The invention provides a feed additive, feed and preparation method thereof for preventing nutritional fatty liver of fish. Optimized compound of choline chloride, bile acid, carnitine, betaine and phospholipids is added into pellet feed for feeding fish, which can obviously reduce the settlement of fat in liver of fish caused by nutrient induction, avoid the generation of fatty liver diseases and promote the healthy growth of fish.

The invention discloses a traditional Chinese medicine preparation used for preventing fish anorexia. The preparation is prepared by using natural Chinese herbal medicine raw materials. With the preparation, digestion-promoting medicine components in feedstuffs are improved, such that fish digestion and absorption functions are promoted, and fish anorexia problem is solved. The preparation adopts, as traditional Chinese medicine effective components, eight Chinese herbal medicines, which are reed rhizome powder, ginger juice, Mongolian milkvetch root powder, indigowoad root powder, rhubarb powder, argy wormwood leaf powder, Asiatic plantain herb powder, and hawthorn fruit powder. With the synergetic effect of the Chinese herbal medicine components, fish digestion ability can be improved, feedstuff absorption of fish can be improved, fish appetite is enhanced, anorexia phenomenon is reduced, and fish healthy growth is promoted. The traditional Chinese medicine preparation is added into the feedstuff with a proportion of 5%, such that the feedstuff has the advantages of fragrant smell, good palatability, easy digestion, and fast absorption. With the feedstuff, anorexia phenomenon is reduced, fish can grow healthily, fish disease resistance is high, and breeding survival rate is high. The preparation provided by the invention has the advantages of wide raw material source, simple and feasible operation, reasonable formulation, and low cost.

The invention discloses an intelligent sensing aquatic system. The aquatic system comprises a light sensing scanning module, a center control module and an action inducing module. The light sensing scanning module is used for detecting the approaching of an object, and notifies the center control module when detecting that the object is approaching; the center control module is used for controlling the action inducing module to send a signal for guiding the aquatic animals to gather when receiving the notification of the light sensing scanning module; and the action inducing module is used for sending the signal for guiding the aquatic animals to gather under the control of the center control module. Man-machine interaction behaviors related to the technical scheme in the invention enable an aquarium body to be able to carry out feeding simulation and smell generation to induce the aquatic animals to gather, thereby, on one hand, preventing influence of the actual feeding behavior on fish health and aquarium environment, and on the other hand, increasing the joy of life through the intelligent interactive experience.

The invention discloses a large yellow croaker interleukin-1beta (IL-1beta) gene and a cloning method thereof, wherein the large yellow croaker interleukin-1beta (IL-1beta) gene contains a base sequence shown as SEQ ID NO.1 and an amino acid sequence shown by SEQ ID NO.2. The large yellow croaker interleukin-1beta (IL-1beta) gene and the cloning method thereof, disclosed by the invention, have good application prospect in large yellow croaker disease prevention and further development of medical products, and foundation is laid for breeding for disease resistance in large yellow croaker molecular marker aided selection and detecting health state of fishes.
