Traditional Vietnamese herbal species were examined for their antimicrobial activity and disease resistance in whiteleg shrimp. In-vitro screening, the extracts of ten herbs conducted to test inhibition ability against Vibrio parahaemolyticus , causing acute hepatopancreatic necrosis disease. The results showed that five out species, including Pithecellobium dulce Melaleuca leucadendron Eucalyp...

La investigación consistió en comparar dos métodos de adición oxitetraciclina (OTC) el alimento para camarón, así como efecto su desarrollo y la acumulación músculo hepatopáncreas Penaeus vannamei. Se realizó un bioensayo durante 30 días empleando 180 camarones juveniles utilizando formulaciones alimentarlos con(OTC-1 OTC-2). Los alimentos medicados se administraron 14 días, posteriormente les ...

A cytosolic manganese superoxide dismutase gene (Es-cMnSOD) was cloned from the Chinese mitten crab Eriocheir sinensis, using reverse transcription-polymerase chain reaction and the rapid amplification of cDNA ends. The open reading frame of Es-cMnSOD is 867 bp in length and encodes a 288-amino acid protein without a signal peptide. The calculated molecular mass of the translated protein of Es-...

Fuzzy Inductive Reasoning (FIR) is a qualitative inductive modeling and simulation methodology for dealing with dynamical systems. It has proven to be a powerful tool for qualitative model identi cation and prediction of future behavior of various kinds of dynamical systems, especially from the soft sciences, such as biology, biomedicine, and ecology. This paper focuses on modeling aspects of t...

Shrimp is extensively cultured worldwide. Shrimp farming is suffering from a variety of diseases. Probiotics are considered to be one of the effective methods to prevent and cure shrimp diseases. Exiguobacterium arabatum W-01, a gram-positive and orange-pigmented bacterium, was isolated from the intestine of a healthy Penaeus vannamei specimen. Whole-genome sequencing revealed a genome of 2,914...

There is currently concern and controversy in the shrimp industries of the Americas about the risk posed by the importation and reprocessing of shrimp infected with white spot syndrome virus (WSSV) and yellow head virus (YHV). To further understand the risk, more knowledge concerning the quantitative virus load of infected shrimp is needed. The present study was carried out to better define, us...

Glutathione S-transferases (GSTs) are a family of multifunctional phase II enzymes that are involved in the detoxification of exogenous and endogenous compounds. In this study, a full-length cDNA of Mu-class GST (PmMuGST) was isolated from the hepatopancreas of Penaeus monodon using rapid amplification of cDNA ends method. The full length cDNA of PmMuGST is 867 bp, contains an open read frame o...

Waste materials derived from shrimp processing signify 40 to 45 % of the weight of the catch or harvest. For Biotechnology, waste materials are secondary material, as contrast of raw materials, to generate value-added products, such as chitin, protein, and pigments. We used the pH-shift and enzymatic autohydrolysis processes to obtain protein concentrates from the cephalothorax of whiteleg shri...

We investigated the effect of starvation as a stimulant of the digestive system on digestive proteinase activities in the white shrimp Penaeus vannamei. The starved organisms were sampled periodically according to the molting stage and compared with a continuously fed group. Molting stage was included as an independent variable. Most analyzed variables, except for trypsin, were more affected by...

Traceability is considered the most important requirement for shrimp products exported to global markets. However, implementing traceability in shrimp-exporting countries challenging because of limited production at local supply chain and lack financial welfare awareness. This study aims investigate expected farm-gate price implementation using a double-bound dichotomous choice experiment. The ...
