“…Throughout the feeding period the fish in all experimental groups were in good health and dose-related mortalities were not observed, indicating that Nile tilapia can tolerate GRC levels up to 5 g/kg diet, albeit with reduced growth rate and increased feed conversion ratio. The adverse effect of coffee-enriched diets on fish growth was reported by Fagbenro and Arowosoge (1991), Moreau et al (2003), and Ulloa and Verreth (2003). Chatzifotis et al (2008) reported that sea bream, Sparus aurata did not accept a caffeine-containing diet at 10 g/kg, but at doses ≤5 g/kg caffeine appeared to have no detrimental effect.…”

This study was conducted to use ground roasted coffee bean (GRC; Coffee arabia) as a feed supplement in diets for Nile tilapia, Oreochromis niloticus. Fish (1.9 ± 0.03 g) were fed diets containing 0.0, 0.5, 1.0, 2.0, or 5.0 g GRC/kg in triplicate for 10 weeks. Final fish weight, weight gain, and specific growth rate were not significantly (P < 0.05) affected by GRC incorporation up to 1.0 g/kg, after which growth declined. Fish fed diets containing 2.0 and 5.0 g GRC/kg consumed less than the other treatments, giving the highest FCR (1.4 and 1.5, respectively). No significant differences were observed in fat efficiency ratio, protein efficiency ratio, and energy utilization for the 0.0-1.0 GRC/kg diets; lowest values of these parameters were obtained with the 2.0 and 5.0 g GRC/kg diets. Supplementation of GRC significantly reduced fish whole-body protein content and increased lipid and ash.

“…Estimates of the digestible energy (kJ) content in feed were calculated using the default apparent coefficients of digestibility of 0.9, 0.85, and 0.8 for crude protein, crude fat, and carbohydrates (NFE), respectively (Moreau et al 2003). …”

Growth response, body composition and fatty acid profile of Caspian brown trout (Salmo trutta Caspius) juvenile fed diets containing different levels of soybean phosphatidylcholine

2010

We investigated the effects of soybean phosphatidylcholine (PtCho) on the growth, fatty acid (FA) profile, and body composition of juvenile Caspian brown trout. Juvenile trout, initial average weight 0.8 ± 0.12 g, were fed semi-purified formulated diets supplemented with 2, 4, and 6% PtCho for 5 weeks. Results showed that fish with diets containing 4 or 6% PtCho had significantly greater growth. The FA profiles of both the polar lipids (PL) and neutral lipids (NL) in juvenile tissues were influenced by dietary FA, although the effects of PtCho supplementation were more marked for PL than for NL. Fish fed PtCho in the diet also had higher levels of 18:2n-6, 20:4n-6 and n-6, and significantly lower levels of docosahexaenoic acid and eicosapentaenoic acid in both PL and NL. The lipid contents of whole-body tissues and liver were positively affected by PtCho percentage in the diet. Specific growth rate, hepatosomatic index, visceralsomatic index, and protein efficiency ratio were also significantly influenced by dietary PtCho. The results of our study indicate that dietary PtCho has a growth-promoting effect and that juvenile Caspian brown trout have a relatively moderate PtCho requirement (at least 4% dry weight of the diet).

“…Piauçu, Leporinus macrocephalus (a South American Anostomid), is a species that has recently been commercially cultured for human consumption with a growing aquacultural activity in South America (Albrecht et al, 2001). Accordingly, techniques to improve piauçu growth are very interesting goal for aquaculture practices in which growth rate represents an economically important trait (Moreau et al, 2003;Barreto et al, 2003). Betaine could be a possibility for improving piauçu growth rate.…”

In this study was tested the effect of betaine on the growth performance of the piauçu fish. For this, twenty-one fish (mean ± SD: body weight: 14.9 ± 1.3 g) were randomly distributed in one out of three experimental treatments (n = 7 each; 1 fish/aquarium): without betaine added in the food (control); 3.6 g betaine/Kg of food; 7.1 g betaine/Kg of food. The fish were exposed to experimental conditions for 60 days. Fish presented significant growth throughout experimentation, but no statistically significant difference was found for any parameter analyzed among the treatments, except for condition factor, which was higher in control group than betaine ones. Accordingly, it was concluded that betaine had no enhancing effect on growth of piauçu.Abbreviations: SGR -specific growth rate; FCE -food conversion efficiency; FI -food intake; K -condition factor; TGC -thermal-unit growth coefficient
