Studies on Spatial and Seasonal Variation of Water Quality and Fish Species Diversity in the Man stream, Shivalik, Himalayas, India Using the ArcGIS Mapping System
Bibliographic record
Abstract
The present study assesses the water quality of the Man stream, a significant tributary of the Beas River in Shivalik Himalayas, Himachal Pradesh, by analyzing environmental variables, Water Quality Index (WQI) and fish species distribution using the Geographical Information System (GIS). Water samples were collected from two sites (upstream and downstream), over a year and various physiochemical parameters were analyzed. The study utilized the Canadian Council of Ministers of Environment - Water Quality Index (CCME-WQI) to evaluate water quality, depicting "fair" to "marginal" water quality status. Pearson’s correlation coefficient was used to assess the correlation between physiochemical parameters. A total of 23 fish species belonging to 6 orders and 9 families was reported, with Cypriniformes being the dominant order. Diversity indices revealed seasonal variations in fish communities, with the highest dominance index during monsoon and the Simpson and Shannon indices lowest during monsoon and nearly the same during pre-monsoon and post-monsoon with insignificant fluctuations. This comprehensive assessment provides valuable insights for fishery management and sustainable development in the region.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
