Abstract
Studies of a population of Tetraclita stalactifera from Bahía Ballena, Costa Rica, indicate that, as expected, the Zero year class exhibits the fastest growth rate. For any age, net increments per year are higher here than those observed in northern populations. Growth seems to be very consistent during the year. It slightly declines during the period August through October, just before the release of the nauplii. These and other differences, such as longevity and reproduction, may be influenced by the variation and constancy of the prevailing temperature.
