Gonadal Maturation and Histological Observations of Epinephelus areolatus and Lethrinus nebulosus in Halaieb/Shalatien Area "Red Sea", Egypt
Bibliographic record
Abstract
Epinephelus areolatus and Lethrinus nebulosus are the highly abundant species in the two dominant families (Serranidae and Lethrinidae) in Halaieb/Shalatien area. The objective of the present study is to describe the phases of gonadal development and determine the spawning season of the two mentioned species. Results showed that E. areolatus attains first sexual maturity at 22.8 cm (Total Length) for males and 23.5 cm for females while L. nebulosus attains it at 25.1 cm for males and 26.2 cm for females both after their second year of life. The gonadosomatic index indicated that, the spawning season of E. areolatus was in May and June and it was in June and July for L. nebulosus. The different stages of oogenetic development were examined microscopically. It was concluded that, six stages for oocyte developments of the two species under study were identified. Fish samples were collected monthly from the city of Shalatien landing center which is considered as the main Gonads were prepared for the histological landing center in the area of study. Gutted weights to the examination by fixing the gonads in buffered nearest gram and gonads weights to the nearest milligram formaldehyde. They were dehydrated in graded alcohol of both sexes of the two species under study were series, exposed to Xylol and embedded in paraffin wax. recorded for a total of 432 fish. The gonadosomatic index Sections from 4 to 7 µm thick were prepared from the was calculated for all the specimens as a percentage of middle parts of the gonads. The sections were stained gonad weight to the gutted fish weight as shown in with Hematoxilin and Eosin (2), then mounted in Canada following equation: balsam and photographed with an Olympus CX41 digital

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; a candidate call from one teacher head, not a consensus.
