“…Similar results have been observed for FM alternatives used in diets for other aquaculture species (Gatlin et al 2007). Feed attractants and palatability enhancers may be used to increase consumption of these alternative feedstuffs (Dias, Gomes, & Kaushik 1997;Thiessen, Campbell, & Tyler 2003;Choi et al 2004); however, flavor modifications do nothing to mitigate limitations of nutrient density or availability. Previous work with sunshine bass indicated PM protein was poorly digested (Gaylord, Rawles, & Gatlin 2004), methionine and/or lysine limiting, and an insufficient substitute for FM at 40% digestible protein (∼60% of diet, dry matter) (Gaylord & Rawles 2005).…”

We evaluated production performance and fillet composition of sunshine bass fed increasing levels of stabilized poultry protein meal (PM) and poultry fat (PO) to replace menhaden fish meal (FM) and/or oil (FO) in diets. The control diet included 200 g/kg (dry matter basis) FM and 98 g/kg FO. In eight treatment diets, 50% or 100% of the FM and/or FO were replaced with PM and PO. Each diet was fed to four replicate tanks of juvenile sunshine bass for 10 wks. Survival, food conversion ratio, and liposomatic index were unaffected by dietary treatment, although consumption, growth, and HSI were reduced with complete FM replacement. Fillet lipid content and athero-and thrombogenicity indices differed with lipid source; substitution of FO with PO resulted in marked increases in dietary and fillet monoenes and n-6 fatty acids. Consistent with this, dietary and fillet n-3 and highly unsaturated fatty acids were reduced in fish fed more PO. FM replacement similarly affected fillet fatty acid profile, though to a lesser degree. Our data suggests little to no interaction between FM, FO, and their alternatives in diets for sunshine bass, except with respect to the effect of FO and residual lipids in FM on tissue fatty acid composition.

“…Based on previously published literature and behavioral observations from the present study, palatability of treatment feeds may have been a factor. During the testing of diets and dietary constituents for various finfish species, a growth response (or lack thereof) is often attributed to palatability (e.g., red drum Sciaenops ocellatus: McGoogan and Gatlin 1997; rainbow trout Oncorhynchus mykiss: Glencross et al 2002;Thiessen and Tyler 2003). Observations from the present study indicated that bonytails fed the two shrimp diets (high and low protein) were more active feeders than fish offered the catfish and trout diets.…”

Performance of Endangered Bonytails Fed Four Commercial Diets

et al. 2006

The bonytail Gila elegans is a critically endangered cyprinid that is endemic to the southwestern United States, where it is cultured in ponds and water reuse systems as part of recovery efforts. Unlike in extensive outdoor pond culture, where natural food productivity plays a primary nutritional role, manufactured feed must provide complete nourishment for fish reared indoors in recirculating systems. The objective of this study was to determine the effects of diet on the growth and survival of juvenile bonytails fed four commercially available feeds over a 120-d period. The four treatment diets were identified as a catfish diet, a trout diet, a high-protein shrimp diet, and a low-protein shrimp diet. Significant (P , 0.05) differences in growth among treatments were observed on sampling day 102. By day 120, the average weight of fish fed the high-protein shrimp diet (36.3 g) was significantly higher than the weights of fish fed the catfish (26.6 g), trout (24.7 g), and low-protein shrimp diets (24.2 g). The specific growth rates measured on days 102 and 120 were significantly greater for bonytails fed the high-protein shrimp diet than for fish fed the other treatments. The feed conversion ratio of fish fed the high-protein shrimp diet was significantly better than those of fish fed the trout and low-protein shrimp diets, while the protein efficiency ratio and apparent net protein retention were generally higher in the high-and low-protein shrimp diet treatment groups than in the other two treatment groups. Overall survival was high (93.5%) and did not differ significantly among treatment groups (P ! 0.05) through 120 d.

“…The digestibility in these plant sources is generally lower compared with ¢sh meal in diets of ¢sh. Attempts to improve the digestibility of plant proteins or carbohydrates have included the use of hydrothermal treatments such as extrusion, fractionation of crops to reduce the content of antinutritional factors, increase the protein concentration (Thiessen, Campbell & Adelizi 2003;Thiessen, Campbell & Tyler 2003;Venou, Alexis, Fountoulaki, Nengas, Apostolopoulou & Castritsi-Cathariou 2003) and the use of low inclusion rates of a number of plant protein sources to reduce exposure to individual antinutritional factors (Gomes, Rema & Kaushik 1995;Adelizi, Rosati, Warner, Muench, White & Brown 1998). Each of these approaches has been shown to improve the protein and energy digestibility of plant protein sources.…”

Effects of exogenous enzyme supplementation in diets on growth and feed utilization in tilapia, Oreochromis niloticus x O. aureus

2007

A 12‐week feeding trial was conducted to investigate the effects of supplemental exogenous enzyme on growth performance in juvenile hybrid tilapia Oreochromis niloticus×O. aureus (18 g, average initial weight). A commercial enzyme complex (neutral protease, β‐glucanase and xylanase) was included at the level of 0.0 (control group), 1.0 and 1.5 g kg−1 diet in three test diets. Each diet was fed to triplicate tanks of the juvenile three times a day at 4–6% of wet body weight, and each tank was stocked with 50 fish. The results showed that specific growth rate and feed efficiency ratio significantly increased (P<0.05) with increasing dietary enzyme levels. The highest feed intake was recorded in the group fed the control diet (P<0.05). The highest apparent protein retention was observed in fish fed the diet containing the 1.5 g kg−1diet (P<0.05). No significant differences were observed in the apparent digestibilities (ADC) of protein, lipid and gross energy among dietary treatments (P>0.05). However, the ADC of dry matter in fish fed high supplementation (1.5 g kg−1) was significantly higher than the control and low supplementation (P<0.05). There were no significant differences in condition factor, whole body moisture, protein, lipid and ash among dietary treatments. Viscera ratio, hepatosomatic index and the liver lipid decreased significantly with increasing enzyme (P<0.05). Both protease and amylase activities in the intestine and the hepatopancreas of juvenile hybrid tilapia significantly increased (P<0.05) with increasing dietary enzyme levels. The results suggested that enzyme supplementation can significantly improve growth performance and feed utilization in juvenile hybrid tilapia.
