Raise Fish in the Garden Pond

Catfish (hito) fattened in our garden pond have become pets; the biggest measures 2 ft long.

Water from the pond is rich with algae, plant nutrients and detritus. While you water your plants, you are also fertilizing them. The pond should be designed for growing tilapia, hito or dalag, or a combination of these. For tilapia, keep its population low to avoid overcrowding and competition. Stock fingerlings of the same size and age.

Try growing hito, native or African. When you buy live hito from the market, separate the small ones (juveniles), which will serve as your growers. They are ready to harvest in 3 to 6 months with 3 pieces making a kilo. Hito is easier to raise than any other freshwater fish. One thing is that you do not change water often because the fish prefers to have a muddy bottom to stay.

Feed the fish with chicken and fish entrails, vegetable trimmings, dog food, etc. Just avoid accumulation of feed that may decompose and cause foul odor, an indication that Oxygen is being replaced with Carbon Dioxide and Hydrogen Sulfide.

Azolla, a floating fern, is good fish and animal feeds because it contains 20 to 25 percent protein,. It is also an excellent organic fertilizer because it is rich in nitrate, a product of nitrogen fixation by Anabaena, a microscopic blue-green algae living in the fronds of Azolla. Nitrate is important for plant growth. Grow Azolla in a separate pond, or in floating cage, so as to maintain a regular biomass supply. ~
