Effect of casein substitution with fishmeal, soybean meal and crustacean meal in the diet of the abalone Haliotis discus hannai Ino

Abstract

The effect of dietary substitution of casein with fishmeal, soybean meal and crustacean meal on the growth of the abalone Haliotis discus hannai Ino was determined. A 350 g casein per kilogram diet was included into the CS diet. The whole casein was then substituted by: (1) 300 g fishmeal and 200 g soybean meal per kilogram diet (FS), (2) 200 g fishmeal, 200 g soybean meal and 130 g krill meal per kilogram diet (FSK), (3) 200 g fishmeal, 200 g soybean meal and 280 g red crab meal per kilogram diet (FSC) or (4) 200 g fishmeal, 200 g soybean meal and 130 g shrimp head meal per kilogram diet (FSS). In addition, a 50‐g by‐product of green tea per kilogram diet was included in the FS diet to form the FSG diet. Sea tangle (ST)diet was supplied to abalone as a control feed. Weight gain, final shell length and final shell width of abalone fed with the various substitution feeds (FS, FSK, FSC, FSS and FSG) were not different from those obtained with the CS diet. All the formulated feeds, however, produced higher weight gain and final shell width values than the ST diet. The results of this study show that casein can be replaced with a combination of fishmeal, soybean meal, krill meal, crab meal and/or shrimp head meal in the diet without a retardation of growth of abalone.

“…Cho et al (2008) also reported that growth of abalone fed a combined fish and soybean meal d iet or a comb ined fish, soybean and crustacean meal diet was comparable to that of abalone fed a casein-basal diet. In addition, FM at 350 g/kg could be co mpletely replaced with soybean meal at 580 g/kg with an additional 5 g/kg methionine supplementation, as it is lacking in the p lant protein source (Cho, 2010).…”

“…Similarly, MA common ly used as feed in wild did not produce the optimal performance of abalone (Lee, 1998;Cho et al, 2006;Kim et al, 1998;Naidoo et al, 2006;Cho et al, 2008;Gracia-Esquivel & Felbeck, 2009;Dang et al, 2011;Myung et al, 2016).…”

“…As FM and MA are the largest components of commercial abalone feeds and prices continue to increase, alternatively sources need to be identified and their performances evaluated against existing commercial feeds. Globally research has shown that a well formulated feed will produce better growth rates that a single algal species diet (Lee, 1998;Cho, Park, Kim, Yoo, & Lee, 2006;Kim, Lee, Han, Kim, & Park, 1998;Cho, Park, Kim, & Yoo, 2008;Naidoo, Maneveldt, Ruck, & Bolton, 2006;Gracia-Esquivel & Felbeck, 2009;Dang, Li, Speck, & Benkendorff, 2011;Kim et al, 2015;Myung et al, 2016).…”
