example 1

[0072] Example 1. Aquaculture device

[0073] A square seedling dish made of seawater corrosion-resistant material is made of metal in this embodiment, and the center of the top is depressed to form an aquaculture groove, and the bottom of the aquaculture groove It has a wavy structure. There are four tripods protruding from the bottom of the seedling tray. The side length of the seedling tray is 40 cm, and the height including the tripod is 15 cm. The opposite side walls of the seedling tray are respectively pierced with water inlets and drainage. The horizontal position of the water inlet or outlet is 5 cm higher than the bottom of the seedling tray, and 5 cm away from the closer edge of the side wall where it is located. The water pipe extends upwards from the water inlet at an angle of 15 degrees, and the drainage port is connected with a circular pipe-shaped drainage pipe, and the drainage pipe extends downwards from the drainage port at an angle of 15 degrees; the other ...

[0075] Example 2. Seawater treatment method

[0076] The seawater is pumped into the seawater purification pond, and treated with macroalgae for 2 days (the macroalgae can be asparagus (Gracilaria spp.) of Rhodophyta or Ulva spp. of Chlorophyta) .) etc. Processing capacity: 1 metric ton of seawater per 1 kg of wet weight seaweed every 2 days), and then filter the purified seawater with a filter with a pore size of 5 μm to remove suspended solids and other plankton, The treated seawater is stored in seawater storage tanks.

example 3

[0077] Example 3. Preparation of bait

[0078] Please see Figure 5 As shown, the diatoms (Navicula spp., Nitzschiaspp., Amphora spp., Cocconeis spp.), the initial concentration of diatoms is 5 ~ 7.5*10 4 cells / ml, placed in a 250ml Erlenmeyer flask for 7 days at 25°C, then transferred to a 2-liter Erlenmeyer flask for 7 days at 25°C, then transferred to a 20-liter PC plastic bucket at 25°C Cultivate for 7 days, and then switch to 500 liters of the bait supply tank of the aquaculture assembly of the present invention and cultivate for 7 days at room temperature (not specially adjusted to 25° C.), so that a large number of edible Abalone seedlings can be cultivated in the way of sequential amplification culture. Diatom (final concentration is 130~150*10 4 cells / ml). The culture media in Table 1 were used in the whole culture process of bait diatoms.

Abstract

An aquaculture device, comprising at least one seedling tray, each seedling tray has an aquaculture groove, and the side wall of each seedling tray forms a water inlet and a water outlet connected to the aquaculture space, the bottom of each seedling tray There is a support structure. When the aquaculture device of the present invention includes more than two seedling trays, the seedling trays above are arranged in the aquaculture grooves of the seedling trays below, and the seedling trays are stacked up and down, and the seedling trays The disks can also be connected and arranged in the horizontal direction through the interlocking structures provided therebetween. The seedling trays are independent and not connected to each other, so the infection of diseases can be avoided and the mortality rate can be reduced. The present invention also relates to an aquaculture method, using the above aquaculture device to cultivate aquatic seedlings indoors, and providing purified and filtered seawater and sufficient bait, so the quality of aquatic seedlings can be maintained.

Description

technical field [0001] The invention relates to an aquaculture device, an assembly and a method, in particular to an aquaculture device, an assembly and a method for indoor cultivation to increase the survival rate of aquaculture organisms. Background technique [0002] Aquatic products with economic value, such as abalone, nine-hole, meretrix meretrix, and other shellfish are usually produced artificially to fully supply the market demand. The current aquaculture method is to carry out static culture with seawater, that is, a PVC corrugated board is suspended in a cement pool located outdoors, and then seawater is introduced, thereby generating various microalgae (such as diatoms, etc.) on the surface of the PVC corrugated board. ), and then splash the aquatic seedlings in the cement pool, the aquatic seedlings will attach to the PVC corrugated board, and use the microalgae as nutrients for the growth of aquatic seedlings. [0003] Taking the propagation method of Haliotis...
