“…In our study, the highest Ca level is 1.59% far below 3.1%, which might affect trail result. Blood parameters are considered as convincible indicators for the physiological conditions and health status of fish in response to dietary supplements (Congleton & Wagner, 2006;Kader et al, 2010). In our study, dietary Ca supplementation had no significant effects on RBC counts, HGB counts and HCT, which indicated dietary Ca supplementation did not affect the capacity of carrying oxygen and collecting carbon dioxide.…”

“…However, dietary Ca supplementation in diet have no impact on whole body composition, such as fingerling scorpion fish (Hossain & Furuichi, 2000c), juvenile jade perch (Scortum barcoo) (Song, Mao, Wang, Zhu, & Han, 2009), Atlantic cod (Gadus morhua) (Kousoulaki, Fjelldal, Aksnes, & Albrektsen, 2010). Dietary supplements with an excess of Ca relative to P has an adverse impact on the growth and survival of fish, which is related to blood parameters and plasma biochemical parameters considered as convincible indicators for the physiological conditions and health status of fish in response to dietary supplements (Congleton & Wagner, 2006;Kader, Koshio, Ishikawa, Yokoyama & Bulbul, 2010;Kavitha, Ramesh, Kumaran, & Lakshmi, 2012;Davis, 2004). So there is necessary to investigate these parameters relates to growth and health status.…”

An eight weeks feeding experiment was conducted to investigate the effects of dietary calcium (Ca) levels on growth performance, blood biochemistry and whole body composition in bighead carp (105.52 ±0.33g; 16.91±0.09cm). Six practical diets (31.0% crude protein, 6.0% crude lipid) were formulated to contain graded Ca levels ranging from 0.41% to 1.59% of dry diet. At the end of the feeding trial, results showed that survival rate (SR) was not significantly affected by dietary Ca level. Final weight (FW), weight gain (WG), specific growth rate (SGR) increased with the increasing dietary Ca level up to 1.26%, and thereafter showed a decreasing trend, while feed conversion ratio (FCR) showed a converse trend. Furthermore, high Ca level (1.59%) significantly increased the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and significantly decreased serum phosphorus (P) content (P<0.05). Alkaline phosphates (ALP) activity was significantly higher than other groups with Ca-deficient diets (0.41%) (P<0.05). High Ca level (1.59%) significantly decreased serum P levels. Serum Ca levels were not significantly affected by dietary Ca levels (P>0.05). Based on FCR and SGR, the optimal dietary Ca level was determined to be 1.26%, and the corresponding Ca/ P ratio was calculated to be 1.13:1.

Taurine supplementation in diet for olive flounder at low water temperature

The objective of this study was to examine the effect of dietary supplementation of taurine for juvenile olive flounder (Paralichthys olivaceus) at low water temperature (16.4 ± 0.36°C). Fish meal (FM)-based diet was used as the control diet. Four other experimental diets were prepared by adding taurine to FM-based diet at 0.25, 0.50, 1.00, and 1. 50% (T1, T2, T3, and T4, respectively). Each experimental diet was fed to triplicate groups of fish (initial mean body weight, 19.5 g) for 10 weeks. At the end of the feeding trial, growth performance and feed utilization, hematological parameters, non-specific immune responses, whole-body proximate composition, and liver mRNA expression of insulin-like growth factor-1 (IGF-1) were investigated. Feed conversion ratio was significantly reduced while protein efficiency ratio was significantly increased in taurine-supplemented groups. Hematocrit and hemoglobin were also significantly increased while plasma cholesterol levels were decreased in taurine-supplemented groups than those in the control group. Nitroblue-tetrazolium, myeloperoxidase and lysozyme activities, and plasma immunoglobulin level were significantly increased by taurine supplementation. These results suggest that dietary taurine supplementation is effective in improving growth performances, feed utilization, and innate immunity of olive flounder in low water temperature season.

“…Meanwhile, the water-soluble components in the feed, with specific smell and taste, act as chemical stimulants to determine the palatability in a high degree (Xue et al, 2003). The olfactory and the taste bud of fish are sensitive to water-soluble molecules that are most of the available feeding stimulants for fish, including free amino acids, small peptides, and nucleotides (Gao and Li, 2004;Kousoulaki et al, 2009;Kader et al, 2010). These water-soluble nitrogen-components are more abundant in fishmeal than in plant protein sources (Aksnes, 2005).…”

Poor palatability is a limiting factor for replacing fishmeal with other protein sources in aquaculture. The water-soluble molecules with low molecular weights are the major determinants of the palatability of diets. The present study was conducted to investigate the palatability of water-soluble extracts from single protein source (single extract pellets) and the mixture of these extracts with different proportions (blended extract pellets) in juvenile turbot (Scophthalmus maximus). Then according to the palatability of blended extract pellets, an optimal mixture proportion was selected, and a new protein source made from raw protein materials with the selected proportion was formulated to replace fishmeal. Summarily, the palatability of single extract pellets for turbot was descendent from fishmeal to pet-food grade poultry by-product meal, wheat gluten meal, soybean meal, peanut meal, meat and bone meal, and corn gluten meal. Subsequently, according to the palatability of single extract pellets, 52 kinds of blended extract pellets were designed to test their palatability. The results showed that the pellets presented remarkably different palatability, and the optimal one was diet 52 (wheat gluten meal: pet-food grade poultry by-product meal: meat and bone meal: corn gluten meal = 1:6:1:2). The highest ingestion ratio (the number of pellets ingested/the number of pellets fed) was 0.73 ± 0.03, which was observed in Diet 52. Then five isonitrogenous (52% crude protein) and isocaloric (20 kJ g −1 gross energy) diets were formulated by replacing 0 (control), 35%, 50%, 65% and 80% of fishmeal with No.52 blending proportion. After a 10-weeks feeding trial, a consistent feed intake was found among all replacement treatments. Replacement level of fishmeal up to 35% did not significantly influence final body weight, specific growth rate, feed efficiency ratio, and protein efficiency ratio of turbot. Therefore, the water-soluble extracts of protein sources play an important role in improving the palatability of non-fishmeal protein sources in aquafeed.
