AN ECONOMIC STUDY FOR PRODUCTION AND CONSUMPTION OF FISH IN EGYPT

The Fisheries is considered an important source of national income. Fish product is one of important component in the agricultural production. the problem of this study determined in increasing fish food gap with about 319 thousand tons in 2012. The study aimed to description and analysis of fish production in Egypt in terms of domestic production, imports, exports, consumption, the food gap, the proportion of self-sufficiency, the average per capita available amounts for consumption, In addition, studying the factors that effect on the production and consumption of fish in Egypt. The study should be verification the following results The fish production in Egypt is growing annually by about 55.9 thousand tons during the period average (1995-2012), which represents about 6.4% of the annual average, Imports of fish increase during the study period by about 4.5 tons by about 33.6 million pounds per year, and fish exports are increasing annually by about 0.68 tons by about 5.3 million pounds annually while the production of fish according to different sources show that fish farming ranked first by about 55.3% of the average amount of production, and the total northern lakes ranks second at about 14.7%, while the production of the Sea (White, Red ) ranked third by about 14.1%, and the River Nile is ranked fourth by about 10.2 and inland lakes and coastal ranked fifth and sixth by about 5.2%, 0.5% respectively during the study period . Nevertheless, the results show that there are statistically significant differences between the indicators during the period average (2008-2012). In addition, the results show that tilapia ranked first with an average production of about 646.4 thousand tons representing about 52.1%, While the average production of mullet, carp, catfish, reaches about 181.9, 142.1, 43.1 thousand tons respectively, representing about 14.7%, 11.5%, 3.5% respectively of the average total fish production during the period (2008-2012). The study also indicate that the most important economic factors that affecting on the fish production in Egypt is the amount of fish imports, the quantity of available fish, the partial elasticity of them are about -0.294 and 1.2, which indicates that an increase in the quantity of imports by about 1% leads to the decline of fish production by about 0.3%, increase the amount of fish consumption by about 1% lead to increase the amount of production by about 1.2%. However, the results show that the most important factors affecting on the amount of fish consumed in Egypt is the population and the average price of a kilogram of fish. Therefore, the study recommended the development of fisheries sector and set up of collection centers for the production of fish near fish farms, Moreover, the necessity of expansion in aquaculture to fill the fish food gap.

Fish Consumption in Infancy and Asthma-like Symptoms at Preschool Age

To assess whether timing of introduction of fish and the amount of fish consumption in infancy were associated with asthmalike symptoms at preschool age. This study was embedded in the Generation R study (a population-based birth cohort in Rotterdam, Netherlands). At the age of 12 and 14 months, timing of introduction of fish into the infant's diet was assessed. The amount of fish consumption at 14 months was assessed by a semiquantitative food frequency questionnaire. Presence of asthmalike symptoms in the past year was assessed at the child's age of 36 and 48 months. Relative to no introduction in the first year of life, introduction between age 6 and 12 months was significantly associated with a lower risk of wheezing at 48 months (odds ratio [OR]: 0.64; 95% CI: 0.43-0.94). When compared with introduction between 6 and 12 months, no introduction in the first year and introduction between 0 and 6 months were associated with an increased risk of wheezing at 48 months (OR: 1.57; 95% CI: 1.07-2.31 and OR: 1.53; 95% CI: 1.07-2.19, respectively). The amount of fish at age 14 months was not associated with asthmalike symptoms (P > .15). Introduction of fish between 6 and 12 months but not fish consumption afterward is associated with a lower prevalence of wheezing. A window of exposure between the age of 6 and 12 months might exist in which fish might be associated with a reduced risk of asthma.

Fish consumption in pregnancy, cord blood mercury level and cognitive and psychomotor development of infants followed over the first three years of life: Krakow epidemiologic study

BackgroundAlthough the maternal fish consumption is supposed to have beneficial effects on development of infants, it may be harmful for child cognitive development since fish is a common source of methylmercury. Purpose of the studyPurpose of the study was to describe the usual pattern of fish consumption during pregnancy in Poland and explain the variability of prenatal mercury exposure due to fish intake by mothers. The other endpoint of the study was the assessment of the cognitive and psychomotor development of infants related to prenatal mercury exposure over the 3-year follow-up. Material and methodsThe study sample consisted of 374 infants born at 33–42 weeks of gestation between January 2001 and March 2003 to mothers attending ambulatory prenatal clinics in the first and second trimesters of pregnancy. Total mercury level in whole cord blood was measured and the Bayley Scales of Infant Development (BSID-II) was used to assess the mental (MDI) and psychomotor developmental index (PDI) in children at 12, 24 and 36 months of age. ResultsSelf-reported weekly amount of fish consumption during the first two trimesters of pregnancy correlated positively with umbilical cord mercury concentrations (rs=0.22, p<0.0001). The corresponding correlation coefficient for the fish consumption in the third trimester of pregnancy was 0.21, p<0.0001. There was an inverse association between mercury exposure and both MDI (beta regression coeff.=−2.8, p=0.01) and PDI scores (beta coeff.=−2.3, p=0.04) at 12 months of age. Subsequent BSID-II testing at 24 and 36 months did not confirm significant association between exposure and cognitive or psychomotor function. The estimates of association between mercury prenatal exposure and the development of infants, which were based on the longitudinal analysis of all BSID-II measurements done in the follow-up (generalized estimating equations statistical model) showed that the performance deficit observed at 12 months of age was of border significance.

Fish Consumption and Mortality from All Causes, Ischemic Heart Disease, and Stroke: An Ecological Study

Background.The present study examined the relation between fish consumption and mortality from all causes, ischemic heart disease, and stroke.Methods.The fish consumption data in 1961–1963, 1979–1981, and 1989–1991 and mortality data, age-standardized to 45–74 years, mean of the latest available 3 years, mostly around 1992–1993, in 36 countries, were obtained from the Food and Agriculture Organization and the World Health Organization, respectively.Results.There exists an inverse univariate correlation between log fish consumption in 1961–1963, 1979–1981, and 1989–1991 and log all-cause (P< 0.01 to < 0.001) and ischemic heart disease (P< 0.05 to < 0.01) mortality in both sexes. An inverse univariate correlation between log fish consumption and log stroke mortality was found only for the period 1961–1963 in both sexes (P< 0.05). Log fish consumption was independently, significantly, and inversely associated with log all-cause (allP< 0.001), ischemic heart disease (P< 0.01 to < 0.001), and stroke (P< 0.05 to < 0.001) mortality in all three time periods in both sexes, after adjusting for confounding factors. These associations remained significant even after exclusion of Iceland and Japan, countries with the highest amount of fish consumption and the lowest all-cause mortality rate.Conclusions.Fish consumption is associated with a reduced risk from all-cause, ischemic heart disease, and stroke mortality at the population level.

Difference by sex and age of mercury concentration in red blood cells

The mercury concentration in red blood cells (RBCs) is one of the most useful indicators for people exposed to methylmercury. Sex- and age-related differences in mercury concentrations in red blood cells were studied by considering fish consumption in 1,253 adults (511 males and 742 females) participating in a mass health examination conducted in a town of Kumamoto Prefecture in 1989. The results were as follows: 1. The mercury concentrations in RBCs showed lognormal distributions for both sexes with a higher mode in males than in females. The geometric mean of the mercury concentrations in the RBCs was 28.5 ng/g (ranging from 5.6 to 71.0 ng/g) for males and 20.4 ng/g (ranging from 3.7 to 70.4 ng/g) for females and was significantly higher in males than in females. The mercury concentration in RBCs decreased with aging for both sexes. 2. The mercury concentrations in RBCs significantly increased with the amount of fish consumption for both sexes. The mercury concentrations in RBCs were significantly higher in drinkers than in non-drinkers for males and the concentrations increased significantly with body weight for females. 3. The mercury concentrations in RBCs were higher in males than in females and decreased with aging for both sexes under conditions of a constant level of fish consumption. 4. In couples who consumed same amount of fish, the mercury concentrations in RBCs were significantly higher in husbands than in wives. These results suggest that the mercury concentrations in RBCs are higher in males than in females and decreases with aging under a constant level of fish consumption.

Interrelationships among hair mercury levels, fish-eating habits and fatty acid composition of serum lipids

Scalp hair and blood samples were collected from 151 persons who were living in several places in Kagoshima-prefecture and supposedly had no abnormal exposures to mercury compounds. Hair was analysed for total mercury and blood was analysed for serum lipid fatty acids. The study subjects were also individually questioned on the amounts of average fish intake in a day. Results obtained were as follows:1) Hair mercury levels were significantly higher in males than in females, the average values being 11.95±9.15ppm with a maximum of 45.5ppm for males and 7.05±5.36ppm with a maximum of 25.8ppm for females. The hair mercury levels increased with increases in the amount of daily fish consumption for both sexes with an indication that such increases might be attributable to the fish consumption.2) Serum concentrations of eicosapentaenoic acid (20:5, EPA) and docosahexaenoic acid (22:6, DHA) both of which belong to the ω-3 series of polyunsaturated fatty acid, and the value of EPA/AA (a ratio of 20:5 for arachidonic acid) also increased with an increase of daily fish consumption for both sexes, indicating that these values can give quite valuable information in the assessment of individual fish consumption.3) When comparison was made taking into account of the amount of daily fish consumption, however, there were no significant differences of hair mercury levels between the sexes, particularly for those having a low intake of fish.4) There were no significant differences between the sexes for the serum concentrations of eicosapentaenoic acid and docosahexaenoic acid but the value of EPA/AA was significantly higher in males than in females, suggesting that males have a partiality for a fish diet as compared with females.5) When the serm concentration of eicosapentaenoic acid or docosahexaenoic acid was used as an indicator for evaluation of the amount of fish consumption, the hair mercury levels showed a tendency to increase along with the values of these indicators for both males and females. However, the hair mercury levels were significantly higher in males than in females even when the comparison was made taking into account of the values of these indicators, which could not be explained only by the amount of fish consumption.
