The tsunami on 26th December, 2004 caused extensive damage to coastal communities and affected many marine ecosystem in southern regions of India and Andaman and Nicobar islands affecting 2,260 km of coastline. The most affected regions were the state of Tamil nadu and the Andaman and Nicobar archipelago. The present research analysis the impact of tsunami on finfish eggs and larvae and its distribution patterns. It deals how the tsunami impinges directly on ichthyoplankton ecology. After the tsunami effect, the eggs and larvae samples were collected and compared with previous year data of the same month (January 2004 and January 2005). We selected five stations, 0.5 1,3,5 and 10 km distance from the shoreline. During the present study a total of 1067 eggs and 285 larvae belonging to 29 families and 57 species were sorted and identified. The pre and post tsunami collection shows the significant variation on eggs and larvae distribution. During pre tsunami and zooplankton biomass was highly correlated with ichtyoplankton density with all the five station significant at 1 % level (p-value <0.01) but there is no correlation observed in the post tsunami samples.
