Aplikasi Pertama Budidaya Ikan Nila Dengan Sistem Bioflok

Summary

The video demonstrates the creator’s first preparation of water for a tarpaulin pond using a biofloc system for freshwater fish farming, including tilapia.

Materials and application

The creator dissolves each ingredient in water and distributes it evenly around the pond’s aeration points:

• Coarse salt (NaCl): Use 1 kg per cubic meter of water. For the creator’s 1.5 m³ pond, he uses 1.5 kg. He recommends coarse salt over table salt, which may contain additives such as iodine.
• Dolomite lime: Use 50 g per cubic meter; the creator weighs 75 g for 1.5 m³. Dolomite is described as helping stabilize pH and speed up biofloc formation. More may be needed if the dolomite contains a lot of coarse material.
• Molasses (carbon source): The stated rate is 100 ml per cubic meter, but the creator says he adds 50 ml for 1.5 m³. This is a dosage inconsistency in the subtitles. Molasses supplies carbon for heterotrophic bacteria, which contribute to biofloc formation. If molasses is unavailable, the stated substitute is granulated sugar at 50 g per cubic meter; the creator uses 75 g for 1.5 m³.
• Probiotics: Use 10 g per cubic meter, or 15 g for 1.5 m³. Dissolve the probiotics before spreading them. They add beneficial bacteria that break down uneaten feed and fish waste, helping form floc that fish can consume as supplemental feed.

After application

• Keep the pond’s aeration running continuously for about seven days.
• Cloudy, brownish water and somewhat slippery pond walls are identified as signs that biofloc has formed and the water is ready.

The video closes by noting that a future installment will cover how to stock fish seed while keeping the fish healthy and minimizing losses.
