Myth: Shrimp farms are endangering mangrove environments. Let's dive in.
What is a mangrove & why do mangroves matter?
Mangroves are salt-tolerant shrubs or trees also called halophytes that grow in tropical and subtropical coastal wetlands. They usually have complex stilt or prop roots that allow them to anchor into the substrate beneath the water, while most of the plant is on top of the water surface. Their roots are adapted to low oxygen levels in muddy waters, and high wave action on the top half of the plant.
Mangrove forests provide valuable ecosystem services including preventing erosion, providing habitat for myriad fisheries species, protecting coastal communities from extreme weather events, and storing large reserves of blue carbon, thus mitigating global climate change.
Unfortunately, mangrove deforestation and forest fragmentation has been occurring at an alarming rate in many places around the world. Purposeful deforestation and fragmentation are caused by the conversion of these wetland areas for agriculture, aquaculture. Incidental deforestation is also happening as a byproduct of global climate change with rising sea levels and toxic pollution. Mangrove forests worldwide are in danger, but the largest decline has been documented across coasts in Southeast Asia.
Industrial methods of unsustainable commodity shrimp farming and other aquaculture like basa, tilapia and barramundi have displaced and destroyed natural mangrove environments in the quest to intensively farm shrimp in the cheapest way. Up to 70% of Indonesia’s mangrove forests have been damaged or degraded by shrimp farming.
In the face of mangrove deforestation, many countries, NGOs and private companies have dedicated extensive research, money, and time into finding better ways to farm shrimp that also increase mangrove conservation and replanting efforts. Governments and nonprofits are working with producers, NGO partners, industry, and governments to create new frameworks and tools for environmentally sustainable production of shrimp and other aquaculture ventures. These projects aim to plant new mangroves while scaling integrated shrimp farming systems that allow the ecosystem to flourish and provide unparalleled ecological benefits.
Large-scale conservation efforts and monitoring efforts of these environments have made a significant impact in mangrove numbers worldwide. For example, rehabilitating and conserving mangroves in Indonesia could benefit 74 million coastal people and can potentially contribute to the national land-sector emissions reduction of up to 16%. Supporting these projects and initiatives is imperative for creating long-term financially sustainable solutions to mangrove reforestation and conservation.
Here are a few examples of projects in Vietnam and Indonesia where we will be sourcing from that combine mangrove restoration and shrimp farming, along with some available data on their environmental success:
- Mui Ca Mau Biosphere Reserve:
Located in the southernmost province of Ca Mau in Vietnam, this project focuses on sustainable shrimp farming integrated with mangrove restoration. According to a study published in the journal "Ecological Engineering," the project has shown positive environmental outcomes, including increased biodiversity, improved water quality, and carbon sequestration. It reported a 70% reduction in chemical inputs and a decrease in disease outbreaks compared to conventional shrimp farms.
- U Minh Ha National Park:

In the Mekong Delta region of Vietnam, the U Minh Ha National Park has implemented a sustainable shrimp farming model that incorporates mangrove restoration. According to the World Wildlife Fund (WWF), the project has successfully restored over 1,000 hectares of mangroves and has demonstrated improved water quality and increased biodiversity. Specific data on the environmental success of the project may be available through scientific publications or project reports.
