Effect of Culture Conditions on the Levels of Serum Insulin-like Growth Factor-1 in Indian Major Carps
Bibliographic record
Abstract
The insulin-like growth factor-1 (IGF-1) plays an important role in the regulation of development and growth of fish. Aquaculture researchers consider it as a potential growth rate indicator. Reports on the IGF-1 of carps are limited. This study was undertaken to determine the serum IGF-1 levels of Indian major carps (IMCs) cultured in the normal pond, sewage-fed pond and captive conditions. Labeo rohita of the normal pond recorded the highest serum IGF-1 level (2.10±0.14 ng/ml), followed by Catla catla (1.99±0.17 ng/ml) and Cirrhinus mrigala (1.82±0.12 ng/ml). Captive held C. catla recorded the highest serum IGF-1 (2.10±0.19 ng/ml) compared to L. rohita (2.04±0.08 ng/ml) and C. mrigala (1.90±0.09 ng/ml). In the sewage-fed pond, C. catla, L. rohita and C. mrigala recorded the serum IGF-1 levels of 2.38±0.36 ng/ml, 2.06 ±0.03 ng/ml and 1.07±0.06 ng/ml, respectively. Significant differences existed among the serum IGF-1 levels of C. mrigala reared in the normal and sewage-fed pond as well as the captive and sewage-fed pond (P < 0.05). It appears from the results that C. catla and L. rohita are the ideal cultivable species under the sewage-fed aquaculture. The serum IGF-1 level may be an effective indicator of the differences in growth of carps.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
