Description

  The present invention relates to a method for producing live fishing baits.

  As a live fishing bait in mountain streams and rivers, honey moth (scientific name: Galleria Melonella, also known as: Hachinosuzu Riga) larvae are widely used, usually hatched from eggs, and 20-40 days at a temperature of about 20 ° C to 35 ° C. Honey larvae raised to a certain extent are commercially available as live fishing baits. Honey moth larvae have the property of spawning to form cocoons and hatching over time, so even if they were larvae at the time of shipment, they formed cocoons and hatched during the distribution process. There were many times to do. In order to use the honey moth larvae that have formed wings as a live fishing bait, it is necessary to remove the honey moth larvae from the cocoons, and not only hatched honey larvae but also hatched honey moth larvae are not preferred as live fishing bait Met. For this reason, honey moth larvae that are less likely to hatch have been desired as live fishing baits.

  Under such circumstances, the present inventor diligently studied a method for producing honey moth larvae used as a live fishing bait that is more difficult to hatch. It has been found that the hatching of honey moth larvae can be suppressed by making them, and the present invention has been achieved.

  That is, this invention provides the manufacturing method of the live fishing bait characterized by immersing a honey moth larvae in warm water with an internal temperature of 45-55 degreeC.

  According to the present invention, honey moth larvae that are more difficult to hatch can be produced, so that there are many effective honey moth larvae that can be shipped as commercial products, which can be commercially advantageous.

  The honey moth (Scientific name: Galleria Melonella, also known as: Hachinosuzu Riga) larvae used in the present invention may be natural honey moth larvae, for example, artificially hatched honey eggs and reared at a temperature of about 20 ° C to 35 ° C. It may be a larva. When the latter honey larvae are used, larvae that are usually raised for about 20 to 40 days after hatching and bred 1 to 2 years before the final age are used. Moreover, since the weight of the honey moth larva is usually about 200 to 550 mg, the weight may be used as a guide.

  The present invention is characterized in that honey moth larvae are immersed in warm water having an internal temperature of 45 to 55 ° C., thereby suppressing hatching.

  The time for dipping in warm water having an internal temperature of 45 to 55 ° C. is usually 5 to 60 seconds, and may be determined according to the temperature of the warm water. For example, if the internal temperature is 45 ° C., the immersion time is preferably 40 to 60 seconds, if the internal temperature is 50 ° C., the immersion time is preferably 20 to 60 seconds, and if the internal temperature is 55 ° C. The immersion time is preferably 5 to 20 seconds.

  Honey larvae are usually immersed in warm water so that the entire honey larva is warmed substantially uniformly. For example, a predetermined number of honey moth larvae can be put into a metal or resin cocoon and the cocoon can be immersed in warm water.

  After completion of the immersion, the honey moth larvae are taken out from the warm water, allowed to cool, and then directly used as a live fishing bait. For example, after wiping off water droplets with a cloth or the like, the live fishing bait is preferably used. In addition, honey moth larvae are taken out from the warm water, re-immersed in water at an internal temperature lower than the immersion temperature, for example, 5 to 35 ° C., and cooled. The honey moth larvae are taken out from the water and allowed to cool or drop of water with a cloth, for example. After wiping off, it may be used as live fishing bait. The immersion time when the honey moth larva is immersed again in water having an internal temperature lower than the immersion temperature is usually 5 to 100 seconds. Further, instead of wiping off the water droplets with a cloth or the like, it may be dried with a dryer such as a dryer.

  EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail, this invention is not limited to these Examples.

Comparative Example 1
125 honey larvae were allowed to stand at room temperature. Three weeks later, honey moth larvae were classified into the following three stages according to the presence or absence of wrinkles and threads, and the ratios were determined. The results are shown in Table 1. The ratio of C was 79%, and the total ratio of A and B was just over 15%.

A ... Honey moth larvae that have not hatched, and no thread is seen B ... Honey moth larvae that have not hatched, and have a slight thread C ... Honey moth larvae that have hatched

Examples 1-8
Under the conditions shown in Table 1, 125 honey larvae were treated with warm water and cooled, respectively, and then allowed to stand at room temperature for 0.5 to 4 hours. Then, it stored at about 10 degreeC. Three weeks later, in the same manner as in Comparative Example 1, honey moth larvae were classified into the three stages according to the presence or absence of wrinkles or threads, and the respective ratios were determined. The results are shown in Table 1. The ratio of C was about 40% or less, and the total ratio of A and B was about 50% or more.

Examples 9-12
Under the conditions shown in Table 2, 100 honey moth larvae were each treated with warm water and cooled, and then allowed to stand at room temperature for 1 hour. Then, it stored at about 10 degreeC. Three weeks later, in the same manner as in Comparative Example 1, honey moth larvae were classified into the three stages according to the presence or absence of wrinkles or threads, and the respective ratios were determined. The results are shown in Table 2. The total ratio of A and B was 70% or more.

Comparative Example 2
100 honey moth larvae were immersed in warm water at an internal temperature of 40 ° C. for 60 seconds, treated with warm water, then taken out, immersed again in water at an internal temperature of 20 ° C. for 60 seconds, and then cooled. Honey moth larvae were taken out, wiped with a cloth, and then left at room temperature for 1 hour. Then, it stored at about 10 degreeC. Three weeks later, as in Comparative Example 1, honey moth larvae were classified into the three stages according to the presence or absence of wrinkles or threads, and the proportions were determined. A was 5%, B was 17%, and C was 67. %Met.

Comparative Example 3
100 honey moth larvae were immersed in warm water at an internal temperature of 60 ° C. for 10 seconds, treated with warm water, then taken out, immersed again in water at an internal temperature of 20 ° C. for 60 seconds, and then cooled. Honey moth larvae were taken out, wiped with a cloth, and then left at room temperature for 1 hour. Thereafter, it was stored at about 10 ° C., but almost all died after 3 weeks.
