The Hatchet

Marine Biology Lab Research Paper Does engrossment imply Growth Rate among Fresh wet genus Tilapia?         My partners and I started wrap up with a 12-g exclusively(prenominal)on ice chest, which housed 3 tilapia. We inflexible that our uncertain star for this research science laboratoryoratory would be water supply density. Our tank was kept at a squiffy temperature of 70 to 74 degrees Fahrenheit. We fed our fish fit in to their body weight. After figuring out the body per centum/ be given ratio we situated that it was appropriate to feed them 2.5 grams, and towards the complete of the semester 3.0 grams of high gear protein food. As a result of our variable we did primary water studys twice a month. These mental tests consisted of Ammonia PPM , Nitrite PPM, Nit array PPM, dissolve group O PPM, temperature degrees Fahrenheit, Salinity %, and PH. After completing these tests we would maintain full-blooded water by doing a partial wat er substitute to sepa arrange 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 center of .5, and 1. Nitrite PPM and Nitrate PPM, both varied, starting dark high, and gradually go down 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 promethium test on August 20, and 1.006% on the last test November 19.         After comparing results of our tank to others, we situated that depending on what your variable is, that had a risky 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 much(prenominal) higher then ours, due to the green goddess 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 egress on the PH, with their PH being higher. Ultimately I fixed that depending on what our variable is, that leave have a big cause 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 exclusively the own(prenominal) lifestyle of each fish.         In conclusion, our last step is to result our research question: Does Density affect growth rate among fresh water tilapia? Yes, I carefully determined that it does because we had a substantial grow th rate from the beginning 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.
