“…cultured as macroalgal biofilters (Tenore, 1976;Neori, 1996;Shpigel et al, 1996aShpigel et al, ,b, 1999. Hence, protein content of the three macroalgae used in the present experiment would match the protein requirements described for several species of Haliotis such as H. discus (20%) (Ogino and Kato, 1964), H. discus hannai (20-30%) (Uki et al, 1986a), H. kamtschatkana (30%) (Taylor, 1992) or for H. tuberculata and H. discus hannai (25-35%) (Mai et al, 1995b), although it would be lower than that required for H. midae (47%) (Britz, 1996).…”

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.

“…Although the principal objective of this study was to determine the nutrient uptake efficiency of two algae from the Chilean coast, growth rate and seasonal productivity were also evaluated for U. lactuca, given the importance that the algae could have for the same abalone culture as a food source for adult specimens (Mai et al, 1994;Shpigel et al, 1996;Corazani & Illanes, 1998;Shpigel et al, 1999;Troell et al, 2006) or as a source of propagules for the settlement and feeding of abalone larvae and postlarvae (Muñoz et al, 2012), as well as for other increasingly used purposes, such as a healthy food option for humans (Higashi-Okai et al, 1999;Yamori et al, 2001;Aceves et al, 2005).…”

ABSTRACT. The current study examined the nutrient uptake efficiency of Ulva lactuca and Gracilaria chilensis cultivated in tanks associated with the wastewater of a land-based abalone culture. The experiments evaluated different seaweed stocking densities (1200, 1900, 2600, and 3200 g m -2 ) and water exchange rates (60, 80, 125, and 250 L h -1 ). The results show that both U. lactuca and G. chilensis were efficient in capturing and removing all of the inorganic nutrients originating from the abalone cultivation for all of the tested conditions. Furthermore, an annual experiment was performed with U. lactuca, cultivated at a stocking density of 1900 g m -2 and at a water exchanged rate of 125 L h -1, in order to evaluate seasonal changes in the nutrient uptake efficiency, productivity, and growth rate associated with the wastewater of a land-based abalone culture. The results confirmed high uptake efficiency during the entire year, equivalent to a 100% removal of the NH4, NO3, and PO4 produced by the land-based abalone culture. The growth rate and productivity of U. lactuca presented a marked seasonality, increasing from fall until summer and varying from 0.5 ± 0.2% to 2.6 ± 0.2% d -1 and 10 ± 6.1% to 73.6 ± 8.4% g m -2 d -1 for sustainable growth rate and productivity, respectively. We conclude that there is sufficient evidence that demonstrates the high possibility of changing the traditional monoculture system of abalone in Chile, to a sustainable integrated multi-trophic aquaculture system, generating positive environmental externalities, including the use of U. lactuca as a biofiltration unit.

Eficiencia de absorción de nutrientes de Gracilaria chilensis y Ulva lactuca en un sistema multitrófico integrado con el abalón rojo Haliotis rufescensRESUMEN. Se analizó la eficiencia de captación de nutrientes de Ulva lactuca y Gracilaria chilensis, cultivadas en estanques asociados a aguas de desecho proveniente de un cultivo del abalón rojo Haliotis rufescens. Los experimentos consideraron evaluar diferentes densidades de cultivo de algas (1200, 1900, 2600 and 3200 g m -2 ) y tasas de recambio de agua (60, 80, 125 y 250 L h -1 ). Los resultados mostraron que tanto U. lactuca como G. chilensis fueron eficientes en la captación de nutrientes inorgánicos provenientes del cultivo de abalón, en todas las condiciones probadas, con remoción total de los nutrientes aportados por el cultivo. De la misma forma se realizó un experimento anual con U. lactuca, siendo cultivada con densidad de 1900 g m -2 y tasa de recambio de agua de 125 L h -1 para evaluar cambios estacionales en la eficiencia de captación de nutrientes, así como en la productividad y tasa de crecimiento de U. lactuca. Los resultados confirmaron una alta eficiencia de captación de U. lactuca durante todo el año, equivalente a la remoción del 100% del NH4, NO3 y PO4 aportado por el cultivo de abalón.

“…Uki et al (1985) identified diets containing many protein sources such as soybean meal that promoted good growth in abalone. Mai et al (1995) reported that high levels of dietary carbohydrates can be utilized easily by abalone to satisfy their energy requirements, and Lee et al (1998) suggested that abalone can utilize carbohydrates more efficiently than lipids as an energy source. Considering these results, dietary supplementation using DDG may provide not only sufficient protein, but also energy for body growth and maintenance of juvenile abalone.…”

An 8-week feeding experiment was conducted to determine the influence of dietary distillers dried grain (DDG) on the growth and body composition of juvenile abalone Haliotis discus hannai. Five diets were formulated to contain 0% (DDG0), 15% (DDG15), 30% (DDG30), 45% (DDG45), and 60% (DDG60) DDG, and three replicate groups of abalone (average body weight: 3.6 ± 0.21 g) were fed one of the experimental diets at a feeding rate of 5% body weight per day once daily (17:00 h) for 8 weeks. Survival, shell length, and shell width of juvenile abalone were not affected by dietary DDG levels (P > 0.05). Weight gains of juvenile abalone fed DDG15 and DDG30 diets were not different compared to DDG0, but abalone fed DDG45 and DDG60 diets gained less weight than those fed DDG0 (P < 0.05). Soft body weight/body weight ratio of juvenile abalone fed the DDG60 diet was lower than that of those fed the DDG0 diet (P < 0.05), but proximate composition of the soft body was not affected by dietary DDG levels (P > 0.05). The results of this experiment suggest that DDG is a good replacement for wheat flour and soybean meal, and can be used up to 30% in the diet to maintain the growth performance of the juvenile abalone.
