Morphological And Molecular Characterization Of Infectious Parasites In Argentine Hake Fish Traded Via Aqaba Port Of Jordan
Bibliographic record
Abstract
Various parasites were found in raw fish, and the majority of the scientific literature describes methods for controlling major parasites of concern in the Western World, such as Anisakis parasites (Beldsoe & Oria, 2001; Harvell, 1999). According to archive records, the Argentine Hake fish (Merluccius hubbsi) was the most parasitically infected fish species (81.8%). In addition, Argentine Hake fish was the most imported fish and had the highest infection rate, violating Jordanian standards when compared to other species of fish infected by parasites. Thirty-three Argentine Hake fish samples were collected from Jordan's Aqaba port. Total bacterial count and culture for Salmonella, Vibrio, Pseudomonas, and E. coli was done. Freshness, Heavy metals, pH, crude protein and lipid, Moisture, Salt, Collagen, Total Volatile Base Nitrogen (TVBN), and Histamine were among the tests performed on those samples. According to the PCR assay, the main parasites isolated from the Argentine Hake fish were Myxosporea kudoa (Kingdom: Animalia, Phylum: Cnidaria, Class: Myxosporem, Order:Multivalvulida, Family: Kudoidae, Genus: Kudoa). In addition, it was demonstrated that the severity of parasitic infection led to a significant increase in acidity, salt, fat, and water content in the muscle (P>.05). Furthermore, the severity of parasitic infection led to a significant decrease in protein, collagen, TVP-N, freshness, and bacterial count. Here, parasite density is quantified as the number of parasites per kilogram of fish (>1 parasite/kg fish wt.). The results of this study suggest that local markets urgently require additional control measures, including the assistance of skilled inspectors. Additionally, it was advised that enough samples be taken from each shipment of fish to allow for a reliable analysis at the specialized labs. Additionally, change the Jordanian standard to "prevent entry of contaminated frozen fish with parasites in the flesh whether it is pathogenic or non-pathogenic," particularly in those parts that deal with frozen fish.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
