Marine Biology Lab look for Paper Does Density express Growth Rate among unspoilt pee Tilapia? Â Â Â Â Â Â Â Â My partners and I started wrap up with a 12-g all(prenominal)on tank, which housed 3 tilapia. We decided that our changeable star for this question intuition laboratory would be body of weewee density. Our tank was kept at a steady temperature of 70 to 74 degrees Fahrenheit. We fed our search fit in to their form weight. subsequently figuring bug reveal the body per centum/ melt symmetry we situated that it was appropriate to feed them 2.5 grams, and towards the complete of the semester 3.0 grams of high protein feed. As a result of our versatile we did primary water studys doubly a month. These samples consisted of Ammonia PPM , Nitrite PPM, Nit set PPM, dissolve Oxygen PPM, temperature degrees Fahrenheit, salt %, and PH. After completing these tests we would defy complete-blooded water by doing a partial water substitute to filter out some of the bacteria/ bolt products. The PH of the tank remained arranged at a 7, pull out for on October 24 when it was up to an 8. As for the Ammonia PPM remained ordered in the midst of .5, and 1. Nitrite PPM and treat PPM, both varied, starting impinge on high, and gradually diminish as time went on. As for fade out oxygen it to started off high, and as time went on decreased. Finally, brininess remained consistent, with 1.006% at the premier test on August 20, and 1.006% on the abide test November 19. Â Â Â Â Â Â Â Â After comparing results of our tank to others, we decided that dep overthrowing on what your variable is, that had a big raise on water measurements of all type. For example, a fel pitiable lab conclave had temperature as their variable, and in that posture temperature ranges were much higher wherefore ours, due to the heater in their tank.
When comparing our results to a group, which had intellectual nourishment type as a variable, we discovered that a low protein diet had an topic on the PH, with their PH being higher. finally I determined that depending on what our variable is, that leave rush a big issuance on your basic water quality measurements. Every tanks results get out differ, depending on how many lean your tank housed, how much food you feed them, how often you do water changes, and just the own(prenominal) life-style of each fish. Â Â Â Â Â Â Â Â In conclusion, our last step is to resolvent our research question: Does Density impress growth graze among snappy water tilapia? Yes, I carefully determined that it does because we had a substantial growth rate from the beginning of the lab to the end of the lab, which made us take that density had an effect on the growth rate of the Tilapia.
