る。Generally, in pearl culture, a mother shellfish farmer first collects juvenile shellfish and cultures the mother shellfish. The pearl farmer purchases the mother oysters and carries out pearl cultivation through the steps of mother oyster training, mother oyster tailoring, core insertion surgery, pearl oyster training, and beach raising. At this time, it is known that there is a high correlation between the rate of non-defective pearls and the vitality of the mother oysters, that is, the health condition. Mother-shell aquaculture companies want to grow healthy shellfish as much as possible and sell it at a high price. Pearl farmers want to buy cheap shellfish at a cheap price. However, in the current selection, much depends on the individual sense such as presence or absence of harmful parasites by visual inspection. Therefore, it is required to establish a uniform evaluation method between both companies and clarify the selection class of shellfish before realizing the transaction. Moreover, the pearl farmer needs to control the training and control of the purchased shellfish well, and carry out the nucleation and the pearl shell training under the optimum conditions. Therefore, it is desired to adjust the breeding and fishing grounds, the amount of feed, and the control method while constantly diagnosing the vitality of shellfish.

It's called vitality, and I'll call it vitality here. Recently, the index of this vitality measurement is being developed by the analysis of chemical constituents in shellfish. Well-known indicators of shellfish vitality include the amount of serum proteins and lipids in shellfish, and the ratio of dry shellfish weight to shell internal volume.

操作にて選別する装置を提供することを目的とする。However, the measurement of vitality of shellfish by the above-mentioned conventional index is not popular in the field work because the analysis method requires much labor. For this reason, no grade selection has been performed to improve efficiency in transactions and the acquisition of good quality pearls, and they rely on visual inspection as usual. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and provide an apparatus for selecting the superiority or inferiority of the vitality of cultured shellfish by a quick and simple operation.

することが有効である。In order to achieve this object, the sorting apparatus of the present invention uses the amount of glucose in shell meat or body fluid as an index for measuring the vitality of shellfish. Regarding the glucose amount measurement, a quick and simple measuring method has been established in the blood glucose level measurement in the medical field (for example, JP-A-4-357452). In addition, it is effective to measure the glucose concentration in the adductor muscle (scallop), which has a particularly high glucose content in shellfish.

して有効である。It has been experimentally confirmed that there is a strong correlation between the amount of glucose in shellfish or body fluids, especially in the scallop, and the vitality of the shellfish. The more active the shellfish, the higher the glucose content. According to this method, the vitality of shellfish can be measured more quickly and easily than in the conventional case where lipids and serum proteins are used as indicators, and the superiority or inferiority of shellfish can be selected on site. Therefore, it is effective as a method of evaluating and diagnosing mussels for trading of mussels or training and control of mussels.

印刷用プリンター部である。An embodiment of the present invention will be described below with reference to the drawings. The vitality of shellfish strongly depends on the aquaculture area or the fishermen (population). Therefore, it is possible to evaluate each population by sampling an appropriate number of shellfish from each population. Split the shellfish and remove only the scallop. This device is roughly composed of three parts: a part for crushing a scallop and extracting a body fluid, a part for measuring a glucose amount, and a part for analyzing data. In FIG. 1, 12
Is a mixer for crushing the scallop 11, 13 is a piston for extracting body fluid from the crushed scallop, 14 is a sensor for measuring the amount of glucose described in JP-A-4-357452, and 15 is Electronic circuit unit that calculates glucose level from sensor signal and displays grade discrimination, 16
Is a computer unit for storing and statistically processing glucose amount data by shellfish or by population. Reference numeral 17 is a printer unit for printing measurement results.

式を用いてグルコース値に換算され表示される。The operation of the shellfish vitality selection device configured as described above will be described with reference to FIG. Enter the sample name of the shellfish into the computer and insert the scallop into the device. The scallops are first ground to facilitate collection of body fluids. Next, the body fluid of about 0.1 cc can be easily obtained by compression by the piston 13. The sensor unit 14 is composed of a reagent enzyme and an electrode, and has the same principle as a conventional blood glucose level measuring device. The volume of body fluid required for one measurement is 20 μl or less. The sensor unit 14 considers the reliability of the measured value and the simple operation,
It is a "disposable" type that is replaced with a new one after each measurement. The obtained sensor signal is converted into a glucose value and displayed by using a preset conversion formula.

る。In this case, the accuracy of measuring the glucose concentration in body fluid is about ± 5% as in the case of the conventional blood glucose level measurement result. If the grade discrimination formula based on the glucose amount and the vitality of shellfish is input in advance, the grade discrimination corresponding to the obtained glucose value is also displayed at the same time. The time required to reach this point is within 3 minutes. The average glucose concentration of normal live Akoya oysters was about 300 mg / dl, but
It was below 200 mg / dl. Glucose levels obtained by shellfish, aquaculture and fishery, and by trader are immediately statistically processed, and the results for each item are output in a graph or table. At this time, it is also possible to work up to the data storage unit on site and perform statistical processing by a computer installed at another place.
