The Effect of Pineapples (Ananas comosus) Waste Extract on the Growth Performance of Nile tilapia (Oreochromisniloticus) Fingerlings

In Malaysia, tilapia is the common and important aquaculture species that are produced for the human daily consumptions. The main purpose of this experiment is to determine the effect of pineapples (Ananas comosus) waste (peel and crown) extract on the growth performance of Nile tilapia (Oreochromis niloticus). In this experiment, there are four different types of treatments. The first treatment is control (Diet 1) which is only giving the commercial pellet to Nile tilapia. For the second treatment (Diet 2),
the Nile tilapias were fed with commercial pellet + 10 % pineapples waste extract (PWE). Then, for third treatment (Diet 3), the Nile tilapias were fed with commercial pellet + 20 % pineapples waste extract. Lastly, for the fourth treatment (Diet 4) Nile tilapia were fed with commercial pellet + 30 % Pineapples waste extract. From the result, Diet 4 showed the weight gain 16.90 g, specific growth rate (SGR) with 2.67 %, feed conversion ratio (FCR) was 4.69 and survival rate was 95.55 %. Then, followed by Diet 3 with weight gain 15.15 g, specific growth rate (SGR) was 2.50 %, feed conversion ratio (FCR) was 3.87 and survival rate was 75.66 %. Diet 2 showed the weight gain 14.68 g, specific growth rate (SGR) was 2.46 %, feed conversion ratio (FCR) was 4.88, survival rate was 81.11 % and followed by Diet 1 with weight gain 13.91 g, specific growth rate (SGR) was 2.42 %, feed conversion ratio (FCR) was 3.35 and survival rate was 67.78 %. In conclusion, the tilapia fed the feed supplemented with 30 % PWE were resulted in the optimum weight gain, optimum SGR, and better survival rate for tilapia fingerlings but for FCR, not in the optimum range. Alternative to improve this experiment is made a new formulation of fish feed by added pineapples waste.
