Excessive exploitation of commercial aquatic resources, especially valuable Caspian sturgeons, has exposed these living resources to high extinction risks. This study was undertakenusing field-based surveysacross fishing zones in Golestan province and by designinga questionnaire. Data were collected through the distribution of 172 questionnaires among fishermen communities to answer questions related to social, economic, fisheries and conservation factors which are likely to contribute in the occurrence of illegal fishing. Following the evaluation of validity and reliability of the questionnaire, data were analyzed using logit model. Results indicated that factors such as home distance to the sea, type of fishing vessels, type of catch ownership, time and depth of fishing activity had significant effect in the incidence of illegal fishing. Fishing efforts of illegal fishermen for sturgeon harvest in Golestan province were mostly occurred during night and in shallow depths, and using non-standard fishing equipment. In conclusion, it appears that the probability of the occurrence of illegal fishing is in association with a range of social, economic, fisheries and conservation factors.
