Ducks do eat hydrilla, especially when there is not much food available to them.

Ducks are omnivores and they eat mainly seeds, grains and nuts. So it’s not surprising that they will take the opportunity to get the roots of hydrilla when the plants are dying.

What Is Hydrilla?

Hydrilla is a plant that grows in lakes, reservoirs, and ponds. It is considered an invasive weed because it crowds out native plants. It forms dense stands of long slender leaves on top of thick stalks that grow just below the water surface. The leaves look like green grass blades.

They grow to about 2 inches in length. Leaves grow in whorls at the nodes on the plant stalks. Hydrilla has no flowers or seeds; it reproduces by sending out new shoots at the nodes on its stalks. The reproductive process occurs underwater so it is difficult to monitor, which helps spread the plant quickly. The shoots can grow a foot or more within a single growing season, spreading hydrilla throughout a lake system.

Will Ducks Eat Hydrilla?

Ducks will eat this floating weed as they would other aquatic plants and water weeds while they are swimming, floating and diving for food near the water’s surface.

They also enjoy this plant when they are grazing in deeper water along the bottom of lakes, ponds, and reservoirs where it is growing over submerged weeds and aquatic vegetation that grows below their normal foraging level where they cannot reach it with their bills. Their long necks allow them to graze far below the surface of deeper water where there is plenty of food variety for them to enjoy with all of those divergent tastes that ducklings have.

Where Can You Find Hydrilla?

Hydrilla is found in shallow water but it can also grow in deeper water as well. It grows best in lakes and ponds but it can also grow in reservoirs and slow moving rivers, including canals and drainage ditches. It tends to take over parts of the lake or pond system where it is able to spread.

It cannot grow on shorelines that are rocky or hard enough for the plant’s root system to get a hold on. If this type of shoreline exists, it will kill the hydrilla or at least slow its growth considerably as its root mass will rot away with prolonged contact with an unsuitable substrate.

Is Hydrilla Good For Ducks?

Hydrilla is fine for ducks to eat or have in their pond. Hydrilla is a nutritious plant that is rich in protein as well as vitamin A and C. It will provide your ducks with essential vitamins and minerals they need to live long and healthy lives. Further, hydrilla is quite nutrient rich so you’ll be providing additional nutrients to your ducks over and above what they’d find to eat growing naturally in your environment.

As such, your ducks will be even healthier. In other words, hydrilla is good for ducks.

Hydrilla Health Risks For Ducks

Hydrilla is obviously a plant that can cause problems for ducks and other animals. Baby ducks often end up with leg injuries after they get entangled in the vines of hydrilla.

Ducks will also often get injured by falling or falling from the surface of water onto hydrilla roots or submerged hydrilla.

What Should Ducks Eat?

Ducks are omnivorous, o they can enjoy a pretty diverse diet, however, they need to be supplemented with some foods to fulfill their nutritional needs.

The types of food that ducks can eat are:

Vegetables: Beans, carrots, corn, cucumber, lettuce, peas and cabbage. Things you should take into account is that cucumbers and beans should not be given whole; the seeds inside can cause problems for the digestive system of the duck. Also, carrots should only be fed in small amounts so that they don’t get too many calories from their diet. The rest of the food items should not be fed in excess either because then your duck will gain weight and some may have problems digesting all those rich foods. 

Grains/seeds: Barley, oats, wheat bran, or ryegrass seeds (but only if they are milled or cracked). Foods rich in fat/oils: Sunflower seeds, corn, soya beans, and maize.

They can enjoy any kind of vegetable oil in moderation. Foods rich in protein: Any kind of meat like beef, fish, and dried insects (insects must be soaked in water to make them more digestible). Foods rich in minerals/vitamins: Soya beans (but only if they are milled or cracked), carrots, parsley, and lettuce (they are a good source of Vitamin A).

Ducks also enjoy eating different kinds of rice. Barley rice is perfect for your ducks because it’s an important source of energy for your ducks in winter time when there is less green food available for them.

The ideal diet for your duck should consist of a combination of the items I listed before:

You must not offer duck just one type of food from the list at any one time. This will lead to a deficiency of certain important nutrients.

The main reason why the ducks live very long in the wild is that they eat a lot of variety and not just one type of food.

Ducks must be fed at least three times a day, although if they have free access to water all day long they can be fed only twice.
