Coastal aquaculture in Bangladesh consists mainly of two shrimp species (Penaeus monodon and Macrobrachium rosenbergii). Currently, there are about 16,237 marine shrimp (P. monodon) farms covering 148,093 ha and 36,109 fresh water shrimp (M. rosenbergii) farms covering 17,638 ha coastal area. More than 0.7 million people are employed in the farmed shrimp sector and in 2005-2006 the export value...

این تحقیق در طی فروردین الی مهر 1393 بر روی مجموع 10645 میگو شامل 5667 نر، 4978 ماده و 58 میگو نابالغ صورت گرفت. نسبت جنسی نر به ماده 1: 1/14 برآورد گردید. دامنه طول کل و وزن در این میگو به ترتیب 81/5-6/5 میلی متر و 13/69-0/01 گرم به دست آمد. میانگین طول و وزن در میگوهای نر (طول کل 46/6میلی متر و وزن 2/76 گرم) بیش تر از ماده ها (میانگین طول کل 44/5میلی متر و وزن 2/14گرم) بود. ارتباط طول و وزن ب...

A study was undertaken to determine the most effective element among the commonly used antimicrobial agents, especially in the body muscle of black tiger shrimp (Penaeus monodon) and giant freshwater prawn (Macrobrachium rosenbergii) on the basis of different chemical interventions. Using 10 ppm calcium hypochlorite, the microbial load has been reduced more significantly (p>0.001) than trisodiu...

This study documents the complete larval development of the Monkey River Prawn Macrobrachium lar using a new greenwater rearing technique. Approximately 6,000 larvae were reared for 110 days at an initial stocking density of 1 ind./6 L. Salinity at hatch was 10 ± 2 ppt and progressively increased to 30 ± 2 ppt until decapodids had metamorphosed. Temperature was maintained at 28 ± 0.5°C, pH at 7...

Macrobrachium aemulum madhusoodani Pillai & Unnikrishnan (2013) was recently described based on material from the Neyyar River, Kerala, India as a new subspecies of M. aemulum (Nobili, 1906). As however, both species and subspecies names are considered part of the species-group for nomenclatorial purposes (ICZN, Art. 45.1), the name is a junior homonym of Macrobrachium madhusoodani Unnikrishnan...

Macrobrachium indianum new species is described from the Pambar River, Kerala, S. India. The species shares certain characters with M. gurudeve Jayachandran & Raji, 2004, M. bombayense Almelker & Sankolli, 2006 and M. kulkarnii Almelker & Sankolli, 2006, while it differs remarkably from these three species in distinctive diagnostic characters: rostral formula 7-8/3-4 with 1 postorbital teeth, o...

Early malacological literature suggests that the outbreak of schistosomiasis, a parasitic disease transmitted by aquatic snails, in the Senegal River basin occurred due to ecological changes resulting from the construction of the Diama dam. The common treatment, the drug praziquantel, does not protect from the high risk of re-infection due to human contact with infested water on a daily basis. ...

BACKGROUND The endemic Australian freshwater prawn, Macrobrachium koombooloomba, provides a model for exploring genes involved with freshwater adaptation because it is one of the relatively few Macrobrachium species that can complete its entire life cycle in freshwater. METHODS The present study was conducted to identify potential candidate genes that are likely to contribute to effective fre...

The embryonic changes during the development of the freshwater prawn, Macrobrachium americanum are described from observations made on live embryos based on the percentage-staging method. Eggs were observed with a stereomicroscope to obtain descriptions of embryonic periods. This prawn has an incubation time of 18 days at 24◦C. Ten periods are described and illustrated. A comparison of this dev...
