ABSTRACT
The purpose of this paper was to discuss the factors influencing fish demand in Lampung Province. Data were collected by observing fishing fields in the subject area. This study was carried out to examine the correlation between demand and fish nutrition, which is more complicated than other sources of protein. Hence, it explains the reason for the lack of nutrition in Lampung Province. Researchers used three stages of estimation in examining the model, which was called the Quadratic Almost Ideal Demand System (QUAIDS). At the first stage of estimation, the results showed that the model used was relatively good. The coefficient estimated value of food expenditure was positive, and it had a significant effect on its coefficient determination at 96.8%. Next, the research showed a negative factor value for the fish consumption model, indicating that the lower the price, the higher the demand, and vice versa, positioning at 90.5%. Last, the model showed that the variables of price, income, and expenditure did not affect the total demand, but the number of household members had a significant influence on it.
