Description

Panti clam breeding box

Technical Field

The invention belongs to the technical field of aquaculture, and particularly relates to a geoduck clam culture box.

Background

Geoduck (elegant sea clam) is native to the coastal region of Alaska to northern California, USA, and belongs to the Pacific species. The water temperature of the living sea area is 2-23 ℃ (0-25 ℃), the salinity is 27.5-32.5, the water depth is 4.1-18.3 m, and the sand bottom or sand mud bottom can live. The shellfish is large in size, fast in growth and high in economic benefit. At present, the annual output of America and Canada is about 3000t, except for selling to the local, the America and Canada are mainly exported to countries in southeast Asia and China, the annual income is 3-4 hundred million dollars, wherein the elegant Marble clams sold to China are about 1000 t, and the output value reaches 1-1.2 million America.

The cultivation sea area needs to select an inner bay which is small in wind wave, rich in bait and mainly made of sand. The culture water depth can be from below the low tide line to about 10m, the water temperature is not lower than 0 ℃ in winter, and the water temperature is not higher than 25 ℃ in summer. The seedlings have the capability of submerging in caves, the individual submerging speed is low, and the stone is buried and perched deeply; individuals dive quickly when small, but land shallow. The sand-submerging capability of the seedlings with the shell length of 4-8 mm is strongest, only 3-5 min is needed, and the sand-submerging rate can reach 100%; some of the shells, which are more than 20mm long, lose their ability to lodge in the cavities due to foot degeneration. The seedling has the strongest sand-hiding capability at the water temperature of 11-17 ℃, and has poor sand-hiding capability at the water temperature of less than 9 ℃ and more than 23 ℃. In addition, the sand-burying capability of the salinity object mussel is also greatly influenced, the sand-burying capability is normal when the salinity is 27-32, and the sand-burying capability is sharply reduced when the salinity is lower than 26.

Because the survival rate of the freshwater mussel sowed in the sea and maintained by the net basket is low, the freshwater mussel cultivation box which is high in cultivation survival rate, strong in stability and not easy to damage is urgently needed in the market at present.

Disclosure of Invention

The invention aims to provide a panopea abrupta cultivation box, which can effectively reduce cultivation cost, can automatically feed, is not easy to damage, has a better pollution discharge function and can promote the growth of the panopea abrupta.

The scheme adopted by the invention for realizing the purpose is as follows: geoduck breeding box, including breeding the case, breed incasement portion and be equipped with the string bag, the string bag passes through the fixed cable and connects breed incasement wall, breeds the one end of case upper end joint support post, and the lower surface of kickboard is connected to the other end of support post, and the upper surface of kickboard is equipped with washing water pump, oxygen pump, pneumatic cylinder from a left side to the right side in proper order, throws the material device. This breed case simulation geoduck that can be fine buries the characteristic of perching, and it is fast than the geoduck growth rate of ordinary breed under the situation that bait is sufficient simultaneously to can be better avoid the enemy, guaranteed the survival rate of geoduck in the breeding process, improved economic benefits, the string bag of breeding the incasement is detachable, the collection of the geoduck of being convenient for and the washing of string bag, this device degree of automation is high, and is multiple functional, and it is effectual and the survival rate height to breed.
