  ABSTRACT: Sturgeon farming has high potential economic value, but the industry is characterized by late fish maturity, leading to a long payback period for sturgeon farms. Early sex determination (ESD) of fish is important for increasing the profitability of sturgeon farms due to early male separation, thus enabling growing more females and producing more caviar for the same farm area. The data for Russian sturgeons farmed in northern Israel and the results of molecular markers developed for ESD are used in this study. Two sturgeon sex determination technologies are examined and compared from an economic point of view: 1) using molecular DNA markers for ESD at the age of 0.5 years; and 2) using endoscopic methods at the age of 3.5 years, as is currently done in many sturgeon farms. For this purpose, a bio-economic model of a sturgeon farm was developed and an economic evaluation of a sturgeon farm was made to compare both technologies. The ESD technology results in a significant improvement in the economic performance of sturgeon farms. This improvement is greater when caviar prices are lower.
