“…The Ca content in fresh starfish is reported 12.97% by Sorensen (2015) but in our study we have got 9.40%, which might be due to the variation of species, size, season, source, analytical method etc. Moisture content of the starfish A. amurensis was detected as 63.9%, which was slightly lower than the starfish of A. planci with the value of 67.7 to 69.1% by weight (Luo et al, 2011).…”

The starfish Asterias amurensis is one of the common species in Japanese coastal area. The species is considered an extremely rich source of biological active compounds, including saponin. Saponins are secondary metabolites and exhibit a wide spectrum of biological activities. The species of starfish caught in Kobe, Hyogo prefecture, Japan, was analyzed for species identification and micronutrient content. The starfish extract was evaluated for different biological properties and its fractions obtained using thin layer chromatography (TLC). Nucleotide sequence analysis of the 16S rRNA gene fragment of mitochondrial DNA indicated that partial sequences of PCR products of the species was identical with that of A. amurensis. The micronutrient contents results showed that nitrogen (N) content of the starfish was 1.50% of dry weight and the copper content was 2.10 µg/g. The crude extract of A. amurensis exhibited predominant growth inhibitory activity against six human fungal pathogens and also showed hemolytic activity against 2% sheep erythrocyte. The present findings suggest the possible pharmacological applications of A. amurensis that can be used as food ingredients and antifungal component.Key words: Asterias amurensis, crude extract, biological property, saponin, antifungal component. INTRODUCTIONNowadays, invasion of exotic species has become a major concern in the marine environment since the number of human-mediated introduction has increased (Ruiz et al., 2000). Many studies researching marine invertebrates to determine the therapeutic potential of their bioactive materials have been showing very promising results (Lee et al., 2014 (Ishii et al., 2006;Suh et al., 2011). Saponins are a group of natural plant glycosides, characterized by their strong foam-forming properties in aqueous solution that occur in a wide range of plant species (Osbourn, 1996). The presence of saponin has been reported in more than 100 families of plants out of which at least 150 kinds of natural saponins have been found to possess significant anti-cancer properties (Man et al., 2010). Saponins have also been commonly employed in some other sector in medical practice because of their potential health benefits. In addition, many plant saponins have been isolated and they exhibit broad spectrum of biological uses, such as anti-cancer, anti-inflammatory, ion channel blocking, immune stimulating, antifungal, and anti-thrombotic property (Lee et al., 2014;Thao et al., 2014).The starfish A. amurensis, called the northern Pacific starfish, is a predator of the marine benthic system that is listed in the top 100 invasive species globally (Lowe et al., 2000). The species was identified as a serious pest species because of its ability to consume a wide range of food sources including mussels, scallops, and clams (Global invasive species database, 2016). The wastes of them results in serious environmental pollution. Furthermore the large outbreak of starfish causes significant loss of the marine ecosystem and fishing gears (Kim, 1969). There i...

“…241 The quality of protein fraction in starfish meal is comparable to FM. 242 It was documented that the protein-containing liquid part of starfish should be collected and drained rapidly to obtain a high protein level in the starfish meal. Furthermore, starfish meal is interestingly characterised by a better amino acid profile than other plant alternatives.…”

“…Numerous chemical components with antimicrobial, antifungal or antiviral activities found in starfish meal make this alternative feed ingredient suitable for general animal nutrition. 242 Overall, the growth conditions for these NIS are still not defined and more research efforts to increase knowledge on ecology, biology, feeding and reproduction. The collection methods should be optimised and mitigation measures developed to control their invasions should at the same time to make use of their collected biomass in aquafeed.…”

“…Starfish have a crude protein level from around 270-450 and up to 700 g/kg in the dry matter (DM) and a high quality amino acid (AA) profile (Levin et al, 1960;Nørgaard et al, 2015;Sørensen and Nørgaard, 2016). The calcium (Ca) level of above 100 g/kg, however, disturbs the balance between Ca and phosphorus (P) in pig diets.…”

To study the annual variation in the composition of nutrients relevant to pig and poultry feeding, monthly samples of starfish (Asterias Rubens) were taken in Denmark. The effect of different locations and starfish sizes was also assessed. Crude protein (CP) and phosphorus were high from February to May and lower thereafter. The AA profile remained constant and followed the same pattern as CP. An opposite pattern of CP was observed for both ash and calcium. Fat followed no clear annual pattern. Starfish within the smallest size group had the lowest fat and CP levels and the highest ash and calcium levels. The most profound differences between locations were observed in May. The seasonal pattern in chemical composition seemed related to spawning and gonadal developments. Large and medium sized starfish caught between February and May will be most suitable for pig and poultry feed.
