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...

The shrimp commodity in Indonesia is a leading the fisheries sector which produced from aquaculture activities. Apart that, it also because farming business activities are able to make sizeable contribution earning foreign exchange, cultivator income, creating jobs, and opportunities. purpose of this research analyze socio-economic impact vannamei (Litoanaeus vannamei) fishery on local communit...

Vannamei shrimp (Litopenaeus vannamei) is one of the leading commodities in Indonesian aquaculture. The cultivation potential that developing at this time with intensive technology. However, along development technology, it experienced problems, namely crop failure caused by a decrease water quality. This study aims to examine physical and chemical dynamics vannamei pond cultivated semi-biofloc...

Although the expression of miRNAs has been widely applied to investigate on gonads, role in gonadal development white Pacific shrimp (Litopenaeus vannamei) remains unknown. In this study, we performed high-throughput sequencing identify sex-related microRNAs (miRNAs) that elucidated regulatory mechanisms differentiation L. vannamei. We obtained a total 29,671,557 and 28,526,942 raw reads from o...

Cathepsin B is a cystein proteinase scarcely studied in crustaceans. Its function has not been clearly described in shrimp species belonging to the sub-order Dendrobranchiata, which includes the white shrimp Litopenaeus vannamei and other species from the Penaeidae family. Studies on vertebrates suggest that these lysosomal enzymes intracellularly hydrolize protein, as other cystein proteinases...

The nuclear factor-kappa B (NF-κB) pathways play important roles in innate immune responses. IκB is the main cytoplasmic inhibitor of NF-κB. In this study, we identified the LvCactus gene from Litopenaeus vannamei, which is the first cloned IκB homologue in subphylum Crustacea. LvCactus contains six predicted ankyrin repeats, which show similarities to those of Cactus proteins from insects. LvC...

Infectious diseases especially those caused by bacterial and viral pathogens are serious loss factors in shrimp farming. In this study, bacteria were isolated from the gut and hepatopancreas of stressed shrimps obtained from a commercial farm. The isolates were screened on Thiosulfate citrate bile salt sucrose (TCBS) agar plates for the selection of Vibrio species. Presumptive vibrios were char...

The QM, firstly identified as a putative tumor suppressor gene from human, has been confirmed to possess varieties of functions in a range of organisms. In the present study, the cDNA that encodes a 220-amino-acid QM protein with calculated molecular mass of 25.5 kDa and isoelectric point of 10.07 was characterized from the Pacific white shrimp Litopenaeus vannamei. Analysis of the deduced amin...
