Large jar filled with water, oxygen, food and aquatic plants and animals.
• Oxygen/oxygen pump.
• Fish food.
• Aquatic plants/Producers provide O2 during photosynthesis.
• Aquatic animals/Consumers release CO2 for the process of photosynthesis.
• Decomposers are also important for natural cleaning of the aquarium.
Creating a self-sustainable artificial aquatic ecosystem involves careful design and consideration of various ecological factors. Such systems are often called closed aquatic ecosystems or aquaponics systems. Here’s a general guide on how to create a self-sustainable artificial aquatic ecosystem:
• Select a Suitable Container: Choose a container or tank large enough to support a variety of aquatic life. The size will depend on the scale of your project.
• Water Circulation or pump: Install a water circulation system to ensure adequate oxygenation and nutrient distribution. A pump and filter system can help maintain water quality.
• Aquatic Plants for oxygen: Introduce aquatic plants, such as water lettuce, water hyacinth, or other submerged plants. These plants will contribute to oxygen production and nutrient cycling.
• Fish or Aquatic Animals: Introduce fish or other aquatic animals. Fish waste will serve as a nutrient source for the plants, creating a natural symbiotic relationship. Common choices include tilapia, goldfish, or koi.
• Feeding: Feed the fish in moderation, and let the fish waste serve as a nutrient source for the plants. This creates a closed nutrient cycle.
• Lighting: Provide appropriate lighting for both plants and, if needed, for the growth of algae. Natural sunlight or artificial lighting can be used, depending on the setup.
• Regular Pruning and Harvesting: Prune the plants and harvest any edible parts regularly. This helps maintain the balance in the ecosystem and prevents overgrowth.
• Monitoring: Regularly monitor the ecosystem’s health and make adjustments as needed. This may include adding or removing organisms, adjusting nutrient levels, or addressing any issues with water quality.
Remember that creating a self-sustainable aquatic ecosystem requires careful planning and ongoing management. It’s essential to understand the specific requirements of the organisms involved and to make adjustments as the ecosystem evolves.
