CHARACTERISTICS OF PLANKTON COMMUNITY STRUCTURE IN THE FISH CAGE CULTURE AREA OF YONGJIANG RIVER
Bibliographic record
Abstract
Plankton is an important biological indicator for water quality assessment.In order to understand the water trophic status in the fish cage culture area of Yongjiang River,Nanning City of Guangxi Province,the population composition,quantity and dominant species of plankton were studied based on bimonthly sampling from September 2009 to September 2010.All data were collected from two sampling sites located between Jinling River and Qingchuan River,which was the main cage culture area in Yongjiang River.The results indicated that a total of 8 phyla and 98 species of phytoplankton were identified.The species numbers of Chlorophyta and Bacilla riophyta represented for 42.8% and 24.5% of total species richness.Four phylums and 44 species of zooplankton were identified,in which rotifer dominates 43.2%.In general,more plankton species were found in summer and autumn than that in winter and spring.The seasonal variations of plankton density and species number were identical.The comprehensive trophic level index (TLI) values were between 59.28 and 66.87,which means that the water quality in the fish cage culture area of Yongjiang River was in between mesotrophic and nutritious level.The Shannon-Wiener diversity varied from 1.35 to 1.56,while evenness indices from 0.2275 to 0.2586,it means that the relevant water quality was in between mesotrophic and nutritious level.The studies show that the water trophic status evaluation results of the fish cage culture area along Yongjiang River detected by TLI was consistent with that of the Shannon-Wiener diversity index and evenness indices.

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.
