Optimal growth of shrimp and harvest in a pond is strongly influenced by water quality because this common thing but it cannot be denied that also an important thing. The combination physicochemical parameters biological indicators has become classic way studying quality. Phytoplankton bioindicator affects the productivity vannamei ponds. Currently, farming activities are intensive. This study ...
Although the crustacean heart is modulated by a large number of peptides and amines, few of these molecules have been localized to the cardiac ganglion itself; most appear to reach the cardiac ganglion only by hormonal routes. Immunohistochemistry in the American lobster Homarus americanus indicates that pyrokinins are present not only in neuroendocrine organs (pericardial organ and sinus gland...
The morphology and the drug sensitivity of the strain GYX2014-1 isolated from the hepatic pancreatic tissue of moribund Litopenaeus vannamei were evaluated by conventional culture characteristics, physical and chemical characteristics, and molecular biology methods. Detection of extracellulase and hemolysin activity shows that the isolated GYX2014-1 has protease, lipase, gelatinase activity, bu...
Pacific white shrimp (Litopenaeus vannamei) is the most extensively farmed crustacean species in the world. White spot syndrome virus (WSSV) is one of the major pathogens in the cultured shrimp. However, the molecular mechanisms of the host-virus interaction remain largely unknown. In this study, the impact of WSSV infection on host gene expression in the hepatopancreas of L. vannamei was inves...
In this research Vibrio harveyi strains were isolated and identified from hepatopancreas of Litopenaeus vannamei from Tiab region, Hormozgan province. Shrimps samples were collected from five different ponds in northern and southern Tiab shrimp culture sites. Isolation phase was performed by dilution and inoculation of hepatopancreas samples on thiosulfate citrate bile salts sucrose agar medium...
سطح تکنولوژی پرورش میگو که از آن به سامانه های پرورش میگو یاد می شود، عمدتاً به تراکم لارو، سطح مزرعه، توان سرمایه گذاری پرورش دهنده و میزان محصول وابسته است. بنابراین انتخاب سامانه مناسب پرورش با توجه به توان تولید، حجم سرمایه گذاری لازم و شاخص های بازگشت سرمایه و سودآوری بسیار حائز اهمیت خواهد بود. هدف از تحقیق حاضر، مقایسه دو سیستم گسترده و نیمه متراکم پرورش میگو وانامی (litopenaeus vannamei)...
Abstract Vibriosis is one of the bacterial diseases that caused by a group Vibrio bacteria. The total abundance bacteria exceed normal threshold can cause mass death in vannamei shrimp (Litopenaeus vannamei) aquaculture. study aimed to analyze sp. rearing ponds. was analyzed using plate count agar methode on TCBS and CHROMagar selective media. Histopathological analysis also carried out determi...
Los cultivos larvales de Litopenaeus vannamei presentan altas mortalidades por la presencia del patógeno Vibrio parahaemolyticus, siendo combatido con antibióticos, lo que genera presión selección y resistencia bacteriana. Por se evaluó el extracto en testas Citrus paradisi para inhibir proliferación V. parahaemolyticus mejorar supervivencia L. vannamei, realizado Pontificia Universidad Católic...
