Shrimp growth patterns will dynamically affect feeding and organic waste conversion in the pond ecosystems. The purpose of this study was to determine dynamic correlation between amount shrimp biomass, feed, solubility matter ecosystem at Salafiyah Syafi'iyah Islamic Boarding School Sukorejo, Situbondo Regency. research method used is an ex-pose facto causal design with time series field data c...

Mangrove biochar residue was used for nitrogen adsorption and retention in sediment, which is beneficial plant germination. The present study investigated the effect of contact time (5–360 min), dosage (0.2–2 g L?1), pH (5–6), initial concentration (2–10 mg L?1) on NH4+-N NO3?-N adsorption. Three different isotherm models were to fit experimental data. Column leaching experiments conducted inve...

Vibrio species is one of the pathogenic bacteria infecting shrimps in aquaculture farm has caused severe loss to farm. The aim this research isolate and compare presence spp. commercialize shrimp during stocking process final harvest phase productions. Quantification isolation were conducted measured using Log CFU (colony forming units) counts morphological investigation gram staining conventio...

Antibiotics are compounds that used to inhibit the growth of disease or commonly referred as drugs. Some examples antibiotics most in shrimp culture tetracycline, oxytetracycline, and chloramphenicol. In farming, function prevention a cure for disease. But if application is not under dose, it will cause residues on harm human health consumed. The purpose this study was determine antibiotic cont...

Biological settling ponds are a practicable approach for treating super-intensive shrimp aquaculture wastewater almost all producers in the Vietnamese Mekong Delta (VMD). The optimization of hydraulic retention time (HRT) biological plays crucial role establishing stability outflow quality and suitability pond area (SPA). This study aims to suggest appropriate HRT SPA treatment systems based on...
