Introduction Worldwide harvest of farmed tilapia has now surpassed 800,000 metric tons, and tilapia are second only to carps as the most widely farmed freshwater fish in the world. The Nile tilapia (O. niloticus) was one of the first fish species cultured.

What does a tilapia fish look like?

Feed the fry at a rate of 10 – 30% of body weight per day, at least four times a day for 21 – 28 days. Tilapia males are preferred for culture because they grow faster than females. Females use considerable energy in reproduction and do not eat when they are incubating eggs.

How much food do tilapia need to survive?

In general, tilapias use natural food so efficiently that crops of more than 2,700 pounds of fish per acre (3,000 kg/ha) can be sustained in well-fertilised ponds without supplemental feed. The nutritional value of the natural food supply in ponds is important, even for commercial operations that feed fish intensively.

How long can tilapia live with pathogens?

Critical point: The length of time that a tilapia can survive with a pathogen is directly related to it’s age, size and immune system. Tilapia fry and fingerlings weighing one gram or less have no resistance to pathogens whatsoever and will die almost immediately after exposure, whereas larger tilapia can survive for much longer.

What does tilapia look like?

Tilapia just looks like a regular fish. It is a very popular fish, and is very good for the human body. When baked, this fish will be very nutritious and tasty.

When to change the feeding mode of tilapia cultivation?

After two to three 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 in stead of animal manure.

What does a tilapia need to live?

Every tilapia needs the same things to live, and the only difference between the large commercial farm, and the backyard farm, are the methods used. In the end, the results are all that matter. The level of creativity that you use to get there is up to you, and part of the personal satisfaction that you’ll get from tilapia farming.

Does tilapia have an expiration date?

Many people like tilapia better than other fish, as it does not have a very fishy taste. Regarding the shelf life of the fish, it lasts for a relatively shorter period if not cared for or stored properly. Fish, along with other proteins, does not have an expiration date, but rather, has a sell-by date.

Do tilapia have pathogens?

Not to mention the fact that the incubation period for most pathogens, is longer than it takes for the tilapia to grow to harvest size. So it might not be clear by looking at the fillets if they still had the disease at the time of harvesting and processing. Pathogens are all-around bad news in tilapia farming.

What are the characteristics of Nile tilapia?

The jaws have conical teeth. Typically, tilapia have a long dorsal fin, and a lateral line that often breaks towards the end of the dorsal fin, and starts again two or three rows of scales below. Some Nile tilapia can grow as long as 2.0 ft.

What are the biological and environmental factors that affect tilapia?

These factors are biological factors directly related to the tilapia and environmental factors related to the water body and culture system. Age: What is true for fish in general is also true for tilapia in particular: Younger fish are more susceptible than adults.

Why are tilapia so resistant to disease?

Tilapia tolerate adverse water quality and other stressors better than most commercial aquaculture species. Because stress and environmental quality play such important roles in the disease process, tilapia are labeled as being very “disease-resistant.” This means that in the presence of pathogens, tilapia are slow to break with disease.

Are tilapia more susceptible to parasites?

Age: What is true for fish in general is also true for tilapia in particular: Younger fish are more susceptible than adults. For example, newly hatched and juvenile tilapia are extremely sensitive to protozoan parasites. Particular attention to parasite screening is necessary at these stages to ensure maximal survival.
