Conventionally, in order to facilitate smooth response at the landing port for skipjack and tuna fishing, fishing boats have been informed of the approximate amount of landing to the port prior to entering the port.
前記方法によれば、例えば、港における市場での競りに際し、参加者が、事前に水揚げ量の情報に基づき競りへの参加の要否を判断することができるため、競りの参加者が入荷量に対して多すぎたり少なすぎたりすることをある程度防ぐことができる。
According to the method, for example, in a bid at a market in a port, the participant can determine whether or not to participate in the auction based on the information on the amount of landing in advance. It can be prevented to some extent that it is too much or too little.
しかしながら、漁船における水揚げ量の予想は、漁師の感覚によるため、魚の数、種類、大きさ等の正確な情報を得ることができず、例えば、実際の水揚げ量が、予想とは異なる場合がある。この場合、競りの参加者が入荷量に対して多すぎたり少なすぎたりすることで、商品となる魚が不足したり、競りの価格が変動し、問題となっていた。
