National Marine Aqaculture Initiative Project Summaries for 2007
State: FL
Principal Investigator: Ken Leber, Mote Marine Laboratory
Abstract/Objectives: The goal of this project is to advance aquaculture technology for common snook in order to demonstrate the economical effectiveness of stock enhancement using this highly prized recreational species. The major impediment to large-scale culture of snook is the lack of controlled maturation and spawning technology t produce large numbers of larvae and juvenile snook. Project efforts will include: 1) develop a year round captive spawning protocol; 2) develop induced spawning techniques; 3) provide eggs for ponds trials; and disseminate project results.
State: MA
Principal Investigator:Cliff Goudey, Massachusetts Institute of technology
Abstract/Objectives: The project goal is to demonstrate the feasibility of the Ocean Drifter concept by meeting the following project objectives: 1) Install self-propulsion system on an Ocean Farm Technologies AquaPod™ 3500 cage; 2) Determine the effect of propulsor operation on fish behavior and O 2 levels; and 3) Conduct self-propelled sea trials to determine energy requirements and control strategies.

Principal Investigator: Scott Lindell, Marine Biological Laboratory
Abstract: The goals for the two-year study are: 1) to complete basic laboratory investigations necessary to develop an acoustic conditioning paradigm for black sea bass so that they will respond to feeding on prepared diets in a defined space for possible recapture even when given opportunities to feed on natural forage, 2) to complete field tests to grow acoustically-conditioned BSB released in open waters without confinement, and document growth and recapture rate of BSB, and 3) to develop an understanding of the economics associated with this project and these methods as models of open ocean finfish ranching and stock enhancement.
State: AL
Principal Investigator:Stephen Watts, University of Alabama
Abstract/Objectives: To develop an economically viable and environmentally friendly sea urchin aquaculture farm. Specific objectives include: 1) determine optimum site selection criteria; 2) develop hatchery and demonstrate husbandry technologies; 3) Formulate least cost pelleted diets; 4) develop new raceway facility and demonstrate technology; 5) demonstrate product quality; 6) collect data for economic model; 7) work with appropriate agencies to develop regulations for sea urchin culture; and 8) disseminate information on sea urchin culture and role urchins play in the ecology of the ocean environment.
State: WA
Principal Investigator:Carolyn Friedman, University of Washington
Abstract/Objectives: 1) develop environmentally and economically effective methods to exclude predators and reduce juvenile geoduck mortalities; 2) evaluate effects on wild conspecifics (source of broodstock) and how to reduce and/or mitigate those interactions, if they occur; 3) assess environmental effects of geoduck culture by comparing benthic communities, sedimentation, and water column interactions; and 4) develop recommendations and guidelines for improvements in production efficiency and yield which address the environmental effects of geoduck aquaculture.
State: CA
Principal Investigator:Barbara Block, Stanford University
Abstract/Objectives: The objectives of this grant are to examine the relationship between temperature, metabolism, diet and growth in captive bluefin tuna. Experiments will focus on measuring the metabolic response of a captive population of adolescent tuna to ambient temperatures and diet regimes under controlled swimming conditions. To meet these objectives we propose the following specific aims: 1) M easurement of metabolic rate in Pacific bluefin tuna fed natural and manufactured diets as the fish swim in a swim tunnel respirometer at various temperatures; 2) Measurement of specific dynamic action of bluefin tuna fed natural or manufactured diets by implantation of archival tags in captive fish in the land-based facility as well as in pens; 3) Examine muscle differences between captive bluefin fed different diets to establish gene expression profiles; and 4) Examine biopsies from penned tunas from a farm to identify metabolic and androgen characteristics of muscle to discern correlations with market value.
State: HI
Principal Investigators:Clyde Tamaru, University of Hawaii
Abstract/Objectives: The development of hatchery technologies that result in juvenile pink snapper (opakapaka) output that satisfies its utility as a tool for managing the fishery as well as being used for commercial-scale open ocean culture activities. Specific objective include; 1) determine the food value of several live food organisms (e.g., copepod, rotifer, and protozoa) through feeding trials using opakapaka larvae; 2) visualize how opakapaka larvae feed; 3) define the live food density/larval density ratio and tank conditions that results in optimal growth and survival of opakapaka larvae; 4) determine the appropriate nutritional quality of feeds that optimize larval growth and survival; 5) develop methods of mass cultivation of live food organisms identified as optimal for larval opakapaka growth and survival; 6) demonstrate a cost effective means to vaccinate juvenile opakapaka with a vaccine for Cryptocaryon sp. (marine ich); 7) validate results obtained in the laboratory at pilot-scale facility; and 8) transfer developed technologies.
