Have you seen fish swimming in a river? A city in the Netherlands has a river where fish swim. From May to the end of June, they swim to find places to lay eggs. But there's a gate in the river.
你看過在河裡游泳的魚嗎?荷蘭有一條河從五月到六月底都會有魚通過，準備找地方產卵，但是這條河有個閘門。
The gate opens for boats. Fish can go through at the same time. But when there are no boats,* *they have to wait… and wait… and wait. Sometimes hungry birds find them.
有船要通過的時候，閘門就會打開，魚這時可以跟著通過。但是如果沒有船，牠們就要一直等，中途可能就會被鳥吃掉。
So a scientist made a fish doorbell! But fish don’t ring the doorbell. People do!
於是科學家做了魚群專用的門鈴，魚當然不會按門鈴，人才會!
An underwater camera lets people see the gate. When people see fish there, they ring the doorbell. A worker opens the gate.
河裡還有水下攝影機讓大家看到閘門。只要有人看到魚在等，就可以按門鈴讓管理員開門。
Where's the doorbell?It's on the Internet! It's very popular. It lets people help fish. It teaches people about underwater life. They see many kinds of fish.
在哪按門鈴呢? 門鈴就在網路上，大家可以幫助魚又可以認識水生動物，還可以看到各種魚類。
Early morning and early evening are the best times to see fish. There aren't many hungry birds then…
每天清晨跟黃昏是看魚的最佳時機，這個時候也不會有太多飢餓的鳥類。
The fish doorbell is a fun way to help fish. Some people in Taiwan have helped! Do you want to help too?
