Everything You Need to Know About Feeding Shing Fish (Stinging Catfish)

Shing fish, commonly known as the stinging catfish (scientific name: Heteropneustes fossilis), is a popular freshwater species found in South and Southeast Asia, particularly in countries like Bangladesh, India, Nepal, and Myanmar. This species is known for its high nutritional value, medicinal properties, and the ability to survive in adverse conditions. In recent years, the commercial farming of shing fish has become more widespread due to its high market demand and profitability. One of the most crucial factors for successful fish farming is understanding the dietary needs and feeding habits of the fish.

In this blog, we’ll explore the types of food that are most suitable for shing fish, how to properly feed them, and what to consider when developing a feeding schedule for these fish to ensure optimal growth and health.

1. Natural Habitat and Feeding Behavior of Shing Fish

Before diving into the specifics of their diet, it is essential to understand the natural habitat of shing fish. They are typically found in shallow, slow-moving waters such as ponds, ditches, swamps, and rice paddies. They are highly adaptable and can survive in low-oxygen environments due to their specialized respiratory system.

Shing fish are omnivores, meaning they consume both plant and animal matter. In the wild, their diet includes small insects, crustaceans, plankton, larvae, and detritus (decaying organic matter). They are also scavengers, feeding on decomposing material at the bottom of ponds. This flexible diet helps them thrive in a variety of environments.

2. Types of Food for Shing Fish in Captivity

To ensure that shing fish raised in farms or aquariums grow well and stay healthy, providing a balanced diet that replicates their natural feeding habits is crucial. Below are the key types of food that can be given to shing fish:

a) Natural Foods

In controlled environments like fish farms, shing fish can still be fed natural foods that they would typically find in the wild. These foods include:

Zooplankton: Microscopic animals that float in water and are a natural food source for fish.
Small Crustaceans: Shrimp, crabs, and other tiny aquatic organisms can be provided.
Insect Larvae: The larvae of flies, mosquitoes, and other insects are a good source of protein.
Worms: Earthworms, bloodworms, and tubifex worms can be offered as a protein-rich food source.
Aquatic Plants: Algae, water hyacinths, and duckweed are some examples of plant matter that shing fish will consume.

Natural food should be regularly supplemented to mimic the natural conditions as much as possible. However, relying solely on natural foods may not provide the fish with all the nutrients they need for optimum growth.

b) Artificial Feed

Due to the growing demand for commercial fish farming, specially formulated feeds have been developed for different types of fish, including shing fish. These feeds are designed to be nutritionally complete and ensure faster growth. Some popular options include:

Pelleted Fish Feed: Commercially produced fish pellets are available in various sizes and formulations depending on the stage of growth of the fish. These pellets are nutrient-rich and can include proteins, fats, vitamins, and minerals.
Protein-Rich Diets: Shing fish require a diet that is high in protein for growth, especially during their juvenile stages. Fish meal, soybean meal, and other protein-based feeds can be included in their diet.
Floating vs. Sinking Pellets: Depending on the behavior of the fish, both floating and sinking pellets can be provided. Shing fish tend to feed near the bottom of the water, so sinking pellets are often more appropriate.

c) Homemade Feed

Some fish farmers prefer to make their own fish feed using readily available ingredients. Commonly used items include:

Rice Bran: Rice bran is a common component of homemade fish feed and is a good source of carbohydrates.
Fish Meal: This can be ground into a fine powder and mixed with other ingredients to provide a protein-rich diet.
Vegetable Waste: Finely chopped vegetable scraps can also be included in the diet as a source of fiber and essential nutrients.

While homemade feeds can reduce costs, it’s important to ensure they meet the nutritional requirements of the fish.

3. Feeding Frequency and Quantity

The amount and frequency of feeding play a critical role in the growth and overall health of shing fish. Overfeeding can lead to waste buildup in the pond or tank, while underfeeding can stunt growth and affect the fish’s immune system. Here’s a general guideline for feeding frequency:

Juveniles (Hatchlings to Fingerlings): Young shing fish require frequent feeding as they grow rapidly during this stage. Feed them small amounts 3-4 times a day.
Sub-Adults: As they grow older, you can reduce feeding to 2-3 times a day, ensuring they receive enough nutrients to continue growing.
Adults: Fully grown shing fish only need to be fed 1-2 times a day, as their growth rate slows down. Be sure to provide a balanced diet to maintain their health.

The exact quantity of feed depends on the number of fish, their size, and the type of feed being used. As a general rule, offer as much food as the fish can consume in 10-15 minutes, then remove any uneaten food to prevent water contamination.

4. Water Quality and Its Impact on Feeding

Feeding the fish is not just about providing the right food. Maintaining good water quality is essential for the fish to digest and utilize the food properly. Poor water conditions, such as low oxygen levels, high ammonia, or an imbalanced pH, can negatively impact the fish’s appetite and growth.

Regular water changes, aeration, and monitoring of water parameters (such as pH, ammonia, and nitrite levels) should be part of your feeding routine. A healthy aquatic environment will support better digestion and nutrient absorption, leading to healthier, more robust fish.

5. Common Feeding Problems and Solutions

a) Overfeeding

Overfeeding can cause food to accumulate at the bottom of the pond or tank, leading to the production of harmful gases like ammonia, which can stress or even kill the fish. Solution: Always feed the fish small amounts at a time, and remove any leftover food after feeding.

b) Underfeeding

Fish that are underfed may exhibit slow growth and become more susceptible to diseases. Solution: Ensure that all fish in the pond or tank are getting enough to eat. It may help to distribute the food in several locations.

c) Poor Water Quality

Dirty water makes it difficult for fish to feed properly and can cause them to lose their appetite. Solution: Maintain good water quality with regular monitoring and water changes.

Conclusion

Feeding shing fish requires a balanced approach that includes providing the right types of food, ensuring proper feeding frequency, and maintaining good water quality. Whether you’re raising shing fish in a commercial farm or in a home aquarium, understanding their dietary needs is key to achieving optimal growth and health.
