Recently me and my friend got hold of 19 fresh and salt water ponds all together. We had tried farming Sea Bass, Red Tilapias and Threadfins the last 9 months but due to the long duration from 5cm frys till 700gms as per market requirements, the risk factors is too long as all the ponds are open-air without roofing.
As each pond is 120m x 30m and some are 120m x 60m are too big to cover-up, we tend to loss many fishes during raining seasons as here in Malaysia have unpredicted rain fall through the year.
Now we have switch to buying fish eggs and frys and farm it until 5cm to sell. The duration is betweem 1.5 to 2 months. At present we are buying Red Snapper and Sea Bass eggs for breeding.
But due to the sudden change and the little knownledge that we have, our last 3 attemps failed resulting in about only 15,000 fishes survived out of 100 million eggs that we purchased.
I wouls like to seek advise from all friends here if you have and knowledge on this breeding so that I can understand more in order to increase my output of fishes.
