Indoor Aquaculture Potential of Duckweed (<i>Lemna minor</i>) and the Need for Adoption in Kenya
Bibliographic record
Abstract
Duckweed ( Lemna minor ) culture has been explored as a possible macrophyte based ingredient for partial or full substitution of both soy bean or fish meal in fish feeds in China and India but has seldom been explored in Kenya to establish its growth conditions. To demonstrate the culture potential of L. minor in aquaculture, culture technique was homogenized in indoor plastic tanks using chicken manure at an optimum water depth of 30 cm. Temperature ranged from (25.84±0.19) to (28.24±0.08) °C. After 10 days L. minor attained 100% cover and was harvested three times in a month. The overall yield was (1.09±0.09) kg/m 3 /month. The Relative Growth Rates was higher during the first harvest (0.38 g/day) and decreased in subsequently (0.12 and 0.10 g/day) for the second and third harvests respectively. Dissolved oxygen decreased with L. minor growth and ranged between (0.84±0.19) and (2.52±0.52) mg/L. pH. values ranged between (5.89±0.32) and (7.23±0.23) throughout the study period. The present study demonstrates that L. minor can be cultured using cheap and locally available organic manure in aquaculture sector. Therefore, there is need to embrace L. minor culture technologies by small scale farmers for sustainable aquaculture production in Kenya.

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.
