The midgut chymotrypsins of shrimps (Penaeus monodon, Penaeus japonicus and Penaeus penicillatus)

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1991
The midgut chymotrypsins (EC 3.4.4.5) of three species of shrimps, Penaeus monodon, Penaeus japonicus and Penaeus penicillatus were purified and studied in detail to clarify previous ambiguity in their identification. In each of the species there are two major forms of chymotrypsin, both single-chained with three disulfide bonds.

Carbohydrate digestion in Penaeus monodon

Marine Biology, 1994
Using crude homogenates from the digestive system of pond-cultured Penaeus monodon, carbohydrase activity was demonstrated toward a wide variety of substrates differing in sources and complexity. The largest concentration of this activity was found to be localised within the midgut gland.

Thiamin Requirement of Juvenile Shrimp (Penaeus monodon)

The Journal of Nutrition, 1991
In 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

Needle biopsy of the hepatopancreas of the black tiger shrimp Penaeus monodon with Penaeus monodon densovirus detection

Aquaculture, 2018
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

Culture of Penaeus monodon in a recirculating system

Aquacultural Engineering, 1998
In 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, 1993
Abstract 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 ...

Interspecific hybridization of the tiger prawns Penaeus monodon and Penaeus esculentus

Aquaculture, 1995
Interspecies 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.

A suctorean parasite of Penaeus monodon larvae

1977
A pathogenic suctorean, identified as Ephelota gemmipara was observed in P. monodon larvae spawned and reared in tanks. Commonly found to inhabit hydroid colonies, E. gemmipara has a stalked body with two types of tentacles, the sucking and piercing types, and was observed to reproduce by multiple exogenous budding.

Artemia is not a vector for monodon baculovirus (MBV) transmission to Penaeus monodon

Journal of Fish Diseases, 2008
Monodon 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.
