Problems solved by technology

However, due to the large differences in the newly hatched individual body size and larval nutritional requirements of the spot basket fish, the yellow spot basket fish, and the brown basket fish, it is impossible to use a similar method. It is best to write down the problems caused by such a method

Embodiment 1

[0031] Embodiment 1 A kind of method of pointing basket fish fry breeding

[0032] (1) Emergence of fish fry in ponds:

[0033] In April 2014, the basketfish spawned naturally. After the fry hatched and emerged from the film, they carried out pre-cultivation of the fry in an outdoor pond. The bait transformation began on the 19th day after the film emerged (that is, the bait transformation began 6 days before the emergence of the net). When the fish body size is about 1.2cm. When feeding, evenly sprinkle human eel powder (Jianma brand eel compound feed young eel) into the cultivation pond. The biological bait feeding amount is 80% of the fish body weight on the 19th day after the film is released, and then reduce the feeding amount of the previous day by 20% every day. % of biological bait feeding amount, eel meal can be fed all day from the 19th day to the 24th day after filming, and eel meal is sprinkled at 6:00, 12:00 and 18:00 every day, and each feeding accounts for 33....

Abstract

The invention relates to a siganus guttatus fry breeding method, and belongs to the field of siganus guttatus breeding. The siganus guttatus fry breeding method comprises the following steps: pond cultivation of fry, transportation of fry, preparation of a standard coarse pond and workshop standard coarse cultivation of fry. The siganus guttatus fry breeding method has the technical advantages that the pond fry cultivation time is shortened, the outdoor pond utilization rate is increased, the feeding of biological baits is decreased, the feeding of the artificial mixed feeds is advanced, the cultivation cost is reduced and the fry after indoor standard coarse is ordered, rapid in growth, strong in anti-stress capacity and high in survival rate. The siganus guttatus fry breeding method is mature in technology, safe and easy to grasp, can be rapidly mastered and grasped by the farmers, is suitable for carrying out large-scale artificial breeding of fry and is hopeful for promoting the healthy and rapid development of the artificial breeding work of siganus guttatus fry in China.

Description

technical field [0001] The invention belongs to the field of fish breeding, and in particular relates to a method for raising fish fry. Background technique [0002] Siganus guttatus (Siganus guttatus, commonly known as golden tiger spot) belongs to Perciformes, Basketfish family, and Basketfish genus. Its meat is delicious, high in protein, rich in n-3 highly unsaturated fatty acids, and has high nutritional value. Consumers love it. Omnivorous fish has the characteristics of omnivorous, wide-salinity, and wide-temperature. It feeds on macroalgae under natural conditions. It is also a rare omnivorous fish in marine culture species, which meets the needs of the development of my country's current healthy farming model. . Basket fish, as an excellent new breeding object, has broad prospects for development and utilization. [0003] The spawning period of the bluefish is from April to July every year, and it spawns on the seventh to ninth day of the lunar calendar every mont...
