Efisiensi Penggunaan Jenis Filter Dalam Sistem Resirkulasi Terhadap Kelulushidupan Dan Pertumbuhan Ikan Selais (Ompok Hypophthalmus)

---

One of the methods that can be done in intensive aquaculture on small
area is the use of a water recirculation system. Recirculation is a system that uses
filtered water continuously. The recirculation success depends on the system
effectiveness on treating waste, especially organic waste, one of which is the type
of filter that used in recirculation system.
This study was aimed to find the best filter in water reciculation system.
This study was conducted in May-August 2019. The fish with body length of 6,8-
7,8 cm and body weight of 1,07-2,36 g were reared in 60x40x40 cm aquarium and
water volume of 60 litre, fed with commercial pellet PF 800. The method used in
this study was experiment with Randomized Block Design, one factor which is
filter types and 5 treatments which are dacron, bioball, gravel, charcoal and
zeolit. Parameters measured were water quality, blood glucose, survival rate,
absolute body length/weight and spesific growth rate.
Results shown that the using of different filter types in water recirculation
system affect the growth and survival rate of O. hypopthalmus. The lowest NH3,
NO3, and NO2 concentration was found in bioball filter, which respectively were
0.05±0.01 mg/L, 0.65±0.19 mg/L, and 0.33±0.01 mg/L. The treatment with the
lowest glucose level is bioball filter, which is of 67.25±9.07 mg/dL. The highest
survival rate was also found in bioball filter which was of 98.33±3.34%. The
highest absolute weight growth was found in the bioball filter which was of
6.22±1.20 g. The highest absolute length growth was also found in bioball filter
which of 4.52±0.48 cm. The highest daily growth rate was also found in bioball
filter of 2.54±0.47%. Based on data obtained, it can be concluded that using of
bioball filter in water recirculation system in rearing O. hypopthalmus provide
the best results in growth, survival rate and reduce the stress level of fish.
