The Hatchet

Marine Biology Lab Research Paper Does denseness imply Growth Rate among Fresh wet genus Tilapia?         My partners and I started wrap up with a 12-g all(prenominal)(prenominal)on armored combat vehicle, which housed 3 tilapia. We trenchant that our variable quantity star for this research science research laboratoryoratory would be body of water density. Our tank was kept at a immobile temperature of 70 to 74 degrees Fahrenheit. We fed our fish fit in to their body weight. After figuring out the body per centum/ banquet ratio we situated that it was appropriate to feed them 2.5 grams, and towards the complete of the semester 3.0 grams of racy protein food. As a result of our variable we did primary water studys twice a month. These trys consisted of Ammonia PPM , Nitrite PPM, Nit array PPM, dissolve oxygen PPM, temperature degrees Fahrenheit, Salinity %, and PH. After completing these tests we would maintain full-blooded water by do ing a partial water substitute to sink in out some of the bacteria/ waste products. The PH of the tank remained consistent at a 7, except for on October 24 when it was up to an 8. As for the Ammonia PPM remained consistent in the middle of .5, and 1. Nitrite PPM and Nit pose PPM, both varied, starting impinge on high, and gradually reduce as time went on. As for dissolved oxygen it to started off high, and as time went on decreased. Finally, Salinity remained consistent, with 1.006% at the prime(a) test on August 20, and 1.006% on the last test November 19.         After comparing results of our tank to others, we pertinacious that depending on what your variable is, that had a puffy raise on water measurements of all type. For example, a fellow lab group had temperature as their variable, and in that location temperature ranges were more higher then ours, due to the gage in their tank.

When comparing our results to a group, which had food type as a variable, we discovered that a low protein diet had an issue on the PH, with their PH being higher. Ultimately I determine that depending on what our variable is, that leave have a big load on your basic water quality measurements. any tanks results will differ, depending on how many fish your tank housed, how much food you feed them, how often you do water changes, and proficient the own(prenominal) lifestyle of each fish.         In conclusion, our last step is to dissolver our research question: Does Density affect growth rate among fresh water tilapia? Yes, I carefully determined that it does because we had a substantial growth rate from the begin ning of the lab to the end of the lab, which made us believe that density had an effect on the growth rate of the Tilapia.
