“…These fibers are mainly constituted of chitin (30% to 40% of the shrimp shell) and chitosan. These results are in contradiction with the observations of Shiau & Yu (1999), Fall et al (2012) and Leal et al (2009). According to these authors, the decrease in growth performance observed from high inclusion level of shrimp waste meal could be explained by poor digestion of chitin.…”

To evaluate the nutritional quality of the shrimp by-products four approximately isonitrogenous (32 ± 2% crude protein) diets containing different types of shrimp waste meal were fed to duplicate groups of ten fry with an initial mean weight 1.43 ± 0.22g /fish for forty two (42) days. Fishes fed with diet D had the highest mean weight gain (MWG) and specific growth rate (SGR) and those fed with the control diet A had the lowest MWG and SGR. ISSN 2157-6076 2013 www.macrothink.org/jbls 330 There were no noticeable change in food conversion ratio (FCR) of the fishes fed with diets B, C and D which are significantly different from the FCR of those that fed with control diet A. The survival of fry tilapia ranged from 70 to 100%, being 70% for D, 80% for B, 90% for C and 100% for A. There were no significant differences in body protein content among the fish fed with diets B, C, D and the initial fish. The lowest body protein was obtained in the fish fed with control diet. The tilapia fed with control diet had the highest body lipid content as compared to the initial fish. However, there were no significant differences in body lipid content among the fish fed test diets B, C and D as compared to the initial fish. The variations in body ash content of initial fish and those fed with test diets were significantly different. The initial fish had the highest body ash content. Journal of Biology and Life Science

“…For instance, in red tilapia, O. niloticus 9 O. hornorum and nile tilapia, dietary fishmeal could be significantly replaced with shrimp meal, which is a rich source of chitin, without any adverse effects on the fish performance (El-Sayed 1998;Mansour 1998). Conversely, in the other species of tilapia, O. niloticus x O. aureus, the inclusion of chitin depressed growth (Shiau and Yu 1999). Our observations from the present study suggest, barramundi, Lates calcarifer might have limited efficiency to digest chitin thereby insect meal.…”

The present experiment was conducted to evaluate the efficacy of dietary protein from black soldier fly, Hermetia illucens, larval meal (BSFL) to replace fish meal (FM) protein in juvenile barramundi, Lates calcarifer. Larvae of black soldier fly were fed with the underutilised crop, sesbania, Sesbania grandiflora. Five isonitrogenous (44% crude protein) and isocaloric (16.0 kJ available energy/g) experimental diets were formulated to replace FM using processed BSFL meal at 0 (control), 25% (BSFL25), 50% (BSFL50), 75% (BSFL75) and 100% (BSFL100). Data for proximate and amino acid analysis suggested BSFL meal as an inferior protein ingredient than FM, but parallel to soybean meal. At the end of 8 weeks of fish feeding trial, there were no significant differences in the average weight gain (WG) and specific growth rate among the group of fish-fed control, BSFL25 and BSFL50 diets (P \ 0.05). Although numerical differences were recorded in the fish whole-body proximate composition, crude protein and moisture content were not much affected by the different dietary treatments. Essential amino acids including arginine, histidine, lysine and methionine were found to be higher in the whole body of fish-fed BSFL100 diet. Broken line regression analysis of average WG showed an optimum FM replacement level of 28.4% with BSFL meal. Therefore, the present experiment clearly demonstrates that the maximal dietary inclusion level of BSFL meal as FM protein replacer for the optimum growth of juvenile barramundi reared in freshwater could be greater than 28.4% but less than 50%, without any adverse effects on the fish whole-body proximate and amino acid composition.

“…Chitin is a complex carbohydrate that forms the structural part of the exoskeleton of crustaceans and constitutes 15-30% of their total weight (Garzón et al, 1993), most probably contributing to the low ADC for dry matter and ingredients obtained in our study. This coincides with the observations of Shiau and Yu (1999), who reported low ADC DM by tilapia when using diets with high chitin content. Yet, despite the low digestibility coefficients observed for the RC diet, the protein efficiency ratio of tilapia obtained when using this diet was high and similar to those obtained with the fish silage and whey meal diets ( Table 8 -Regression equations relating response of digestibility, growth, feed, blood parameters, and enzyme performance ADC ICP -apparent digestibility coefficient of crude protein of ingredients; PER -protein efficiency ratio; ADC CP -apparent digestibility coefficient of crude protein of diet; FBW -final body weight; TL -total length; WG -weight gain; FCR -feed conversion ratio; FER -feed efficiency ratio; chy -chymotrypsin activity; SGR -specific growth rate; HEM -hematocrit.…”

-In this work, we studied the digestibility, growth, blood chemistry, and enzyme activity of Nile tilapia (Oreochromis niloticus) juveniles (0.95±0.18 g) using different animal (fish silage meal, whey meal, bovine blood meal, and red crab meal) and plant (extruded bean, extruded chickpea meal, coconut paste, Jatropha curcas meal, and chickpea meal) dietary byproducts. Nine isocaloric diets (321.92±9.10 kcal g −1 ) were evaluated for 60 days. The highest digestibility of crude protein values for animal and plant sources were obtained for the whey (93.6) and extruded bean meal (90.5) diets, respectively. The final body weight was higher for the red crab and extruded chickpea meal diets, meanwhile the fish silage and red crab byproducts obtained the highest protein efficiency ratio. Hematocrit was similar among the diets of each byproduct source and presented correlation with growth parameters. The highest glucose, cholesterol, and triglyceride values were obtained for fish silage (138.0, 260.5, and 389.0 mg dL −1 , respectively) and whey meal (174.5, 242.3, and 284.0 mg dL −1 , respectively) groups. A positive correlation was found between the digestibility of crude protein of ingredients and chymotrypsin activity. Oreochromis niloticus is able to better utilize fish silage, whey, extruded bean, and extruded chickpea byproducts, adjusting its digestive physiology. Such ingredients can be used for formulating cheaper and efficient tilapia diets.Key Words: alternative byproducts, digestive response, formulated diets, growth performance, Nile tilapia, physiology Revista Brasileira de Zootecnia
