Abstract The hepatopancreas of the shrimp is the target organ of several pathogens. Diagnosis of diseases of the hepatopancreas usually required an isolation of the organ and the process cannot avoid sacrificing the shrimp. To save life of the animal, this study was aimed at taking hepatopancreatic tissue from the shrimp by biopsy process. Thirty-two

Thiamin Requirement of Juvenile Shrimp (Penaeus monodon)
The Journal of Nutrition, 1991In a 9-wk feeding trial, juvenile shrimp (Penaeus monodon) were fed semipurified diets containing seven levels (0, 20, 40, 60, 80, 160 and 320 mg/kg diet) of supplemental thiamin hydrochloride. The dietary thiamin level required for optimal growth in P. monodon was found to be approximately 14 mg/kg diet based on hemolymph (blood) thiamin analysis. The

Interspecific hybridization of the tiger prawns Penaeus monodon and Penaeus esculentus
Aquaculture, 1995Interspecies hybrids were produced by artificial insemination of Penaeus monodon females with P. esculentus males. Successful spawnings were achieved from two of the 13 matings attempted. Hatch rates were low (< 4%) but 85% of the vigorous larvae produced survived to PL1.

Culture of Penaeus monodon in a recirculating system
Aquacultural Engineering, 1998In this decade, the production of Penaeus monodon using the traditional open pond method decreased seriously due to disease that spread via seawater. In order to prevent the introduction of pathogenic micro-organisms from seawater, a recirculating system was constructed and tested in this study.

Reproductive quality of male Penaeus monodon
Aquaculture, 1993Abstract The reproductive performance of unilaterally eyestalk-ablated wild male Penaeus monodon was compared with that of unablated prawns (controls). After being stocked for 6 weeks in flow-through tanks, ablated males showed significantly higher sperm count (153.6 × 10 6 vs.77.5 × 10 6 ), less abnormal sperm (45.5% vs 73.3%), larger sperm head ...

Presence of Penaeus monodon densovirus in the ovary of chronically infected P. monodon subadults
Diseases of Aquatic Organisms, 2018Shrimp infected with Penaeus monodon densovirus (PmoDNV) usually display no specific gross signs, but heavy infections can kill postlarvae and retard juvenile growth. In the present study, samples of hepatopancreas, feces, gonads and hemolymph were isolated from male and female P. monodon subadults chronically infected by PmoDNV.

Artemia is not a vector for monodon baculovirus (MBV) transmission to Penaeus monodon
Journal of Fish Diseases, 2008Monodon baculovirus (MBV) of penaeid shrimp has been associated with high mortalities in hatchery-reared larval, post-larval and early juvenile stages of Penaeus monodon and is thought to have originated from Taiwan (Lightner, Redman & Bell 1983). MBV is pathogenic to several species of shrimp such as P. monodon Fabricius, P.

ผลการใช้กรดเบนโซอิกเป็นอาหารเสริมต่อการเติบโตในกุ้งกุลาดำ Penaeus monodon
การเสริมกรดเบนโซอิกในกุ้งกุลาดำ Penaeus monodon ในตู้กระจก และบ่อปูนซีเมนต์ พบว่ากรดเบนโซอิกไม่กระตุ้นการเติบโตของกุ้งกุลาดำในการเลี้ยงกุ้งทั้ง 2 ครั้ง และไม่พบความแตกต่างของอัตราการเติบโตและการรอดชีวิตของกุ้งระหว่างกุ้งกลุ่มที่ได้รับกรดเบนโซอิกและกลุ่มควบคุมที่ไม่ได้รับกรดเบนโซอิก จากการทดสอบความต้านทานต่อการเหนี่ยวนำให้เกิดโรคด้วย Vibrio harveyi สายพัopenaire +1 more source
Colourimetric PCR-based detection of monodon baculovirus in whole Penaeus monodon postlarvae
Journal of Virological Methods, 1998The development of a nested polymerase chain reaction (PCR) assay is described to detect low concentrations of monodon baculovirus (MBV) DNA from total Penaeus monodon postlarval DNA. A modified DNA extraction procedure was also developed to circumvent problems associated with co-purification of PCR inhibitors in total DNA extracted from whole ...

ผลของการใช้ยีสต์สกัดทดแทนปลาป่นบางส่วนในอาหารต่อการเติบโตของกุ้งกุลาดำ Penaeus monodon
การศึกษาครั้งนี้มีวัตถุประสงค์เพื่อพัฒนาอาหารสำเร็จรูปที่ใช้ในการเลี้ยงกุ้งกุลาดำ Penaeus monodon โดยการใช้ยีสต์สกัดทดแทนปลาป่นบางส่วนในอาหารต่อการเติบโตของกุ้ง ออกแบบการทดลองแบบ 2x4 factorial design โดยมี 2 ระดับโปรตีน (ร้อยละ 25 และ 35) และ 4 ระดับของยีสต์สกัด (ร้อยละ 0, 4, 8 และ 12) ที่ใช้เป็นส่วนผสมในอาหาร โดยทำการทดลอง 3 ครั้ง ผลการทดลองพบว่า ก ...openaire +1 more source
