What do freshwater fish eat?

The diet of a freshwater fish depends on its habitat, species, as well as the ecosystem they live in. Freshwater fish can carry a carnivore, herbivore, or omnivore diet depending on their species.

Why can’t freshwater fish live in saltwater?

Freshwater fish can’t live in saltwater because it is too salty for them. The water inside their bodies flows out and as a result they die from dehydration.

Why are freshwater animals going extinct?

Freshwater animals are going extinct due to the creation of man-made elements that block migration routes for fish and disrupt habitats. The water withdrawal for human use also shrinks and degrades habitats as well as the draining of wetlands for development depletes habitats. Other reasons include overexploitation, pollution, and global warming.

How can we protect freshwater fish?

We can protect freshwater fish by establishing multiple solutions. These solutions include restricting the construction of dams and establishing protected wetlands. Other solutions to protect freshwater fish are regulating water withdrawal for human use and incentive for farming businesses to reduce the use of pesticides.

How can we protect endangered species?

We can protect endangered species by learning more about the endangered species around our surrounding communities, minimizing the use of pesticides, and reducing our consumption of water within the home. Other ways to protect endangered species include recycling, not littering, and not purchasing products that are made from endangered animal species.
