A survey of production Managers in Greek fish farms was used to evaluate their level of job satisfaction and factors affecting it. Production Managers in Greek Fish farms exhibited high level of job satisfaction with more than 44% of them exhibiting job satisfaction levels >70. The majority (77.7%) of the sample had age>30 and 44% of them had postgraduate qualifications. The length of service varied between 6 and 20 years with an average 13.72 years of service. The annual salary ranged between 22K and 38K with an average of 30,670 Euros. The perceived level of participation of the staff in the decision making process of the company was high with values ranging from 3 (a low degree of participation) to 7(high degree of participation). The results indicate that job satisfaction is mostly increased with increasing level of participation in the decision making, wages and age and less by the productivity of the fish farm. Interestingly, the data presented here, indicate a negative effect of the length of stay (Spearman"s correlation= -0.24, P<0.05) on job satisfaction. This is an alarming result, production managers may be experience difficulties in coping with the current difficult economic conditions that Greek fish farms are exposed to as a results of the financial crisis. Under these adverse economic conditions of Greece, several businesses including the fish farms reduced the volume of production, the number of their employees and the wages and bonuses.
