abstract

in order to improving suitable growing condition for cultured species, knowledge of energy yieldingnutrients, especially information about carbohydrate requirement are of oriental river prawn isessential, since there is not exclusive studies about carbohydrate requirement about this species, hencean nutritional experiments was conduct in order to find out the optimum level of carbohydrate. fivetreatments with levels 15, 20, 25, 30 and 35 percent with iso- nitrogenous (35%) and iso- lipidic(8.5%) we formulate each treatment was conducted in triplicate. two hundred and twenty five juvenileprawn (of size 1.5±0.33g) were randomly distributed between 15 aquarium tank of 200 l capacity.the juvenile prawns which fed diet containing 30% carbohydrate were shown optimum condition ingrowth indices and was significant with other treatments (p0.05):however, treatments 1 & 5 had higher amount of moisture ,with lower amount of protein and lipidvalue in their body composition (p

Growth performance, feed efficiency and whole-body chemical composition of the oriental river prawn, Macrobrachium nipponense, fed different dietary protein to lipid ratio

A 56 days grow-out experiment with three protein levels (35, 40 and 45%) and three lipid levels (5, 10 and 15%) was conducted to evaluate the optimum protein to lipid ratio for oriental river prawn (Macrobrachium nipponense). Four hundred and five prawns, with mean (± SD) weight of 1.40 ± 0.04 g were distributed in 27 glass aquaria and were fed four times daily. Results showed tha...

Effect of thermal shocks on survival and safety responses of oriental river prawn, Macrobrachium nipponense (De Haan, 1849)

This study was performed to determine the severity of hormonal changes and the immune system of oriental river prawn (Macrobrachium nipponense) in the face of thermal stresses (heat and cold). For this purpose, 80 pieces of prawn with an average weight of 1.5 ±0.3g were prepared from Anzali wetland and in the laboratory after a rest period, under thermal stresses (from 15 ° C to 22 ° C) and col...

Effects of Host Phylogeny and Habitats on Gut Microbiomes of Oriental River Prawn (Macrobrachium nipponense)

The gut microbial community is one of the richest and most complex ecosystems on earth, and the intestinal microbes play an important role in host development and health. Next generation sequencing approaches, which rapidly produce millions of short reads that enable the investigation on a culture independent basis, are now popular for exploring microbial community. Currently, the gut microbiom...

Genetic diversity analysis of oriental river prawn, Macrobrachium nipponense, in Yellow River using microsatellite marker.

To assess the genetic status of this species, the genetic diversity of wild Macrobrachium nipponense from seven geographic locations in the Yellow River basin were investigated using 20 polymorphic microsatellite DNA loci. The genetic diversity between populations was indicated by the mean number of alleles per locus and mean observed heterozygosity (H) and the expected H, which was arranged fr...

Insights into Sexual Precocity of Female Oriental River Prawn Macrobrachium nipponense through Transcriptome Analysis

BACKGROUND The oriental river prawn (Macrobrachium nipponense) is the most prevalent aquaculture species in China. The sexual precocity in this species has received considerable attention in recent years because more and more individuals matured at a small size, which devalues the commercial production. In this study, we developed deep-coverage transcriptomic sequencing data for the ovaries of ...
