An Evaluation of Goldeye Life History Characteristics in Two Kansas Reservoirs
Bibliographic record
Abstract
Abstract Goldeye Hiodon alosoides are native through much of Canada and the Mississippi River drainage in the United States. Life history characteristics have been described for several commercially important populations in northern portions of their range, but there is a paucity of information available for more southernly populations. Milford and Lovewell Reservoirs are in the Kansas River basin and harbor the only two lentic Goldeye populations in Kansas. Further, anecdotal observations suggest declining population abundance. We sought to examine temporal trends in relative abundance and describe current size structure, body condition, and population dynamics of these two remnant populations. Both populations had decreasing relative abundance over the previous 24-y period, although decreases in the Lovewell population were most profound. In Milford Reservoir, the median total length of sampled Goldeye was 268 mm (minimum = 235 mm; maximum = 431 mm). The estimated maximum observed age for Goldeye was 8; however, age-1 Goldeye were the most abundant year-class that we collected, accounting for 80% of sampled fish. We fit a von Bertalanffy growth model to back-calculated length at annulus formation with parameter estimates of L∞ = 402 mm, K = 0.93, and t0 = 0.29. We collected two individuals at Lovewell Reservoir; therefore, no analyses were conducted. Overall, this study provides cursory knowledge of two remnant Goldeye populations in Kansas. These results can be applied to promote better understanding of their ecological role in these reservoirs and other midwestern impoundments with remnant populations.

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.
