What Do Sturgeons Eat?

The sturgeon, this majestic fish with a prehistoric past, is a fascinating species to observe in a pond or small lake. But for it to thrive, it is essential to understand its dietary needs.

In this article, we will explore the natural diet of the sturgeon and suitable alternatives for garden ponds and small lakes.

The Natural Diet of the Sturgeon

In the wild, the sturgeon is a benthic fish, which means it primarily feeds at the bottom of the water. Thanks to its sensory barbels located under its snout, it easily detects its food, even in murky waters. Its diet mainly consists of:

• Crustaceans: shrimp, crayfish, and other small benthic crustaceans.
• Worms: such as bloodworms and tubifex worms.
• Mollusks: freshwater snails, mussels, and other shellfish.
• Small fish: occasionally, the sturgeon may catch fry or small fish.
• Organic matter: it sometimes ingests organic debris rich in nutrients.

These natural sources are rich in protein, necessary for the growth and development of the sturgeon. However, in a pond or small lake environment, it is often difficult to replicate this exact diet. Fortunately, alternatives exist.

Feeding Sturgeons in Ponds and Small Lakes

In garden ponds or small lakes, it is essential to provide suitable food to compensate for the absence of their natural prey. Here are the best alternatives:

1. Specialized sinking pellets

Pellets specifically designed for sturgeons are the best option to ensure a balanced diet. They are formulated to meet their nutritional needs in proteins, lipids, and vitamins, while being easy to digest.

• Aquifood Esturgeon: This specialized food contains high-quality sinking pellets rich in essential nutrients. It is ideal to support the growth and well-being of your sturgeons.
• Ichi Food Esturgeon: With its premium composition and selected ingredients, this alternative is perfect to ensure optimal health for your fish while limiting waste in the pond.

2. Live and frozen worms

Bloodworms and tubifex worms, whether live or frozen, are an excellent option to vary their diet. They mimic the natural prey of sturgeons and are particularly appreciated by these fish.

3. Small fish or pieces of fish

Under controlled conditions, you can also offer small fish or pieces of raw fish (boneless) to complement their diet, especially in large lakes.

When and How to Feed Your Sturgeons?

Good timing and an appropriate method are essential to avoid waste and ensure optimal feeding.

1. Meal times: Feed your sturgeons early in the morning or in the evening, when the temperature is ideal.
2. Frequency: In summer, when the water is above 12°C, feed them 2 to 3 times a day. In winter, reduce feedings or even stop temporarily if they are inactive.
3. Method: Use sinking pellets that quickly reach the bottom, as sturgeons do not feed at the surface. Leave the pellets in a specific spot to get your fish used to coming there to feed.

Foudebassin Tip: Install an automatic feeder to ensure regular feeding, even when you are away.

Mistakes to Avoid

• Floating food: Sturgeons do not feed at the surface. Using floating food can lead to deficiencies.
• Overfeeding: Giving too much food can harm water quality and promote algae growth.
• Inappropriate feeding: Avoid non-specialized foods or those high in carbohydrates, which are not suitable for their metabolism.

Conclusion

The health and longevity of your sturgeons largely depend on their diet. By respecting their specific needs and offering them suitable solutions, such as Aquifood Esturgeon or Ichi Food Esturgeon, you ensure their well-being while maintaining a harmonious pond or lake.
