| To study the relationships among tissues, organ weights, and body weight of tilapia (Oreochromis niloticus) and obtain organ coefficients, 40 adult male GIFT tilapia with body weights of 600~900 g were randomly selected, and their body weight and weights of the heart, liver, kidney, spleen, intestine, gill, skin, gallbladder, scales, muscle, and carcass (fish head, fins, and fish bones) were measured, as well as the total weight of each fish after dissection. Correlation analysis was performed on the body weight and organ weights of the various tissues, an optimal regression model was established, and model extrapolation was verified using approximately 500 g of tilapia tissue organ weights. The results showed that the organ coefficients of the heart, liver, kidney, spleen, intestine, gill, skin, gallbladder, scales, muscle, and carcass of GIFT tilapia were 0.12±0.02, 1.22±0.20, 0.11±0.03, 0.13±0.05, 1.58±0.30, 2.85±0.17, 3.31±0.38, 1.05±0.24, 2.89±0.41, 51.60±2.09, and 29.66±2.00, respectively, and all the measured tissue and organ weights and body weight were significantly positively correlated (P<0.001). This was consistent with the univariate linear regression model (y=bx) and the predicted error of the model for the heart, liver, kidney, spleen, skin, and muscle of the tilapia was within 8%. These results provide baseline data for fish physiology, toxicology, and the construction of a physiologically-based pharmacokinetics model for veterinary medicine of fish. |
