313 results about "Grouper" patented technology

Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes. Not all serranids are called groupers; the family also includes the sea basses. The common name grouper is usually given to fish in one of two large genera: Epinephelus and Mycteroperca. In addition, the species classified in the small genera Anyperidon, Cromileptes, Dermatolepis, Gracila, Saloptia, and Triso are also called groupers. Fish in the genus Plectropomus are referred to as coralgroupers. These genera are all classified in the subfamily Epiphelinae. However, some of the hamlets (genus Alphestes), the hinds (genus Cephalopholis), the lyretails (genus Variola) and some other small genera (Gonioplectrus, Niphon, Paranthias) are also in this subfamily, and occasional species in other serranid genera have common names involving the word "grouper". Nonetheless, the word "grouper" on its own is usually taken as meaning the subfamily Epinephelinae.

Healthy and efficient method for cultivating giant groupers by deepwater anti-stormy waves cages

The invention discloses a healthy and efficient method for cultivating giant groupers by deepwater anti-stormy waves cages, which comprises the following steps: (1) selection of a cultivating sea area: the cultivating sea area is an opening sea area with reef island shields, smaller stormy waves, more smooth tide and above 15m of depth of water; (2) requirements of cage facilities: the cages have the capability of fighting against 12-level typhoon and the rough sea with a height of above 5 cm; (3) selection and stocking of the giant grouper fries: injury-free giant grouper fries with robust physique and consistent specifications are selected and then soaked and sterilized by fresh water before being fed; (4) feeding technique: after being hungered for 2 days, the giant grouper fries are recovered to feed for 2 days with the baits of iced and fresh trash fishes, and controlled to keep eight full at every time, and 0.1 to 0.3% of amino electrolytic polyvitamines and 0.02 to 0.04% of garlicin are added based on the weight of the baits in the baits; and (5) feeding and management. The method has the characteristics of being simple to cultivate and operate and less in bait investment, and the obtained nuisanceless cultivating giant groupers have the characteristics of high yield, good quality, low bait coefficient, high survival rate and fast growth speed and the like.

DNA (Deoxyribose Nucleic Acid) aptamer for detecting grouper iridovirus infection, as well as screening method and application of DNA aptamer

The invention discloses a DNA (Deoxyribose Nucleic Acid) aptamer for detecting grouper iridovirus infection, as well as a screening method and an application of the DNA aptamer. Two inverse screening steps are introduced in each screening process; first, a single-stranded DNA library of the former screening process is bound with normal cells to remove nonspecific ssDNA (single-stranded DNA) bound with the normal cells of a grouper; then, supernatant is bound with grouper iridovirus infected cells for screening; and ssDNA separated from the grouper iridovirus infected cells is bound with the normal cells for separation to obtain the supernatant. A PCR (Polymerase Chain Reaction) amplification library prepares the single-stranded DNA library. The above screening flow is repeated; compared with the number of the normal cells in the first screening process, the number of the normal cells in the screening process is increased by 2-6 times; compared with binding time of the library and the cells in the first screening process, the binding time of the library and the cells in the subsequent screening process is increased to 1h from 0.5h; and the binding time of the library and the virus infected cells is shortened to 0.5h from 1h to improve the screening efficiency of each process.

Artificial propagation method for yellowfin groupers

The invention provides an artificial propagation method for yellowfin groupers. The artificial propagation method comprises the steps that (1) parents are selected; (2) a parent breeding pond is separated into a deep water area and a shallow water area with water flow communicated, wherein the water depth of the deep water area ranges from 4 m to 5.5 m, and the water depth of the shallow water area ranges from 3 m to 3.5 m; (3) parent fish breeding management is carried out, wherein a, in first 3 weeks during breeding, LED green light and yellow light alternately irradiate the water surface ofthe pond, and after the parent fishes are bred for 3 weeks or longer, the water surface of the pond is irradiated by the LED green light; b, feed is prepared from 3-5 parts of grouper compound feed and 1-2 parts of small fish and shrimp and artificial pellet feed, the parent fishes are fed with the first feed in the first 3 weeks during breeding, and the parent fishes are fed with the second feedafter being bred for 3 weeks or longer; c, the water temperature of the pond ranges from 21 DEG C to 26 DEG C, and water dissolved oxygen is larger than 4.8 mg/L; (4) breeding is enhanced before propagation is carried out; (5) artificial propagation is carried out; (6) zygotes are collected and hatched. According to the artificial propagation method for the yellowfin groupers, the adaptive capacity to environment of the parent fishes is enhanced, the activities of fish shoals are effectively promoted, the feeding rate is effectively increased, the fertility is high, and large-scale artificialbreeding of the yellowfin groupers can be effectively achieved.
