Parasitic sea-lice are the biggest threat facing sustainable salmon production in the world with an annual cost to industry of £500 mill. Using lumpfish as cleaner fish offers an attractive alternative to the use of chemicals or medicines. Research on lumpfish at the Centre for Sustainable Aquatic Research (CSAR) - Swansea University, started in 2014. Following this, an R&D collaboration project was developed with with MOWI (previously Marine Harvest Scotland) (c.£1.2 M) to develop this novel species as a solution to the sea-lice problem facing the industry. With a developing network throughout the North Atlantic, a new four year WEFO project (SMARTAQUA, c £1.2M), and three new UK research and development collaborations started in 2018 (c £1.4M), CSAR are playing an increasingly major role in Lumpfish research and industry development at both a UK and international level.
The lumpfish project continues to provide ample opportunities for enhancing the student experience and to date we have had: three funded postgraduate scholarships (2 PhD, 2 MRes), over 20 UG and PGR student projects have been developed, 3 ERASMUS exchange programs, 6 intern placements and over 70 undergrad students have worked for up to 6 weeks in CSAR learning aspects of lumpfish husbandry and writing a practical report on nutrition and welfare.
A multi-country collaboration with the largest UK cleaner fish supplier (Cleaner Fish Company Ltd.), largest lumpfish producer in the UK (Ocean Matters Ltd), the largest producer of Scottish sourced lumpfish in the UK (Three-sixty Aquaculture) and one of the largest salmon producers (The Scottish Salmon Company), allowed CSAR to develop novel UK disease screened lumpfish for the salmon industry.
As lumpfish are a new species to aquaculture, there is a significant lack of standardisation when it comes to husbandry practices. Sourcing protocols can be difficult and many are shared between facilities. Below are the individual Standard Operating Procedures developed at CSAR for working with lumpfish. All SOPs can also be downloaded.
1. Sampling for pathogen screening in the lumpfish (Cyclopterus lumpus)
This SOP guides the user on the best practice methods for pre-screeninig male lumpfish and the post-screening of female lumpfish
2. Lumpfish larvae transport
This SOP provides the guidelines for the safe transport of lumpfish larvae within bags and insulated boxes.
3. Reception and Traceability of Lumpfish Broodstock
This SOP guides the user on the best practice methods for receiving lumpfish into a quarantine facility and ensuring traceability broodstock during the season.
4. Lumpfish Milt Extraction and Storage
This SOP guides the user on the best practice methods for extracting and storing lumpfish milt.
5. Lumpfish stripping and egg fertilisation
This SOP guides the user on selecting broodstock, harvesting eggs and milt, and best practices for the successful fertilization of eggs.
6. Treatment of Lumpfish Eggs with Buffodine®
This SOP guides the user on the best practice methods treating lumpfish eggs with Buffodine® and transferring them into RAS B.
7. PIT Tagging of Lumpfish
This SOP guides the user on the best practice methods for PIT tagging lumpfish.
8. Lumpfish Vaccination
This SOP guides the user on the best practice method for vaccinating lumpfish.
9. Lumpfish weaning
This SOP describes the protocol used in CSAR for lumpfish weaning which is more prolonged than other examples from industry but it can decrease mortality over the weaning period.
