SEASONAL VARIATION IN MACRO-MICRONUTRIENT COMPOSITIONS OF THE FLESH AND SHELL OF THE PORTUNID CRAB Callinectes amnicola (De Rochebrune, 1883) FROM THE COASTAL WATERS OF SOUTHWEST NIGERIA
Bibliographic record
Abstract
Portunids are decapod crustaceans of high economic importance. Seasonal variation in macronutrient and micronutrients contents of Callinectes amnicola from three interconnecting lagoons were investigated using standard methods. The percentages of protein and moisture contents in the flesh were higher than that of the shell, while higher ash and nitrogen free extract were obtained in the shell. Crude fibres was not detected in flesh of C. amnicola but detected in shells with values ranging from 0.30 ±0.72 % (C. amnicola from Lagos Lagoon) to 0.55 ±2.15 % (C. amnicola from Badagry Lagoon). There were statistical differences (P ˂ 0.05) in crude fibre and carbohydrate levels of the crab shell during wet and dry seasons while significant difference exist in protein level only in wet season. Protein showed negative correlations with all the minerals in crabs from Badagry and Epe Lagoons but positive correlation with all examined minerals in Lagos Lagoon crabs. The study demonstrated that Callinectes amnicola is rich in macro-micronutrients and characterized by low lipid content (< 3%). The nutrient biochemical constituents in the crab species vary with season

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.
