Studies of the biology of swim bladder nematodes, Cystidicola spp. (Habronematoidea) / John Douglas Smith. --
Bibliographic record
Abstract
The life cycle and larval development of swim bladder nematodes, Cystidicola spp., have been elucidated. C, farionis developed in three species of amphipod. Naturally infected amphipods have been found previously but one well known report was not valid. C. cristivomeri. developed in Mysis relicta but not in amphipods. Naturally infected mysids were found. The third-stage larva of Cystidicola spp. and other cystidicolids undergoes considerable growth and development, but not the third moult, in \nthe intermediate host. \nC, cristivomeri was found in lake trout, brook trout, a new host record, and lake whitefish, probably an abnormal host. The intensity of infection of c. cristivomeri in lake trout in northwestern Ontario lakes was very high where the trout may be planktonivorous throughout their life. C, cristivomeri may have disappeared from the Great Lakes when lake trout populations \ndeclined severely. C. farionis was found in a variety of salmonids including introduced species in Lakes Huron and Superior. Eggs of C. farionis had mostly lateral filaments in lake whitefish and mostly polar filaments in other fish hosts. The number of filaments was variable. Changes in the intensity of infection in lake whitefish with age likely relate to changes in amount and kind of food eaten and growth rate of the fish. The movements and feeding \nhabits of the fish hosts determine which amphipods are important \nin natural transmission of the parasite.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
