Auteur(s): TOUMI I; ADAMOU A; BECILA S Résumé: In order to understand the place of sandfishmeatcompared to other sources of animal protein. A survey of the sale and consumption of thisanimalwascarried out among 994 respondents, aged 32 years on average, Come fromvarioustributaryorigins. The resultsrevealedthatskunkmeatwas a very important part of the diet of Sufi households. Half of the consumersreportedconsumingmeatof sandfish as a substitute for meat, a cheaper and sometimes free source of protein. 25% for its gustative qualityeven in the presence of meat and 20% for itstherapeuticvirtues. The live animal generallyrepresents the mostcommonform of sale during the summerperiod. On the other hand, a relative increase in the driedformisknown in autumn and winter. The gender distribution of purchasesisequal (23%). The purchasepriceissignificantlycorrelated ** (p˂0.01) with the season of the hunt and the form of sale.

This study allowed the identification of 52 families of arthropods distributed in 10 orders and 2 classes. A total of 397 individuals are counted including, 191 individuals are trapped by pitfall traps, 113 individuals by sweeping net and 93 individuals by yellow traps. Insects (96.1%) accounted for the largest share of arthropods recorded, with percentages varying according to sampling methods between 91.6% (pitfall traps) and 100% (sweeping net). On the other hand, arachnids (3.9%) are poorly represented, with percentages varying between 0 (sweeping net) and 8.4% (pitfall traps). Formicidae are heavily contacted, often accompanied by other winged groups such as the Aphididae, Scoliidae and Muscidae. This mixture constitutes a relatively large diversity (H '= 4.51 bits) in this type of area, whose individual numbers tend towards equilibrium (E = 0.79).

The management of these wastes and their disposal therefore becomes an obligation. The present work falls within the context of the management and valorization of solid urban waste. The recycling of household waste by composting is currently considered one of the components of sustainable development. To better control the composting process, the impact of microbial flora on physico-chemical parameters during the composting of household wastes on a pilot scale in a bioreactor was studied. The results obtained showed that the microbial flora modifies the physico-chemical parameters (T °, moisture, pH and released gases) during the transformation of the organic fraction of the solid waste within 60 days and the final compost obtained was satisfactory for its agricultural application.

The management of PWW derived from the basin of Ouargla aims, to medium term, the mobilization of these waters for irrigation. In the short term, almost all of these PWW is rejected in nature. Informal reuse in irrigation in some sites has been detected. The receiving environment of the PWW is « Sebkhat Safioune », it‟s an isolated area of about 10.000 ha located approximately at 40 km north of the city of Ouargla. The site of reuse most represented is a few hundred meters to the north of treatment station of Ouargla, it contains more than twenty plots irrigated with PWW and mainly planted of date palms, the PWW reuse in this site is neither organized nor controlled. PWW rejection has created ecological changes in the receiving environment previously barren, generating a water area of about 600ha, installation of flora and birdlife, rising water table and accumulation of wet organic matter are the main impacts observed. On the other hand in the reuse site, irrigation with PWW led to the rise of ground water. Description: Revue des BioRessources 2016-12-01T00:00:00Z
