הוספת תג | סיכום: | At present there are a little more than 800 million people suffering chronic malnutrition in the world, it is also estimated that the population in the world increases by about 2 billion, and by approximately 2050 can reach about 9600 million. (FAO, 2014) In the 2014 edition of "The State of the World's Fisheries and Aquaculture", it is notorious that what is important for our planet in terms of food is fishery and aquaculture, not forgetting or leaving aside the work to improve the Global health and suppress poverty. (FAO, 2014) Some reports indicate that never before has the food and well-being of mankind been in the hands of or depended in such a way on the fisheries aquaculture sector as it now depends. The goods of the sea are a source of nutrients and proteins at low cost, and are an essential contribution, fundamentally for the most needy. (FAO, 2014) In our country fishing, whether industrial or artisanal and aquaculture, has provided us with both food and income for a long time. In the province of El Oro, aquaculture is one of the areas with the most foreign exchange generated, and has provided employment to entire families. In one of the tests carried out in the present work, the results show that the laboratories Genesis (3,040,67 lbs / Ha) and Nutriagro (2,980.60 lbs / Ha) obtained better results in relation to Biomass or final production, the Which show significant statistical differences with Reydamar (2,163.80 / Ha), Doblet (2,497.00 lbs / Ha) and Acualab (2,601.00 lbs / Ha), which may be associated with the fact that in the Labs Nutriagro and Genesis maintain More sophisticated production processes or, in its absence, better control of all processes. Duncan's multiple range test showed that in the laboratories of Genesis (68.33%), Doblet (67.67%) and Nutriagro (62.8%), where larvae come from (49.6%) and Acualab (55.4%), which may be associated with the fact that in the Genesis, Doblet and Nutrtiagro Labs, A more technified larval production process or, in its absence, a better control of all the processes. Once the correlation between the food conversion variable and the biomass or final production is obtained, a correlation coefficient (r = 0.567) is obtained, which shows a moderate positive relation. The R² obtained from 0.322 indicates that 32.2% of the total variability of the final Biomass is explained by the feed conversion (Table 10). As shown by the statistical results obtained and as shown in Figure 5, the incidence of feed conversion on the biomass or final production is indirect, since the greater the conversion, the lower the production, and an inverse relation is the Dispersion shows the line that best fits the proposed model and gives the equation y = 3.95E3 + -8.34E2 * X, which would serve to predict the values of the final biomass depending on the changes occurring in The feed conversion of shrimp. |
