Four species of penaeid prawn cultured in Australia (Penaeus monodon, Penaeus esculentus, Marsupenaeus japonicus and Fenneropenaeus merguiensis) were injected with a virulent preparation of gill-associated virus (GAV). P. monodon (average weight = 8.9, 13.9 and 19.2 g), P. esculentus (average weight = 19.5 g), F. merguiensis (average weight = 10.5 g), and small (average weight = 5.8 g) M. japon...
Structural Insights into the Cytotoxic Mechanism of Vibrio parahaemolyticus PirAvp and PirBvp Toxins
In aquaculture, shrimp farming is a popular field. The benefits of shrimp farming include a relatively short grow-out time, high sale price, and good cost recovery. However, outbreaks of serious diseases inflict serious losses, and acute hepatopancreatic necrosis disease (AHPND) is an emerging challenge to this industry. In South American white shrimp (Penaeus vannamei) and grass shrimp (Penaeu...
The level of the heavy metal in green tiger shrimp (Penaeus semisulcatus) and crab (Portunus pelagicus) caught off the Persian Gulf near Bushehr province were investigated. This study was performed to evaluate instrumental neutron activation analysis (INAA) to analyze heavy metal concentration in crab and shrimp whole body tissue. The order of the swimmer crab and shrimp heavy metal concentrati...
Closing the complex life cycle of closed thelycum shrimp in captivity is one fundamental challenges breeding programs. In present study, we investigated sexual maturity, broodstock development, and spawning performance two generations captive-reared Indian white shrimp, Penaeus indicus , over 36 months originated from a single stock wild brooders. The post larvae (G N -1) produced P. 0 ) P.L. -...
We assessed the metal-accumulating ability of the shrimp Penaeus indicus for Nickel (Ni) in 2008. Shrimps were seasonally (autumn and winter) collected from Jask coastal area, East of Hormuzgan province in the Persian Gulf. The samples were washed with seawater and dried with the help of freeze dryer and digested using a microwave digester in a super-pure nitric acid solution. The Nickel concen...
خشک کردن کف پوشی فرایندی است که ابتدا ماده غذایی به کف پایدار تبدیل شده سپس در دمای نسبتاً پایین خشک می شود. در این پژوهش، شرایط تولید کف میگو با استفاده از روش سطح- پاسخ بهینه سازی شد. متغیرهای مستقل شامل غلظت صمغ (4/0-1/0 %) (وزنی/وزنی)، نسبت میگو به آب (1:6-1:2) (وزنی/وزنی) و زمان هم زدن (6-2 دقیقه) و پاسخ های اندازه گیری شده (متغیرهای وابسته) شامل دانسیته کف و حجم زهکشی (بیان کننده پایداری ک...
The virucidal effect of pH and salinity on Penaeus monodon baculovirus (MBV) was investigated by water borne inoculated methods exposing PL12 Penaeus semisulcatus for 10 hours and observing for 10 days at temperature 28- 30°C. For this purpose, one thousand virus free PL12 of P. semisulcatus were divided into five groups and each group placed in a 10 L plastic basin containing chlorine-treated ...
In vivo effect of lead on Na, K(+)-ATPase was studied in plasma membrane/mitochondrial fraction of P. indicus post-larvae (PL), exposed to 30 days to a sublethal concentration (1.44 ppm) of lead. A significant (P < 0.05) decrease in the enzyme activity was observed for exposed PL with respect to their controls at different intervals except 24hr. Further the substrate (ATP) and ion (Na+ and K+)-...
