# Species: Growth Rate Info: Growth Rate Information

The following Charts will answer most of your questions about tilapia fingerlings and how they grow.

Lets suppose you put the following groups of 1,000 fish, 10 grams average for each tilapia fingerling, in a series of ponds of 1/10 Hectare each or cages 3 meters. x 2 meters by 1.5 meters in depth in at least a one hectare pond. You then feed them twice a day with a 32 percent Protein feed for 110 days at an average temperature of 85 degrees Fahrenheit and then harvest the resulting fish.

1. In pond or cage number One you put 1,000 Chocolate Hybrids*

2. In pond or cage number Two you put 1,000 Pennyfish*

3. In pond or cage number Three you put 1,000 Red Knight Hybrids*

4. In pond or cage number Four you put 1,000 red tilapias from where-ever.

5. In pond or cage number Five you put GMT yy male fingerlings

6. In pond or cage number Six you put sex reversed t. nilotica fingerlings

You would be able to harvest according to the following schedule:

In one hundred and ten days;

Pond or cage One with the Pennyfish* in 110 days you could harvest 1,000 Pennyfish* (six hundred gram) whole fish or a total of 600 kilograms, restock it and do the same 3 times in a year for a total yearly production of 1,800 kilograms or 3960 pounds per year. You would realize up to 42 percent skinless boneless fillets which is 1,663 pounds of skinless boneless fillets per year. The parent stock breeders for the Pennyfish* is obtained from Tilapia Aquaculture International. Pond or cage Two with the Chocolate Hybrids* in 110 days you could harvest 1,000 (one thousand gram fish) which is 1,000,000 grams or 1,000 kilograms of whole fish and you could restock the pond three times a year and harvest 3,000 kilograms of whole fish. With a 44 percent yield you would have 1,320 kilograms of skinless boneless fillets per year per pond or cage. The parent stock breeders for the Chocolate Hybrid* is obtained from Tilapia Aquaculture International.

Pond or cage Three with the Red Knight Hybrids* in 110 days you could harvest 1,000 (550 gram fish) which is 555,000 grams or 555 kilograms of whole fish and you could restock the pond three times a year and harvest 1,650 kilograms of whole fish per year. With a 40 percent yield you would have 660 kilograms of skinless boneless fillets per year per pond or cage. The parent stock breeders for the Red Knight* is obtained from Tilapia Aquaculture International.

Pond or cage Four with the red tilapias from where-ever in 110 days you could harvest 1,000 (175 gram fish) which is 175000 grams or 175 kilograms of whole fish and you could restock the pond three times a year and harvest 525 kilograms of whole fish per year. With a 32 percent yield you would have 168 kilograms of skinless boneless fillets per year per pond or cage. These red tilapias are the ones sold in Israel, Jamaica and in Florida and Georgia.

Pond or cage Five with the GMT tilapias in 110 days you could harvest 1,000 (200 gram fish) which is 200,000 grams or 200 kilograms of whole fish and you could restock the pond three times a year and harvest 600 kilograms of whole fish per year. With a 32 percent yield you would have 192 kilograms of skinless boneless fillets per year per pond or cage. These tilapias can be obtained from the GIFT group. Pond or cage Six with the sex reversed male tilapia nilotica in 110 days you could harvest 1,000 (180 gram fish) which is 180,000 grams or 180 kilograms of whole fish and you could restock the pond three times a year and harvest 540 kilograms of whole fish per year. With a 32 percent yield you would have 172.8 kilograms of skinless boneless fillets per year per pond or cage. These fingerlings can be obtained from a number of growers almost anywhere. Now to make the comparison Easier lets look at the actual yearly yield in whole fish and then in pounds of skinless boneless fillet per year with the same investment per pond or cage in feed**, time, and space. We are also ignoring cost of production of fingerlings and mortality, which are best in the three varieties of tilapias we supply.

YIELD IN $ US OF EACH FINGERLING TYPE PER YEAR ACCORDING TO ABOVE

This chart is a stacked chart, that is the measurable elements are stacked even though the total weight in red, of fish is not the same as the yield of fillet or the total revenue for the fillet it is stacked as if you could add them together, I plan to fix this as soon as I have time. It still illustrates the vast differences between the fingerlings accurately.

The following chart more accurately reflects the differences. Here is a recent evaluation of the quality of the Fingerlings produced by my breeders compared to the rest.

YIELD IN DOLLARS PER YEAR FROM FILLET SOLD AT $7.00 PER KILOGRAM PRESENTED AS A PIE CHART

PICK YOUR PIECE OF THE PIE

All other known tilapia breeds or fingerlings provide yields lower than the three used in the number 4. 5, and 6 of the above chart.

If your are currently growing any of the three tilapia fingerlings on the right half of the chart and are making a profit or at least trying to, please consider that your Gross Returns per year between the Pennyfish* and the best any one of the Fingerlings on the right half of the chart are many times in favor of the Pennyfish*

Important info: Just weighted one of the Chocolate Hybrids last weighted on Sep 15 at 3.3 pounds and it now weights 4 pounds on Nov 28, 1998. I brought the fish to my farm and have been keeping it with one other Chocolate Hybrid in a 8 ft x 3 ft x 1.4 ft deep tank and have only fed it about once every two days. Poor Fish.
