Example 4
As shown in figure 1-2, a culture pond for hybrid scallops comprises a pond body 1, two groups of cross braces 2 are arranged at the upper end of the pond body 1 at equal intervals, installation rods 3 are fixedly arranged at the lower ends of the two groups of cross braces 2, a hanging basket 6 is fixedly arranged at the lower ends of the two groups of installation rods 3, an attachment rope 10 is spirally wound on the circumferential outer surface of the hanging basket 6, the attachment rope 10 is fixedly connected with the circumferential outer surface of the hanging basket 6, an installation seat 7 is fixedly arranged on the inner bottom end outer surface of the pond body 1, an electric heating wire 8 is fixedly arranged at the upper end of the installation seat 7, a first water pump 4 and a second water pump 5 are respectively and fixedly arranged on the outer surfaces of the two sides of the pond body 1, the upper ends of the first water pump 4 and the second water pump 5 are respectively communicated and connected with a water outlet pipe, the lower ends of the first water pump 4 and the second water pump 5 are respectively communicated and connected with a water pumping pipe, one end of the water outlet pipe is arranged at the upper end of the pond body 1, one end of the water pumping pipe is arranged at the lower end of the pond body 1, the front end surface fixed mounting of cell body 1 has the controller, and electric heating wire 8, a water pump 4 and No. two water pump 5's input all with the output electric connection of controller, the lower extreme inner wall that is close to cell body 1 is provided with filter plate 9, the lower extreme of cell body 1 is provided with the drain pipe, and the drain pipe is located one side of drinking-water pipe.
By adopting the technical scheme: when the parent shellfish ripens and heats the temperature of the internal water, the controller is controlled to enable the electric heating wire 8 to heat up by 0.5 ℃ every time, the first water pump 4 and the second water pump 5 are controlled to pump water after the bottom end is heated simultaneously and transmit the water to the upper end of the culture pond, internal water circulation is formed, uniform rising of the internal water temperature is achieved more quickly, when the larva cloth pond controls the water temperature, the controller is controlled to enable the electric heating wire 8 to heat up by 1 ℃ every time, the first water pump 4 and the second water pump 5 are controlled to pump water after the bottom end is heated simultaneously and transmit the water to the upper end of the culture pond, internal water circulation is formed, uniform rising of the internal water temperature is achieved more quickly, compared with a traditional boiler warming method, the temperature rising is more uniform, the warming precision is more accurate, and the influence on the ripening of the parent shellfish and larva growth caused by higher temperature rising is avoided.
FIG. 4 is a comparison result of the temperature rise inside the culture pond and the traditional boiler method for ripening parent scallops in example 1, and it can be seen from FIG. 4 that both the temperature rise inside the culture pond and the traditional boiler method for ripening parent scallops can promote ripening of parent scallops, and when 11 ten thousand cells/ml is reached, the food intake tends to be stable, but the traditional boiler method for temperature rise has a large influence on the food intake of parent scallops, and the temperature rise inside the culture pond can effectively reduce the spawning time.
Fig. 5 is the contrast result of interior intensification of culture pond and traditional boiler method intensification to larva cultivation in embodiment 2, can see by fig. 5, the larva cultivation can be influenced with traditional boiler method intensification homoenergetic to the inside intensification of culture pond, through what the temperature direct influence is the food intake of larva, and then the indirect influence is the survival rate of larva, though different intensification methods homoenergetic heats inside water temperature, but can observe through the food intake, traditional boiler method intensification is great to parent shellfish feeding influence.
Can know by experimental data in figure 4 and figure 5, heat up because of traditional boiler method intensification can't be even to the temperature, control the controller and make 8 constant values that heat up of electric heating wire, and control water pump 4 and No. two water pump 5 simultaneously to the water after the bottom heating the upper end that pumps water and transmit to the culture pond, form inside hydrologic cycle, the even rising of inside temperature of faster realization, it is more even to compare traditional boiler method of raising the temperature, the precision of rising the temperature is more accurate, avoid the higher influence that leads to the fact to parent's shellfish to ripen and larva to grow of temperature rising.
Table 1 shows the comparison results of the conventional raft culture and the culture pond culture in example 3:
| cultivation mode | Survival rate | |
| Buoyant raft culture | Stocking in different places | 87% |
| Culture pond culture | Culturing in the same culture pond | 92% |
TABLE 1
Known by table 1, all set up hanging flower basket 6 and attached rope 10 inside the culture pond, same culture pond is bred, can realize forcing maturity and the adnexed growth of larva to the temporary rearing of parent shellfish through same culture pond, avoids middle unnecessary transportation step, improves the survival rate of larva, and is the same with parent shellfish growing environment simultaneously, avoids the influence that environmental factor caused, compares traditional allopatric hybridization allopatric stocking survival rate higher.
