Study on Effect of Fibrolytic Enzymes Supplementation on in vitro Gas Production Kinetics and Ruminal Fermentation of Date Palm (Phoenix dactylifera) By-Products | Chapter 6 | Research Aspects in Agriculture and Veterinary Science Vol. 3

 One of the suggested stunning methods that is consistent with animal welfare is electric field exposure during fish harvesting at an aquaculture farm or sample site. The goal of this study is to examine the microbiological and psychochemical quality of climbing perch that have been electroshocked for 2 minutes at 50, 70, 90, and 110 volts, with controls kept untreated. After being stunned at 70-90 V, the bacteria count in climbing perch decreased dramatically (p0.05). Meanwhile, stunning at 50 and 110 V did not differ significantly from the untreated samples (p>0.05). The pH value in climbing perch was not significantly affected (p0.05) by stunning at 50-110 V. Climbing perch stunned at 90-110 V had a considerably (p0.05) reduced quantity of overall colour than untreated samples, giving the fish flesh a pale appearance and discolouration. Electric field exposure for fish harvesting is recommended at 70-90 V, which considerably reduces microbial impacts while causing minimal aesthetic changes.
