The application discloses a self-adaptive multi-frequency band bionic vibration snake and insect expelling device and method, and belongs to the technical field of outdoor protection equipment. The device comprises a tool carrier, a bionic low-frequency vibration generating module, a main control module, an infrared sensing module and a power supply module, and can be pre-installed or externally mounted. The vibration module is in reliable contact with the ground, thereby ensuring effective vibration conduction. The device outputs adjustable bionic pulse vibration of 15-280 Hz, simulates the ground stepping signal of large terrestrial animals, and realizes targeted repulsion by using the differential vibration sensing characteristics of snakes, insects and mice. The device is provided with three working modes of fishing silence, camping global and strong snake repulsion, and is integrated with functions of starting gradient protection, human body intelligent start and stop, multi-dimensional resistance, ground medium self-adaptation and environmental parameter compensation. The device supports single independent protection and multi-ring networking efficiency, has a protection level of IP67, is suitable for all scenes such as fishing, camping, yard and breeding, and can realize integrated long-acting physical repulsion of snakes, insects and mice.

The application provides alligator feed, an alligator feeding method and application, and relates to the technical field of alligator breeding. The alligator feed with high meat yield rate comprises fish, fish meal, vitamins, calcium powder, medicinal materials and probiotics; the fish meal comprises fish, shrimps and land animal meat; and the medicinal materials comprise at least one of malt, houttuynia cordata and hawthorn. Through the alligator feeding method, the alligator feed is fed, the meat yield rate, the egg production rate of alligators, and the fertilization rate and the hatching rate of alligator eggs are improved, the alligator feeding system has high economic benefits, and the preparation method of the alligator feed is simple and efficient.

The invention discloses a waste fishpond ecological restoration method based on an ecological corridor. The method comprises the following steps: surveying and mapping a waste fishpond; a biological corridor is constructed between the land and the fish pond to ensure the passage of terrestrial animals; an aquatic ecological corridor is constructed between the fishpond and the ocean, and tidal water is introduced to realize periodical fluctuation of the water level of the fishpond; pond ridge removal, slope cutting and tidal creek excavation are conducted on the interior of the fishpond, and a gentle slope area and a water power circulation system which are communicated with the ecological corridor are formed; shrubs are planted in different areas according to the elevation, the function of a fishpond ecosystem is restored, and continuous communication of a land-fishpond-marine ecosystem is achieved by building a biological corridor between a land forest and a waste fishpond and building an aquatic ecological corridor between a sea and the waste fishpond. Terrestrial animals can smoothly enter the mangrove forest restoration area of the fishpond through the biological corridor, and aquatic organisms can freely migrate between the ocean and the fishpond through the aquatic ecological corridor, so that obstruction of the abandoned fishpond to biological migration is effectively eliminated, and regional ecological connectivity is enhanced.

The invention discloses a jellyfish crude polypeptide with tyrosinase inhibitory activity, a jellyfish polypeptide and a preparation method and application thereof, and belongs to the technical field of biology. A jellyfish crude polypeptide is prepared, a jellyfish polypeptide GGDYLSIHMRR is identified and optimized from the jellyfish crude polypeptide, and experiments prove that both the jellyfish crude polypeptide and the jellyfish polypeptide provided by the invention can inhibit tyrosinase activity in vitro, and can inhibit melanin secretion of B16-F10 mouse melanoma cells and inhibit tyrosinase activity in the cells. Therefore, the jellyfish crude polypeptide and the jellyfish polypeptide can be used as a tyrosinase inhibitor and an anti-melanin synthesis agent and are applied to the fields of cosmetics, medical treatment and the like. Experiments prove that the jellyfish crude polypeptide and the jellyfish polypeptide provided by the invention have no cytotoxicity, are derived from oceans, and have no disease risks and religious barriers of terrestrial animals.
