| 總結: | Tilapia breeding program recently carried out to improve seed quality both phenotype and genotype. Cross-breeding between Jantiâ��s Black Tilapia (female parent) and Jantiâ��s White Tilapia (male parent) has been performed by Institution of Germination and Freshwater Fish Farming which is located at Janti Village â�� District of Klaten and produced Tilapia Larasati (Red Tilapia Strain Janti). This study aimed to compare the Tilapia Larasati fifth generation (F5) and it parents based on morphometric and meristic characters, and to know the length-weight relationship of three strains of tilapia. Analysis of morphometric characters performed by Principal Component Analysis (PCA) while the meristic character analyzed descriptively by reviewing the literature. Kinship of three strains were tested by cluster analysis while length-weight relationship analysis was conducted to determine the pattern of fish growth and condition factor. The scatter plot results of the 12 morphometric characters showed that Tilapia Larasati F5 has a similar body form with Jantiâ��s Black Tilapia and has a slightly different form of Jantiâ��s White Tilapia especially in the part of head. Tilapia Larasati F5 and Jantiâ��s Black Tilapia obtained on a longer body, longer forehead, longer jaw (big mouth), and long face and long nose. It result supported by cluster analysis which showed that Tilapia Larasati F5 has a closer kinship distance to Jantiâ��s Black Tilapia viewed from morphometric characters. Analysis of meristic characters showed that the number of scales on the dorsal fin in front of the Tilapia Larasati F5 and Jantiâ��s Black Tilapia amounted to more than the Jantiâ��s White Tilapia. Third tilapia strains had isometric growth pattern. Analysis of the value of condition factor indicates that Tilapia Larasati F5 has the best body condition. |
