HALLAZGO DE BUCEPHALUS MARGARITAE OZAKI ET ISHIBASHI, 1934 (TREMATODA: BUCEPHALIDAE) EN EJEMPLARES DE SPHYRAENA PICUDILLA POEY,1860 (SPHYRAENIDAE) CAPTURADOS EN LA BAHÍA DE MOCHIMA, ESTADO SUCRE, VENEZUELA
Bibliographic record
Abstract
RESUMEN: Se encontraron 56 trematodos digeneos en el estomago de diez “picuillas chinas”(Sphyraena picudilla Poey, 1860) capturadas en la Bahia de Mochima. Estos parasitos fueron fijados en Bouin, tenidos en acetocarmin de Semichon, aclarados en aceite de clavo y montados en balsamo de Canada. Los ejemplares se identificaron como pertenecientes a la especie Bucephalus margaritae Ozaki et Ishibashi, 1934, considerando las caracteristicas morfometricas y corporales, en donde resalta el rhynchus con siete tentaculos retractiles. Esta especie es cosmopolita, y utiliza preferentemente a peces de la familia Carangidae como hospederos definitivos. B. margaritae se registra por primera vez para la bahia de Mochima y el pez S. picudilla constituye un nuevo hospedero, por lo que con la presente investigacion se amplian las zonas de localizacion geografica y la lista de hospederos para este digeneo. Se presenta una tabla comparativa de la especie estudiada. Palabras clave: Bucephalus margaritae, Trematoda: Bucephalidae, bahia de Mochima. ABSTRACT: Fifty-six digenean flukes were found in the stomach of 10 «picuillas chinas» (Sphyraena picudilla Poey, 1860) caught in Bahia de Mochima, Venezuela. The parasites were fixed in Bouin solution, stained with acetocarmin of Semichon, clarified in clove oil, and mounted in Canada balsam. The specimens were identified as belonging to the species Bucephalus margaritae Ozaki et Ishibashi, 1934 on the basis of morphometric and body characteristics, the rhyncus standing out with seven retractile tentacles. This species is cosmopolitan and favors fish belonging to the Carangidae family as a definitive host. This study constitutes a first Mochima Bay registry for B. margaritae as well as a new record for S. Picudilla as a host of the former, signaling a larger geographic scope for this trematode and its hosts. Key words: Bucephalus margaritae, trematoda: Bucephalidae, Bahia de Mochima
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.
