Results revealed that although the average values of physio-chemical and bacteriological parameters were within the acceptable limits at water inlets in examined farms; a great variation were recorded among both Farms and ponds within the same farms as water in ponds of farm (IV) showed a significant increase in the measurable parameters P \u0026lt;0.05 with a significant decrease in dissolved oxygen followed by pond 2 in farms (III) and (I) respectively (3.6±0.7, 4.9± 0.61 and 6.5±0.31 mg\/l). Meanwhile farm (II) showed a significant decrease P \u0026lt; 0.01compared with other examined farms. Faecal coliforms were isolated from water ponds and fish in farms I, III and IV (1.0±0.12, 5.02±0.5, 14.0±3.6 and 23.0± 4.3\/ 100ml) \u0026amp; (0.4±1.5, 1.6±1.5, 4.0 ±1.0, 10.8±1.2, 10.6±3.0 and 12.0±3.2 respectively).\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659872457\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659872457","offer_id":39435464507485,"sku":"9783659872457","price":54.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/fe0d0c73-63a3-4abe-88fc-4c0b00641881.jpg?v=1770789705","url":"https:\/\/shop.autorenwelt.de\/products\/evaluation-of-water-quality-in-fish-farms-its-effect-on-performance-von-asmaa-mohammed","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
