On the other hand, the Olive Ridley’s figure continuously skyrocketed over the given period. After reaching the peak in 1996 (around 135 units), there was a small fluctuation of this class from 1996 to 2012, finally stood at 130 units in 2012. Noticeably, green turtles showed the least change among the three kinds, even though with a little oscillation over the years and a downward trend.
