Effect of Density and Oxygen Packaging on Survival Rate of Thai Fairy Shrimp (Branchinella thailandensis) for Transport

Abstract

Effect of density and oxygen packaging on survival rate of Thai fairy shrimp (Branchinella thailandensis) for transport. the experiment design was 5x3 Factorial in Randomized Complete Block Design, 5 replicates. The first factor density of Thai fairy shrimp 20, 40, 60, 80 and 10 ind/ 100 ml and the second factor was packaging as no oxygen, oxygen powder (Sodium Percarbonate; 2Na₂CO₃. 3H₂O₂) and oxygen gas. The results showed that longer transportation times and higher transportation density contributed to a significant decrease in the survival rate of Thai fairy shrimp (P < 0.05). Effect of oxygen powder and oxygen gas on survival rate was significantly (P < 0.05) higher with no oxygen content at every hours. It is concluded that transported Thai fairy shrimp were transported well within 6 hours. Thai fairy shrimp contained the highest 100 ind/100 ml of oxygen gas, survival rate was 100.00 ± 0.00% and Thai Fairy shrimp transported no oxygen or powdered oxygen only 60 ind/100 ml had survival rates of 92.26 ± 1.10 and 98.58 ± 2.03 %, respectively.
