Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for mixed cultivation of D. square snails and snails to solve the problems of long breeding cycle, low efficiency and low water quality and bottom quality in the cultivation process of snails. Deterioration brings problems such as slow growth rate and low breeding success rate. The ecological adaptability of the two is mutually beneficial and complementary to improve breeding efficiency.

Embodiment 1

[0017] 1. Build a pond: choose a hard-bottomed cement pond with an area of ​​3 acres and a depth of 1m. There is an inlet and outlet. The water inlet is set with a 40-mesh net to filter seawater. Add granular zeolite and ceramsite with 4%-8% of sand weight to sand or sea sand, divide the sand into ridges with a width of about 2m, leave 30cm gaps between the ridges as pedestrian passages, and use dirty water quickly when people walk and clean the sand surface flow away;

[0018] 2. Pre-cultivation treatment: Disinfect pond water with quicklime before putting seedlings. The water depth is about 5cm. Plow the surface of the sand once to mix the feed with the sand evenly, increase the fertility of the sand, prepare an appropriate nutrient source for the seedlings of the square starworm, store 50cm of water and wait for the seedlings to be released;

[0019] 3. Stocking of seedlings: Stocking 3cm healthy square starworm medium-cultured seedlings in spring in March, that is, seedli...

Embodiment 2

[0024] 1. Build a pond: select a hard-bottomed cement pond with an area of ​​5 acres, and configure an impeller aerator for every 5 acres, with a depth of 1.5m, with inlet and outlet outlets, and a 40-mesh mesh at the inlet to filter seawater, and a 25cm-thick pond bottom , the river sand or sea sand with a particle size of 3.0mm is divided into ridges with a width of about 2m, and a 40cm gap is left between the ridges as a pedestrian passage for the rapid flow of dirty water when people walk and clean the sand surface;

[0025]2. Pre-cultivation treatment: Disinfect pond water with quicklime before putting seedlings. The water depth is about 10 cm, and the dosage is 120 kg per mu. After standing for 3 days, drain the water and expose to the sun for 7 days; sow commercially available prawn compound feed at 50 kg / mu. Plow the surface of the sand once to mix the feed with the sand evenly, increase the fertility of the sand, prepare an appropriate nutrient source for the seedlings...

Abstract

The invention discloses a method for mixed breeding of Sipunculus nudus and Babylonia areolata. At present, Sipunculus nudus breeding is mudflat breeding without feed, suitable mudflats are limited, and the breeding period is as long as 1.5 years. Bait of Babylonia areolata generally comprises chilled trash fishes, residual bait, residues and metabolic waste, water quality decays easily, and large-scale breeding benefit is not high. Through measures including pond construction, breeding pretreatment, seedling breeding, bait feeding, water quality regulation and disease control, complementary mixed breeding of Sipunculus nudus and Babylonia areolata is realized, and the problem that substrate deterioration caused by high-density breeding and bait feeding in the Babylonia areolata breeding process is solved. The Sipunculus nudus ingests various residues produced after decomposition of residual bait, and the growth speed is greatly increased compared with that through sea area natural extensive breeding. With the adoption of the method, the breeding environment of the Babylonia areolata is improved, the breeding survival rate and quality are improved, the breeding period of the Sipunculus nudus is shortened, the breeding space is saved, and the breeding benefit is increased.

Description

technical field [0001] The invention relates to a method for mixed culturing of the square star worm and the square spot snail, and belongs to the technical field of marine culture. Background technique [0002] Checkered Starworm ( Sipunculus nudus ), commonly known as "sand worms", mainly burrow in intertidal tidal flats with sandy or sandy muddy bottoms along the coast, and mainly feed on organic debris, microorganisms, and benthic diatoms in muddy sandy bottoms. Sandworm has high nutritional value and is known as "natural monosodium glutamate". The dried sandworm tastes delicious but is expensive. Due to the ecological breeding of the square starworm, the cost is only the cost of seedlings and excavation. It has the advantages of small profits, stable production, and convenient management. At present, the sandworm breeding method is mainly stocking in tidal flats, and no feed is generally fed during the breeding process. However, there are limited tidal flats suitable ...
