Modelo sintético del desarrollo larvario de <i>Strombus pugilis</i> (Mesogastropoda: Strombidae)

Abstract

The development or Strombus pugilis larvae was studied over a period of 31 days in laboratory culture. Experiments were conducted al 29°C ± 1°C. Veligers were reared at 200 larvae·l-1 in 4 liter containers. Larvae were fed with the microalgae Tetraselmis suecica at l000 cells·l-1. Nineteen development characteristics are described from hatching to settlement. Based on chronological appearance of the characteristics three sets (larval maturation, metamorphic processes and settlement) and seven development stages are proposed.
