It is important to get the breeders in pairs. The recommended number is 20 pairs per 200 square feet. The breeders reproduce within 10 weeks to provide fingerlings. When transferring the fingerlings or breeders, ensure the pond water is at the same temperature as the water in the fish container.
Can tilapia reproduce in a pond?
Breeding of tilapia is conducted in ponds, tanks or hapas. The stocking ratio for females to males is 1-4:1 with 2 or 3:1 being the most common. The popular hapa-in-pond spawning system in Southeast Asia uses 100 g brood fish stocked at 0.7 kg/m2.
How do you get tilapia to breed?
How do you get them to breed? Just like you keep the water cold and the lights off for calm tilapia, you can use warm water and light as an “on switch.” Both the warmth (75–85 degrees) and the light cycle (at least 12 hours a day) act as environmental cues to your fish that it’s time to make fry.
How do you set up a tilapia pond?
Apply chicken manure on the pond bottom with water depth of about 6 centimeters at the rate of one kilo for every 10 square meters. Fertilize the pond once a month to insure good production of algae. You can either use commercial fertilizer or organic matter like manure, compost, ipil-ipil leaves, etc.
How fast do tilapia grow in a pond?
To answer your question with a number, it takes 240 days, or 34 weeks for food grade tilapia to reach a 16 to 20 ounce harvest size. Food grade tilapia are simply those tilapia that exhibit the fastest rates of growth.
How fast do tilapia multiply?
But, how quickly do tilapia reproduce? If the conditions are right, one female tilapia will spawn between 4 weeks to 4 months, depending on the species. Even if the survival rates are very low, you’ll still get a tank full of tilapia fry within a very short period of time.
How deep should a tilapia pond be?
But they prefer a water temperature of 82 to 86 degrees Fahrenheit, as they grow slowly in 68 degree F water and may die when the water temperature drops to 50 degrees F. Many tilapia ponds average one-half acre or larger in size, but are only 3 to 6 feet deep, so a large backyard or acreage is a necessity.
Are tilapia easy to breed?
Just one female will typically produce about 200-1000 eggs per spawn, and she’ll spawn every 4-5 weeks or so if conditions are decent enough in the tank (“decent” is pretty easy for tilapia).
How many times do tilapia lay eggs in a year?
© Shutterstock / konmesa – Tilapia farming in Thailand Mature females can lay eggs every three to four months (from the 12th week in the case of the Nile tilapia). They lay their eggs in nests made by the males, then carry the fertilised eggs in their mouths until they hatch.
Can you cross breed tilapia?
And, as if it can’t get any stranger, tilapia can even develop as hermaphrodites, with both male and female reproductive organs.
How Big Should a tilapia pond be?
There is no restriction on pond size, but for ease of management and economical operation, shallow (3 to 6 feet), small (1 to 10 acres) ponds with drains are recommended. Draining is necessary to harvest all of the fish. A harvesting sump is needed to concentrate the fish in the final stage of drainage.
What do tilapia eat in ponds?
Tilapia will eat many of the common types of filamentous algae, blue green algae, rooted plants and even twigs and other organic debris. They are very efficient consumers. When stocked at the appropriate rates into your pond, the Tilapia can be very effective at dramatically reducing seasonal plant material.
How much space does a tilapia need?
Most people start with a fish tank of at least 500 liters. This should give you approximately 130 gallons which allow enough room for between 20 and 40 full grown tilapia. You can always expand the tank later.
What makes tilapia grow faster?
Tilapia will grow really fast if the water is in the mid to high 80’s, from fry to plate in about 6-7 months. Cooler water will take longer. Simply, the more fish you have in a tank the faster you must remove waste water! They will need more oxygen as the densities increase.
What do baby tilapia eat?
What do Baby Tilapia Eat? Baby tilapia are called fry and are usually 0.25 – 0.75 inches long. Fry usually focuses on foods like detritus, neuston (organisms that float on the water), zooplankton, and polyplankton. They can also be offered fine fish pellets or fish meal like bone meal to help them grow.

Don’t forget that fresh, locally farmed tilapia is always a welcome find at the farmers market or on the menus of neighborhood restaurants.
How do you control the reproduction of tilapia in ponds?
To control the reproduction of residual females in the population, a small predator (10-50 g H. fasciatus) is used in the production ponds at a low ‘stocking rate (3-10 percent of the weight of tilapia stocked).
How many months can tilapia be harvested?
Male tilapia are stocked at 1-3 fish/m2 and grown to 400-500 g in five to eight months, depending on water temperature. Normal yields range from 6-8 tonnes/ha/crop but yields as high as 10 tonnes/ha/crop are reported in northeast Brazil, where climate and water quality are ideal.
Where do tilapia lay eggs?
Substrate spawners lay eggs in a pit dug in the bottom of the lake or pond. The eggs are aerated and guarded by the parents. Mouth brooders may lay their eggs in pits, then take them into the mouth and keep them there till the young hatch.
