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.

Some histological effects of Bisphenol-A on some reproductive organs in male adult rabbits (Oryctolagus cuniculus)

“…It could also cause an increase in Prolactine gene expression and release, 12,13 . The recent study exhibited the disorganization of seminiferous tubules of BP-Treated rabbits with germinal epithelium sloughing; those outcomes were granted with 14 findings attributed to the increasing smooth muscle movement because of the inflammation that affects the epithelial tissue responses and then causing disproportionate stretch of the epithelial lining, through the release of chemotactic substances 8 . In the current study, results explained a dis-organization of the epididymal tubules with cellular hypertrophy of the BP-A-A treated rabbits, the shape of the epithelial layer was conformed from columnar to flat; the results were in contract with 18 results, who related the cause to the defense mechanisms toward the exposure to the BP-A forging substance.…”

“…Histological examination of the prostate sections of BPA treated Group (3) revealed a presence of hyperplasia with hemorrhage in the capsule of the prostate, which was elucidated by 22,24,25 , who stated that the prostate was sensitivity to the synthetic and natural estrogen hormones and altered the prostate development and differentiation. Seminal vesicles of the Group (3) that were treated with BPA showed thickness in the acini epithelium with congested blood vessels as elucidated by 8 , who stated that any injury of the male reproductive system can cause differentiation of cells by mitosis, and then growth of the new hyperplastic epithelium. These findings agreed with 23 , who stated that the oxidative stress in tissues also could be seen because of the exposure to BP-A through its changing the iNOS expression, which downregulated the expression of testicular androgens receptors.…”

“…However, this diverges with the findings of 17, who explained that serum testosterone levels do not alter, although BP-A could affect fertility. The decrease in LH levels might be caused by the reduced sensitivity of pituitary gonadotropene cells 10 , or low levels of testosterone may cause it via the antiandrogenic action of Bis-PA 8 . The decreased FSH level could be caused by 17 B-estradiol that inhibits the secretion of gonadotropins from the pituitary due to the estrogen mimic action, as documented by 11 .…”

The effect of spraying with amino acids and iron on some characteristics of vegetative and flowering growth of petunia

“…There are two forms of amino acids, the first of which is the free form (L-amino acids), which are absorbed and built from the plant. The second is D-amino acids, which do not participate in forming proteins, as they play a role in forming enzymes 11 . Amino acids have particular importance in stimulating and growing cells, and they serve as stores that help maintain pH inside the plant 12,13 .…”

Study protective role Camellia sinensis L. (black tea) and silver, Zn oxide nanoparticles on antioxidant-oxidant enzymes and biochemical level against paracetamol overdose in adult male rats

“…However, acute overdoses of paracetamol, whether accidental or planned, are relatively common and can be exceedingly dangerous. Adults may suffer severe hepatocellular necrosis if they consume 10-15 grams of paracetamol, and 20-25 grams are lethal 13 .…”
