- Abstract:
- ... BACKGROUND: Fish telemetry using electronic transmitter or data storage tags has become a common method for studying free-swimming fish both in the wild and in aquaculture. However, fish used in telemetry studies must be handled, anaesthetised and often subjected to surgical procedures to be equipped with tags, processes that will shift the fish from their normal physiological and behavioural stat ...

- Abstract:
- ... The detection of foreign bodies in the food industry has received considerable research attention in recent years. This study aimed to assess the efficacy of combining machine vision with neural network models for detecting residual bones in Atlantic salmon flesh as well as explore the degree to which image quality affects the performance of object detection models. We first employed region segmen ...

- Abstract:
- ... Farmed fish escaping into the wild and other environmental concerns have curbed the expansion of the Norwegian aquaculture industry. Detailed knowledge of both direct and underlying causes of previous escape episodes is crucial to ensure successful development of new technology and targeted safety-measures at fish farms. This paper provides detailed descriptions of both technological, human and or ...

- Abstract:
- ... Salmon lice, Lepeophtheirus salmonis (Krøyer, 1837), are ectoparasites of the Atlantic salmon, their presence on the fish host is often linked to increased economic losses to the aquaculture industry in the northern hemisphere. Initial attempts to control parasite numbers primarily involved chemical treatment methods, however, there has been a gradual shift towards what are considered more environ ...

Interest in land-based farms using recirculating aquaculture systems (RAS) for market-size Atlantic salmon (Salmo salar) continues to grow, and several commercial facilities are already rearing fish. Performance data for commercially available mixed-sex, all-female, and triploid all-female Atlantic salmon reared to market-size in freshwater land-based facilities, however, are limited, particularly ...

To investigate the possible family influence on sea lice grazing of lumpfish on Atlantic salmon, ten families of lumpfish (N = 480) with a mean (± SD) weight of 54.8 ± 9.2 g were distributed among ten sea cages (5 × 5 × 5 m) each stocked with 400 Atlantic salmon with a mean (± SD) weight of 621.4 ± 9.2 g. All the ten cages were stocked with 48 lumpfish (12% stocking density). The stocking of cages ...

The ectoparasitic salmon louse (Lepeophtheirus salmonis, Krøyer 1836) remains a major disease problem and cost driver in commercial Atlantic salmon (Salmo salar L) farming and is also implicated in the decline of wild salmon stocks. The parasite feeds on mucus and blood causing skin damage on its host (i.e. leads to reduced welfare and disease resistance). Underwater lights (UL) are being used reg ...
