Application of Green Economy in Aquaculture
Green economic development is a development model that combines economic growth and environmental quality improvement. The green economy is a resilient economic growth that does not exclude environmental problems. This green economy prioritizes low-carbon development and pays attention to its social impacts.
The green economy concept is an economic concept that takes into account economic growth and prevention of environmental damage. The green economy also includes three policy areas, namely the scope of economic development, social development, and environmental protection. The goal of the green economy is to achieve balanced economic growth by maintaining ecosystem balance and reducing negative impacts on the natural environment.

In aquaculture the concept of green economy needs to be applied because in principle the output of aquaculture activities in addition to fish production there is also waste released. Waste production from fish farming will be more if aquaculture activities are carried out intensively. One example of aquaculture business activities in floating nets, if fish farming activities in floating nets are not controlled then this will cause a decrease in water quality in the public water environment.
Then the negative impact of fish farming on the environment is water pollution due to a decrease in water quality from debris and inedible fish feed. Poor water quality can be caused by low oxygen levels and high ammonia levels.
Fish farming that is not done properly, namely not applying the principles of good fish farming methods, will have other negative impacts, such as fish farming carried out together with poultry livestock whose poultry cages above the pond will make the aquatic environment polluted. This water environment is unhealthy because there are remnants of poultry feces that can pollute the fish pond. In addition, integrated fish farming with poultry can also cause social impacts due to the unpleasant odor generated from these activities.

Seeing from the explanation above, the concept of aquaculture based on the green economy needs to be applied so that fish farming business activities can be sustainable, one of the efforts is by way of:
1. The application of good fish farming methods, namely by paying attention to the safety of fishery products by controlling the environment, sanitation, feed, medicines, and chemicals used in the fish farming process.
2. Fish farming technology with a recirculation system that aims to keep the level of water quality in good condition. In addition to maintaining optimal water quality, recirculation system fish farming technology is also useful for saving water usage for fish farming media.
3. Fish farming technology with a biofloc system is an environmentally friendly fish farming technology because the principle of fish farming with this biofloc system is to minimize the waste generated from fish farming activities by using microorganisms that can help break down organic waste into materials that are not harmful to fish and can also be used as safe feed for cultivated fish.
4. Fish farming technology with vegetable or fruit plant cultivation. one example is fish farming in a bucket with kale plants. this fish farming technology is an environmentally friendly technology because fish farming carried out with these plants will have a positive impact on the surrounding environment with the kale plants besides being consumable can also provide benefits to the freshness of the air around the cultivation environment.
The aquaculture technology mentioned above is a fish farming technology that can generate economic benefits, but its implementation needs to be controlled and monitored so that the negative impacts resulting from aquaculture activities do not occur.
