“…Pellets with very high water stability are generally known to affect preference and acceptability by animals with softer pellets usually being preferred to harder pellets (Skoch et al, 1983). In agreement with the findings of this study, diets with lower water stabilities have been reported by some studies to increase feed intake and gastrointestinal evacuation of ingested feed (g DM kg −1 ingested feed) in the target fish species (Adamidou et al, 2009;Aas et al, 2011). Aas et al (2011) observed a 23% increase in feed intake when rainbow trout were fed a diet with relatively lower pellet water stability compared to a G Model diet with higher water stability.…”

Aquac. Rep. (2015), http://dx. a b s t r a c tThe present study investigated the effects of the inclusion of three oilseed by-products (soybean, copra and palm kernel meals) on some physical characteristics of pelletized feeds as well as on voluntary feed intake and faecal matter production by the Nile tilapia, Oreochromis niloticus. The dietary inclusion of soybean meal resulted in a significantly higher feed bulk density relative to the fishmeal control diet. The inclusions of copra and palm kernel meals, however, resulted in lower feed bulk densities. Sinking rates, water stabilities and nutrient retention efficiencies of feed pellets were directly related to feed bulk densities. The soybean meal diet had the fastest sinking velocities, greatest water stability and highest nutrient retention rates. The dietary inclusion of soybean meal, however, significantly impaired feed intake compared to the other three diets. Mean daily feed intakes of the control, palm kernel meal and copra meal diets corresponded to 28.88, 27.01 and 28.31 g during the experimental period and varied significantly from the mean daily intake of the soybean meal diet which corresponded to 20.01 g. Faecal matter production (g dry mass kg −1 ingested feed) was significantly higher in the tilapia groups fed the copra and palm kernel meals. The results obtained from this study show that 30% inclusions of unrefined forms of copra and palm kernel meal in Nile tilapia diets is possible, without adversely affecting feed intake or pellet nutrient losses prior to ingestion.

“…Faster gastrointestinal evacuation rate has previously resulted in reduced nutrient digestibility (Adamidou et al, 2009, Venou et al, 2009. Differences in digestibility between soaked and unsoaked diet were only observed for starch, but not for other nutrients most likely because Atlantic salmon has low capacity to digest starch (Krogdahl et al, 2005).…”

“…Still it remains unclear whether the increased nutrient digestibility observed in the water stable diet was caused by physical feed quality or by lower feed intake. A high feed intake is related to a faster gastrointestinal evacuation rate and is negatively associated with nutrient digestibility (Adamidou et al, 2009, Venou et al, 2009. Gastrointestinal evacuation rate in Atlantic salmon is also affected by coarseness of the ingredients.…”

Effects of dietary moisture content of extruded diets on physical feed quality and nutritional response in Atlantic salmon (Salmo salar)

Feed pellets in modern aquaculture must be of high physical quality to withstand mechanical impacts. However, physical quality of feed has been shown to affect nutritional responses. In the present study, different moisture contents were used to modify physical feed qualities.Effects of dietary moisture content on physical feed quality, feed intake, nutrient digestibility and growth performance in Atlantic salmon were investigated. Different drying times of four commercial-like extruded diets resulted in in dry matter contents of 95.9%, 94.1%, 92.3%, 90.8%. A fifth diet containing 70% dry matter was made

“…All diets fulfil seabream requirements (Lupatsch et al. 1998, 2001) and were formulated to be isoenergetic (19 kJ g −1 ) and isonitrogenous (420 g kg −1 protein), considering also digestibility of diet nutrient have been proved by Adamidou et al. (2009a,b) to be high (92–99%) when tested in European seabass when fish were fed similar diets and similar or equal quantities of the same batch of legumes, respectively.…”

Three legumes [field peas (P), chickpeas (CP) and faba beans (B)] at two inclusion levels [170 g kg)1 (L) and 350 g kg)1 (H)] were evaluated in a 13-week experiment with triplicate groups of 92.6 +/- 5.0 g gilthead seabream (Sparus aurata L.). A control diet included wheat meal, fishmeal (FM) and a mixture of plant ingredients as protein sources. Diets were formulated to be isonitrogenous and isoenergetic and processed in a twin-screw extruder. Restricted feeding was applied (15 g kg)1 of body weight) and growth, haematology and histology parameters were evaluated. Decreased, but not significant, growth values were observed for all diets including legumes compared to the control. Poorer feed conversion ratio values were observed for both P diets and for high level B diet. Liver glycogen increased with increasing starch level, but hepatosomatic index did not differ significantly for any of the diet treatments. Histological examination of internal organs showed no pathological abnormalities that could be related to nutritional treatment. The study indicated that the tested legumes are ingredients that could be used in farmed seabream diets up to 350 g kg)1 without negative effects replacing other carbohydrate sources and part of FM
