Generally, the water depth is selected to be 6m or less when the water is in dry tide (the water depth is below 6m when the tide is ebb), the water flow is smooth, the transparency is high, and the hard bottom of the rock reef with flat terrain is used for bottom sowing and propagation.
5. Reef cluster arrangement
As shown in fig. 1, reef arrangement is performed by selecting reef levels with different cross sections of the seabed, a professional diver carries out launching operation, a matrix reef group is built in a mode of putting primary-secondary reefs and living reefs, the growth coverage efficiency of the agaricus in an area range is improved, and therefore a permanent seaweed field is built in a point-area surface mode, and the purpose that seaweed resources in the area range can be self-repaired is achieved.
As shown in fig. 2 and 3, in the present embodiment, the matrix reef cluster is designed as follows:
1) according to the rectangular array design of reef groups, the coverage range of the reef groups and the number of reef group units are designed according to the topographic characteristics of a repair area, the matrix reef groups are established at a relatively flat reef as far as possible, the distance between two adjacent units in the reef groups is preferably 5-10 m, so that the coverage area can be increased, and the effect of repairing the agar resources is improved by using a point-area surface.
2) Reef crowd unit design, the primary and secondary reef mode of constituteing by 1 mother reef unit and 8 son reef units, son reef unit uses mother reef unit to encircle as the center, and the distance of every son reef unit and mother reef unit is about 1.5 ~ 3m, can suitably shorten or increase distance each other according to the quality of terrain condition.
3) The design of the mother reef unit comprises 16 double-layer net cement frames (or 60cm × 60cm cement frames can be selected according to the terrain features) with the specification of 80cm × 80 cm. 4) The design of the sub-reef unit comprises 5 double-layer net cement frames with the specification of 60cm multiplied by 60cm in a mode that vertex angles are connected, and the double-layer net cement frames with the specification of 80cm multiplied by 80cm can be selected at the spacious position of the reef level. The design of the reef units comprehensively considers cost factors, and the algae growth coverage area is increased on the premise of saving the laying quantity.
6. Job resource repair assessment and maintenance
The method comprises the steps of setting an agar-agar remediation demonstration area, periodically monitoring indexes such as growth rate, survival rate and coverage of agar-agar in the core remediation demonstration area, and judging seaweed resource remediation effect and evaluating self-remediation capability of an artificial seaweed field (matrix reef group) by detecting water environment indexes (including nitrogen concentration, phosphorus concentration, suspended matters, transparency, dissolved oxygen and the like) and analyzing biological diversity.
In this embodiment, after the agarophytes field (i.e., the matrix reef cluster) is established, the natural growth conditions of agarophytes are regularly observed, and on the premise that no algae species are supplemented, the amount of agarophytes is increased to a large extent, which indicates that the self-repairing capability is strong.
Aiming at the influence of other seasonal seaweeds caused by ecological niche competition, biological prevention and control technologies are established by bottom sowing sea urchins, sea cucumbers, snails and the like, and the proliferation of the agaric branches is prevented from being limited by nutrition and space competition. By arranging the buoy, the warning board, the media propaganda and the like, the environmental awareness of the public is improved, and the artificial damage caused by trawling operation of the past fishing boat and fishing of surrounding fishermen and other behaviors is avoided.
In summary, the bottom-sowing multiplication method for the agar resource in the embodiment of the invention systematically expounds the whole technical process of the agar resource restoration, and under the situation that the natural resource degradation of macroalgae existing in the global scope at present becomes more serious day by day, the stability of the attachment growth of algae strains can be effectively improved and the probability of the formation of permanent algae fields can be increased by researching and establishing the artificial large-scale bottom-sowing multiplication restoration technology for the agar resource, so that the total amount of the algae resources can be increased, and the purposes of gradually improving the marine ecological environment and restoring the ecological function can be achieved.
