Problems solved by technology

Therefore, the bait problem is the basis of seed breeding, and the planktonic larval stage is an important period for the maintenance of sclerosus mussel seedlings. The problem of basic bait formula during this period has not been completely resolved. The conventional use of single algae feeding without formula makes the nutrition insufficient Sufficiently inhibit the development of planktonic larvae in seedlings

Embodiment 1

[0008] Embodiment 1: The formula of basic bait for planktonic larvae of thick-shelled mussels contains: 65 to 72 parts of water bodies containing Isochrysis globosa, 65 to 72 parts of water bodies containing Isochrysis globosa, and Nannochloropsis or chlorella 8 to 16 parts of algae or a mixture of the two in any proportion, and 16 to 24 parts of water containing diatoms.

[0009] A unit of water contains clean seawater with the same number of living Monocellular algae cells.

[0010] Clean seawater containing Isochrysis globosa high-temperature strain "OA-3011" or other Isochrysis globosa species mixed with "OA-3011" in any proportion.

[0011] Clean seawater containing any single species of Nannochloropsis or Chlorella genus and its mixture, or any species within the two genera in any proportion.

[0012] Clean seawater containing any single species of diatoms or a mixture of any species of diatoms in any proportion.

Embodiment 2

[0013] Example 2: Basic bait formula for planktonic larvae of thick-shelled mussels, measuring 70 ml of seawater of Isochrysis globosa "OA-3011" with a cell density of 1.0 × 10 cells / ml, 14 ml of seawater of Nannochloropsis with the same cell density, and equivalent Cell density of diatom Phaeodactylum tricornutum seawater 16ml, mixed.

Abstract

The invention discloses a base bait formula for mytilus crassitesta planktonic larva. The base bait formula comprises the following components according to the parts of a water body containing monodus subterraneus of same cell density: 65-72 parts of water body containing isochrysis galbana parke, 8-16 parts of water body containing nannochloris oculata or chlorella or a mixture of the nannochloris oculata and the chlorella, and 16-24 parts of water body containing diatom. The base bait formula has the advantages of complete nutrition, good luring property, low bait coefficient, low cost and convenience in culture.

Description

technical field [0001] The invention relates to an artificial feed for aquatic products, in particular to a basic bait formula for planktonic larvae of thick-shelled mussels. Background technique [0002] Thick-shelled mussels are mussel varieties with high economic value in my country. Compared with purple mussels, thick-shelled mussels have the advantages of rich nutrition and good taste. It is mainly distributed along the coasts of the Yellow Sea, the Bohai Sea and the East my country Sea. Among them, Zhejiang Province has the largest amount of natural resources, and Shengsi County, Zhoushan City is the main production area of ​​thick-shell mussels. For a long time, the seed supply required for cultivating thick-shelled mussels has always relied on seedlings attached to natural sea areas and semi-artificial harvesting. However, in recent years, human development has intensified, resource damage has deepened, and the range of natural seedling farms has shrunk year by year...
