Breeding and Larval Rearing of Bluefin Leatherjacket, <i>Thamnaconus modestus</i> (Günther, 1877) Under Commercial Scales
Bibliographic record
Abstract
The spawning of wild caught broodstocks bluefin leatherjacket ( Thamnaconus modestus ) as well as the development of egg and larvae were studied under commercial scales. Spawning period was lasted 55 days from 15th June to 9th August, 2010. Total 4.3 million eggs were collected during the spawning period, and 65.5% of eggs were subjected to be properly hatched and developed. The diameter of the eggs was in range from 0.59mm to 0.63mm. Total 1.8 million newly hatched larva were obtained in present study with a hatching rate of 41.7%. First feeding was observed on 3 days post hatching (dph), and the yolk sac was completely exhausted on 4 dph. Metamorphosis occurred between 29 dph and 33 dph, at the total length (TL) of (11.93±2.18) mm. The growth in terms of TL can be expressed as a polynomial equation TL=3.30394-0.31862(dph)+0.02222(dph) 2 (r 2 =0.90362, n=427). After 70 days rearing, 0.3 million juveniles (TL>40 mm) were obtained and the ratio of seedling/newly hatched larvae was 5.62%. The results in this study demonstrated that bluefin leatherjacket was feasible breeding under artificial environment, and our results might provide some technical guidance for the further application in breeding this species.

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