Experimental Investigation of Fish Farm Hydrodynamics on 1:15 Scale Model Square Aquaculture Cages
Bibliographic record
Abstract
Hydrodynamic drag and wake properties of square aquaculture cage arrays were studied to improve understanding of nutrient dynamics from fish cages to guide the design of integrated multitrophic aquaculture (IMTA). A 1:15 scale model array (2 × 3) of square cages was developed and deployed in a large recirculating flume tank. Drag measurements were measured for individual cages within the array relative to current velocity. Results showed the highest drag for the first row of cages, with drag reducing significantly through rows 2 and 3. A wake velocity study observed velocity deficits, wake topology, wake recovery, and turbulence in the flow fields. High-velocity deficits were measured directly behind cages within the array, causing flow to be accelerated around and below the cages. The presence of a shear layer in the wake of the cages caused high levels of turbulence downstream. These results can be used to help predict patterns of nutrients released from cages into the environment and aid in the placement of nutrient extractive species in IMTA systems.

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.
