ABSTRACT
Thynnichthys thynnoides is a freshwater fish found in Danau Kebun Nopi.
This fish has economic value and is often caught by fishermen. A study aims to
determine the growth pattern of Thynnichthys thynnoides. The study used a survey
method. Sampling was carried out 4 times from March-April 2022. The results
showed that 107 fish captured consist of 39 females and 68 males. Thynnichthys
thynnoides from the Danau Kebun Nopi has TL 83-165 mm, SL 58-130 mm,
HDL 18-30 and weight 5,61-42,04 gr. The meristic characteristic of the fish were
as follow: D.I.8-10, P.10.4-7, V.1.7-8, A.1.5-7, C.2.16-18, 20-22 pre-dorsal fin
scale, 44-48 around the body scale, 14-20 caudal peduncle scale and 57-60 lateral
line scale. The relationship between length and weight of females showed positive
allometric (b=3,26) and males showed negative allometric (b=2,62). The
condition factors from 0,6854-1,2858 where females were generally in better
condition than the males.
