Samuel M Pountney The PhD and Me • BSc (hons) Marine Biology • MSc Aquaculture • 2014-2016 Wintering Marine Assistant, British Antarctic Survey • 2016+ PhD Broodstock Management of Lumpfish 1. To develop a self-sustaining captive breeding program for Lumpfish 2. Manipulate spawning to industry demand 3. Develop egg management techniques

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 optimal 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 1. Reproductive physiology 2. Larvae rearing and grow out 2. Broodstock methodologies 3. Cage management 3. Genomic tools 4. Health Management

“LumpTemp” Temperature effects on captive Lumpfish broodstock spawning season and gamete quality. International collaboration with Ingrid Lein at Sunndalsora AS, Experimental aims NOFIMA 1. To describe the effects of holding temperature during the spawning season on captive broodstock spawning season and gamete quality . 2. To characterise the process of maturation in captive Lumpfish

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