Fjelldal PG, Madaro A, Hvas M, Stien LH, Oppedal F, Fraser TW Journal of fish biology J. Fish Biol. Skeletal deformities in wild and farmed cleaner fish species used in Atlantic salmon Salmo salar aquaculture. 10.1111/jfb.14337 As a first attempt to assess bone health in cleaner fish production, wild and cultured ballan wrasse Labrus bergylta and lumpfish Cyclopterus lumpus were examined by radiology. In C. lumpus, wild fish (57%) had more vertebra deformities (?1 deformed vertebrae) than cultured fish (2-16%). One wild C. lumpus had lordosis and another was missing the tail fin. In L. bergylta, wild fish (11%) had fewer vertebra deformities than cultured individuals (78-91%). Among the cultured L. bergylta, 17-53% of the fish had severe vertebra deformities (?6 deformed vertebrae) with two predominate sites of location, one between vertebra 4 and 10 (S1) in the trunk, and one between 19 and 26 (S2) in the tail. Fusions dominated S1, while compressions dominated S2. Although wild L. bergylta had a low vertebra deformity level, 83% had calluses and 14% had fractures in haemal/neural spines and/or ribs. The site-specific appearance and pathology of fracture and callus in wild L. bergylta suggests these are induced by chronic mechanical stress, and a possible pathogenesis for fish hyperostosis is presented based on this notion. In conclusion, good bone health was documented in cultured C. lumpus, but cultured L. bergylta suffered poor bone health. How this affects survival, growth, swimming abilities and welfare in cultured wrasse should be further investigated. SIGNIFICANCE STATEMENT: Skeletal deformities were studied in ballan wrasse and lumpfish of both wild and cultured origin for the first time to identify potential welfare issues when deploying them as cleaner fish in salmon sea cages. While cultured lumpfish showed good bone health, cultured wrasse had a high occurrence of vertebra deformities, which is expected to impact lice eating efficiency and animal welfare negatively. These deformities are most likely induced early in development. © 2020 The Authors. Journal of Fish Biology published by John Wiley & Sons Ltd on behalf of The Fisheries Society of the British Isles.

Fish Biol. Interannual fine-scale site fidelity of male ballan wrasse Labrus bergylta revealed by photo-identification and tagging. 1151-1155 10.1111/jfb.14111 The site fidelity of ballan wrasse Labrus bergylta was studied using photo-identification and external tagging. Five male individuals were observed to defend the same small territory composed of a few rocks during several reproductive seasons spanning 2 to 15?years. These results provide one of the strongest indications of long-term very fine-scale site fidelity in marine fishes. © 2019 The Fisheries Society of the British Isles.
