Abstract
Strombus gigas, S. costatus, s. pugilis, S. raninus, S. gallus and s. alatus are of commercial importance in the Caribean. Economically, S. gigas is the most important and consenquently the most widely studied. In this overview is analyzed the effects of temperatures on the development of shell growth stages of conch veligers, metamorphosis rate, settlement rate an survival rate. Temperature has long been suggested as an important factor regulating the developmental rate, length of pelagic life, and mortality of larvae from benthic marine invertebrate organisms. It is known that the rate of early cleavage, within certain limits, is related directly to water temperature. The purpose of this paper is to analyze the effects of temperature (24-32°C) on the veliger's development until metamorphosis which is attained within 14 days at 29°C to 60 days at 27°C, Why?.
