Bibliographic record
Abstract
A sian A quacultureThe Philippines is the fourth biggest catfish-producing country in Southeast Asia in 1997 to 2001.Next to tilapia, catfish is the second highest freshwater fish produced in fishponds in 2001.In Asia and the Pacific, highest production comes from Clarias spp. of the family Clariidae.Of great importance in fisheries and aquaculture and the most well-studied species among the clariids are the Asian catfish Clarias macrocephalus and C. batrachus, and the African catfish C. gariepinus (C.lazera).Because of its tender and delicious meat, the native catfish or 'hito' or C. macrocephalus (picture this page) is one of the favorite freshwater food fishes in the Philippines.Before the early seventies, it is abundantly found in the rice fields and other natural habitats in the Philippines.At present however, C. macrocephalus is scarcely found in rice fields or any of its natural environment.Some observers hypothesized that the fast disappearance of C. macrocephalus is due to its interbreeding with C. batrachus, a closely related, faster-growing species introduced from Thailand in the 1970's.In Thailand, there is almost the same number of C. macrocephalus and C. batrachus, while in Vietnam, there is a more abundant supply of C. macrocephalus than C. batrachus.C. macrocephalus and C. batrachus are almost similar in size and appearance.C. macrocephalus can be distinguished from the Thai catfish C. batrachus by the shape of the occipital process, blunt or rounded in the former

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
