Strip Spawning Methodology for Captive Propagation of Broadcast-Spawning Cyprinids in the Great Plains
Bibliographic record
Abstract
Abstract In the summer of 2011, large parts of Texas and Oklahoma experienced their worst drought in recorded history. Most of the rivers and streams in this region are inhabited by cyprinids that broadcast semibuoyant pelagic ova. These fish depend on flowing water for the hormonal cues that induce spawning and to allow ova to develop and hatch as they float downstream. During the drought, the Brazos and Canadian rivers, Texas, were reduced to isolated streambed pools. Monitoring efforts concluded that pelagic, broadcast-spawning cyprinids experienced complete reproductive failure in the Brazos River and had very little spawning success in the Canadian River. Personnel from the Texas Parks and Wildlife Department, U.S. Fish and Wildlife Service, and Texas Tech University began salvage operations in both rivers in September 2011 to ensure the survival of imperiled cyprinids. In spring 2012, standard captive propagation techniques were used with several species of cyprinids, with little success. As a result, we developed new techniques for four species of pelagic, broadcast-spawning cyprinids from the Brazos and Canadian rivers that could greatly increase hatchery program efficacy.

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.
