Abstract

fetched live from OpenAlex

Þorskeldi er vaxandi atvinnugrein í heiminum. Árið 2009 var framleiðsla á eldisþorski um það bil 18000 tonn í Noregi, 1000 tonn í Bandaríkjunum og Canada og um það bil 2000 tonn á Íslandi. Meðal helstu vandamála sem atvinnugreinin glímir við er það hversu hátt hlutfall lirfa deyr á fyrstu stigum eldisins eða fram að þeim tíma þegar hægt er að bólusetja lirfurnar. Á fyrsta tímabilinu eftir klak er áunnin ónæmisvörn ekki til staðar og þurfa lirfurnar því eingöngu að treysta á ósérhæfða ónæmiskerfið í baráttu sinni gegn utanaðkomandi sýklum. Með því að finna leiðir til að efla svörun ónæmiskerfisins á þessum fyrstu lirfustigum er talinn möguleiki á að auka megi lífslíkur þeirra. \nMarkmið þessa verkefnis var að mæla tjáningu á tveimur genum sem tengjast ósérhæfðri ónæmissvörun lirfanna, þ.e. IgM og lysozyme. Sýni voru tekin á tveimur mismunandi tímapunktum þ.e 10 dögum og 26 dögum eftir klak, af lirfum sem fóðraðar höfðu verið með lifandi fæðudýrum sem höfðu verið næringarbætt með ufsapeptíðum í tveimur mismunandi meðhöndlunarskömmtum. Til samanburðar voru lirfur sem fengið höfðu hefðbundin fæðudýr. \nNotast var við RT-qPCR aðferðina við magngreiningu á tjáningu IgM og lysozyme. Ubiquitin var notað sem samanburðargen við mat á tjáningu genanna. \nNiðurstöður rannsóknarinnar benda til þess að fóðrun lirfanna með peptíðbættum fæðudýrum auki tjáningu á bæði IgM og lysozyme. \nLykilorð: þorsklirfur, ósérhæfð ónæmissvörun, IgM, lysozyme, RT-qPCR

Not 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.
