Abstract
This study compared the efficiency of microinjection, electroporation, and transfection methods for gene transfer into shrimp zygotes. Transfection using the jetPEI reagent demonstrated the highest efficiency, with hatching rates of 50%-60% and gene expression rates of 40%-60%. Additionally, a VP28-pseudotyped baculovirus system achieved up to 100% infection efficiency in adult shrimp tissues, although it exhibited tissue-specific tropism. A triple-pseudotyped retroviral system also showed promise, particularly in shrimp primary lymphoid cells, with infection efficiencies of 20%-30%. Furthermore, the inclusion of shrimp-specific promoters and viral envelope proteins significantly enhanced the tropism and infectivity of lentiviral vectors in shrimp cells. The findings indicate that transfection with jetPEI and the use of pseudotyped viral systems are highly effective for gene transfer in shrimp. These methods hold significant potential for advancing genetic manipulation and cellular studies in shrimp, which could lead to improved disease resistance and other desirable traits in aquaculture.

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 it
