Sustainability Status Analysis and Strategic Development of Whiteleg Shrimp (Litopenaeus vannamei) Farming through Environmental and RAPFISH Assessment
This study evaluates the environmental impact and sustainability status of whiteleg shrimp farming in Gerokgak, Bali, using RAPFISH and SWOT-QSPM analyses to recommend priority strategies such as biofilter utilization and feed additives for achieving ecological and economic sustainability.

Imagine the ocean as a giant, bustling kitchen where nature cooks up life. In this kitchen, shrimp farmers are like chefs trying to bake the perfect batch of whiteleg shrimp, a type of seafood that has become a global favorite. But just like any kitchen, if you leave too much food on the floor or dump dirty water in the sink, the whole place gets messy, the ingredients spoil, and the chefs get sick. This is the world of aquaculture: a delicate balance between making money and keeping the environment healthy. Scientists use special tools to check if a farm is doing a good job. One tool is like a report card called RAPFISH, which grades farms on four subjects: how they treat the environment, how much money they make, how they treat their workers, and how good their technology is. Another tool is SWOT, which is like a strategic game board where players look at their own strengths and weaknesses against outside opportunities and threats to decide their next move. Finally, there's QSPM, a calculator that helps pick the single best move from a list of options. Why does this matter? Because if we don't figure out how to farm shrimp without ruining the ocean, we might end up with empty plates and a polluted sea.
Now, let's dive into the story of a specific group of shrimp chefs in Gerokgak, Bali, Indonesia. A team of researchers decided to investigate these farms to see if they were sustainable or if they were heading for a disaster. They didn't just guess; they went out, measured the water, counted the trees, and talked to the farmers.
First, they looked at the neighborhood's "green lungs": the mangrove forests. Think of mangroves as the ocean's natural air filters and shock absorbers. The researchers found that while the density of these trees had dropped a bit over the last few years due to land being cleared for other uses, the ecosystem was still holding its own. They measured the water quality and calculated something called a "pollution index." It turned out that the pollution was actually quite low. The ocean and the mangroves were so good at cleaning up the waste from the shrimp farms that the farms weren't overwhelming the system. In fact, the farms were producing waste at a rate that the environment could comfortably handle, like a sink that drains just as fast as the water comes in.
Next, the team gave the farms their "report card" using the RAPFISH method. The results were a mix of highs and lows. The Technology score was the star of the show, earning a "Sustainable" rating of 90.61%. The farmers were using great equipment, monitoring water quality like hawk-eyed scientists, and feeding their shrimp efficiently. The Social score was also strong, landing in the "Potential" range at 73.28%, meaning the workers were generally well-treated and the community was stable. The Environmental score was also in the "Potential" range at 63.19%, showing that while the nature around the farms was healthy, it needed a little extra care to stay that way.
However, the Economy score was the troublemaker. It landed in the "Low Sustainability" zone at just 35.23%. The researchers found that the farmers were struggling with money. They had trouble getting enough capital to start up, their workers weren't always trained enough, and the supply chain was a mess. A big issue was that they relied too heavily on selling their shrimp to the United States. When the US market got shaky or prices dropped, the farmers in Gerokgak took a hit, and they didn't have enough local demand to make up the difference.
So, what's the plan? The researchers used the SWOT and QSPM tools to figure out the best strategy. They decided the farms shouldn't try to expand wildly right now; instead, they should "Hold and Maintain." Think of this as tightening your shoelaces before you run a marathon. The top three strategies they picked to fix the problems were:
- Using Biofilters (Score: 35.886): This is like installing a super-fancy water filter in the kitchen sink to catch all the gunk before it goes down the drain, preventing diseases from spreading.
- Better Feed Additives (Score: 35.528): This involves mixing special probiotics and nutrients into the shrimp food to make the shrimp stronger and grow faster, kind of like giving them a vitamin boost.
- Strengthening Shrimp Clubs (Score: 33.135): This means getting all the farmers to meet up and share their secrets and problems, so they can learn from each other instead of struggling alone.
The researchers suggest a three-step timeline to make this happen. In the first three years, they should focus on fixing the technology and water quality. In the next three years, they need to fix the money problems and restore the mangrove forests. Finally, in the last three years, they should work on selling more shrimp locally and making sure the community is strong enough to keep the farms running for the long haul. The paper concludes that while the Gerokgak shrimp farms are currently in a "potential" state—meaning they have a good foundation but need work—they can definitely become a model for sustainable farming if they follow this roadmap.
