Pectoral Fin Morphometry of Nile Tilapia (Oreochromis niloticus) Cultivated in Different Aerator and Filter

Anomaly of pectoral fin caused by inappropriate amount of oxygen and ammonia within water, which expected to be resolved by the combination usage of aerator and filter. This study aimed to analyze the combination usage of aerator and filter with different amount toward the growth of nile tilapia’s pectoral fin. This study used a 2×2 factorial completely randomized design consisting 4 treatments (ANF, AANF, AF, and AAF) with 6 replications. The measurement variable of pectoral fin including length, width, weight, and ratio of pectoral fin’s length with total size of fish. The measurement analyzed using two way-ANOVA and continued with LSD test. The results of combination usage of aerator and filter revealed a significant effect (P0.05) to the pectoral fin length, pectoral fin width, pectoral fin weight, and ratio of pectoral fin length to total body length. The research’s conclusion was the combination usage aerator and filter had positive impact toward the growth of nile tilapia’s pectoral fin. The study’s novelty is the combination usage of aerator and filter with different number to promote the growth of the cell within the pectoral fin of nile tilapia. This research would benefit people by discovery of the combination usage of aerator and filter to improve the growth of nile tilapia’s pectoral fin.
