U.S. Development of red sea cucumber (Parastichopus californicus) poly-aquaculture for nutrient uptake and seafood export We haven t done much yet... Andy Suhrbier and Dan Cheney, Pacific Shellfish Institute Funded by 2014/2015 NOAA s Saltonstall Kennedy Program (SK) WAS Aquaculture 2016 Las Vegas
Giant California Red Sea Cucumber (Parastichopus californicus) Similar traits as the prized Japanese Sea Cucumber (Apostichopus japonicus) Distributed from Southern California to Gulf of Alaska Declining fisheries in U.S. (Central Puget Sound closed in 2014) Increased demand for product in Asia
Wild and Aquaculture landings of Sea Cucumber
Red Sea Cucumber (Parastichopus californicus) Aquaculture starting in other countries for similar species China, Canada, Russia, Korea, Indonesia and Madagascar, Vietnam and Saudi Arabia Feeds on decaying organic matter, bacteria and benthic diatoms Perfect for Polyculture It feeds on bivalve and finfish waste High absorption efficiency under raft culture
Objectives & Project Partners 1. Examine the genetic population structure of spatially distinct aggregations of the sea cucumber Parastichopus californicus. Lorenz Hauser and Brent Vadopalas -UW and Henry Carson - WDFW 2. Develop hatchery and nursery technology in Manchester, Washington and Seward, Alaska. Ryan Crim PSRF, Paul Williams - Suquamish Tribe, Jeff Hetrick Alutiiq Pride and Ralph Elston - Aquatechnics 3. Estimate mortality, initial growth, and target densities of sea cucumbers in co-culture with farmed mussels, salmonids or sablefish in Alaska (Ketchikan ) and Washington (Totten Inlet and Rich Passage). Vassili Kalashnikov & Andy Suhrbier - PSI w/ Taylor Shellfish and NOAA Manchester. Kate Sullivan & Charlotte Regula Whitefield - SARDFA and Alutiiq Pride 4. Quantify sedimentation and water chemistry characteristics prior and during sea cucumber introduction (Dissolved oxygen, ph, carbon chemistry, nutrients, sedimentation rates and size) in Washington (Totten Inlet and Rich Passage). PSI 5. Advance federal, state and local permitting processes for sea cucumber aquaculture in Washington and Alaska. PSI

Task 1: Examination of the genetic population structure of spatially distinct Parastichopus californicus aggregations. Genetic differentiation at two spatial scales, State differences Geographical regions in WA with concurrent AK and BC studies Detect molecular evidence for adaptive genetic differentiation and Identify markers for routine screening of wild populations and captive broodstock Genetic tissue collected by: Alaska: Stewart Grant of ADF&G Washington: WDFW Dive Team Oregon: Steve Rumrill @ ODFW California: CDFW, dive harvester

Task 2: Develop hatchery and nursery technology in WA and AK Broadcast spawners (May July) Free swimmers for 14-136 days, average 35-52 days. Disease screen prior to outplant Puget Sound Restoration Fund Hatchery Kenneth K. Chew Center for Shellfish Research and Restoration (KKCCSRR) Manchester, WA Native oysters and macroalgae Alutiiq Pride Shellfish Hatchery Seward, AK 6 years experience 10,000 produced (2013-2014) Developing tagging technology

Task 3: Estimate mortality, initial growth, and target densities of sea cucumbers in Alaska (Ketchikan ) and Washington (Totten Inlet and Rich Passage). Growth, mortality, and dispersal monitored 1,000 per site Additional animals for density trials WA using wild juveniles Intertidal and subtidal via Vassili Kalashnikov (dive harvester) Under mussel and sablefish farms Wire mesh cages hanging and on bottom Free range on bottom AK using hatchery produced juveniles Alutiiq Pride Under floating aquaculture (mindful of predators) Wire mesh cages on bottom outplant Free range on bottom
