Settlement ecology of the sea urchin Loxechinus albus using suspended collectors in Chiloe Island, Chile

In order to understand the settlement ecology of the Chilean sea urchin, Loxechinus albus, PVC collectors were suspended in the water column in eastern coastal waters of Chiloe Island from 1986 to 1988. Three species of juvenile sea urchin, L. albus, Pseudechinus magellanicus, and Arbacia dufresnei,...

Summary:In order to understand the settlement ecology of the Chilean sea urchin, Loxechinus albus, PVC collectors were suspended in the water column in eastern coastal waters of Chiloe Island from 1986 to 1988. Three species of juvenile sea urchin, L. albus, Pseudechinus magellanicus, and Arbacia dufresnei, were collected. These were the same species as echinopluteus larvae observed in plankton samples collected during the same period. Seventy-nine juveniles of L. albus were collected using a collector placed in August and October 1986 in Yaldad. Their size in April 1987 was 1.1-6.5 mm in test diameter. The settlement period estimated from juvenile growth was January. Some collectors sank by the mass attachment of barnacles and washed away by rapid sea-water currents.
