Introduction
Lake Titicaca, located on the border between Peru and Bolivia, is one of South America’s natural wonders. Spanning an impressive 8462 square kilometers, Lake Titicaca is one of the largest lakes in the world. Boasting its own biodiversity, the lake is home to a variety of species from birds to llamas. But one of the greatest mysteries remains: Are there any fish in Lake Titicaca?
Background
The Native Inca population have inhabited the region for thousands of years and have long reported the presence of fish in the lake. However, two of the lake’s most notably creatures, the Titicaca Water Frog and the Giant Green Titicaca Lake Rubber Frog, are amphibian species rather than fish. It is presumed that many centuries of hunting by humans has decimated the population of fish living in the lake. Recent research, however, has suggested that there might still be some fish living in the lake.
Fishery Research
In anticipation of the lake forming part of the economic agenda for the future amongst both Peru and Bolivia, fishery research was conducted on Lake Titicaca in 2020. The research involved the use of remote sensing methods to locate any potential fish that may be living in the lake. In addition, the researchers conducted underwater surveys initially in the Bolivian side of the lake and discovered some fish species, including perch and trout.
The Local People’s Opinion
Although the research did not conclusively uncover what types of fish were living in the lake, it provided insight into the views of local people who said that historically there were at least two species of fish, the prietito and the Cochon. However, the population of these fish has diminished over the years, leading to concerns about the sustainability of the fish populations.
Impact of Pollution on Fish Populations
The primary threat to any fish living in Lake Titicaca is pollution. The high concentration of pollutants, heavy metals and damage to habitats has been attributed to the decrease in fish populations. As a result, the authorities in Peru and Bolivia have taken several measures to clean up and protect the lake. This includes monitoring water quality and establishing national parks around the perimeter of the lake.
Retrieving Indigenous Species
In addition to the steps taken to protect the lake, researchers at the Museum of Natural History in La Paz, Bolivia, have been working towards retrieving the indigenous fish species in the lake. This was achieved by introducing more sustainable fishing practices, such as the introduction of fishing limits and the use of eco nets, as well as introducing more sustainable farming practices.
Perspectives From Experts
According to experts, the lake may be teaming with life, but researchers still don’t have a clear understanding of what type of fish actually exist in the lake. Scientists have theorized that the presence of the amphibian species may be a sign that the lake lacks the diversity of fish needed to ensure a healthy population. Scientists are still working to put together a list of the fish species found in Lake Titicaca.
Conclusions?
While Lake Titicaca holds many mysteries, fish still seem to be a prominent part of its ecosystem. The research conducted on the lake confirms the presence of fish in the lake, though it is still unclear as to what species are living, or how many. The authorities on both sides of the lake have taken steps to improve the water quality and retrieve native fish species, and the efforts of the local people and researchers will undoubtedly help to ensure the sustainability of the fish population.
