Bream superior production method

Abstract

The invention discloses a bream superior production method. The method comprises the steps that S1, a field is selected to construct a pond, and water introducing and culturing are conducted; S2, fingerling culturing and pre-stocking are conducted; S3, fry stocking and feed management are conducted; S4, harvesting is conducted. According to the method, a dual-wave radiation method is adopted to irradiate bream fertilized eggs to activate the activity of the fertilized eggs, the hatching successful rate of spawns and the survival rate of young fish are enhanced, the capability of absorbing nutritious ingredients in an environmental water body of young bream fry is enhanced, and a foundation is provided for subsequent healthy developing; fry grow promoting liquid enriched with multiple kindsof traditional Chinese herbal medicine active ingredients is applied to allow the water body environment to be more suitable for the growing and developing of bream fry, and the disease resisting performance of the bream fry is further enhanced; by combining feeding feed conforming to different growing developing stages of the bream and fully achieving the effects of the feed with different ingredients in all growing periods of the bream, the purposes of growing promoting, lengthening and weight gaining are achieved.

Description

technical field [0001] The invention relates to the field of marine aquaculture, in particular to a method for cultivating sea bream with high yield. Background technique [0002] snapper( pagrosomus major ) belongs to the fish class, bream family, also known as red sea bream, Jiaji fish, red Jiaji, copper basin fish, big head fish, small red scales, Jiala, red crucian carp, red plate, red snapper, etc. The body is tall and flat, more than 50cm long, the whole body is silvery red, with light blue spots, the rear part of the caudal fin is greenish black, the head is large, the mouth is small, the front part of the upper and lower jaw teeth is conical, the rear part is white, and the body is covered with ctenoid scales , dorsal and anal fins with spines. Snapper is one of the most important farmed marine fish species in China and is widely farmed in the coastal areas of the Pacific and Indian Oceans. It is produced on average in China's coastal areas. In 2016, the sea bream...

Problems solved by technology

[0005] Relevant studies have shown that ultrasound has special biomedical effects at an appropriate frequency, which can promote the hatching of fish eggs, the growth of seedlings, and improve their feeding and digestion capabilities; TDP radiation is a silicate composite material containing a variety of trace elements. Heat shock radiation, TDP radiometer has a spectral range of 0.55-50 microns, which mainly plays the role of anti-inflammation, analgesia, regulation of metabolism and promotion of biological growth, development, reproduction, and repair of injured parts of animals. It is related to freshwater fish eggs Research on hatching is still rarely seen in public reports, and research on hatching and promoting growth of marine fish eggs has not been found.
