Investigation into the relationship between the density of fresh water shrimps in fleet brook and the flow rate of water brook. Introduction Fresh water shrimps (gammarus pulex) are crustacean living in many rivers and streams of this country. They prefer to live in flowing fresh water environments which often has better oxygenated waters that still water environments.2 Aim The aim of my investigation will be to determine the relationship, if any, between the gammarus pulex (fresh water shrimp) population density (the number of shrimps) and the rate of water flow at particular sites of Shir Burn Brook. Preliminary work For my preliminary work, a variety of sampling techniques were carried out to collect samples of freshwater organisms in Shir Burn Brook. The methods include the kick sampling technique and the prodding sampling technique. The range of the flow rate of water in Shir Burn Brook was found to be 0.05m/s-0.25m/s. The samples collected also enabled me...
