The price of motan fish in the market ranges from around Rp. 20.000-30.000/kg. To understand the morphometric, meristic and growth pattern of this fish, a research was carried out in Tanjung Kudu Lake from September-November 2020. The number of fish caught from the lake was 111 fishes (79-157 mm TL and 3-42 gr BW). There were 26 morphological characteristic measured and 9 meristical characteristic observed. General body from of the fish is not changing as the fish growing. The meristic characteristic of the fish were as follow : D.I.8-10, P.10-7, V.II.7-9, A.4-7.3, C.12-22.8, while the number of scale in the frontal area of the dorsal fin was 10-27, around the body was 20-44, around the base of the tail was 12-27 and in the lateral line was 36-65. The length-weight relationship shown that the growth of male is positive allometricin male (b = 3.6241) and in female (b = 3.6737).Keyword: Thynnichtys thynnoides, Tanjung Kudu Lake, Morphometric, Meristic, positive allometric.
