“…Limited growth of abalone in all experimental groups, even though for 120-days period, may be related to the absence of dietary ARA and EPA. Similarly, lower growth rate was also observed in abalone fed diets containing lower levels of n-3 LC-PUFA (Mateos et al, 2013). The present study confirmed the contributing effects of EFA (LA and ALA) on growth of abalone in comparison with the group fed diet without EFA supplementation.…”

“…H. tuberculata growth seemed to be highly correlated to n-3 poly-unsaturated fatty acids (PUFA) in algal composition as demonstrated by Mai et al (1996) with a SGR of 1.31 % day -1 when fed a P. palmata diet containing the highest amount of n-3 PUFA (49.7% of total fatty acids) compared to a SGR of 1.03 % day -1 when fed L. saccharina diet containing the lowest n-3 PUFA (25.2% of total fatty acids). A lower SGR (0.30 % day -1 ) was also observed in Jade tiger hybrid abalone fed canola oil diets containing lower levels of n-3 PUFA (12.5% of total fatty acids) compared to a higher SGR (0.47 % day 1 ) when fed fish oil diet containing more n-3 PUFA (27.5 % of total fatty acids) (Mateos et al, 2013). In our experiment, total PUFAs were not related to growth enhancement.…”

The commercial culture of Haliotis tuberculata has recently started in Europe. As abalone is herbivorous, the use of local collected algae as feed may appear advantageous. The nutritional value of eight monospecific seaweed diets was studied using Palmaria palmata (Rhodophyta), filamentous algae, mainly Gracilaria sp. (Rhodophyta), Enteromorpha sp. and Ulva lactuca (Chlorophyta), together with Saccharina latissima, Saccorhiza polyschides, Laminaria digitata and Laminaria hyperborea (Ochrophyta, Phaeophyceae) and a mixed macroalgal diet. An integrative approach consisted in monitoring the seasonal composition changes of these algae in terms of protein, lipid, soluble carbohydrate, fatty acid and amino-acid contents, and to relate it to seasonal growth and reproduction investment during a largescale experiment. Abalone and algae were studied for one year in commercial sea-cage structures. Abalone fed with monospecific diet using either P. palmata or S. latissima, and with mixed diet presented the best growth rate, muscle ratio and gonad development. Seasonal daily weight gain was mainly associated with n-3/n-6 ratio, soluble carbohydrate content and total protein content. In term of aminoacid contents, the daily weight gain was associated with free phenylalanine as well as isoleucine levels. Moreover, 90% of 2-years old abalone started gonad development but less than a quarter featured a fully matured gonad. The gonad development of H. tuberculata was mostly associated to total valine, methionine, leucine, arginine and isoleucine levels. The age of initial sexual maturity in H. tuberculata turned to be a highly plastic trait in response to different growth rates and algal diets. Even if P. palmata is the best option for growth performance, mixed diets should probably be preferred to a monospecific diet in order to avoid too high pressure on a single algal resource. Highlights ► Mixed diets conferred higher fitness than the average of single-species diets, but not for the best single species ► Abalone are likely to invest more energy in muscle and gonad developments when fed on Palmaria palmata. ► At 2-year-old, an average of 90% of H. tuberculata started gonad development but <23% of the cohort had a full development ► Soluble carbohydrate, n-3/n-6 and total protein are the major algal components for reproduction and growth performance

The growth performance of Jade Tiger cultured abalone fed diets supplemented with fish oil and vegetable oils

Abstract: Supplementation with 1.5% of dietary FO can improve growth performance in cultured abalone. It is feasible to replace 75% of dietary FO with FlaxO and 50% of dietary FO with CO, without negative effect on growth performance.
