Problems solved by technology

[0003] Usually, the method of cultivating seedlings of Cadenia prawns is to directly put the parents of Cadenia prawns into ponds to raise seedlings. The parents of Cadenia prawns are very easy to die during transportation, and the parents that are transported back are directly put into ponds and are easy to die, which seriously increases the cost of raising seedlings; Because some white shrimp broodstock do not die after laying eggs, and some will wait until the next breeding season to lay eggs again, this part of the broodstock will inevitably eat a large number of newly hatched white shrimp larvae, thereby reducing the hatching survival rate; It is difficult to control harmful organisms such as dragonfly larvae, and the newly hatched white shrimp larvae are weak in avoiding enemies and are easy to be preyed on, which reduces the survival rate of hatching; Too much will damage the water quality and indirectly lead to the death of shrimp seedlings, and too little will directly lead to the death of some shrimp seedlings
Due to the existence of the above-mentioned defects, the cost of raising seedlings in ponds of Xiuli white shrimp is high and the efficiency is low

Embodiment Construction

[0021] A kind of industrialized seedling raising technology of Cadenia prawn, comprising the following steps:

[0022] (1) Nursery pool preparation:

[0023] The nursery pool is composed of a plurality of rectangular boxes made of fiberglass, about 1 meter in height and 6-9 cubic meters in volume, placed in a room or a greenhouse with adjustable light. Each nursery pool is equipped with power, heating, water inlet and drainage equipment, and is equipped with a microporous aeration device at the bottom;

[0024] (2) Preparation of seedling water:

[0025] The water for seedlings is filtered through three stages. The river water or lake water first enters the reservoir with biological brush for sedimentation and purification, and then is filtered through the sand and gravel channel before entering the secondary pool. The water in the secondary pool is disinfected with chlorine preparations, and then filtered with 350 mesh silk. ; After the water enters the nursery...

Abstract

The invention discloses a batch production fry rearing technique for exopalaemon modestus, which comprises several steps of a fry rearing pond preparation, fry rearing water preparation, a hatchery pond preparation, hatching water preparation, shrimp eggs hatching and fry rearing; the technique is an advanced production way for batch producing high-quality fries by adopting scientific and automatic technical measures and methods. Compared with a traditional fry rearing way, the technique provided by the invention occupies smaller floor area, saves the use amount of parent strains of the exopalaemon modestus, saves fry rearing time, and can be managed visually, further can reduce the cost and increase the production efficiency.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for raising seedlings of Cadenia prawns in an artificial environment. Background technique [0002] Beauty White Shrimp ( Exopalaemon modestus ) belongs to the class Crustacea, Decapod order, Crabidae, and Shrimp genus, and is widely distributed in freshwater lakes and rivers in my country, both in the north and the south. Among the shrimp species in Taihu Lake, Xiuli white shrimp accounts for more than 50%. As one of the main economic catch objects of Taihu Lake "Three Whites of Taihu Lake", Xiuli white shrimp occupies a very important position in the fishery of Taihu Lake in terms of output and output value. In recent years, on the one hand, with the continuous development of industries around Taihu Lake and the continuous increase of population, the water pollution problem of Taihu Lake has become increasingly serious, and the reproduction and survival of the ...
