The Performance of Rotifer <i>Brachionus plicatilis</i> (Müller 1786) and Chicken Egg Yolk on the Larval Rearing of African Catfish, <i>Clarias gariepinus</i> (Burchell 1822) in Hatchery
Bibliographic record
Abstract
800x600 The possibility of utilizing rotifer Brachionus plicatilis (Muller, 1786), broiler chicken egg yolk, and a mixture of the two as starter feeds in the larval rearing of African catfish ( Clarias gariepinus, Burchell, 1822) was explored. Larvae of four days following commencement of exogenous feeding were used for the purpose. The experiment lasted for 15 days under ambient hatchery conditions in a set of nine tanks of 900 litres capacity randomly allocated. The experiment was carried out in two phases. In the end of each phase, the larvae from each set of tanks were counted and from each feed treatment 30 larvae were randomly chosen and measured their weights and lengths for the estimation of average weight and length. The average lengths of the larvae from each phase and each feed treatment were used for the estimation of growth rates, survival %, specific growth rate (SGR), and conditional factor (CF). During the 1 st phase, the larvae fed with rotifers indicated the highest survival (98%) with poorest growth rate (25.76%/day). During the 2 nd phase (weaning period), the larvae fed with rotifers indicated the poorest survival (54%) while those fed with egg yolk indicated the highest growth (weight and length of 19.85±3.66mg and 12.13±0.60mm, respectively) and survival of 61%. The findings imply that rotifers are too small for the rearing of African catfish larvae, thus unsuitable. Chicken egg yolk can successfully be used as a substitute of live diet for rearing of African catfish larvae if need arises .

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.
