The effects of fish meal (FM ) and macroalgae (M A) substitution with fermented soybean meal and rice bran were tested on a commercial diet in juvenile abalone. Abalone (21600) individuals were distributed equally to four diet treatments. Four experimental diets were prepared: a Std diet, FM 50, FM50+M A50 and FM50+MA100. The standard diet (Std) consists of FM (140 g/kg), fermented soybean meal (250 g/kg), corn gluten meal (34 g/kg), shrimp meal (30 g/kg), wheat flour (200 g/kg), dextrin (50 g/kg) and M A (250 g/kg). Undaria and Laminaria were also prepared. The feeding trial lasted for 16 weeks. Survival of abalone fed the formulated diets was higher than that of abalone fed the Undaria and Laminaria. Weight gain and specific growth rate of abalone fed the Std diet were higher than all other diets. Substitutability of the fermented soybean meal for FM seemed to be rather limited in the commercial diet for abalone farms. However, another 500 g/kg M A in the commercial diet could be substituted with rice bran as long as 500 g/kg M A were substituted with rice bran. The FM 50+M A50 diet is the most recommendable for abalone farm in considering feed cost.

“…This low lipid requirement has been associated by some authors (Durazo-Beltrán et al, 2004) with the low use of dietary lipids as energy source by abalone based upon its low metabolic rate. Indeed, high levels of dietary lipid seem to negatively affect abalone growth (Thongrod et al, 2003). However, high levels of carbohydrate enhance growth (Thongrod et al, 2003) of abalone which has various enzymes capable of hydrolysing complex carbohydrates (Fleming et al, 1996) and a good capacity to synthesize non-essential lipids from carbohydrates.…”

In the present study, carbohydrate values (28-33% DW) were high and comparable to those obtained for other algal species (Kaehler and Kennish, 1996;Foster and Hodgson, 1998).…”

Suitability of three red macroalgae as a feed for the abalone Haliotis tuberculata coccinea Reeve

A 60-day feeding trial was conducted to assess the suitability of three red algae, Hynea spinella, Hynea musciformis and Gracilaria cornea, as potential feed for the culture of juvenile abalone, Haliotis tuberculata coccinea R. Seaweeds were reared in a biofiltration unit with fishpond waste water effluents. The three algal species were found to contain high protein contents which would be related to its production under the high nitrogen culture conditions of the biofilter system. Protein and carbohydrate contents were highest in H. musciformis and lowest in G. cornea. Survival rates of juvenile abalone were very good, regardless of the algae fed. Feed intake of H. spinella was highest, followed by H. musciformis. Growth rates of abalone were within the range obtained under commercial conditions, final shell length and weight being significantly highest in animals fed H. spinella and lowest in those fed G. cornea. Feeding G. cornea lead to the lowest growth performance due to the lowest feed intake, whereas feed conversion ratios were significantly highest for H. musciformis and protein efficiency ratios were higher for both H. spinella and G. cornea. This study suggested the good potential of any of the three red seaweeds testedsuccessfully produced by the biofilter system, their nutritional composition being similar to other macroalgae used as feed for abalone and matching the abalone protein and lipid requirements-hence promoting growth and survival. Nevertheless, the biofilter produced macroalgae H. spinella showed the highest dietary value for juvenile of H. tuberculata coccinea.

“…In Penaeus monodon Fabricius juveniles, survival was affected by carbohydrate levels, and trehalose promoted better growth than sucrose and glucose (Alava and Pascual, 1987). Thongrod et al (2003) suggested that the optimal dietary cornstarch level for Haliotis asinine Linne was 47.81%. Rosas et al (2000) found that 33% of dietary carbohydrates limited the growth of Litopenaeus stylirostris juveniles.…”
