Abstract

While there is a growing need to increase farm fish production to meet food security needs of a growing population, humane slaughter treatments are not well understood. Use of sedative agents prior to slaughter can facilitate a more rapid and humane slaughter process. The present study was...

Abstract

Continuous data on the condition of fish is necessary to monitor, control and document biological processes in fish farms in real-time, yet acquiring it from a large net-pen environment is challenging. Tools to rapidly detect change in the entire net-pen population are lacking. Automated passive...

Abstract

Fish transportation is an important process during offshore fish farming. Plasma cortisol, glucose, hepatic and muscular glycogen, hematological parameters (white blood cell [WBC], red blood cell [RBC], hemoglobin [Hb] hematocrit [Hct]), hepatic anti-oxidant (superoxide dismutase [SOD], catalase...

Abstract

In farmed animals, individualities have demonstrated links to health and welfare. However, differential modulation of orexigenic, anorexigenic neuroendocrine and endocrine factors in different individuals with different individualities remain unclear. Therefore, we investigated the contribution of...

Abstract

Aquaculture, as one of the largest food production sectors, is a candidate industry to solve the worldwide food shortage. Nitrogenous compounds from uneaten feed and excretion continually destroy the rearing water quality during the breeding which causes slow growth, production reduction, and even...

Abstract

Lice shielding skirts are a preventative measure against salmon lice in Atlantic salmon farming. The skirt is wrapped around the top meters of the net cage to divert the current flow around the cage, and thereby keep the salmon lice out. Despite these skirts being used actively in Norwegian ...

Abstract

Feeding regime, which involve selection of appropriate diet and application of feed itself is a decisive factor in intensive, RAS-based production system - more so, for carnivorous fish culture. It is critical for the economics, resource (feed/nutrients) use efficiency and final profit yield. The...

Abstract

Early maturation of Atlantic salmon male postsmolts is undesirable in aquaculture due to its negative impact on growth, welfare and seawater adaptation, however it is an increasing problem under intensive rearing conditions. The effect of temperature and feeding ration on sexual maturation during...

Abstract

Dissolved oxygen (DO) saturation in the water is a crucial factor in fish performance and welfare. Exposure to low DO can affect a wide variety of functions such as metabolic rate and physiological adaptations including hematological, hormonal, biochemical and osmoregulatory alterations in blood...

Abstract

Thermal delousing has become the most applied method for treatment against salmon lice. However, the temperature range used is strongly aversive for salmonids, and the method is associated with increased mortality. Treatment temperature × duration combinations should be tailored to maximise...
