Greetings!

I intend to ‘commercially’ grow tilapia in a recirculating aquaculture system coupled with hydroponic method of growing veggies & crops. Anyone in here (Philippines) who’s been very succesful in AQUAPONICS? I am currently making a blue print for such a project and I thought someone out there might want to engage in brainstorming about such projects. Say, consultancy gratis et amore.

Unsolicited advise are most welcome.

Thanks,

Ramon

@Sha, there’s an instructional manual/book you can buy at TRC: 727-6205 or Marid Digest: 373-4446 about self-mix feeds for poultry and aquaculture. the price is around P300.

Hi Leo.. thanks for your very good articles refer sa comment mo about self-mix feeds do you have any idea paano gawin un? Actually the tilapia is already 201days with all the correct feeding still maliit pa rin for commercial sale dyahe naman super mahal if continue ako ng grower and finisher. Thanks hope u can give me additional info about self mix feeds. thanks ulit

I have learnt more information about telapia culture in floating cage on river and I also started the project in Bangladesh. But now I want to know the technology about poultry rearer on floating cage. So please send me the address, pictures if possible.

Thanks

Thanks for the info, J. P. Baldia. I think the obvious solution is to put an aerator or to decrease the number of fish in the pond to 1500. I wil opt to decrease the number of fish and release the others to the river nearby. But if I can secure an aerator, can it help or frequent changing of water will do? If you will not mind, I want to ask more specific questions about this topic since I am planning to make this a business when I retire from working abroad. My e- mail add: rayjo@emirates.net.ae
Thank you again.

Yes, Mr. Garcia. You overstocked. Your 300sq.m. pond can only hold a maximum of 1,500 fish until harvest. This is assuming that you have a 1 meter water depth and without aeration.

Presuming that you have good quality feeds and fingerlings, the main reason why tilapia will not grow is low level of dissolved oxygen in the water. Keep in mind that oxygen is a function of metabolism and no matter how much feed you give your fish, they still will not grow.

With overstocking, your fish will compete for the limited amount of oxygen in the water. Therefore it follows that when you provide aeration, you can stock more.

Of course, the level of oxygen will also decrease if your water is “dirty”, meaning, it has high organic load. The solution for this is simply to change water.

You will know that oxygen level is low in your system when your fish are always at the surface of the water, gasping for air.
Good luck

i contructed a 300 sq meter pond and watered by deepwell also. i stocked the pond last june with 6ooo all male tilapia fingerlings. as of this september 2009, most of the fish reached about 2 to 3 inches in length.i’m feeding them with commercially available fish food. i’m wondering if the fish has stunted growth. did i overstocked? please help. it’s supposed to be my pilot project and want to add two more ponds if this first one will become succesful. thank you very much

Go to the demo farm of BFAR in La Trinidad. Their farm is inside the compound of Benguet State University. Their regional office is inside the Bureau of Plant Industry compund along Bokawkan rd.

Hi Allen:
You can use dried hog manure to fertilize the pond in order to enhance the growth of natural food (phytoplankton and zooplankton) which are food to your tilapia. However, the amount is regulated to around 1,500kg manure per hectare. Excessive organic loading in your pond will cause low oxygen level in your water resulting to stunted growth of the fish. Oxygen is a function of metabolism. Low O2 means low metabolism of the fish.

Hi Dennis:
You can certainly use deepwell water but it will be expensive to pump. Shallow well and surface water is more preferred.
