Growth Performance of Synodontis eupterus in Preservation Media with Salinity

Abstract

Good environmental condition supported by sufficient feeding and provision of good container with optimum salinity can increase the production output. This research aimed to obtain information about the relationship of salinity with growth of sinodontis. The fry that used have average length of 3,41+0,04 cm with average weight of 0,60+0,02 g which comes from Cibinong, West Java. The fry first adapted into aquarium and next treated on 0, 2, 4 and 6 treatment with 3 repetitions. Containers used for the treatment are 12 aquariums which have dimension of 30x25x25 cm3. Each one is filled with 15 liters of water. The length of time for the development of the fish is 28 days. During the period of time, the fish were fed with silkworm twice a day in the morning and in the afternoon in at satiation. Water replacement is 75% volume per day. Salinity treatment significantly affects (P<0,05) length growth rate (LPP), weight growth rate (SGR), and feed efficiency (EP). Treatment with 2 ppt salinity showed the best production performance.
