A variety of antibiotics and other chemicals are used in aquaculture for various purposes, including to promote growth and reduce mortality, as well as to treat and prevent disease. As part of the larval rearing of crustaceans such as prawns and shrimp, antibiotics such as Treflan and Furazolidone are used to increase the survival rate of the post-larvae. In this study, the combined effect of Treflan and Furazolidone on the molting frequency, growth performances, and survival of blue swimming crab (BSC, Portunus pelagicus) instar reared in fiberglass tanks was determined. Two treatments with three replicates each were tested. Twenty (n=20) individual crab instars of uniform size (average length 1.5 ± 0.00 cm and average weight 10.33 ± 0.00 g) were stocked per circular fiberglass tanks, each with a water capacity of 200 L for 37 days culture period starting from the crab instar up to the juvenile stage. Treatment 1 corresponds to the control without the application of Treflan and Furazolidone (NTF). Treatment 2 represents the use of Treflan and Furazolidone (TF) at the dosage of 0.2 ppm and 0.3 ppm, respectively. The results showed that the growth and molting frequency of BSC instar were not affected by TF application at the end of the culture period. In both treatments, survival rates declined due to the frequent and excessive use of TF, which might be the reason for descending rates. Hence, the combined effects of TF did not enhance the molting, growth, and survival performance of BSC instars when administered as therapeutics.
