Problems solved by technology

[0004] The technical problem to be solved in the present invention is, aiming at the deficiencies in the prior art, to determine the stage of the best taming artificial buoyant pellet feed for the anchovy, and to propose a method for inducing domestication of high-density cultivation of the anchovy. After the treatment of the pellet feed, it will be fed and domesticated and gradually transitioned to completely ingest the floating pellet feed, and the artificial breeding technology of 3-5cm cuttlefish seedlings will be established, so that the cuttlefish can be converted to artificial floating pellet feed, so as to realize the industry of cuttlefish Chemical farming provides new ideas

Embodiment Construction

[0022] A method for artificially domesticating and eating floating pellet feed of scorpion anchovy, comprising the following steps:

[0023] 1. Determination of the best domestication stage:

[0024] According to the growth and development characteristics of sword anchovy fry, the body length of 3-5cm and weight of 0.4-0.6g after enhanced cultivation by Artemia were selected as the food object. This stage has strong adaptability, sensitivity to light changes, and resistance It has a strong stimulating ability and is the best stage for high-density domestication.

[0025] 2. Select the special pool and cage for domestication:

[0026] Requirements for indoor special pools: round tempered glass pools or rectangular cement pools, with a single pool area of ​​50-100 square meters, a pool depth of 1.5-2.0 meters, equipped with a microporous oxygenation device, the pool water is in a micro-flow state, and the flow rate is 0.1-0.2m 3 / min, transparency 30-40cm, dissolved oxygen ≥ 6...

Abstract

The invention discloses a method for manually domesticating coilia ectenes to eat floating pellet diet. The method includes selecting eating domestication time; setting requirements on an eating domestication tank and a net box and reasonable coilia ectenes eating domestication density; selecting eating domestication feed; performing special processing and flashing induction on the pellet diet. By the method, 15 days are needed to completely domesticate coilia ectenes to eat the floating pellet diet, so that the feed problem of coilia ectenes is solved, and growing speed and yield of the coilia ectenes are increased remarkably; the method is suitable for large-scale farming of coilia ectenes and is of important significance in intensive development of coilia ectenes farming industry.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for taming fish, in particular to a method for artificially taming floating granular feed of the important migratory fish-saury anchovy. Background technique [0002] Yangtze River Anchovy ( Coilia nasus ), belonging to Clupeiformes, Engraulidae, Anchovy ( Coilia ), commonly known as saury, is plump and plump, with delicious meat and is famous for its freshness, tenderness and beauty. In view of the continuous decline of wild cuttlefish resources, since 2003, the Freshwater Fishery Research Center of the Chinese Academy of Fishery Sciences has started to carry out germplasm resource preservation, artificial propagation technology, seedling cultivation technology and ecological breeding of cuttlefish technology research. It pioneered the irrigation technology and anti-stress transportation technology of the Yangtze River Anchovy, which opened a new chapter in artifi...
