“…had been used to support the growth of aquatic organisms. In a previous study, Ulva lactuca had been developed as a supplement for catfish and tilapia (Abdel-Warith et al 2016;Mahasu et al 2016), while Ulva intestinalis was explored used as an ingredient for tilapia (Siddik et al 2015). Ulva reticulata had also been reported to be a supplement that supported the growth and health of goldfish (Rama et al 2014).…”

Abstract. Tarigan N, Sudrajat AO, Arfah H, Alimuddin A, Wahjuningrum D. 2023. Potential use of phytochemical from ethanolic extract of green seaweed Ulva reticulata in aquaculture. Biodiversitas 24: 6868-6879. Ulva reticulata is green seaweed with potential phytochemical properties in the aquaculture sector. Therefore, this study aims to determine phytochemical components and evaluate the toxicity of Ulva reticulata ethanolic extract on aquatic animals. The primary constituents in the sample were extracted using the maceration method with 96% ethanol. The antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, while toxicity level was determined using the Brine Shrimp Lethal Test (BSLT) method at concentrations of 0, 10, 100, 300, 500, 1000, and 2000 mg L-1. The results showed that Ulva reticulata ethanolic extract was qualitatively composed of alkaloids, flavonoids, saponins, tannins, phenols, and steroids with mid (++), low (+), low (+), low (+), low (+), and mid (++) activity levels, respectively. Based on quantitative analysis, the sample was composed of sitosterol (19.01 mg g-1), stigmasterol (35.00 mg g-1), saponins (17.04 mg g-1), flavonoids (82.16 mg QE 100 g-1), total phenols (144.00 g QE 100 g-1), and tannins (49.03 mg g-1). Furthermore, Ulva reticulata ethanolic extract had a strong antioxidant level with a 50% inhibitory concentration (IC50) of 53.00 ppm. The toxicity test showed that the 50% lethal concentration (LC50) of the sample was 481.86 mg L-1. These results showed that Ulva reticulata ethanolic extract was a non-toxic material with a high potential for phytochemical properties that could be beneficial for fish growth, reproduction, and health.

“…In this sense, positive effects on weight gain, specific growth rate, and feed use efficiency have been notified for most species when rates are less than 10% of the dry weight of the feed [4,5,39,40]. In contrast, levels of around 10% do not determine changes in the mentioned parameters [6][7][8]41], but higher amounts of 20% or more negatively affect growth parameters [7,9,10,41]. Considering all these preliminary results, in the present work two levels of dietary inclusion, i.e., 5% and 8%, were evaluated.…”

“…Hence, positive effects on growth and feed efficiency have been reported at incorporation rates accounting for less than 10% of the dry weight of the feed [4,5]. In contrast, levels exceeding this amount either do not result in significant effects [6][7][8] or produce negative results [9,10]. In this sense, it has been suggested that the presence of protease inhibitors may limit digestive use of this seaweed in several fish species such as the Senegalese sole (Solea senegalensis), the gilthead seabream (Sparus aurata), or the European sea bass (Dicentrarchus labrax,) and hence limiting growth performance and feed use [11].…”

This study evaluated the use of Ulva ohnoi as an ingredient in feeds for aquaculture in three different experiments. Experiment 1 was oriented to confirm the negative effect of U. ohnoi on fish digestion. Experiment 2 assessed the effect on growth, feed efficiency, and immune status of juvenile sea bass (Dicentrarchus labrax) fed on diets including U. ohnoi, previously treated or not with carbohydrases used to partially hydrolyze indigestible polysaccharides. Experiment 3 was aimed to evaluate the potential protective effect of U. ohnoi on the oxidative status of sea bream (Sparus aurata) challenged by the consumption of a feed formulated with the oil fraction completely oxidized. Results show a negligible effect of U. ohnoi meal on protein digestion when included in feeds at levels of 10% or less. Moreover, results of growth and feed use evidenced the possibility of using up to 5% inclusion of algal meal in feeds without adverse effects on the zootechnical parameters, while the enzyme pretreatment was ineffective to improve its nutritional use. Finally, the inclusion of U. onhoi in feeds determined both an immunostimulatory effect, evidenced by an increase in skin mucus lysozyme in the two mentioned fish species, and a positive influence on the oxidative metabolism of seabream when fed on a diet including rancid oil.
