It can be seen with high population of this animal. the biggest problems associated with this species are: reduction in fish through de-oxygenation of the water (destroys nurseries), physical interference with fishing and transportation, impediment to urban and rural water supply as well as hydro-power stations, creates habitats for other damaging species such as snails, mosquitoes, and snakes. [12] The lake has a shoreline of 7,142km (4,438mi) when digitized at the 1:25,000 level,[13] with islands constituting 3.7% of this length. A lot of settlements are situated around the shores of Lake Victoria and count on the waters for daily life. [22][39], Most of these lakes are relatively shallow (like Victoria) and part of the present-day upper Nile basin. This is also why so many of the tropical fish that you see in aquariums are cichlids.

It is so big that it is one of the only two water bodies in East Africa where you can see the sunset beyond the water body.

The release of large amounts of untreated wastewater (sewage) and agricultural and industrial runoff directly into Lake Victoria over the past 30 years has greatly increased the nutrient levels of nitrogen and phosphorus in the lake "triggering massive growth of exotic water hyacinth, which colonised the lake in the late 1990s". [41], Other factors which may have contributed to the decline of the water hyacinth in Lake Victoria include varying weather patterns, such as El Nio during the last few months of 1997 and first six months of 1998 bringing with it higher levels of water in the lake and thus dislodging the plants.
