Problems solved by technology

Similarly, when phytoplankton blooms, nutrients are consumed, the nutrient content in seawater is reduced, and there is no continuous supplement of nutrients, the production and quantity of shellfish are also affected

Embodiment 1

[0010] Example 1: Under normal conditions, river water entering the sea brings a large amount of nutrient salts and organic matter to shellfish culture waters. The organic matter is decomposed by microorganisms to produce nutrient salts, and phytoplankton in the waters rely on continuous absorption of nutrient salts to grow and reproduce. Provide rich bait for shellfish, but when the rainfall is insufficient, the amount of water flowing into the sea will decrease, the nutrient content in the water area will be low, phytoplankton cannot reproduce, and there will be less plankton in the water area, and the output and quantity of shellfish will be affected. Affected by the impact, the shellfish breeding industry has always been in an unstable state, and cannot get rid of the situation of relying on the weather.

Embodiment 2

[0011] Embodiment 2: the seabed dredger 8 is put into the seabed, and a rope hole 13 of the ship 3 body connects the fixed plate hole 7 on the seabed dredger 8 by the second cable, and the ship 3 is with the seabed dredger 8 on the seabed Suck the ooze through the mud suction pipe 4, and suck the ooze (mainly microbial decomposition) deposited in the seabed to the sea surface to provide bait biological device 20 through the mud suction pipe 4 of the mud pump 2. The mud suction groove 9 prevents water absorption from being too much, and the mud suction is less, and moves with the ship. The middle of the mud groove baffle plate 11 is provided with a bearing 10, and the bearing 10 is connected to the agitator 12. , the phenomenon of less mud suction, there are several measures, the mud pumping pipe 4 constantly sucks the ooze deposited in the seabed to the sea surface to provide bait biological device 20, and after the bait biological device 20 is filled with deposited ooze on the...

Abstract

The invention provides a shallow sea culture method providing food organisms for shellfish growth. With the method, ooze can be cleaned, and seabed ecological environment can be improved. The technical scheme of the method is that the mainly adopted devices are an ooze delivery pipe (1), a slurry pump (2), a ship (3), an ooze pumping pipe (4), a cable (5), a fixing plate (6), a fixing plate hole (7), a submarine ooze absorption device (8), ooze absorption slots (9), a bearing (10), an ooze tank baffle plate (11), a stirrer (12), a rope hole (13), an outer plate (14), floating bodies (15), a towing rope hole (16), a sieving mesh baffle plate (17), simple stirrers (18), drying plates (19), sea surface food organism providing devices (20), a pedestal (21) and an iron anchor (22). With the method provided by the invention, a situation that shellfish culture is dependent on natural environment can be changed. Deposited ooze in the sea area can be effectively utilized, such that ecological environment improvement is realized, and shellfish culture yield increase can be accelerated. The method is a sustainable development method, and is green and environment-friendly. The method is suitable to popularize in the field of shallow sea culture.

Description

technical field [0001] The invention relates to the technical field of shallow sea culture, in particular to a shallow sea culture method for providing bait organisms for the growth of shellfish. Background technique [0002] The shoal shellfish culture is carried out in the shallow sea. The bait of the shellfish is mainly plankton in the sea water. The more plankton, the more the plankton meets the food needs of the shellfish, the faster the shellfish grows, the individual is plump, and the gonads are developed. Either way, if the amount of fecundity is high, the output and quantity of shellfish will increase. On the contrary, the less plankton in seawater can not meet the needs of shellfish for food, the output and quantity of shellfish will decrease. The plankton in the water area is the key to increase the production and income of tidal flat shellfish. Plankton includes phytoplankton and zooplankton. Zooplankton mainly feed on phytoplankton, and the growth and reproduct...
