After reviewing the descriptive and statistics analysis along with the non-parametric statistics, the fish consumption per capita was extracted through formulas. The average and mode of purchasing of each household occurs 11 times per year with 5.1 Kg in each time . Considering the higher fish consumption growth rate in Iran, the sequence of interest in all kinds of protein is as follows: poultry, mutton, beef, Trout, wild fishes and Chinese carps. The highest interest of households to buy fish more than other protein resources is due to the nutrient value of it. An average of 33.2% purchasing is dedicated to the farmed fish. 59% of purchasers are interested to buy packed up fish products and pay attention to the label of nutrient values on the product package. Fish consumption per capita is 13.3 Kg, which is divided to 6.4 kg for farmed fishes, 5.8 Kg for wild fishes and 1.1 Kg for canned fish. The higher consumption per capita of Tehran citizens in comparison with other people from other cities, who are living in Tehran, is because of their tendency and freshness of farmed fishes.   In contrast, the consumption of canned and wild fishes among people of littoral regions who live in Tehran is higher than others.}, Keywords = {Fish consumption per capita, Fisheries, Tehran, Iran}, volume = {10}, Number = {4}, pages = {546-556}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-265-en.html}, eprint = {http://jifro.ir/article-1-265-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2011} } @article{ author = {Akbary, P. and Hosseini, S.

Four microsatellite loci ( Ls 68 , Spl 168 , Spl 173 and Afu 68 ) were analyzed for the molecular characterization of this species which resulted in polymorphic patterns. DNA bands were analysed using Biocapt and GenAlex software package. A total of 109 alleles were observed of which the maximum number of alleles (17) were found in Spl168 locus which belonged to sturgeons from Sefidrud river,s watershed and the minimum number of alleles (10) in Ls68 locus belonging to the sturgeons from Gorganrud river,s watershed. Results of microsatellite analysis revealed that the differences between samples of two regions were not statistically significant (p>0.05), neither for the average number of alleles per locus nor for observed heterozygosities. The calculated Fst and Rst between two regions was 0.07 and 0.17 showing that the genetic difference was significant (p< 0.01). Samples from Sefidrud river,s watershed in Spl173, Afu68 and Spl168 loci and samples of other regions in Afu68 and Spl168 loci were at Hardy-Weinberg equation. The genetic distance was calculated as 0.4 which represents a significant genetic difference between samples of two studied areas.

Using wild common carp in aquaculture is limited for uncontrolled variation in performance of fish derived from undomesticated breeders. A 7×7 factorial mating design was employed to examine genetic effects of dam and sire on growth and heritability of growth-related traits based on dam half-sib and sire half-sib families. Breeders were obtained originally from the Caspian Sea. A total of 1470 offspring were raised in 49 separate fiberglass tanks with common conditions. Body weight and length were recorded at three different ages of rearing. Estimation of heritability of weights ranged from 0.23±0.05 to 0.30±0.07 for dams and ranged from 0.15±0.03 to 0.26±0.04 for sire. Similar results were obtained with length but with less variation (0.24±0.02 to 0.26±0.01 for dams and 0.20±0.02 to 0.22±0.03 for sire). The broad-sense of weight and length are 0.23±0.04 and 0.23±0.01 respectively. The dam and sire effect on growth were significant, indicating the presence of variations among the native fish of the Caspian Sea. Therefore, it is suggested to use a length for selection that is more reliable and less affected by environment than weight at any time of growth and in respect of high phenotypic correlation (0.87-0.95) observed between weight and length. In the present study we even used wild common carp and the heritability was not higher than the domesticated common carp. It means the genetic variation for quantitative traits, for common carp of the Caspian Sea are low or it may be under pressure of inbreeding which should be studied further.}, Keywords = {Caspian Sea, Common carp, Heritability, Genetic Parameter}, volume = {10}, Number = {4}, pages = {740-748}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-281-en.html}, eprint = {http://jifro.ir/article-1-281-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2011} } @article{ author = {Jalali, S.
