Guppies In Fish Lab Report

Biologists have done many studies concerning guppies. Guppies are one of the world's most widely distributed tropical fishes, and one of the most popular freshwater fish species. These fishes tend to live in tropical lakes and rivers. In addition, Guppies have a wide color variation. This led Biologists to wonder what was caused the wide coloration of Guppies. Biologists collected data about different types of guppies and where they lived. After observing and collecting data about the guppies, they found patterns within the guppies habitat and if the fishes there were either bright or drab. If the location of the pool is further upstream and the turbidity of the water is low then the variation of guppies will be greater because predators tend to live in habitats where the water is shallow and the turbidity is high. …show more content…
According to the data table provided by the research done by biologists, the turbidity in pool 1 was between 27.50 and 36.25 also the water in pool 1 was shallow. In pool 4 the turbidity was between 3.00 and 8.75, also the pools’ location was further upstream. The data table explains that the higher the turbidity is then the less bright males there will be. In pool 1 there was 28 predators and there was 5 bright males. Bright males tend to not live in more turbid water because it is hard to hide their bright colors against the cloudy water, which makes it easier for predators to find them. But in pool 4 there was no predatory fish and there was 108 bright males. Since there is no predators it allowed for the gene pool of guppies to grow and more variation to
