brazil, being a source income and work for fishing communities. Its consumption Northeastern cuisine attractions, supporting thematic restaurants greatly appreciated by tourists. Crabs not sold fishermen or traders are processed locally meat pasta extraction. This aimed to diagnose socioeconomic situation workers involved this activity, as well hygienic-sanitary conditions processing, handling...
