Leal Bordon José Roberto Kfoury Junior Biología Aquaculture Heat stress Fish health Heat shock protein Oncorhynchus mykiss In triploid fish physiology there is a lack of information about its molecular responses under stress and how to quantify the stress levels or intensity. Thus, the goals of this trial were to evaluate the pattern of HSP70 in the gills, heart and muscles of non-stressed diploid and triploid rainbow trouts, and in the blood cells after the exposure to heat stress in order to assess their stress levels. Similar HSP70 immunohistochemical detection in the gills, heart and muscles samples was seen in both ploidies. However, HSP70 expression in blood varied between ploidies over the experimental time. Control and stressed diploid trouts showed analogous HSP70 levels, but heat stressed triploid trouts showed lower HSP70 levels throughout the experiment with differences observable after 12h and 24h. It was expected higher HSP70 expression in both ploidies once this protein protects the cells against a wide range of disturbing agents. Recent evidences showed that triploid fishes have lower gene expression and this fact must be explored in future investigation in rainbow trouts. In conclusion, comparisons over time between diploid and triploid HSP70 levels in trouts could be used in stress evaluation and welfare statement. 2022 artículo científico 2737-6095 https://www.redalyc.org/articulo.oa?id=722479694004 en http://www.redalyc.org/revista.oa?id=7224 AquaTechnica application/pdf Universidad Técnica de Manabí AquaTechnica (Ecuador) Num.1 Vol.4 |
