“…In feeding trials using Artemia fed various concentrations of hot water extracts of S. wightii or S. duplicatum seaweeds, growth performance of P. monodon PL15 was higher (294 and 323 mg weight gain and 16.6 and 17.1% SGR, respectively) when Artemia had been fed an extract concentration of 750 mg l −1 compared with a lower concentration of 250 mg l −1 (274 or 295 mg weight gain and 16.3 or 16.6% SGR, respectively) (Immanuel et al 2010). Consistent with this, improved growth performance has been noted in P. indicus juveniles fed Artemia nauplii enriched by feeding upon crude extracts of Ulva lactuca and S. wightii seaweeds (Immanuel et al 2004) and in Atlantic halibut Hippoglossus hippoglosus larvae fed Artemia enriched by feeding upon alginate high in mannuronic acid (Skjermo & Bergh 2004).…”

Sodium alginate extracted from brown seaweed Sargassum wightii (16.35 ± 1.42%, mean [± SD] yield from 5 extractions) was prepared as a powder or beads and used to enrich Artemia nauplii at concentrations of 100, 200, 300 and 400 mg l −1 . The alginate-enriched nauplii were fed to Penaeus monodon shrimp postlarvae (PL) stage 15 (PL15, i.e. 15 d old) for 20 d. Mean weight gain and specific growth rate over this period were 0.24 g and 15.8%, respectively, in PL groups not fed alginate, and 0.20−0.28 g and 14.7−16.5%, respectively, in PL groups fed alginate. Amongst PL35 then challenged with white spot syndrome virus (WSSV) by immersion, all PL not fed alginate died within 9 d. However, amongst PL fed the 4 concentrations of alginate powder or beads, mortality rates reduced with increasing alginate concentration, and between 25 and 32% PL remained alive when the bioassay was terminated on Day 21. Amongst alginate-fed PL groups compared with the control group, mortality was reduced by 26.5 to 58.4%. Nested PCR detection of WSSV revealed sodium alginate concentration-dependent reductions in infection loads. The data indicate that sodium alginate extracted from brown seaweed and fed to P. monodon can retard progression of WSSV disease.

“…Some of medicinal herbs and their mixture in diets induced higher growth performance than the fish fed the control diet. In greasy grouper Epinephelus tauvina and shrimp Penaes indicus (Immanuel, Vicncybai, Sivaram, Palavesam, & Marian, 2004), herbs in diets promoted growth and feed efficiency. In current study, the highest weight gain, the specific growth rate was recorded on treatment group fed with a mixture of these three herbs adjuvant (P<0.05).…”

The present study was aimed at determining the effects of medicinal herbs adjuvants on growth, hematoebiochemical parameters, some non-specific immunity and disease resistance to Photobacterium damselae in Sobaity sea bream (Sparidentex hasta). The fish (mean body weight 3.08±0.31 g) were fed fishmeal diets supplemented with either 1% of Garlic (Allium sativum), 1% supplemented of Ginger (Zingiber officinale), 1% supplemented of thyme (Thymus vulgaris), a mixture of these herbs (1% Garlic + 1% Ginger + 1% thyme), and control diet without medicinal herbs, for 8 weeks. The highest weight gains (WG %) and the specific growth rate (SGR) were in fish that fed diets with the mixture of three medicinal herbs (P<0.05). The number of WBC and RBC showed a significant increase in ginger and the mixture of three medicinal herbs compared to the control (P<0.05). The highest total protein and the lowest cholesterol levels were observed in treated groups with ginger diet (P<0.05). The highest albumin and the lowest triglyceride levels were achieved in mixture of these three herbsgroup. The analysis of AST and ALT were significantly decreased in the mixture of these three herbs and ginger groups (P<0.05). The lowest ALP level were showed in mixture of these three herbs group. Furthermore, serum lysozyme activity, total immunoglobulin (Ig) and complement activity (ACH50) were significantly increased in the mixture of three medicinal herbs fed fish and ginger groups (P<0.05). After feeding experiment, fish were infected with Photobacterium damselae strain FN1 and mortalities were recorded. The results of this study demonstrated that dietary mixture of three medicinal herbs and ginger groups could be an improvement in the growth and some non-specific immunity of Sobaity sea bream fry.

“…These chemical residues can then pose risk to the animal and human health [6]. In addition, it was reported that some Vibrio pathogenic strains, including Vibrio harveyi, Vibrio parahaemolyticus and Vibrio splendidus, are resistant to several antibiotics in common use [7]. This has led to a growing need for new antibacterial substances that can be effective in veterinary medicine and characterized by limited undesirable side effects [8].…”

Antibacterial activity of marine macroalgae against fish pathogenic Vibrio species

In mariculture, diseases of microbial origin can cause significant economic losses worldwide; the evolution of microorganism resistance to antibiotics has resulted in a growing need for new antibacterial compounds that are effective in veterinary medicine and characterized by limited undesirable side effects. Increased attention has recently been turned to seaweeds as a promising source for metabolites with antimicrobial activity. Vibriosis is a common disease, caused by bacteria of the genus Vibrio, that can result in high mortality in aquaculture. The aim of this study was to identify seaweeds with antibacterial activity against some pathogenic Vibrio species, in order to identify a possible alternative to the commonly used antibiotics in aquaculture. Chloroform/methanol lipidic extracts of six seaweed species (Chaetomorpha linum, Cladophora rupestris, Gracilaria dura, Gracilaria gracilis, Gracilariopsis longissima, Ulva prolifera) were tested for their antibacterial activities against six fish pathogenic Vibrio species using the disc diffusion method. Different susceptibilities to lipidic algal extracts were observed. All six of the seaweed extracts tested demonstrated inhibition of Vibrio ordalii. The best was that from Gracilariopsis longissima, showing activity against Vibrio ordalii, Vibrio salmonicida, Vibrio alginolyticus and Vibrio vulnificus. The results confirmed the potential use of seaweed extracts as a source of antibacterial compounds or as a health-promoting feed for aquaculture.
