This study aimed to quantify the accumulation and elimination of Enrofloxacin (ENRO) and Ciprofloxacin (CIPRO) in cultivated Litopenaeus vannamei under controlled laboratory and farm conditions. Laboratory- and farm-raised shrimp were given feed supplemented with 200 mg/kg ENRO for 14 days, followed by a 16-day diet without antibiotics. The levels of ENRO and CIPRO were analyzed by High Perform...

This study evaluated the susceptibility of Penaeus vannamei, Kona stock-line, to infection by an isolate of Taura syndrome virus from Belize (TSV-BZ) under hyperthermic conditions (32 degrees C). Shrimp exposed to the reference Hawaii-94 isolate of TSV (TSV-HI) showed resistance to infection at 32 degrees C as demonstrated by the absence of mortality, histopathological lesions and decreased vir...

As earlier observations on peroral infectivity of WSSV in white-legged shrimp are conflicting, here, a standardized peroral intubation technique was used to examine (i) the role of the physical composition of the viral inoculum and (ii) the barrier function of the PM. In a first experiment, the infectivity of a WSSV stock was compared by determining the SID50 by intramuscular injection, peroral...

Budidaya udang merupakan salah satu kegiatan budidaya yang mampu meningkatkan perekonomian masyarakat pesisir. Akan tetapi, juga dapat memberikan dampak negatif terhadap lingkungan. Kondisi plankton pada lingkungan digunakan sebagai parameter tingkat pencemaran Pada penelitian ini, dilakukan monitoring jenis plankton, struktur komunitas dan indek saprobitas di tiga kawasan vannamei Kecamatan Po...

Methods Serum allergen-specific IgE of 105 subjects were quantified using ImmunoCAP and ImmunoCAP ISAC biochips. The subjects were classified based on a convincing clinical history and food challenge testing (FC) (dose=70g) to Penaeus monodon and Litopenaeus vannamei. Group1A: Either SA with FC positive to either shrimp (n =22) or SA admitted to emergency departments for severe reactions but no...

Prospect of antibacterial agents may provide an alternative therapy for diseases caused by multidrug-resistant bacteria. This study aimed to evaluate the in vitro bioactivity of Moringa oleifera seed extracts against 100 vibrios isolated from the marine shrimp Litopenaeus vannamei. Ethanol extracts at low (MOS-E) and hot (MOS-ES) temperature are shown to be bioactive against 92% and 90% of the ...

Pacific white shrimp, Litopenaeus vannamei, is the major species used in aquaculture of shrimp as of food for humans. Feed used in commercial cultivation of shrimp increasingly contains plant protein as a nutritional source, which has the advantage over animal protein in terms of both cost and sustainability. However, a problem with the use of plant protein, such as soybean meal, is that it lac...

bacterial diseases have been reported to be the major limiting factor in shrimp production. the use of natural products such as antimicrobials has been reported as a solution to the problem. the crude extract of a red seaweed laurencia snyderiae obtained from the persian gulf was evaluated for shrimp growth performance and to determine in vivo efficacy of this seaweed in the prevention of shrim...
