Effect of sodium phytate on growth and tissue mineralization of Penaeus japonicus and Penaeus vannamei juveniles

Aquaculture, 1989
Feeding experiments were conducted to determine the effect of sodium phytate as a phosphorus source for Penaeus japonicus and Penaeus vannamei juveniles. The dietary value of this compound was compared with that of disodium phosphate in terms of survival rate, feed intake, growth rate, number of molts as well as the calcium and phosphorus content of ...

A simple stress test for Penaeus vannamei postlarvae

Aquaculture, 1998
Abstract The effects of age on resistance to low salinity and formalin stress were determined in early Penaeus vannamei postlarvae (PL) with acute static bioassays. Two-hour median lethal concentrations (2 h-LC50) of formalin were 274, 288, 298 and 293 ppm for PL ages of 1, 2, 3 and 4 days (PL1–PL4), respectively.

Evaluation of five carbohydrate sources for Penaeus vannamei

Aquaculture, 1993
Abstract Utilizing chromic oxide as an inert marker, apparent digestibility coefficients of five carbohydrate sources were evaluated in 8.8 g Penaeus vannamei . Test diets for each ingredient, wheat starch, whole wheat, Nutribinder ® , sorghum and steam cracked corn, were prepared containing 70% semi-purified reference diet and 30% of the test ...

Fucosylation of hemocyanin is critical for antibacterial immunity in Penaeus vannamei

Fish & Shellfish Immunology
Posttranslational modifications (PTMs) play a pivotal role in expanding the function of immune related proteins, especially during pathogen infections. However, the precise impact of PTMs on the functional diversity of proteins such as respiratory glycoproteins and hemocyanins remains incompletely understood.

Study on the Acoustic Signal Characteristics of Feeding Activity of Penaeus Vannamei

2020 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2020
To solve the problem of intelligent feeding of Penaeus Vannamei, this paper presents a study on the characteristics of acoustic signals during feeding, which can adaptively control the feeding amount. In this experiment, a sound acquisition system was designed for the weak sound signal of feeding of Penaeus Vannamei.

Single nucleotide polymorphism associated with disease resistance in Penaeus vannamei

Journal of Invertebrate Pathology, 2020
Despite the considerable number of genetic markers published for Penaeus vannamei, the classification of these markers and their standardization in specific databases is still insufficient. As a consequence, access to these markers is difficult, hampering their application in genetic association studies.

Immunofluorescence detection of Ecytonucleospora hepatopenaei (EHP) in Penaeus vannamei

Journal of Microbiological Methods
Hepatopancreatic microsporidiosis (HPM), caused by the microsporidium Ecytonucleospora hepatopenaei (EHP) leads to retarded growth and enhanced susceptibility to other diseases in shrimp resulting in a major loss for the shrimp industry worldwide. It is little understood how EHP infects its host and hijacks its cellular machinery to replicate and exert

Mating behaviour in the penaeid shrimp Penaeus vannamei

Marine Biology, 1988
Mating behaviour of Penaeus vannamei was observed during January, 1986. Mating behaviour was divided into four phases: (1) approach, (2) crawling, (3) chasing, and (4) mating. Male mating and spermatophore transfer to the mature female take place at intermolt stage C4. The glutinous spermatophore emitted from the male can be transferred onto the female

Silver nanoparticles induce histopathological alterations in juvenile Penaeus vannamei

Environmental Science and Pollution Research, 2020
The objective of this study was to evaluate the histopathological alterations in juvenile Penaeus vannamei caused by silver nanoparticles (AgNPs) for two types of experiments: at sublethal concentrations of 3.6 to 7.1 μg/μL of metallic silver (Ag) for a short period up to 72 h and for 2.6 to 7.9 μg of Ag/μL for the long period up to 264 h. The severity
