Embodiment 1

[0023] A method for cultivating summer flower seedlings of yellow catfish mainly comprises the following steps:

[0024] (1) Cultivation pond selection Yellow catfish summer flower seed cultivation ponds can be selected in various ways such as cages and cement ponds. The selected area for this implementation is 15m 2 The concrete pool has a water depth of 0.7-0.9m and is easy to drain. A 40-mesh nylon gauze net cover is installed at the water outlet to prevent fry from escaping. The bottom of the pool has a slope of 1-2%, which is mainly for collecting seedlings.

[0025] (2) Water source selection The water source for cultivation is good, sufficient, and free from toxic substance pollution, and after 2 to 3 days of purification through the reservoir, it is pumped into the water tower for standby. When pumping into the water tower, use 40-mesh nylon at the outlet. The gauze tulle bag filters to keep other harmful organisms out.

[0026] (3) Cultivation pool preparation One w...

Abstract

The invention relates to a cultivation method for the summer fingerling of the pelteobagrus. The method comprises the following steps of: (1) selecting a cultivation pond; (2) selecting a water source; (3) preparing the cultivation pond; (4) reasonably stocking; (5) managing the feeding; (6) managing the quality of the water; and (7) preventing and curing the disease and the like. When the method is used for cultivating the summer fingerling of the pelteobagrus, the total artificial forage domestication technologies with different types and different modes are adopted at different times by means of combining with the mode such as eel material slurry sprinkling, dried power sprinkling, bean blocking by powder cluster and the like according to the biologic learnability in different periods to provide a most effective practical measure and method for cultivating the summer fingerling of the pelteobagrus so as to perfect the cultivation technology for the summer fingerling of the pelteobagrus, firstly and successfully break through the key point of the total artificial forage cultivation of the summer fingerling of the pelteobagrus in the domestics, have a theoretical significance and a practice guidance significance for cultivating the artificial forage of the pelteobagrus and improving the forage use ratio, and lay a technical foundation for cultivating the fingerling on a large scale.

Description

technical field [0001] The invention relates to a method for cultivating fish, in particular to a method for cultivating summer flower seedlings of yellow catfish. Background technique [0002] Yellow catfish [Pseudobagrus fulvidraco (Richardson)] is commonly known as ounce fish, cattle fish, yellow curdfish, etc., and belongs to Siluriformes, Paleidae, and Pseudobagrus genus. It is widely distributed in rivers and lakes in my country. It has strong adaptability and is a bottom-dwelling carnivorous small economic fish in natural water bodies. Because of its tender meat, delicious taste, and no intermuscular thorns, it not only has high nutritional value, but also has medicinal functions such as anti-inflammatory and analgesic. However, due to the low reproductive rate of this fish in natural waters, slow growth, high fishing intensity and various factors, the natural resources are declining day by day. It is increasingly unable to meet the needs of the market. [0003] In ...
