In wireless networks, bringing together theory and practice, i.e., going all the way from designing a protocol or application, evaluating it analytically and through simulations to having a working implementation, is far from trivial. This is due especially to the challenges raised by the spatially and time variant nature of the wireless channel. As a consequence, wireless protocol research typ...

Anchistus custos Forsk&l is the only common prawn commensal with bivalves of the family Pinnidae in Singapore waters. The whole morphology shows pronounced modifications connected with the commensal mode of life. The second legs are large and massive and show marked positive allometry in the male but appear to have little function in the general life of the animal. The animal occurs wherever th...

Exposure of prawns to dark- or light-coloured substrates is known to trigger a strong colour adaptation response through expansion or contraction of the colouration structures in the prawn hypodermis. Despite the difference in colour triggered by this adaptive response, total levels of the predominant carotenoid pigment, astaxanthin, are not modified, suggesting that another mechanism is regula...

The research investigated the impacts of inclusion of column feeder rohu (Labeo rohita) on growth and production in freshwater prawn-carp-mola polyculture system for a period of 172 days. Four stocking densities of Rohu were maintained as 500, 1,000, 1,500 and 2,000 ha -1 in treatment R500, R1000, R1500 and R2000, respectively in triplicates. All ponds each 120 m 2 were stocked with juvenile fr...

The green tiger shrimp (Penaeus semisulcatus) is an economically important species among native Iranian Shrimps. Microsatellite loci were developed for population genetic assessment of this species in Iranian waters. A total of eight polymorphic microsatellite loci were developed and tested on 40 individuals. The number of alleles per locus ranged from 5 to 12 with average of 7.38 per locus. Th...
