In intensive shrimp and fish farming, only 25% of the protein is absorbed and the remaining 75% is discharged into the environment. Therefore, aquaculture is often associated with the problem of environmental pollution. However, there are many aquaculture activities that focus on protecting natural resources and the environment, ecological benefits in addition to socio-economic benefits.
Classification of aquaculture
1. Organic sea grapes
Sea grapes are grown in a saltwater aquaponic system. Nutrient-enriched water from the fish culture system is fed into the seaweed system, where the nutrients are broken down by nitrogen-fixing bacteria into nitrates that are then used by the plants. The water is then circulated back to the fish farming system. In this system, sea grapes absorb about 70% of nutrients. The fish species raised by the company are grouper, red tilapia and lobster. In addition to sea grapes, the company also grows sea-blites.

2. Safe Oysters
After a period of testing oyster farming and choosing suitable locations in Vietnam, Singapore and Indonesia, the company has built a safe oyster production model. Oysters are a highly demand food with high nutritional value, bringing many health benefits. However, the technical barrier in consuming and exporting oysters is the issue of food safety due to microorganisms (Vibrio/Norovirus) or toxins in some algae species that can cause adverse effects on human health. Therefore, it is necessary to produce, harvest, process and trace the origin of oysters to ensure food safety standards. The company provides seeds, technology and buys back commercial oysters to farmers. The company is also responsible for processing and marketing safe oyster products.

3. Sustainable lobster production
Currently, the lobster farming industry relies on natural seed because it cannot produce the seed at a commercial level yet. The company is working with partners in Vietnam, Singapore, Indonesia and China to try-out lobster breeding. Lobster larvae are given natural food, artificial food and created an environment closest to the natural environment. Hopefully, with the participation and strengthen of partners, lobster seeds will soon be produced on a commercial scale.
Lobsters are raised to diversify products for the company and use oyster products that do not meet commercial standards for human consumption. In addition, the company also gradually builds industrial food formulas for lobster development stages. This method helps to minimize the exploitation of natural food for lobster farming, helping to produce more sustainable lobsters.

4. Marine ecosystem – ReefMax
Cooperate with Singaporean company Jireh Marine to continue developing systems and products under the REEFMAX brand https://jirehmarine.com/product-tag/reefmax/. These products are food and nutrients for corals and marine fish such as oyster eggs, and gel, flakes, block feeds. Especially live, dried and frozen copepod products.
