Researches Regarding Serum Biochemical Parameters as an Indicator of Fish Welfare in Two Farms from the Southern Area of the Country

摘要

The present study aims the assessment of fish welfare in two farms from the southern area of Romania (Ulmu and Ciocanesti) using as objective welfare indicator the serum biochemical profile. The tests were conducted by using Vettest 8008 Chemistry, being analyzed: blood urea nitrogen, creatinine, phosphatemia, calcium, albumine, cholesterol, glucose, total proteins, blood ammonia, alanine transaminase, aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase, total bilirubin, creatin kinase, triglycerides, amylase. The obtained results were compared with those from other scientific researches regarding carp serum biochemical profile. The values in Ciocanesti ponds show increased creatinine, aspartate aminotransferase, phosphatemia, lactate dehydrogenase, alkaline phosphatase values and a slightly increased calcium and albumine values, the cause being the dehydration and the intense muscular effort associated with fish angling and restraining. In Ulmu ponds, there is noticed in adition a significant increasing of cholesterol, transaminases and glucose, which could suggests hepatopancreatic disorders. Following the researches, the fish welfare level was acceptable in Ciocanesti farm and poor in Ulmu.
