<![CDATA[The Cikaso River is a lotic aquatic ecosystem in the southeastern Sukabumi Regency, West Java. As one of the major rivers, Cikaso boasts a relatively high fish biodiversity. One species of fish found in the Cikaso River is the Greenback gauvina (Bunaka gyrinoides). Greenback gauvina, or what the local community calls Bobosoh, is widely used for consumption in adult and the juvenile stadiums. Until now, research on the bobosoh fish in the Cikaso River has been limited to discussions of abundance, migration patterns, and its existence in relation to aquatic environment parameters. The study of fish biology parameters, especially regarding the growth of bobosoh fish in the Cikaso River, is not widely known. This study uncovered growth parameters related to the length-weight relationship, growth pattern, and condition factors of the bobosoh fish in the Cikaso River. Fish sampling was executed for one full year from January to December 2021. A total of 539 bobosoh fish with a total length range of 86-236 mm were collected during the study with the help of traps fishing gear. Data analysis of the total length and weight of bobosoh fish reveals a relationship pattern that follows the function W = 0.0014 L2.0895, with a correlation coefficient of 0.96. Based on this function, it is known that bobosoh fish in the Cikaso River exhibit a negative allometric growth pattern (B < 3), i.e., the length tends to be more dominant than its weight growth. The value of bobosoh fish conditions during the study ranged from 0.88 to 1.37. The highest condition factor value in the transition season from the rainy season to the dry season in April is low at the end of the dry season in August.]]>
