Note
A captive breeding program for three non-restricted Caribbean Strombus conch species: S. raninus, S. alatus, and S. costatus, as well as the commercially threatened S. gigas was established at Harbor Branch Oceanographic Institution in June 2000. A total of 24 adult conch were collected from the Florida Keys: five S. costatus (3 female, 2 male), seven S. raninus (5 females, 2 males), eight S. alatus (4 females, 4 males) and four S. gigas (1 female, 3 males). They were placed in a circular tank (4.5 m dia) that was divided into four equal quadrants (4.1 m²). Egg masses from the breeding tank were measured for size, number of eggs, and egg capsule and strand diameter.
