“…This finding is in agreement with a study on M. rosenbergii since among various vegetable oils, that included CO, LSO, sunflower seed oil or crude palm oil (CPO), prawns fed the CPO-based diet had the lowest growth performance [18]. Kim et al [18] suggested that since SFA were poorly digested by P. monodon [27,28] this might have applied to M. rosenbergii thus leading to lower growth.…”

The feasibility of different vegetable based lipids as a complete replacement to dietary fish oil (FO) to blue swimmer crab Portunus pelagicus juveniles was assessed. A total of five iso-nitrogenous and iso-lipidic diets were formulated to contain FO, soybean oil (SBO), linseed oil (LSO), canola oil (CO), or palm oil (PO) as the main lipid source. The diets were fed to first staged juvenile crabs (total of 45 replicate crabs/treatment) over at least four molts. After 35 days, final sizes and weights were determined, and then measured for whole-body cholesterol. Crabs fed the FO, SBO, LSO, or CO-based diets showed similar specific growth rates (SGR) (p > 0.05) for carapace length and width, which was significantly higher (p < 0.05) compared to crabs in the dietary PO treatment. Whole-body cholesterol content was significantly lower for crabs fed the PO-based diets, which may have contributed to their poorer performance, compared to those fed the FO, LSO or CO-based diets. Results indicate SBO, LSO or CO can totally replace FO, which may improve cost-effective and sustainable diets for portunid crabs. Further research into the use of dietary PO blends with other vegetable oils should be conducted.

“…Moreover, significant differences were present between feeds at every salinity level. In the bioassays, lipid digestibility coefficients were higher than those reported by Merican & Shim (1995), Ramos et al (2001) and Lin et al (2006) concluded that the method of preparing feed affects lipids and certain fatty acids ADCs due to autooxidation. Digestibility of feed can be caused by numerous factors, including the presence of enzyme inhibitors in the diet, inappropriate diet formulation, and proteins that are chemically or physically undigestable (Oujifard et al 2012).…”

Digestibilidad aparente de carbohidratos y lípidos en alimentos para camarón blanco, Litopenaeus vannamei (Decapoda: Penaeidae), cultivados en diferentes salinidades. Whiteleg shrimp, Litopenaeus vannamei is one of the most commercially farmed species worldwide because of its fast growth, good survival rate at high farming densities, and osmoregulatory capacity, which makes it an excellent candidate for cultures at different salinities. The knowledge of shrimp nutritional requirements is critical in the formulation of diets to allow optimal growth at different environmental conditions and development stages. The effect of salinity on apparent digestibility of shrimp feed is not well known, and this information is required in shrimp diet formulation. For this purpose, the apparent digestibility coefficients of carbohydrates (ACD) and lipids (ALD) were determined for juvenile whiteleg shrimps under controlled culture conditions. We evaluated the apparent digestibility of six commercial (D1:37CP, D2:38CP, D3:39CP, D4:34CP, D5:35CP, and D6:37CP) and two experimental (E1:33CP and E2:33CP) diets for juvenile whiteleg shrimp cultivated at three salinities (5, 35 and 50psu) in 60L aquariums. ACD and ALD were determined in vivo using chromic oxide as an inert marker. Our results showed that ALD in most cases was over 80%, independent of salinity, except the E1:33CPdiet which had 74.0% at 50psu. Diet D3:39CP showed the highest ALD coefficient (90.1 and 90.6% at 5 and 35psu, respectively). For ACD, differences were detected between commercial and experimental diets at every salinity level, although salinity effect on ACD was not significant. Diet D4:34CP had the highest coefficient (92.4%) at 5psu, and E2:33CP at 35 and 50psu (97.3 and 94.7%). This study demonstrated that there is no significant effect of saline variations on carbohydrate and lipid digestibility by juvenile whiteleg shrimp, under the experimental conditions. Rev. Biol. Trop. 61 (3): 1201-1213. Epub 2013 September 01.Key words: diets, Litopenaeus vannamei, different salinities, digestibility.Feed is the main source of waste and responsible for most of the environmental impacts of aquaculture. The quantity and quality of the waste excreted by shrimp depend on ingestion, digestion, and metabolism of dietary compounds (Amirkolaie 2011). Valdez et al. (2008) reported that the highest energy from the food consumed by juvenile whiteleg shrimp Litopenaeus vannamei is obtained when they are maintained at 26 practical salinity units (psu). However, in areas with high evaporation rates, such as the coast of the States of Sonora and Sinaloa, Mexico (Martinez-Cordova et al. 2009), the levels of salinity are much higher and it could be of great interest to examine if the diets' performance is affected by that condition. Diets that fulfill nutritional requirements at the lowest cost and lowest impact to the environment become imperative; in that context, digestibility of the ingredients needs to be accurately determined (Cruz-Suarez et al. 2001, Campaña-Torre...

“…Many factors strongly affect lipid digestibility (Lee and Lawrence, 1997), including heat treatment. ESBM is an excellent source of triglycerides and phospholipids (Pierce et al, 1969) that can be more efficiently digested than free fatty acids (Merican and Shim, 1995). Although the quantitative level of lipids in the experimental diets was similar, the relative proportions of different fatty acids and their availability possibly varied with the inclusion level of ESBM, which could partially explain the growth enhancement observed in shrimp.…”

Extruded soybean meal (ESBM) was evaluated as a protein source for partial replacement of fish meal (FM) in diets of juvenile Litopenaeus vannamei. In the control diet (Diet 1), FM protein was replaced with increasing dietary levels of ESBM (4.28%, 8.40%, 12.62%, 16.82%, and 25.26%) at 10%, 20%, 30%, 40%, and 60% levels (Diets 2 to 6, respectively). An eight-week feeding trial was conducted on 720 juvenile shrimp (0.67 g ± 0.01 g mean initial weight), and nutrient digestibility of the six diets was determined. ESBM could replace 20% of FM without causing a significant reduction in growth of shrimp, but other dietary treatments strongly affected whole body composition. Crude protein content of the whole body fed Diet 6 was significantly lower than that fed Diet 2 (P < 0.05), while crude lipid content of the whole body fed Diet 5 or 6 was significantly higher than that fed Diet 2 (P < 0.05). Protein digestibilities of Diets 5 and 6 were significantly lower than that of Diet 1 (P < 0.05). Digestibility of lipids ranged from 96.97% in Diet 6 to 98.34% in Diet 3, whereas dry matter digestibility decreased with increasing replacement level. This study indicates that 20% FM replacement with ESBM in the basic diet containing 40% protein and 30% FM is optimal for juvenile L. vannamei.
