The use of superior common carp for a better aquaculture

Fish farming is an economic business activity that has been carried out for a long time in Indonesia. One of the most popular commodities cultured is common carp. In 2001, common carp production was 418,910 MT, equivalent to 63.5% of Indonesia’s national production. However, the existence of obstacles in common carp culture, especially the outbreak of KHV in 2002 and the decrease of the genetic quality of fish, indicated by the slower growth of fish, resulted in a significant decrease in common carp production. The use of lower genetic quality fish causes the efficiency of the feed used is getting lower, as indicated by the high value of the FCR. In-efficient use of feed has an impact on increasing feed waste in the cultural environment. To increase common carp production, several varieties of superior common carp have been released for the farmer. Empirically, superior fish carp have a better growth rate and are more efficient in the use of feed. Culture of these superior varieties impacted to increase in the national production of common carp, by an average of 8.7%/year. On the other hand, the culture environment is kept clean due to up to 47.0±4.8% reduction in waste.
