摘要: Optimum conditions for the transportation of juvenile silver pomfret, Pampus argenteus (Euphrasen 1788) were investigated under simulated conditions. Juveniles (5.22 +/- 1.09 g) were kept in 10-l plastic bags containing oxygen and 3 l water at 15, 20, and 25 C in (a) low loading densities (5, 10, 20 g/l) for 8 h and (b) high loading densities (20, 30, 40 g/l) for 4 h. Following simulations, water was sampled to measure dissolved oxygen, pH, and total ammonia. Both survival rates and dissolved oxygen levels decreased when the temperature and loading density increased; pH decreased significantly under all transportation conditions. High loading density (30-40 g/l) and temperature (25 degrees C) resulted in high total ammonia and mortality (54-64%). The ideal temperature for transporting juvenile silver pomfret in plastic bags was 15 C. At this temperature, the highest survival rate was recorded, even at loading densities of 40 g/l. Transport at high temperature (25 degrees C) and loading density (20 g/l) should not exceed 8 h, due to raised mortality (>30%) and ammonia levels.
