Embodiment Construction

[0014] The method for cultivating variegated clams of the present invention takes the following site as an example: the annual average temperature is 12.6°C. The annual sunshine time is 2530 hours, the average surface water temperature of seawater is 14.7℃, the salinity is 28‰~3l‰, the tide is regular semidiurnal tide, the average tidal range is 300cm, the pH value of coastal seawater is 8.15~8.35, and the seawater transparency With an average of 5.3m, the water flow is smooth and smooth, the water exchange is sufficient, and the bait organisms are rich, which is suitable for seawater shellfish farming.

[0015] Seedling selection, clam seedlings come from natural seedlings in the intertidal zone of Rizhao City, select seedlings with smooth body surface and no damage, shell length of 2cm-3cm or 140 grains / kg-180 grains / kg, and remove mixed flat clams. Jade snails, fragrant snails, red snails and other harmful organisms.

[0016] Seedling density and time: 110 cages per mu, 10...

Abstract

A short necked clamp breeding method comprises the following steps: (2) site selection, (2) young short necked clam selection, (3) young short necked clam throwing, (4) raft preparation and (5) daily management. According to the short necked clam breeding method, water quality is severely controlled, baits are scientifically fed for the short necked clams, therefore, the short necked clams grow rapidly and do not have diseases or parasites, the meat quality is good, and the yield is high.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to the cultivation technology of variegated clams. Background technique [0002] Philippine clam, usually also known as variegated clam or Philippine clam, has a shell length of 2.5-5.7 cm. Commercial size averages 40mm. It is a common shellfish. Edible, with high nutritional value, delicious meat, rich nutrition, high protein content, reasonable composition and proportion of amino acids; low fat content, high unsaturated fatty acids, easy to be digested and absorbed by the human body, and various vitamins and medicinal ingredients. Containing calcium, magnesium, iron, zinc and other trace elements necessary for the human body, it can be used as human nutrition and green food, and is favored by consumers. Clam meat and shellfish mollusks contain a kind of delta 7-cholesterol and 24-methylene cholesterol that can lower serum cholesterol. They have the unique ef...
