Problems solved by technology

However, a special biological bait supply system has not yet been formed, so there is a big gap in the supply of biological live bait, especially in the breeding of fish, shrimp, and crabs that use a large amount of biological live bait. Seedling failure caused by insufficient bait supply or poor bait quality

Embodiment Construction

[0021] In order to make it easier for those skilled in the art to better understand the present invention, specific implementations of the present invention are provided below.

[0022] Indoor cultivation

[0023] Adopt 4 to be 36 meters, be wide to be 30 meters culture ponds, continuously cultivate 14d Mogolia mongolica from initial inoculation 285 / ml, 237 / ml, 185 / ml, 215 / ml respectively reach 5177 / ml, 4147 / ml, 3096 / ml, 3896 / ml. From the 15th day onwards, Mogolia mongolica was harvested with water every day, and the harvested amount was 20-30% of the total water body (Table 1). In order to explore the effect of continuous culture of Mogulia mongolica, 4 animals were cultured continuously in cement ponds for 53-59 days. After nearly 40 harvests, 227.9kg, 172.6kg, 127.4kg, and 165.5kg of Mogulia mongolica were harvested respectively (Table 2). The total production of Mogolia mongolica includes the last total harvested quantity. The average daily production is calculated bas...

Abstract

The invention relates to the field of aquatic baits and discloses an intensive production method for Mongolian Moina. Characteristics of the Mongolian Moina at all stages are known based on the comprehensive study on aspects of the Mongolian Moina, such as reproduction, development, ingestion, growth and the like. The Mongolian Moina is cultivated to achieve the intensive production by using an indoor cement pool and an outdoor pool, and a scientific and feasible practical technology which can also can utilized fully in production is formed, so that the current situation that a biological bait market is in short supply in the area in seedling production currently is alleviated.

Description

technical field [0001] The invention relates to a production method of aquatic bait, in particular to an intensive production method of Mogna mongolica. Background technique [0002] Moina mongolica Daday (Moina mongolica Daday) belongs to Crustacea, Braniopoda, Cladocera, Moina mongolica Daday, and the genus Moina mongolica. Mogolia mongolica is an aquatic planktonic cladocera that feeds on bacteria, organic detritus and single-celled algae. It has rich nutrition, strong reproductive ability, short reproductive cycle, rapid growth, high environmental tolerance, wide temperature and wide salt. The life history of Mogolia mongolica includes two alternate generations, the parthenogenetic generation and the sexual generation. Under suitable conditions, mature daphnia have a lot of eggs, generally up to 20-30, which is suitable for high-density cultivation and is a biological live bait for seawater nursery and aquaculture with great development value. [0003] With the rapid ...
