“…As shown in Table 1, means of morphometric measurements, TL, CL, TA and WT of M. rosenbergii were found to differ significantly (p<.05) according to population source. Consistently, similar results were reported by Kitcharoen et al (2010), Munasinghe and Thushari (2010), Pillai et al (2011) and Thanh et al (2009). Four growth-related quantitative traits were assessed for progenies raised in grow-out ponds.…”

Thailand was second only to P.R.China in annual production of giant river prawn. This article briefly describes the seed production of giant river prawn technology in Thailand and notes that broodstock management has paid scant attention to genetic issues. There are, however, ongoing selective breeding programmes on giant river prawn aimed to improve growth and disease resistance. In the conventional culture technology, postlarvae are stocked at a high density and prawns are harvested partially. The cropping period is long and the practice has led to disease outbreaks and deteriorated pond bottoms that result in frequent detection of antibiotic residue. The improved culture technology involves manual sexing of the prawns at 3 months and restocking only the male prawns into new ponds at low density. The technique gives higher yield and reduces incidence of disease and thus the need for prophylactics. The constraints to giant river prawn culture business in Thailand include low yield and a limited export market. The article describes three ways to expand and sustain the business of giant river prawn farming in the country: development of more genetically improved strains; culture of all-male stock, and new culture techniques.

“…Although techniques for the genetic improvement of prawn strains are still in their early stages compared with those for domesticated fish species (Bart and Yen, 2003;Nhan et al, 2009;Kitcharoen et al, 2010;Thanh et al, 2010), our findings may serve as a key aid for researchers performing further investigations of M. rosenbergii and other prawns.…”

a b s t r a c tThe genetic differences between the blue claw male (BC), orange claw male (OC) and small male (SM) morphotypes of male freshwater prawns were assessed using microsatellite DNA markers. Thirty individuals from each of the three groups of male prawns were collected from a hatchery rearing system in Port Dickson, Negeri Sembilan, Malaysia. Significant differences in growth were observed between the three groups. The total numbers of alleles per locus in the BC, OC and SM groups were found to be 23, 27 and 21, respectively from all loci. The average observed heterozygosities (H o ) ranged from 0.48 to 0.56 across all loci in the three groups. The mean F IS of −0.018 indicated an excess of heterozygosity. The pair-wise comparisons and the F ST values revealed significant genetic differentiation across the groups. The greatest genetic distance was observed between the BC and SM groups and lowest one was between the BC and the OC groups.
