Abstract

Catfish (Clarias sp.) cultivated with a combination of the addition of probiotics in the biofloc technology are thought to increase production. The frequency of adding probiotics from swamps to cultured water media has never been studied in ensuring the availability of flocks in rearing media. The purpose of this study was to determine the appropriate frequency of probiotics from swamps in the biofloc technology to improve the parameters of successful cultivation, especially increasing catfish production and biofloc formation. This study used a completely randomized design (CRD) consisting of two treatments and three replications. The treatment given was difference in the frequency of giving probiotics from swamps namely (P1) 1 time for 42 days of rearing (P2) 2 times for 42 days of rearing. The results showed that P2 was the best treatment with a floc volume of 68.33 mL L-1, absolute length growth 8.18 cm, absolute weight growth 19.30 g, feed efficiency 135.24 %, survival 89.33%, biomass production 24.639.50 g, temperature 28.85-29.59ºC, pH 7.27-7.42, dissolved oxygen (DO) 3.91-5.72 mg L-1, ammonia 0.45-1.15 mg L-1 and total dissolved solid (TDS) 717.33-885.50 mg L-1. Therefore it is recommended that probiotics from swamps be given to fish culture media with a frequency of 2 times during 42 days of rearing or once every 21 days.
