Substitution 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...
متن کاملMercury accumulation and metallothionein expression from aquafeeds by Litopenaeus vannamei Boone, 1931 under intensive aquaculture conditions.
This study describes the accumulation of Hg and metallothionein gene expression in Litopenaeus vannamei Boone, 1931 with aquafeeds as the major source of Hg. Trials were conducted under controlled conditions in experimental tank facilities with high (indoor tanks) and low (outdoor tanks) Hg aquafeeds concentrations. Aquafeeds were the sole source of Hg for the shrimps and concentrations varied ...
متن کاملDistribution 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 کاملApplication of Bacillus amyloliquefaciens as probiotic for Litopenaeus vannamei (Boone, 1931) cultivated in a biofloc system
Probiotics can improve growth, survival and resistance to pathogenic organisms of the cultivated species in aquaculture systems with water recirculation. However, their possible benefits on biofloc systems have been less studied. In this study, the benefits of Bacillus amyloliquefaciens bacterium, on a biofloc culture of Litopenaeus vannamei were evaluated. B. amyloliquefaciens was applied as d...
