I was talking about indoor intensive RAS aquaculture. I got a quote from an european company for that system with 120MT/yr tilapia capacity.
I made calculations for an indoor completely flow through system with future possibility of turning it into complete RAS for the same breed and capacity.
Main problem is that you need to test it out on small scale initially, would cost app. 1-2million and about 8-12months for complete/reliable data. Then there's no reliable hatchery in market that can provide you with good quality seeds at reasonable price. You'll have to import which costs around rs.15-25/piece which is quite expensive and obvious exposure to exchange rate fluctuations. Cost of setting up a hatchery is not much but it takes time as well. So it's a good 1.5yrs or so with about rs.2-2.5 million of investment to test out a fully vertically integrated setup.
Rate of return is still decent but when it's Pakistan, you need a higher rate to compensate for risks associated with Pakistan being Pakistan.
