Use of modern geometric design of fish ponds to increase welfare and blood parameters

Abstract

Fish currently suffer from a lack of well-being due to the large number of pollutants in the water and the lack of space given to them, which makes them afraid and uncomfortable, which leads to a lack of welfare and, thus, a lack of production and poor quality of meat. This study was designed using a modern geometric design (DGD) of basin design, which is an H-mark. Three hundred fishes were used and distributed in three treatments with four replications; each treatment consisted of 100 fishes, and each replicate included 25. The first treatment was a control treatment (C), represented by raising fish in regular ponds, and the second treatment was fish farming using novelty design ponds in the shape of the H sign (ND). The third treatment was the fish farming treatment in earthen ponds (EP). The statistical analysis findings demonstrated that the ND treatment significantly improved the condition. ( p≤0.05) in the number of red blood cells, over the rest of the treatments, and significantly ( p≤0.05) for HD hemoglobin, was superior to the rest. In PCV, the ND treatment was a significant improvement compared with the rest of the treatments if the highest value was recorded, the results demonstrated significant changes between the experimental treatments at the level (p 0.05). The outcomes revealed that the number of white blood cells significantly increased with ND therapy (p 0.05). Cells, over the rest of the treatments, and a significant improvement ( p≤0.05) for H/L compared with the rest of the treatments; there were no significant differences between the experimental treatments, but there was a significant improvement ( p≤0.05) in ND treatment in the Glucose, cholesterol, triglyceride HDL, LDL, GPT, and GOT, over the rest of the treatments. Using a novelty design in the ponds helped the fish increase their well-being due to their feeling of comfort and lack of fear, which improved their behavior, blood traits, and growth performance.
