Fish farms are commonly referred to as Kelong in the local dialect. Most of the villagers in Kukup are fishermen, some go to fishing on the Kukup sea while others set up fish farms near the village.

Since the 1980s, some of the fish farms are open for tourist visitation to experience their daily activities. Hence, tourist can take a boat tour to the fish farms and get a look at how the fish are being raised, it is guaranteed to be eye-opening!

There are many different species of fish kept in the fish farms, some examples include grouper, sea bass, snapper, pomfret, pufferfish, etc. Ultimately, these fish are brought to the local markets and even exported to Singapore to sell.

All the fish are grown from small hatchlings, and different species have different growth rates. For example, it takes a small silver pomfret hatchling about 5 to 6 months to be fully grown. On the other hand, it takes only about 2 to 3 years for a grouper to be large enough for export.

The fishermen need to provide special care of the fish. In other words, it requires 365 days of hard labor to take care of the fish. Moreover, there are also other concerns such as water quality and weather conditions, which can bring a tremendous effect on the fish. During the rainy season, the water quality may be affected. On top of that, environmental pollution further exacerbates the water conditions, ruining the harvest. At the same time, dogs are needed to be kept on the farm to prevent the fish from being stolen.

At the peak of the business, there were over 75 fish farms in Kukup back then. However, there are only about 60 fish farms now. At a glance, the fish farms resemble gigantic floating boxes over the sea, looking extraordinarily spectacular.
