This paper provides an overview of all the data available on qualitative composition and distribution of ichthyoplankton in the area of the Boka Kotorska Bay. Although the research activities were not conducted continuously, the results showed a high level of diversity and abundance of certain species and proved that the Boka Kotorska Bay is one of the most important spawning areas and feeding grounds for juveniles of a number of pelagic fish species. Analysis of the plankton material resulted in identification of spawning of 40 different species from 7 genera and 20 families. Ichthyoplankton communities’ diversity was analysed by two diversity indices: Shannon’s diversity index (H′) and Simpson’s index (D). Early developmental stages of fish are one of the most sensitive phases in the fish lifecycle, so ichthyoplankton research is one of the main tasks of fisheries biology.
