What are the ecological importance of tilapia?
In many systems, tilapia can serve the important limnological role of circulating nutrients by consuming abundant algae and detritus and improving water clarity (Lowe-McConnell, 2000) . Conversely, in some ecosystems the consumption of algae releases nutrients back into the system causing eutrophication . …
Are tilapia fish predatory?
Unlike carnivorous fish, tilapia can feed on algae or any plant-based food. This reduces the cost of tilapia farming, reduces fishing pressure on prey species, avoids concentrating toxins that accumulate at higher levels of the food chain, and makes tilapia the preferred “aquatic chickens” of the trade.
Is a fish an omnivore?
The majority of marine fish are omnivorous, which means they need to eat both meat- and plant-based foods. One easy option for omnivorous eaters is commercial fish food, such as flakes or pellets.
Which is an economic importance of farming with tilapia?

Are tilapia vegetarians?
Tilapia eat mostly plant-based diets which make them incredibly inexpensive to farm. Their vegetarian diet also takes the pressure off of wild caught prey species and eliminates the risk of the fish accumulating high levels of toxins like mercury that concentrate in fish higher up in the food chain.
What is the scientific name of tilapia?

Why is tilapia considered a aquaculture fish?
Aquaculture. Unlike carnivorous fish, tilapia can feed on algae or any plant-based food. This reduces the cost of tilapia farming, reduces fishing pressure on prey species, avoids concentrating toxins that accumulate at higher levels of the food chain and makes tilapia the preferred “aquatic chickens” of the trade.
What do tilapia eat in the wild?
Biology and Life History: In the wild, tilapia are found in turbid rives and lakes. They are herbivores who feed mainly on plankton, algae, and other vegetable matter. As a result of their feeding patterns they do not accumulate toxins in their bodies.
What is the lifespan of a tilapia fish?
Description: Tilapia are a hardy, fast growing fish, that can live up to ten years and reach ten pounds in weight. Tilapia are shaped like a sunfish or crappie and are easily identifiable by the interrupted lateral line characteristic of the Chiclid family of fishes.
