Effect of dietary seaweed extract supplementation on growth, feed utilization, hematological indices, and non-specific immunity of Nile Tilapia, Oreochromis niloticus challenged with Aeromonas hydrophila

Impact of Seaweed Liquid Extract Biostimulant on Growth, Yield, and Chemical Composition of Cucumber (Cucumis sativus)

“…Marine aquatic organisms are an important source of bioactive compounds [57,58]. In the current study, concerning the GC-MS analysis [13,59,60], the NIST (National Institute of Standards and Technology) mass spectral library identified nine compounds in TAM ® (Figure 1). Most compounds had a long hydrocarbon chain, such as nonadecane (alkane), rhodopin (carotenoid), oleic acid (fatty acid), phytol (diterpene alcohol), milbemycin oxime (macrocyclic lactones), and the fatty acid methyl esters (FAMEs) (tridecanoic acid methyl ester, γ-linolenic acid methyl ester, and 9,12-octadecadienoic acid, methyl ester, (E,E)-).…”

“…According to Ashour et al [13], the physical, chemical, and biochemical analyses of TAM, which were used in the current study as biostimulator foliar sprays for cucumber (Table 2), show that TAM has a dark brown color, a seaweed odor, a density of 1.2, and a pH of 9-9.5. TAM showed large amounts of macronutrients, including K (15%) and P (2.4%), while small amounts of N (0.1%) were reported.…”

“…TAM is a commercial seaweed liquid extract, submitted as a patent [11]. The preparation of TAM was as described by [13]. In detail, three seaweed species, Ulva lactuca (Chlorophyceae), Jania rubens, and Pterocladia capillacea (Rhodophyceae), were employed in preparing and producing TAM.…”

“…After being harvested, the epiphytic and waste materials were removed, then samples were washed, air-dried, powdered, and finally kept in plastic bags at room temperature for further analysis. Phytochemical, physical, chemical, and biochemical analyses of crude TAM were conducted and estimated as described by Ashour et al [13], as presented in Figure 1 and Tables 1 and 2.…”

“…On the other hand, seaweed extracts could be used in various biological processes in industry [11]. Moreover, the use of algal cells and/or their extracts as aquaculture feeds enhances aquatic growth and immunity [12][13][14]. Seaweeds are qualified to be used as biofertilizers, not only because they have a biological impact, but also because of their biocompatibility as they share common biological compounds with plants.…”
