The Hatchet

Marine Biology Lab Research Paper Does parsimony imply Growth Rate among Fresh irrigate genus Tilapia?         My partners and I started wrap up with a 12-g entirely(prenominal)on cooler, which housed 3 tilapia. We decided that our multivariate star for this research science science laboratoryoratory would be water density. Our tank was kept at a stabilize temperature of 70 to 74 degrees Fahrenheit. We fed our fish fit in to their body weight. After figuring out the body per centum/ give ratio we situated that it was appropriate to feed them 2.5 grams, and towards the complete of the semester 3.0 grams of last protein food. As a result of our variable we did primary water studys twice a month. These sorts 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 doing a partial water substitute to puree 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 Nitpace PPM, both varied, starting reach high, and gradually flow 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 postmortem examination test on August 20, and 1.006% on the last test November 19.         After comparing results of our tank to others, we impelled that depending on what your variable is, that had a huge 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 ofttimes higher then ours, due to the locoweed 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 progeny on the PH, with their PH being higher. Ultimately I firm that depending on what our variable is, that leave have a big load on your basic water quality measurements. every 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 bonnie 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 beginning of th e lab to the end of the lab, which made us believe that density had an effect on the growth rate of the Tilapia.
