Abstract

Fluctuating asymmetry of bilateral meristic traits is one of the simple methods to calculate phenotype variation and discover the stability of fish development. The aims of this research are analyzing quantitative information about the level of asymmetry of Black Nile Tilapia and Red Nile Tilapia in Kabat Banyuwangi Fish Hatchery Center (BBI) as reference breeding program at Kabat Banyuwangi Fish Hatchery Center. The length of Black Nile Tilapia and Red Nile Tilapia was 50 - 150 gram with 100 samples of fish for each strain so the total is 200 samples of fish. Bilateral meristic traits that have been observed was the number of soft pectoral fins, the number of soft ventral fins, the number of scales on the lateral line, and the first-gill filter of Nile Tilapia. The results show that the highest value of the fluctuating asymmetry of number (FAn) and the fluctuating asymmetry of magnitude (FAm) are 0.65 and 1.38 for Black Nile Tilapia and 0.6 and 1.04 for Red Nile Tilapia. However, the lowest value of FAn and FAm are in soft ventral fins which are 0.22 and 0.22 for Black Nile Tilapia and 0.37 and 0.37 for Red Nile Tilapia.
