| description | Feeding habits of Caspian marine shad Alosa braschnikowii (Borodin, 1904), inhabiting in the western part
of Caspian Sea such as prey spectrum and seasonal dynamics have been studied. As in other parts of Caspian Sea, throughout the year, the main hunt of Caspian marine shad constituted kilkas, gobies and
shrimps while other groups of zoobenthos were represented in a lesser extent. Importance of other fishes
and zoobenthos in the diet of Caspian marine shad is influenced by their ecological morpho-functional
peculiarities. Seasonal changes of species composition and proportions of fodder food items are caused by
life cycles of fishes and migrations of fodder entities. The changes of food composition depending length
of fishes, the depth and haul region are analyzed. Caspian marine shad most intensively feeds in spring
(March – April) before spawning and in summer (July) after spawning. |
