Distribution of trace elements in tissues of shrimp species Litopenaeus vannamei (Boone, 1931) from Bahia, Brazil.
In this study, concentrations of trace elements in tissues of shrimp species (Litopenaeus vannamei) from farming and zone natural coastal located in the northeastern Brazil were investigated. The elements determination was performed by optical emission spectrometry with inductively coupled plasma (ICP OES). The following ranges of concentrations in the tissues were obtained in µg g-1 dry weight...
متن کاملEffect of PSP toxins in white leg shrimp Litopenaeus vannamei Boone, 1931.
Cultured shrimp are often exposed to different toxic products during rearing practices that may affect survival and quality of the product. An evaluation of the effects of paralytic shellfish toxins (PSP) from species of Gymnodinium catenatum in white leg shrimp (Litopenaeus vannamei) has been carried out in this study. Death was observed at doses > 5.0 MU (equivalent to 1.1 mug/g of STX), whil...
متن کاملEvaluation of antibacterial activity of Pseudomonas species isolated from Pacific white shrimp (Litopenaeus vannamei Boone, 1931) against pathogenic Vibrio spp.
In this research antibacterial activity of Pseudomonas isolates derived from hepatopancreas of Litopenaeus vannamei were evaluated against pathogenic Vibrio spp. Shrimp samples collected from 9 different ponds in Tiab region- Hormozgan province. Hepatopancreas samples of collected shrimps were inoculated in three different isolation media. Pseudomonas Isolation Agar medium revealed highest yiel...
متن کاملMicrobiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)
Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...
متن کاملSubstitution of fish meal with plant protein sources and energy budget for white shrimp Litopenaeus vannamei (Boone, 1931)
Fish meal (FM) has long been considered an essential ingredient for the formulation of shrimp feeds. Until recently, 12%FM was considered a minimum amount, below which weight gain would become reduced due to a reduction in feed intake. In order to test this perceived minimum value, an experiment was conducted on a long-term basis with 4 replicates. Four practical isonitrogenous and isoenergetic...
