Pengaruh Suhu dan Salinitas Terhadap Respon Fisiologi Larva Tiram Mutiara Pinctada maxima (Jameson)
Bibliographic record
Abstract
ABSTRACT PENDAHULUAN Pinctada maxima adalah spesies akuakultur yang mempunyai nilai ekonomi tinggi (Taylor et al. 1997). Di pasaran internasional, mutiara yang diproduksi sering kali disebut dengan nama “South Sea Pearl”. Indonesia termasuk salah satu negara penghasil mutiara (South Sea Pearl) yang cukup diskenal di pasaran dunia, sebagian besar produksi South Sea Pearl yang dipasarkan berasal dari hasil budidaya (Anna 2006). Produksi mutiara berbasis budidaya merupakan aktivitas usaha yang menguntungkan. Perkembangan usaha budidaya mutiara saat ini sudah mengarah pada kegiatan industri yang terintegrasi (Fassler 1995). The Effect of Temperature and Salinity to The Physiological Respons on The Larvae of Pinctada maxima (Jameson). Energy budget is one of the most sensitive tools available for individual assessing environmental changes like temperature and salinity, and also prerequisite for individual growth and survival. The aim of this study is to obtained information on energy budget on routine metabolism, in different levels of temperature and salinity, and to know the levels of optimum temperature and salinity. The research was used randomized block design, with three replications. The result showed that optimal temperature and salinity on P. maxima larvae was 28 oC and 32 – 34 ‰ (BE and BF). Energy budget to routine metabolism increased was attributed to increased temperature and salinity due to the optimal, than would be decreased when temperature and salinity increased. The highest of energy budged for routine metabolism at treatment BF. Stage I: energy budged between 6.73 – 7.35 C g wet weight-1 hour-1 (28.18 – 30.74 J g wet weight-1 hour-1); Stages II: 5.85 – 5.95 C g wet weight-1 hour-1 (24.48 – 24.90 J g wet weight-1 hour-1); Stages III: 4.73 – 4.80 C g wet weight-1 hour-1 (15.07– 19.58 J g wet weight-1 hour-1). The highest survival rate of larvae was by treatment BF, but has not higher significant (P e” 0.05) with BE, stage I: survival rate between 87.75 – 87.92 %; Stage II: 81.91 – 82.39 % and stage III: 76.72 – 77.26 %. The best of relative growth length of larvae by treatment BF and not significant (P e” 0.05) with BE, at stage I: 29.78 x 17.93 ?m – 30.57 x 18.43 ?m (AP x DV); stage II: 57.62 x 46.73 ?m – 58.13 x 47.33 ?m and stage III: 80.32 x 69.29 ?m – 80.88 x 69.62 ?m. The quickest time of plantigrade stages have found by treatment BF (day 19.50) and hasn’t significant (P > 0.05) with BE (day 20.85).

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.
