- Abstract
- Rearing water temperatures, a major factor in flounder farming in Jeju and Wando regions, the average water temperature in Jeju was 19.7℃, the highest and lowest water temperature were 28.4℃ in August and 14.0℃ in February, respectively. The average water temperature in Wando was 15.7℃, the highest was 25.8℃ in August, the lowest was 14.0℃ in February. The low water temperature problem in Wando is solved by controlling the breeding water temperature using the heat pump or by raising mid-breeding fish (about 20 cm body length). According to a survey of the breeding management of flounder in Jeju and Wando, the weight of fish in Wando has become heavier by 200 g to 300 g faster than in Jeju. The survival rate of fish was about 74% in Jeju, with Wando being about 90%. Results of flounder farming management factors analysis in Jeju and Wando regions with the breeding environment of fish farm, the production per unit area of flounder was 25 kg/㎡ in Jeju and 28 kg/㎡ in Wando. The cost of producing 1.0 kg of cultured flounder was 9,718 won for Jeju and 8,030 won for Wando. MP feed prices are higher in Jeju than in Wando due to differences in logistics costs. The unit price of cultured flounder is lower in Jeju than Wando due to problems in its merchantability and circulation system.
