Masalah Pada Budidaya Ikan Kerapu
1. Kematian akibat penyakit, disebabkan oleh : - Jamur : Ichthyophonus sp - Bakteri : Vibriosis (including: V. parahaemolyticus) infection, Pseudomonas infection, Streptococcal infection
Flexibacter infection and Bacterial Gill Diseases - Virus : Viral Nervous Necrosis (VNN), Iridovirus - Parasit : Protozoans, Monogeneans, Nematodes, Copepods and leeches
2. Degradasi kualitas lingkunganToksisitas logam berat, air limbah, pakan yang tidak dikonsumsi, ….dsb

Survival Percentage (%)
Fig 1: Histogram of the mean survival (%) of tiger grouper challenged with V. parahaemolyticus at 105 cells/ml. Survival was scored at 72 hours after AquaHerb immersion and the addition of V. parahaemolyticus for the challenge.
Each experiment was repeated twice and similar results were observed. Significant differences among the treatments and control at corresponding time of herbal exposure are indicated by different letter ( p< 0.05).
