Use of Biochemically Improved Shrimp Industry Waste in Fry Tilapia (Oreochromis Niloticus, Linnaeus 1758) Diets: Effects on Growth Performance and Carcass Composition

Abstract

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

Practical feeds for juvenile Nile tilapia (Oreochromis niloticus) prepared by replacingRastrineobola argenteafishmeal with freshwater shrimp (Caridina nilotica) and mung bean (Vigna radiata) meals

“…Although shrimp meal is nutrient rich, several studies have shown that diet digestibility and fish growth are compromised when high proportions are used (Diop et al., ; Fall et al., ; Mugo‐Bundi et al., ; Synowiecki & Al‐Khateeb, ). Shrimp meals made from shrimp shells may contain relatively high amounts of indigestible fibres (chitin and chitosan), which build up when high proportions are used in diet (Fall et al., ; Synowiecki & Al‐Khateeb, ) and make nutrients less accessible by fish (Leal, Castro, Lima, Souza Correia, & Souza Bezerra, ).…”

Furthermore, the fibres interfere with emulsification, absorption and utilization of fats by fish (Deng et al., ; Diop et al., ). The chitin absorbs fats and bile in fish intestine (Tharanathan & Kittur, ) and reduces their availability for usage by fish.…”

Effects of Partial Substitution of Fishmeal by Crustacean (Callianassa) Meal on the Growth Performance, Feed Efficiency and Survival Rate of Nile Tilapia (Oreochromis niloticus)

“…Fall et al (2012) reported that fish fed diet containing shrimp meal (SM) gained weight slightly less than those fed diet containing fishmeal. Diop et al (2013) revealed that the incorporation of shrimp by-products in the diets of tilapia at 45% gave the best weight gain (4.96 g) compared to the control diet. Several authors (Jung et al, 2006;Wenhong et al, 2008;Uno et al, 2010;Laila et al, 2010) have highlighted that there exist three methods of waste utilization from aquaculture or wild stocks, which are fishmeal, silage and organic fertilizer productions.…”

Utilization of cinnamon Cinnamomum burmannii leaves and shrimp head in the feed on growth performance of catfish Pangasianodon hypopthalmus

“…Several studies have been done on the inclusion of shrimp head meal in the fish feed formulation. Shrimp head meal in the fish diet increased daily growth rate (DGR), feed efficiency (FE), protein efficiency ratio (PER), survival and protein content of the fish (Fall et al, 2012;Diop et al, 2013). Moreover, Melati et al (2012) stated that shrimp head meal could be used to replace fishmeal protein up to 45% in the feed formulation for catfish in hatcheries.…”
