A new type of fish food has become available for salmon raised on fish farms. Your task is to design an experiment to compare the weight gain of salmon raised over a six-month period on the new and the old type of food. The salmon you will use for this experiment have already been randomly placed in eight large tanks in a room that has a considerable temperature gradient. Specifically, tanks on the north side of the room tend to be much colder than those on the south side. Describe a design for this experiment that takes account of temperature gradient.

Analyzing results Researchers discovered that the fish subjected to higher temperatures were unable to acclimate, as evidenced by their increased stress and preference to seek out an optimal temperature rather than remain in a warmer-than-normal temperature of water. Making a prediction Making an observation Forming a testable hypothesis Researchers believe the fish could not maintain their optimal metabolic and energy functions in warmer waters so they would have to move. Designing an experiment Researchers documented some species of tropical stenothermal fish moving poleward, away from ocean warming areas. Formulating a conclusion Researchers believed that the blue-green damselfish would move to waters within their optimal temperature range rather than acclimate to the warm temperatures. Researchers devised a way to apply heat stress to the blue-green damselfish in controlled laboratory conditions. Stenothermal fishes exposed to the higher temperatures predicted with climate change will experience

The average metabolic rate (O2 consumption in L/kg x h) for a group of cool-climate fish (held at 10°C for 3 weeks) is compared to that of a second group that is held in warmer water (28°C) for the same length of time. The data is shown in the table below: Acclimation Temperature | Test Temperature | Metabolic Rate 10° | 5° | 1.2 10° | 10 | 2.2 10° | 20 | 3.1 10° | 30 | 4.7 28° | 5 | --- 28° | 10 | 1.5 28° | 20 | 1.6 28° | 30 | 2.3 A) Calculate the Q10 for the oxygen consumption in the mid-range (10-20°C) of animals held at 10°C and 28°C. Which group of fish is more sensitive to temperature change? B) Do the animals held at 28°C exhibit partial, complete, or no acclimation?
