Types of Sapu-Sapu Fish that Invade Indonesian Waters

YOGYAKARTA - The handling of sapu-sapu fish is currently gaining support from various parties. In Jakarta, the steps to destroy and clean up sapu-sapu fish have been openly encouraged, even to the attention of the Governor of DKI Jakarta. This support shows that the existence of sapu-sapu fish is no longer considered a small problem, but a real threat to the aquatic ecosystem.

When its population is not controlled, these fish can dominate rivers, reservoirs, and waterways, then get rid of local fish that should naturally live in those habitats. Therefore, the public needs to understand what types of sapu sapu fish are found in Indonesia and why their existence needs to be controlled.

Getting to Know the Sapu Sapu Fish

The name mop-mop fish is a general term for a group of fish from the family Loricariidae, especially from the genus Pterygoplichthys. These fish were originally known as aquarium cleaning fish because of their habit of sticking to the surface and eating algae or organic debris. However, when released into the open waters, these fish actually evolved into invasive species.

The ability of the mop-mop fish to survive is very high. It is able to live in murky, polluted waters, even in environments with low oxygen levels. This is the nature that makes the mop-mop fish easy to breed and quickly dominate new areas. In the long term, its population can put a lot of pressure on the balance of the aquatic ecosystem.

Why is the Sapu Sapu Fish Called Invasive?

Invasive species are organisms that enter new habitats, then develop aggressively to disrupt native species. The mop fish falls into this category because it has an incredible adaptability, a large number of eggs, and few natural predators in Indonesian waters.

As their populations increase, these fish can take up living space, food, and resources that should be used by local fish. In addition, pufferfish are also known to have a hard body and natural protection in the form of plates on their bodies, making it more difficult to be preyed upon by predators. This is why controlling pufferfish is becoming increasingly important over time.

Types of Catfish that are Widely Found in Indonesia Pterygoplichthys pardalis

One of the most common types of catfish found in Indonesia is Pterygoplichthys pardalis. This type is known to have a distinctive body and belly pattern, although to the general public it often looks similar to other types.

This species is among the most adaptable in urban rivers and waterways. Because of its ability to survive in poor environmental conditions, P. pardalis is often the most dominant species in waters that have been polluted or have experienced ecosystem disruption.

Pterygoplichthys disjunctivus

The next type is Pterygoplichthys disjunctivus. Visually, this fish is indeed similar to P. pardalis, so it is difficult to distinguish without more careful observation. The difference is usually seen in the body pattern, especially on the abdomen and the pattern of spots.

The presence of P. disjunctivus in Indonesia shows that the invasion of the mop-mop fish is not only from one type. This is important to understand because the more species that enter, the more complex the control efforts.

Hybrid or Mixed Form

In addition to these two main types, in some waters, mop-mop fish with mixed or hybrid characteristics are also found. This means that there are forms that are not completely the same as pure species, but show a combination of the two different types.

The presence of hybrid forms makes field identification more difficult. From the management side, this condition is also a challenge because the invasive fish population is no longer as simple as one type. There is a possibility of a wider spread and higher adaptability.

The Impact of Sapu Sapu Fish on Indonesian Waters

The explosion of the mop fish population has many negative impacts. First, these fish can suppress the native fish population by seizing food sources and living space. Second, the dominance of mop fish can change the structure of the fish community in a water body, so that biodiversity decreases.

In addition, sapu-sapu fish is also often associated with environmental damage in the waters. In some places, its activities are considered potentially aggravating the condition of dikes or river banks. Although not always seen directly by the community, the presence of this fish in very large numbers is clearly a serious threat to the balance of the ecosystem.

Why is there a need for destruction and control?

The destruction or control of the mop-mop fish does not mean it is done without reason. This step is taken to protect the local ecosystem so that native fish still have a chance to survive. If left to continue to develop, mop-mop fish will be increasingly difficult to control and the impact can spread to more areas.

Support from local governments, environmental communities, to the general public is important in this effort. Handling is not enough to be done once, but must be sustainable and accompanied by education so that the community no longer releases aquarium fish into public waters.

In general, the types of catfish that have invaded Indonesian waters consist of Pterygoplichthys pardalis, Pterygoplichthys disjunctivus, and hybrid or mixed forms. All three indicate that the invasion of catfish in Indonesia is quite complex and needs to be handled seriously.

The more people understand the type of sapu sapu fish and its impact, the greater the opportunity to keep rivers, reservoirs, and waterways healthy. Support for the destruction and control of sapu-sapu fish is an important step to protect local fish, maintain the balance of the ecosystem, and prevent damage to wider waters.
