“…Genetic selection of Atlantic salmon in Norway has resulted in an increase in growth rate of 15–20% per generation (Storebakken 2002). High growth rate is likely to be linked to increased food consumption stemming from selection of individuals that have dominant and aggressive feeding characteristics (Speare 1998).…”

A mechanism for the development of bloat in salmonids is proposed and explained in terms of the physiology of digestion and osmoregulation in fish. Understanding the causal factors for bloat enables control measures to be identified. In farmed salmonids, the chyme produced during the digestion of nutrient-rich pelleted foods that rapidly disintegrate in the stomach will be a potent activator of a negative feedback mechanism (enterogastric control), which slows stomach emptying to protect the small intestine from nutrient overload. In saline environments salmonids continuously drink sea water to replace fluid lost across the gills. Fluid loss is increased during periods of stress caused by factors such as low oxygen levels, elevated temperature or high salinity. When ingestion of nutrient-rich food results in prolonged activation of enterogastric control, slowed stomach emptying leads to decreased absorption of water, thirst and increased drinking. This further exacerbates stomach distention. The proposed mechanism for the development of bloat is supported by on-farm experience where measures to control bloat include reducing food intake, altering the composition of the diet and using appropriate strategies to reduce stress.

“…The proportion of body fat in farmed salmonids correlates with the concentration of fat in the feed (reviewed by Bell 1998; Jobling 2001; Rasmussen 2001), and the composition of the tissue deposited as somatic growth tends to become more fatty as the fish grow larger (Wathne 1995; Storebakken 2002). For example, the proportion of fat in both the fillet and viscera of Atlantic salmon Salmo salar L. has been reported to increase significantly as the concentration of fat in the feed is increased (Einen & Roem 1997; Refstie, Storebakken, Bæverfjord & Roem 2000).…”

Tissue (fillet, viscera and carcass) distributions of fat were examined in Atlantic salmon, Salmo salar L. (≈740→≈1400→≈2000 g) to test the hypothesis that the fillet becomes increasingly important as a fat depot when fish increase in size. The salmon were fed for 11 weeks on either a high‐fat feed (H: ≈39% fat) or a low‐fat feed (L: ≈28% fat), and half of the fish were then subjected to a dietary switch to create four feed treatments (HH, HL, LL and LH). Fillet fat concentration increased with the passage of time, and the fillet also represented an increasing percentage of the body mass (≈48.5→≈55→≈58.5%) as the fish increased in size. As a consequence, the fillet became increasingly important as a fat depot, containing ≈30% of the body fat in the small fish at the start of the experiment, and ≈50% in the fish sampled at the end of the trial. The proportion of fat localised in the viscera was little influenced by either fish size or feeding treatment, and was within the range of 19–25%, whereas the carcass held a decreasing percentage of the body fat stores as fish size increased. There was a highly significant negative correlation between the percentages of body fat found within the carcass (C) and fillet (F): F = 73.589–0.9285C (R2 = 0.973; n = 13). Although the fillet became more important as a fat depot as fish increased in size, the percentage of the body fat reserves found within this tissue appeared to plateau at 50–55%.

“…Feeding frequency mainly depends on species cultured, age, size, feed quality and environmental factors [5,[7][8][9][10][11]. These characters of species and environmental factors influence gastric evacuation time (return of appetite) of cultured organisms and gastric evacuation time of cultured organism on the other hand influences feeding frequency [12].…”
