{"title":"Tilapia Fish Farming Assessment using Water Wells in Fayoum and Egypt: Case Study","authors":"Emad Fawzy, Mohamed Nower, S. A. Elella","doi":"10.21608/ijsrsd.2022.273927","DOIUrl":"https://doi.org/10.21608/ijsrsd.2022.273927","url":null,"abstract":"According to the importance of fish farming in Egypt, this research was initiated with the objective of studying the parameter effected on economics of fish farming using water wells under several Egyptian conditions. In the primary phase of the study, the literature in the field of fish farming was assembled, reviewed, analysed, and categorized to deduce data about fish farming locations and to analyse such data. The research problem definition is concentrated in the lack of quantities of fish availability in Lake Qarun. Methodology is to identify many different variables such as the influence of environmental factors, water availability and water quality, the physical and chemical properties of water, climatic factors, fish death conditions, and weather in order to achieve the research objectives, which are to provide fish farming using surface well water as an accepted water quality for fish farming, to consider the soil as a filter for water and study the water quality from wells. This study was undertaken in Shakshouk Research Station of Fayoum governorate in Egypt during 2020 to 2022 to assess and evaluate the Tilapia Fish Farming Assessment using Water Wells in Fayoum governorate in Egypt. Based on the investigation outcomes, it was concluded that total direct and indirect cost comprised the capital and variable items of Egyptian pound (EGP). The cost of producing one kilogram of Tilapia fish was 25.4 EGP, and the selling price was 30 EGP for each kilogram of fish with markup including profit, risk contingency, financial charge, and market requirements for supply and demand all these items was estimated 4.6 EGP. This indicates that fish farming is a good way to take advantage of the enormous supply of water in the research station, and that it could be a substantial source of income in the case of increasing the awareness of regional people and an allocating a suitable market in the area.","PeriodicalId":137669,"journal":{"name":"International Journal of Sustainable Development and Science","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127946433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soft rot is most common throughout field production and storage. Our research study was aiming to analyse peroxidase and polyphenol oxidase, catalase, and phenol production in the infected potato Sponta and Mondial cultivars with Pectobacterium spp in response to 5 mM of glycyrrhizic acid ammonium salt, salicylic acid, and composites in the normal and nanoform treatments. The obtained results showed that Peroxidasee activities in potato leaves increased to the highest level of 3.9 U.ml -1 in Mondial cultivar in response to 5 mM SA NPs compared to 0.73 U.ml -1 in the positive control and 0.47 U.ml -1 in the negative control.

These conventional acaricides are cheap and easy to apply, but prolonged use causes Varroa mites to rapidly develop resistance, and bee products can become contaminated with residues of acaricides. The bioassay test was used to detect acaricides toxic effects. Spirodiclofen and Spiromesifen were the most toxic compounds to honeybee worker with LC 50 values of 0.923 and 1.195 ug/ml, respectively, after 5 days, but Amitraz, Chlorfenapyr, and Abamactine were the least toxic compounds to honeybees with LC 50 values of 1.752, 42.72, and 56.868 ug/ml, respectively, after 5 days. Amitraz, Spiromesifen and Spirodiclofen were the most toxic compounds on V. destructor with LC 50 values of 0.497, 0.888 and 2.014 ug/ml, respectively, after 4 h, but Abamactine and chlorfenapyr were the least toxic compounds on V. destructor with LC 50 values of 70.972 and 76.62 ug/ml, respectively, after 3 h. Varroa mite infestation rates decreased in brood (75.5% vs 67%) and adult honeybee workers (77.16% vs 100%) of colonies treated with Spiromesifen and Amitraz, respectively, when compared to only non-treated colonies.

In addition to its effect on the vegetative characteristics of pomegranate , and the rates of both peroxidase (PO) and polyphenol oxidase (PPO) enzymes in the roots of the pomegranate plants.

As well as binary treatments led to increase peroxidase and polyphenol oxidase enzyme rates by (10.3 and 9.5%) respectively, compared with control.
