【 摘 要 】

Study on the length-weight relationships and conditions factors of three popular fishes consumption has been done in Banda Aceh in October 2017. This study was conducted to stock assessment and condition of fish. The data was collected at Lampulo Fishery Port, Banda Aceh. Data analysis was done using linear allometric Model (LAM). The results of the length-weight relationships showed that all three species of fish experienced negative allometric growth patterns. The highest b value is shown in Sardinella fimbriata with a value of 2.44, followed by Oreochromis niloticus (2.30) and Euthynnus affinis (2.08). The value of Fulton's (K) condition factor indicates that all three fish species have value> 1.6 with a mean of 3.03. Furthermore, the value of relative weight (Wr) condition factor of three types of fish shows a value> 100 with a mean of 100.23. Thus it can be concluded that the values of K and Wr indicate the environmental conditions of the three types of fish in a stable condition.
