In an effort to develop suitable culture techniques for sea cucumber (Cucumaria frondosa) in the Northeast, this guide reviews the current knowledge of C. frondosa biology and reports on techniques for the hatchery culture of the Japanese sea cucumber Apostichopus japonicus learned during a research exchange between the United States (NOAA Sea Grant) and South Korea (National Fisheries Research and Development Institute). The final portion of the guide discusses the potential adoption of the culture techniques for A. japonicus for use with C. frondosa
