Abstract
This chapter addresses the care and maintenance of adult echinoderms that produce gametes and embryos commonly used for molecular, cellular, and developmental biology. Emphasis is on sea urchin and sea star species from North and South America, Europe, and Japan. The chapter discusses adult echinoderm models: (1) reproductive cycles and (2) gametogenesis. Annually, within the gonads of both sexes of most echinoderms, millions of gonial cells (oogonia and spermatogonia) originate by mitosis, produce gonocytes (primary and secondary) that undergo gametogenesis and result in gametes that are stored. The methods for obtaining adult echinoderms are also discussed. Echinoderms are highly sensitive to changes in their environment and are handled very carefully during collection. Echinoderms collected by scuba survive longer than those collected by mechanical dredging. The maintenance of sea urchins in small-scale, closed systems where water is recirculated is described for different species of sea urchins. Two designs for land-based sea urchin aquaculture systems discussed in the chapter are the toboggan and trough systems, along with methods for the care and handling of adult echinoderms.
