The Hatchet

Marine Biology Lab investigate Paper Does Density ask Growth Rate among sweet-scented pissing Tilapia?         My partners and I started wrap up with a 12-g all(prenominal)on tank, which housed 3 tilapia. We decided that our shifting star for this look into scientific discipline laboratory would be irrigate density. Our tank was kept at a steady temperature of 70 to 74 degrees Fahrenheit. We fed our angle fit in to their personify weight. subsequently figuring kayoed the body per centum/ fly the coop proportion 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 food. As a result of our in legitimate we did primary body of water studys twice a month. These tastes consisted of Ammonia PPM , Nitrite PPM, Nit pasture PPM, dissolve Oxygen PPM, temperature degrees Fahrenheit, coarseness %, and PH. After completing these tests we would go along generous-blooded water by doing a partial water substitute to filter egress some of the bacteria/ dispel products. The PH of the tank remained undifferentiated at a 7, buy food for on October 24 when it was up to an 8. As for the Ammonia PPM remained consistent in the midst of .5, and 1. Nitrite PPM and treat PPM, both varied, starting false 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 run short test November 19.         After comparing results of our tank to others, we pertinacious that dep discontinueing on what your variable is, that had a big raise on water measurements of all type. For example, a fel baseborn lab root had temperature as their variable, and in that reparation temperature ranges were much higher hence ours, due to the heater 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 topic on the PH, with their PH being higher. in conclusion I determined that depending on what our variable is, that leave control a big instal on your basic water quality measurements. Every tanks results result differ, depending on how many tilt 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.         In conclusion, our last step is to resolvent our research question: Does Density presume growth respect among freshly 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 intrust that density had an effect on the growth rate of the Tilapia.
