The present invention discloses a process of extraction, purification and characterization of a non-polar fluorescent dye from a marine echinoderm Holothuria scabra, compositions containing the dye and various applications of the dye, said dye is a natural, cell permeant, nontoxic and environmentally friendly non-polar fluorescent dye.

Methods for inducing systemic, non-specific and / or sequence specific immune responses in invertebrates, e.g., marine invertebrates such as mollusks, porifera, ctenophora, echinodermas, marine worms, cnideria and preferably crustaceans, by the administration of at least one dsRNA, that confers immunity against a pathogen, or modulates expression of gene that affects growth, reproduction, and general health or “robustness” are provided. Also provided are methods of identifying invertebrate genes, e.g., crustacean genes, the expression of which is involved in the induction of non-specific (systemic) immune responses against pathogens. Also disclosed are preferred delivery systems and methods for stably administering at least one dsRNA to a crustacean whereby the dsRNA is administered via injection, immersion, in a feed or nutrient medium or comprised in a microorganism, e.g., yeast or microalgae, that expresses said dsRNA and is ingestible by said crustacean, e.g., a shrimp.

An Echinozoa tissue or organ extract comprising antioxidant compounds is disclosed. Also disclosed is a process for obtaining an Echinozoa tissue or organ extract, as well an extract obtained by this process. Compositions comprising such an extract are also described. Uses of such extracts / compositions, as well as corresponding methods of treatment, for example as an antioxidant or to decrease or inhibit oxidative stress in a cell, tissue or subject are also described.

The present invention discloses a process of extraction, purification and characterization of a natural eco-friendly nontoxic cell permeant multiple fluorescent protein dye from a non bioluminescent marine echinoderm Holothuria scabra, compositions containing the dye and various applications of the dye.

The invention relates to protection development and effective use of shallow sea within 20 meters in the south China sea including offshore and high seas, and belongs to the technical field of echinoderm aquaculture of farm aquaculture, in particular to a tropic shallow sea Bohadschia argus bottom sowing reproducing method. Bottom sowing of the Bohadschia argusis is performed in a tropic ocean shallow sea area; bottom sowing breeding of the Bohadschia argusis can be performed by using environment resources in the area. The method can protect oceans, can continuously and effectively utilize the oceans, and can be duplicated in tropic ocean wide space.

Devices for guided tissue regeneration (GTR) include a matrix of chitosan and mutable collagenous tissue (MCT) wherein the chitosan is electrostatically bonded to the MCT to form MCT-chitosan composite material. The MCT can be isolated from invertebrate marine organisms, such as sponges, jellyfish, mollusks and echinoderms. The MCT-chitosan composite material can be formulated as a biofilm, a 3D-sponge, a hydrogel, or as an electrospun nanofiber, or the MCT-chitosan composite material can coat a biomaterial surface. The devices can include wound dressings and tissue sponges, including 3D sponges. Applications include tissue engineering and wound healing, as well as burns and other related guided tissue regeneration applications. MCT and MCT-chitosan composite material, contained in a pharmaceutically acceptable topical carrier, also has cosmeceutical applications, for treating scars, as well as skin discoloration and various pigmentation issues, including melasma / chloasma.

The individual marking method of the present invention solves the problem that it is difficult to mark echinoderms in traditional breeding, and can conveniently make individual marks on echinoderms such as sea cucumbers and sea urchins. In addition to monitoring the growth traits of individuals, it can also record Traits that cannot be recorded using traditional fluorescent markers, such as the bait coefficient of individuals, are also cheaper than traditional fluorescent markers, and it is easier to identify selected individuals during seed selection. The emergence of this method makes it possible to breed echinoderms using the BLUP method. Therefore it can be said that it has possessed multiple advantages, and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

The present invention discloses one kind of sea cucumber beer and its preparation process and identifying method, and features that the sea cucumber beer contains the active nutritious components of sea cucumber, including sea cucumber saponin in 10<-5> ppm to 1 %, and that the content of sea cucumber saponin in 0.3-60 ppm can results in excellent foaming performance and foam maintaining time as long as 6 hr. The sea cucumber beer is prepared in the basically same process as common beer, but the addition of water solution, alcohol solution and / or medicinal wine of sea cucumber before or after the fermentation. The water solution, alcohol solution and / or medicinal wine of sea cucumber as the material is identified via diluting for 2-200 with water for foaming identification.

The invention belongs to the technical field of agricultural insect pest control, and specifically relates to a biological control method for the pupal stage of the eucalyptus inchworm, which comprises the following steps: spreading metarhizium anisopliae granules during the pupation stage of the eucalyptus inchworms, the metarhizium anisopliae granules comprising: Metarhizium anisopliae spore powder and nutrients that provide nutrition for Metarhizium anisopliae. The beneficial effects of the present invention are: in the prevention and treatment method of the eucalyptus inchworm pupa stage, Metarhizium anisopliae has strong pathogenicity to Eucalyptus inchworm pupae, and the control effect is good; meanwhile, Metarhizium anisopliae is environmentally friendly, non-toxic and has no residue, and the Metarhizium anisopliae granules The agent contains nutrients, which can realize the continuous proliferation of Metarhizium anisopliae in the environment, maintain the amount of bacteria in the soil, and achieve the purpose of continuous pest control.

The invention provides a method for promoting maturation and artificial fertilization of starfish high-quality eggs, comprising: (1) cultivating starfish parents; (2) collecting starfish male and female gonad tissues; Guanine promotes the ripening of starfish eggs; (4) Artificial fertilization of starfish. The invention establishes the method for obtaining high-quality starfish ovum and artificial fertilization for the first time, and screens out the most suitable maturation-promoting agent and maturation-accelerating time for starfish ova through experiments. The invention has the characteristics of convenient operation, high efficiency and practicability, does not harm parent bodies, and the acquisition of ovum is not restricted by seasons; it has important application value and prospect of popularization and application in the aspects of echinoderm reproductive biology and experimental embryology research.
