“…In the present study, the contents of moisture and ash were found to be slightly higher in male prawns than that of the female prawns. It has been reported that the muscle of male prawns contained higher levels of ash and water, and the females have relatively greater amounts of fat, protein and carbohydrates (Amer et al 1991). It has also been reported in fish that the moisture content in the case of male was higher when compared to that of female both in winter and summer seasons (Nargis, 2006).…”

The proximate composition of biochemical constituents was analyzed in the muscle of adult male and female prawns of Macrobrachium rosenbergii collected from two different natural culture sites. This was in the order of moisture > protein > amino acids > carbohydrate > nucleic acids (RNA > DNA) > lipid > fatty acids > ash. The prawns collected from both natural culture sites showed reasonably good proximate composition. This indicates that the wild has provided adequate food source to the prawns. The proportion of total protein, amino acids, lipid, fatty acids, carbohydrate and RNA were found to be higher in female prawns than in the males. In contrast, the proportions of moisture and ash contents were higher in male prawns when compared with females. The level of DNA was found to be unchanged in both male and female prawns. HPTLC analysis of amino acids revealed higher levels of essential amino acids, such as phenylalanine, leucine, tyrosine, isoleucine, tryptophan, methionine, valine, threonine, arginine, histidine, lysine in female prawns when compared to the male prawns. Similarly, GC analysis of fatty acids showed both polyunsaturated and saturated fatty acids levels were found to be higher in female prawns when compared to the males. The variation in muscle constituents between male and female prawn reflects the differences in sex development and their energy requirements for body maintenance during the adult stage. In the present study, nutrition wise, the adult female prawn was as good or better

“…Concerning the results in Table 5, Jacquot [16] reported lower moisture but higher fat, protein and ash content for the crustaceans. Comparing the achieved results with those recorded for the Egyptian Prawn muscles (Paenus japonicus) by Amer et al [2], it was found that examined Procambarus clarkii samples contain more moisture and protein but less fat and ash.…”

Fresh water crayfish Procambarus clarkii which recently appeared in River Nile and its resources all over Egypt was microbiologically and chemically evaluated in order to determine its safety and quality as human food. The average aerobic plate and Enterobacteriaceae counts/g were 1.6 x 10(8) and 3.5 x 10(5), and the coliforms and E. coli were isolated from 100% and 40% of the examined samples respectively. However, Salmonellae could not be isolated from any of the examined samples. 20% of the samples were safe for human consumption, while 33.33% were marginally acceptable and 46.67% were unacceptable. The mean gross weight, yield of meat, moisture, fat, protein, ash and caloric values were 27.71 g, 12.37%, 82.19%, 0.59%, 15.6%, 1.51% and 283.3 KJ (67.71 Kcal) respectively. Recommended rules for its safety were mentioned.

“…Crustaceans particularly those of commerical values, have high ratios of total protein than carbohydrates and total lipids (Warner, 1977;Amer et al, 1991;Hashem, 1992;Abd El-Reheem, et al 2003).…”

“…The total lipid is generally low in crustaceans (Warner, 1977;Amer et al, 1991;Hashem, 1992;El-Zawahry et al, 1997;Abd El-Reheem, et al 2003). Cholesterol is one of the most important constituents of lipids in haemolymph of crustaceans and is the basic constituent of sex hormones (Highnam & Hill, 1979).…”
