Effect of the seaweed Macrocystis pyrifera and a formulated diet on growth and fatty acid composition in the green abalone, Haliotis fulgens, under commercial culture conditions

The effect of a formulated diet (FD), a seaweed diet (SW), and a mixture of both (FD + SW) on growth, survival rate, and fatty acid content in the tissue of juvenile Haliotis fulgens abalone grown under commercial culture conditions, was analyzed over a 329-day period. Survival and growth rate in te...

Survival and growth rate in terms of length and weight were different with each of the diets evaluated, being significantly higher (P < 0.05) with the mixed diet (FD + SW), followed by SW and FD. Since feed intake was not evaluated in this preliminary study, differences in growth cannot be attributed to the dietary treatments; however, the importance of this work was to show the significant impact of the diet treatments on the tissue fatty acid profiles, suggesting that the treatments contribute to the composition of some fatty acids found in muscle. The polyunsaturated fatty acid (PUFA) 22:4n-6 was not detected in any of the diets, while 20:4n-3 was only present in SW and 22:5n-3 only in FD. However, after the feeding experiment all these PUFAs were present in abalone tissue. The possible synthesis of PUFAs from dietary n-3 and n-6 fatty acids of shorter hydrocarbon chain is discussed. Se analizaron los efectos de una dieta formulada (FD), de una dieta de macroalgas (SW) y de la mezcla de ambas (SW + FD) sobre el crecimiento, la tasa de supervivencia y la composición de ácidos grasos en el tejido de juveniles de abulón azul, Haliotis fulgens, en un cultivo comercial durante un periodo de 329 días. La tasa de supervivencia y el crecimiento en términos de longitud y peso, mostraron diferencias significativas entre los tratamientos estudiados, siendo significativamente mayores (P < 0.05) para la dieta FD + SW, seguida por las dietas SW y FD. Dado que la tasa de consumo no pudo ser evaluada en este experimento preliminar, las diferencias encontradas no pueden ser atribuidas a los diferentes tratamientos; sin embargo, la importancia de este trabajo consistió en mostrar el impacto de los tratamientos sobre los perfiles de ácidos grasos contenidos en el tejido de los abulones, lo cual sugiere que los tratamientos contribuyeron en la composición de algunos de los ácidos grasos encontrados en el músculo. El ácido graso poliinsaturado (PUFA) 22:4n-6 no fue detectado en ninguna de las dietas, mientras que el 20:4n-3 estuvo presente sólo en la SW y el 22:5n-3 sólo en la FD. Sin embargo, al finalizar el experimento todos estos PUFAs estuvieron presentes en el tejido de abulón. Se discute la posible síntesis de los PUFAs a través de los ácidos grasos n-3 y n-6 de cadena más corta presentes en la dieta.
