The Crab Farming with Automatic Crab Farm Control System

Abstract

          The purpose of this research was to study the growth rate. and the survival rate of The Crab Farming with Automatic Crab Farm Control System. It's an experimental research. The samples were Sayamia germaini and Sayamia bangkokensis 3-4 months old. The experiment was divided into 2 groups with 3 replications each. The first group was S. germaini, the second group was S. bangkokensis, using a completely randomized design (CRD) experimental plan to collect growth data. The survival rate was dropped every 1 month until 4 months, then the results were recorded and the data were analyzed by percentage, mean and standard deviation.
          The results showed that the mean weight gain of male S. bangkokensis was 0.8 g higher than that of male S. germaini, and that of male crabs of both species had weight gain higher than that of females. As for the increased carapace length, it was found that female S. germaini was 0.3 cm taller than S. bangkokensis. crab survival rate The average survival rate was as high as 94.17 percent and found that females had a higher survival rate than males. Water temperature in the crab pond It was lowest at 8:00 a.m. at 27.6 ± 0.14 °C and highest at 12:00 noon at 30.1 ± 0.62 °C. The pH of the pond water was 6.8 ± 0.09 - 7.1 ± 0.11.
