If you have any business idea someone can start with 600,000 in Asaba please share. I am open and interested with any idea you have and also you never know you can change someone's life who is willing to start a Business.

Catfish farming.
Hire a pond that has water flowing in from the ground. Preferrably close to the river in asaba and stock 5000 post fingerlings.
Break down.
Hire the pond for 50 - 80k for a year.
Buy your post fingerlings at 17 naira for 1 and get extra 250 after buying 5000.
Spend about 500k in buying various sizes of fish feed that would be used to feed the fishes within the next two months and two weeks, then sell off the small sizes.
Money you get from the sale would be used to feed the remaining sorted fishes for another 2months and two weeks. Then sell off.
Note: you would be the one feeding your fish daily.
You might need to hire a scale, and a pumping machine and pay labour for those who would sort and drag the fishes for you when your buyers come

Are you into the Business?

Yes, ask around in asaba where catfish ponds are close to the river. Study those in the biz there, if you are convinced enough then you can start yours. My previous post has some omissions in it
