DEMONSTRATION OF SEAWORM AQUACULTURE IN
MAINE
A Near to Market,
Maine Technology Institute (MTI) Development Award funded project
started in 2003.
PROJECT
SUMMARY
INTRODUCTION
The newly formed
company, Seabait (Maine) LLC is currently developing the first
commercial seaworm aquaculture operation in the USA. Using technology
developed over the last 2 decades in the UK by Seabait Ltd, the company
hopes to adapt the systems and techniques to local sandworms and the
Maine environment by the use of recirculation systems. The market for
sandworms as fishing bait in the USA is well established but now under
supplied due to declining wild catches. There is now also a worldwide
market for frozen sandworms as a high value, pathogen free aquaculture
broodstock feed. Establishment in Maine would be of strategic
importance providing good access to a large existing bait market, and
providing new frozen product for export to Central and South American
shrimp farming.
The company has successfully completed 2 seed MTI grant funded
projects. Work completed during this stage has demonstrated viable
production of juvenile worms using local stocks and will result in the
first production of market size worms in captivity in the USA.
The MTI development award will take the company through a beta test to
commercialization stage by 2005.
Key objectives of this project:
o Design,
construct and develop indoor facilities for growing and harvesting
intensively farmed sandworms in tank-based systems using recirculation
technology.
o The company will test market product for in-depth analysis of the
markets.
PROJECT
DESCRIPTION
P roposed
Technology
Seabait Ltd (UK) is a world pioneer of sustainable mass culture of
marine polychaete worms (seaworms) and this high quality, pathogen free
product is supplied to anglers as bait and to fish farmers as highly
nutritious feed components, reliably year round without the need for
exploiting wild stocks in environmentally sensitive areas.
The newly formed Seabait (Maine) LLC, will utilize unique technology
developed by the parent company for the commercial scale rearing of the
polychaete seaworm Nereis virens and the sale of this product to
fishing bait and aquaculture feeds markets. This partially patented
technology was developed over a 20 yr period in UK using local
broodstocks. Worms are grown on a commercial scale in a sand substrate
using an open, flow through system utilizing waste heat from a local
power station. The project will seek to apply and modify these
techniques to local, Maine seaworms to achieve successful culture in
intensive recirculation conditions.
The technology
includes control of reproduction and time of spawning, artificial
fertilizations, embryo and early larval rearing, first feeding,
juvenile culture, grow-out, harvesting, handling, packaging marketing
and shipping. Most of these will require modification and adaptation to
local broodstocks, local weather patterns, local day lengths and
recirculation. In addition sale of product into the USA will require a
full understanding of local expectations for packaging, delivery
methods, customer preferences and requirements.
Company History and Mission 
Seabait Limited was formed in 1985 to commercialize production of
marine worms based on many years of research. Seabait Ltd benefits from
an IP spin-out agreement with Newcastle University (April 1984 for 25
years) that assigns all IP-relating to commercially important marine
worms to the company and grants access to University facilities and key
personnel.
The leading position
and ‘best practice’ of the company was recognized
by the granting of The Queen’s Award for Environmental
Achievement in 1994, for Sustainable Development in 2003 and for
International Trade in 2003 and the National Training Award in 1995.
There are currently 29 employees of whom 7 are university graduate
level or higher. Two other employees have 15 years of service and a
further 5 have more than 8 years of service with the company having
received full in-house training.
The
company’s strong commitment to continued R&D in order
to scale up and improve prototype processes has resulted in a strong
portfolio of technological achievements protected by patent. Turnover
has increased.
Products
Seabait products contribute to the development of environmentally and
economically sustainable aquaculture. They provide materials for people
to engage in healthy outdoor pastimes without damage to the environment
and aid sustainable production of fish and shellfish promoting human
health. The concept of sustainable economic development is integral to
the companies plans both in the production and consumption of its
products. Seabait (Maine) LLC will contribute to regional economic
growth providing a long-term source of income in areas of economic need
and a basis for sustainable growth.
Seabait
in Maine
Seabait Ltd. established the company Seabait (Maine) LLC to develop and
exploit the technology in the state of Maine. Both companies are fully
committed to both the development and the commercial operations taking
place in Maine and to that end the Seabait Ltd. MD has relocated to
Maine to ensure maximum input by Seabait Ltd. by his full time presence
and commitment. It is envisaged that employees will be Maine residents
and where possible materials and services will be sourced locally by
preference.
Prior
Experience
Seabait Ltd.'s prior experience and research dates back more than
thirty years with the work of Seabait's research director, Prof. Peter
Olive, one of the world's foremost authorities on polychaete
reproduction. As a student of Prof. Olive, the company’s
managing director, began the investigation into the commercial culture
of the sandworm in 1981. Together they started the company Seabait Ltd.
culturing the worms commercially. The company continued to develop the
technology in-house and through postgraduate research at Newcastle
University. Much of this work led to the publication of papers, PhD
theses and patents in both Europe and USA. A great deal of the
R&D undertaken in the UK at a total cost of more than $1.5m
over ten years was assisted by the UK's department of Trade and
Industry.
The most recent and
applicable R&D was carried out in Maine with the assistance of
two MTI Seed Grants (SG747) at the UMaine’s for Center for
Cooperative Aquaculture Research (CCAR) at Franklin. The aim of these
two projects was to identify areas of the technology in most need of
development and to assess the feasibility of such a program. The first
of these projects, SG747 (completed in July 02) established the first
sandworm broodstocks and rearing of juveniles to be carried out in the
USA. It confirmed that as far as reproduction is concerned Nereis
virens in the UK appears to be the same as in Maine.
Broodstocks were
successfully held in recirculation prior to producing by artificial
fertilization 1.35 million eggs yielding 0.94 million weaned
nectochaete larvae. These were reared under recirculation conditions
giving good survival overall. Useful market and distribution
information was also gained during the program (see section 4) During
the second seed grant SG836, completed in October 02, juveniles were
transferred at a variety of grow-out densities under recirculation. The
results proved that growth in recirculation systems was as good or
better than in flow through systems typically used in the UK. Some
product was used for market research and customer feedback to the
product was very favourable.
