Broodstock Management of Lumpfish

Samuel M Pountney

Lumpfish

• Cyclopterus lumpus, the Lumpfish is a pelagic/semi-demersal fish belonging to

the family Cyclopteridae.

• Widely distributed on both sides of the North Atlantic.
• Traditional fisheries have been for caviar.
• Now used as a cleanerfish in the Salmon industry

The project

Funded by Scottish Aquaculture Innovation Centre (Establishing a sustainable supply and

• ptimal deployment of Lumpsuckers)
• Industrial collaborations: Pharmaq, Otter Ferry Sea Fish, Marine Harvest Scotland,

Scottish Salmon Company, BioMar

• Headed by Dr. Andrew Davie and Prof. Herve Migaud, Institute of Aquaculture
• 1. Broodstock management

2. Larvae rearing and grow out 3. Cage management 4. Health Management

• 1. Reproductive physiology
• 2. Broodstock methodologies
• 3. Genomic tools

“LumpTemp”

Temperature effects on captive Lumpfish broodstock spawning season and gamete quality.

1. To describe the effects of holding temperature during the spawning season

• n captive broodstock spawning season

and gamete quality. 2. To characterise the process of maturation in captive Lumpfish International collaboration with Ingrid Lein at Sunndalsora AS, NOFIMA Experimental aims

Headlines

High temperature rearing resulted in non-viable eggs. Defined thermal limits for viable captive broodstock spawning. Sperm density was reduced in higher temperatures. Creation of an Oocyte Development scale for Lumpfish
