Sethu Vijayakumar

1. Before the tilapia body reaches 150 grams, the protein content should be 32%~35% of the feed, daily feeding amount is 3%~5% of tilapia total weight. Rich water cultivation also can be used, counting on animal waste to cultivate biological feed fish, generally spread manure once every week , 100kg-150kg each Mu(about 666m3).
2. After two to 3 months, tilapia body reaches the specifications of 250g/tail, entering the stage of mid term cultivation, then farmers should change the feeding mode, use all price tilapia feed stead of animal manure. At this point , the idea of feeding principle is to stick to the Fixed point, timing, quality and quantity of feeding, generally feed twice daily at 9 a.m. and 5 p.m. respectively. The fish feed amount is 3% to 4% of fish weight, and ensure protein content is 27%~29% within the feed.
3. When the individual reaches about 300 grams, the tilapia enter the fastest growing period, the daily feeding amount should be maintained at 1%~2% of fish weight, and therefore the content of protein in feed is above 35%. Fish should be fed feed five times daily. In fact, within the principle of not wasting feed, farmers feed the maximum amount as tilapia need, this will make tilapia grow faster. It are often developed to quite 1 kg / tail in seven to right months. within the middle and late stages, the water should be kept to make sure an honest appetite for fish so on achieve rapid climb .

At present, there are two sorts of artificial diets in [url=https://www.feed-pelletmachines.com/news/make-tilapia-fish-feed.html]tilapia feed[/url], one is ordinary pellet and therefore the other is extruded feed pellets. 0.75 to 1 kilograms tilapia feed produced by fish feed extruding machine can feed 0.5kg tilapia. within the production of ordinary pellets, the tempering temperature should be controlled between 80℃~95℃. When producing extruded tilapia feed, adopt superfine grinding process, quite 80% of the fabric can pass 80 mesh screen, the produced feed has good looking appearance. Moreover, the feed has little wear and tear on the extruding machine, which may prolong its service life.
