Many fish purchased and consumed by humans are bred and raised in fish farms. The fish on a farm can be infected by parasites called sea lice, which are small crustaceans that feed on a fish's blood and skin, which may injure or even kill the fish. Jansen and colleagues (2012) analyzed sea lice infections on trout and salmon farms. Fish farms provided data on the numbers of sea lice found on their captive fish. The scientists compared the number of sea lice with the "local farmed fish biomass density," which is a measure of population density that accounts for both the number and biomass (or size) of fish on a farm. Other research has also found a relationship between sea lice infestation and mortality. From this figure and information, how does density of fish on a farm affect the number of sea lice per fish? What type of factor is regulating the size of farmed fish populations and population growth? 100 200 300 400 Local farmed fish biomass density (metric tons) 3. 2. Sea lice counts
