Settlement

SECORE developed specific substrate tiles for the settlement of coral larvae. Depending on the species, maximum settlement rates of 50-80% and survival rates of 40-90% may be obtained in the first year after settlement.

Working with the SECORE tiles has several advantages for both aquarists and researchers. Tiles can be arranged in grids to work either on small scale for research or on large scale for aquaculture pruposes. Ideally, the specific requirements for settlement of a particular coral species are first investigated on an experimental scale. Once the ideal conditions are known, these can be applied using thousands of tiles for the mass production of sexual recruits.

The produced recruit-tile units can be easily transferred between culture tanks or between different institutions. Last but not least, spacial control of settlement is essential for attaining high survival rates. The micro habitat often determines whether a settler will survive the most fragile early life stages. Depending on the environmental conditions (light!), more than 95% of the larvae may settle in the grooves of the SECORE tiles where they are protected during handling and from predators.
