Planktonic eggs and larvae of marine teleost fishes are considered as ichthyoplankton until they improve active locomotion. These fishes usually produce a large number of propagules however, the great majority of them die before recruitment due to the extrinsic conditions such as predation, starvation and aberrant drift. In this period, small variations in survival rates may cause important differences in recruitment success. On the other hand, the presence of the ideal habitats which can sustain maximal survival for propagules, can significantly change in space and time. Therefore, it is critically important that emergence of propagules should match with the appearance of ideal habitats. To ensure this match, fishes have advanced different spawning strategies. In this review, intrinsic (spawning strategies) and extrinsic (environmental factors) conditions affecting the spatio-temporal distribution of ichthyoplankton have been evaluated on a theoretical basis by discussing match-mismatch dynamics and recruitment hypotheses.
