Justification of terms limitation for brine shrimp cysts harvesting in Crimea
Based on literature data systematization and analysis, potential negative consequences of brine shrimp cysts harvesting in the saline water bodies of Crimean Peninsula (Russia) have been investigated for different seasons. In order to avoid those consequences, it is recommended to make provisions for permission to harvest brine shrimp cysts (both for commercial fishing and angling) from October 1 to February 28 in fishery regulations. This measure should apply both to the inland water bodies of the Crimea and to the water bodies connected to the Sea of Azov. If further observations establish that the abundance of the mature shrimps producing cysts in water bodies in October is reasonably large, it would be rational to shift the starting date of harvesting to mid October or to November 1. In case brine shrimp cyst harvesting is suspended due to implementation of the recommended harvesting volumes within a calendar year, it is considered to be feasible to introduce a ban on their harvesting in January and February as well.
