AI Article Synopsis
- The study aimed to determine the best water temperature for breeding juvenile Paralichthys olivaceus in biofloc.
- Findings showed that temperatures above 28 °C led to significant decreases in hemoglobin and hematocrit levels while increasing several plasma components like calcium and glucose.
- Temperatures over 26 °C caused hematological changes and oxidative stress in the fish, suggesting that higher temperatures induce thermal stress.
Article Abstract
The purpose of this study was to ascertain the optimum water temperature for breeding juvenile Paralichthys olivaceus in biofloc. Hemoglobin and hematocrit were significantly decreased when the temperature was higher than 28 °C. Plasma calcium, glucose, cholesterol, glutamic-oxaloacetic transaminase, and glutamic pyruvic transaminase were significantly elevated at high temperatures, whereas total protein was substantially lower. Superoxide dismutase and glutathione-S-transferase activities in the liver and gills were significantly elevated at high temperatures, whereas glutathione was significantly lower. This indicates that temperatures greater than 26 °C induced hematological changes and oxidative stress in the juvenile P. olivaceus in biofloc. We ascribe these changes to thermal stress.
