Embodiment 1

[0032] Such as Figure 1~3 Shown, a kind of device that is used for the artificial rapid mating of mud crab of pseudo cave, comprises cultured glass tank 1, sump 2, circulation pipe 3, water pump 4 and is used to place the stainless steel support 21 of sump 2 (only shows in the figure Its partial structure), the specification of described cultivating glass jar 1 is 100cm * 100cm * 100cm, and the surrounding side wall of described cultivating glass jar 1 is sealed with black plastic film (not shown in the figure), avoids glare. 2-3 plastic sand baskets 5 filled with fine sand are evenly placed on the bottom of the culture glass jar 1, and as mating places, the size of the plastic sand baskets 5 is 15cm×30cm×10cm. The sump 2 is located above the cultured glass jar 1, and the bottom of the sump 2 is equipped with a water pipe 6, the bottom opening of the water pipe 6 faces in the cultured glass jar 1, and the bottom opening of the water pipe 6 is The place is 5~10cm from the bot...

Embodiment 2

[0038] The method for using the device for the artificial rapid mating of the pseudocave blue crab of embodiment 1 comprises the following steps:

[0039] (1) Pretreatment: Install the device according to the structure of Example 1, and then place 2 to 3 plastic sand baskets in the breeding glass tank as a mating place. After the whole device is sterilized, inject clean seawater into the breeding glass tank (salinity is 15~18‰), make the water level height of aquaculture water body be 30cm, adopt black plastic film to cover the sidewall around the aquaculture glass tank, keep darker light, leave the top to be convenient to observe.

[0040] (2) Selection of parents of candidate female crabs: wild blue crabs near Xiaohaihai District, Wanning City, Hainan Province were used as candidate parents, and healthy double-valve female crabs with a weight of 150-250 g were selected as candidate parents. Put 2~5 double-valve female crabs into each breeding glass tank for cultivation. The...

Abstract

The invention discloses a device for artificial rapid mating of scylla paramamosain, which comprises an aquaculture glass tank, a catchment tank, a circulating pipe, a water pump and a stainless steelsupport for placing the catchment tank. The catchment tank is located above the aquaculture glass tank, the bottom of the catchment tank is provided with a water flow pipe, and an opening at the bottom of the water flow pipe faces the inside of the aquaculture glass tank; the bottom end of the circulating pipe is connected with the water pump located in the aquaculture glass tank, and the top ofthe circulating pipe extends to the upper part of the catchment tank; a stone layer is laid at the bottom of the catchment tank, sand bags are laid at the upper part of the stone layer, an activated carbon layer is laid at the upper parts of the sand bags, and filter biochemical cotton is laid at the upper part of the activated carbon layer. Through the use of the device, the pair mating process of the scylla paramamosain is efficient, fast, stable and controllable, the mating efficiency of the scylla paramamosain is improved, the workload of the staff is reduced, and the condition that the scylla paramamosain is susceptible to pathogenic bacteria in the mating process is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a device for rapid artificial mating of blue crabs and a method for using the same. Background technique [0002] Scylla paramamosain, belonging to Crustacea, Decapoda, and Portunidae, is a kind of euryhaline crab, mainly distributed in Zhejiang, Fujian, Taiwan, Guangdong, and Guangxi in my country. and coastal waters of Hainan. Pseudomonas blue crab has the characteristics of fast growth, strong body, delicious meat, etc., and is deeply loved by consumers. In recent years, the output of blue crab farming in my country has increased year by year, maintaining a stable development momentum, and has broad prospects for farming applications. With the development of the consumer market and the expansion of the breeding industry, the supply of blue crab seedlings exceeds the demand, and the contradiction between the shortage of seedlings and the scale of breeding has become increa...
