Intercontinental transfer of adult Acipenser oxyrinchus– impact assessment of aviation transport conditions on blood parameters
Bibliographic record
Abstract
In order to facilitate intercontinental air transport of live \nsturgeon broodstock, a simulation test for an 8-h flight was \nperformed in a pressure chamber (pressure profiles resembling \nconditions during trans-Atlantic cargo flights). Atlantic sturgeon \n(Acipenser oxyrinchus) were maintained in sealed polyethylene \nbags with water and an oxygen-enriched atmosphere \nat a ratio of 1 : 5 : 10 (fish:water:oxygen by volume) over a \n10 h period at 15 Celsius water temperature. Minimum pressure \nduring the simulated flight was regulated at an elevation of \n2600 m equalling 850 hPa. Decompression and compression \nphases to simulate takeoff and landing were set at 30 min each. \nRespiration frequency was recorded during flight simulation. \nBlood pH, blood pO2 and pCO2 as well as Ca2+, Na+, K+, \nCl), glucose and cortisol, cholesterol and trigycerids were also \nmonitored prior to and after transport (at 12, 24, 36, 280 and \n366 h). During exposure in the bags, blood pH decreased from \na mean of 7.35 to 7.11 and blood pCO2 increased from 2.48 to \n8.53 hPa. Both parameters revealed the most significant \ndeviations from control levels immediately following the trial, \nreturning to normal levels after 36 h. In contrast, the Na2+, \nCa2+and Cl) ion as well as glucose concentration required \n72 h following the simulated transport until baseline levels \nwere reached. During the subsequent transatlantic transport \ntrials from Canada to Germany, blood parameters were \nutilized to assess fish recovery following transport. Additionally, \ntesting of the transport water revealed that NH4–N \nreached critical levels of 6 mg l)1 within 16–18 h when the fish \nwere kept in the sealed bags at 10 Celsius. Following transport, \nadaptation of pH in the water of the rearing facility to levels of \npH 6.9–7.0 for 20–28 h minimized toxic NH3 concentrations \nand ensured recovery. Recovery times varied to a large extent, \ninfluenced by the condition factor of the fish. Fish survival was \n100% for 2 months post-transport, indicating that the critical \nparameters were met during transport.

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.
