Ridgetail white prawn Exopalaemon carinicauda with body weight of(0.175±0.065) g was raised in a 50 cm×40 cm×30 cm water tank at a salinity of 22 and water temperature of 25°C to investigate the effects of Ca²⁺ concentration(100 mg/L, 200 mg/L, and 300 mg/L), Mg²⁺ concentration(300 mg/L, 600 mg/L,...

White spot disease (WSD) in shrimp is an acute infectious disease caused by white spot syndrome virus (WSSV). WSD has seriously threatened the security of shrimp farming, causing huge economic losses worldwide. As there is currently no effective treatment for WSD, developing early detection...

Mud Crab Reovirus (MCRV) is a major pathogen of cultured mud crab Scylla paramamosain. Early studies showed that the mortality rate caused by MCRV was high. However, current studies show that MCRV has been widely present in cultured mud crab ponds, and the mortality rate has dramatically decreased, ...

A feeding experiment which lasted 240 days was carried out to study the effects of different sizes and different diets on the edible part content and body composition of the female Chinese mitten crab (Eriocheir sinensis). The results showed that there was no significant influence on hepatopancreas ...

The aim of this study was to compare total carotenoid content (TCC) in tissues, and its correlation with shell color between four different shell color strains of Pinctada fucata. A total of 120 individuals (30 golden shells, 30 red shells, 30 black shell and 30 white shells) of P. fucata of...

Integrated culture of pearl mussel Hyriopsis cumingii and planktivorous fishes, such as Hypophthalmichthys molitrix and Aristichthys nobilis is widely used in commercial freshwater pearl mussel farming. Previous studies reported that stocking Ctenopharyngodon idella and Carassius auratus gibelio in ...

Acute hepatopancreatic necrosis disease (AHPND) is a major bacterial acute disease of shrimp caused by Vibrio infection, which can lead to high mortality and cause huge economic losses to the shrimp farming industry. Therefore, the development of early, rapid, and accurate AHPND diagnostic methods ...

The Chinese mitten crab, Eriocheir sinensis, is an economically valuable aquaculture species. Prior to sale, farmed crabs are often fattened with pellet feed or wild fish. In this study, PacBio Sequel sequencing was used to determine the bacterial flora in the intestinal tracts and gill tissues of...

The acute hepatopancreas necrosis disease (AHPND) caused by Vibrio species containing the virulence Photorhabdus insecticidal-related genes, PirA^vp and PirB^vp, is a high-mortality-rate disease in shrimp farming with strong transmission, quick onset, and severe symptoms. It is vital to control the...

Acute hepatopancreatic necrosis disease (AHPND) is a recently discovered shrimp disease that has become a severe threat to global shrimp -farming industry. The causing agents of AHPND were identified as Vibrio parahaemolyticus and other vibrios harboring a plasmid encoding binary toxins PirA^vp/PirB...
