“…The present study shows that the greatest percentages of metamorphosis can be reached in Paracentrotus lividus larvae when they are treated by direct contact with a "metamorphosis stimulating factor", which could be the red macroalgae Palmaria palmata, one of the most common sources of food for sea urchin adults (Vadas et al 2000;Cook and Kelly 2007;Boudouresque and Verlaque 2013) and the most used in the area of this study by grazer invertebrate farmers such as sea urchin or abalone (García-Bueno et al 2016). This method could be viable and profitable for optimising the hatchery production of Paracentrotus lividus.…”

“…Concerning G. turuturu , García‐Bueno et al () highlighted the difficulties, due to a rapid degradation, in using fresh G. turuturu thalli in abalone aquaculture and concluded that it might be more appropriate to use dry or powder form. In the present study, we could not evaluate the use of dried G. turuturu due to high degradation, making its sampling and analysis impossible.…”

“…Linear growth rate (LGR) and specific growth rate (SGR) were calculated according to the formulas (Cook & Kelly, ; Demetropoulos & Langdon, ; García‐Bueno et al, ):

[LGR (mm / day = \frac{()(, Lt - Li)}{t})]

where LGR was the sea urchin growth in test diameter, Lt the test diameter (mm) at time t , Li the initial test diameter (mm) and t the time in days.

[SGR (% per day = 100 \frac{()(, ln Wt - ln Wi)}{t})]

where Wt was the whole sea urchin WW (g) at time t , Wi the initial whole sea urchin WW (g) and t the time in days.…”

The aim of this work was to assess the potential use of different dried macroalgae as food in the rearing of Paracentrotus lividus. Growth, consumption and food conversions were compared in adult sea urchins fed with fresh or dried thalli of four macroalgae species. Six experimental diets were tested: (a) fresh Palmaria palmata; (b) fresh Saccharina latissima; (c) dry P. palmata; (d) dry S. latissima; (e) dry Laminaria digitata and (f) dry Grateloupia turuturu. Linear growth rates were similar for all treatments. Specific growth rate was higher in sea urchins fed with fresh P. palmata, but no difference was found between animals fed with fresh S. latissima and those fed with dried diets. Regarding daily food consumption (DFC), sea urchins consumed the same amount of dried macroalgae as fresh but exhibited a higher food conversion efficiency (FCE) when fed with fresh P. palmata. However, this FCE was only significantly higher when compared to sea urchins fed with dry L. digitata. Dried G. turuturu is not a suitable diet due to its rapid degradation after rehydration. The results suggest that P. lividus adults can be reared on dried macroalgae thalli without detriment to their somatic growth, especially over short periods. The low cost of feeding sea urchins with this diet could help small shellfish farmers to diversify their production into echinoculture.

“…Besides, it improved abalone health and its nutritional composition, since animals showed, by the end of the assay, tissues with higher carbohydrate/protein ratio, ash content, and lower lipid amount [ 153 ]. Other studies in which G. turuturu mixed with P. palmata was used as feed for the European abalone Haliotis tuberculate demonstrated that the combination of algae did not produce animals’ mortality, and it improved growth rates (in length and weight) while increasing the final content of lipid in the abalone [ 154 ]. Besides, in another work, the capacity of G. turuturu was underlined for inhibiting, in a quantity of 16%, the growth of the main pathogen of the H. tuberculata , that is, Vibrio harveyi [ 130 ].…”

The Use of Invasive Algae Species as a Source of Secondary Metabolites and Biological Activities: Spain as Case-Study

In the recent decades, algae have proven to be a source of different bioactive compounds with biological activities, which has increased the potential application of these organisms in food, cosmetic, pharmaceutical, animal feed, and other industrial sectors. On the other hand, there is a growing interest in developing effective strategies for control and/or eradication of invasive algae since they have a negative impact on marine ecosystems and in the economy of the affected zones. However, the application of control measures is usually time and resource-consuming and not profitable. Considering this context, the valorization of invasive algae species as a source of bioactive compounds for industrial applications could be a suitable strategy to reduce their population, obtaining both environmental and economic benefits. To carry out this practice, it is necessary to evaluate the chemical and the nutritional composition of the algae as well as the most efficient methods of extracting the compounds of interest. In the case of northwest Spain, five algae species are considered invasive: Asparagopsis armata, Codium fragile, Gracilaria vermiculophylla, Sargassum muticum, and Grateulopia turuturu. This review presents a brief description of their main bioactive compounds, biological activities, and extraction systems employed for their recovery. In addition, evidence of their beneficial properties and the possibility of use them as supplement in diets of aquaculture animals was collected to illustrate one of their possible applications.
