Tiny injectable beeping tags used to track salmon

In order to study how young fish such as salmon are affected by swimming through hydroelectric dams, scientists have traditionally equipped them with surgically-implanted acoustic tracking tags. Unfortunately, the implantation procedure can harm the fish, plus the weight of the device can affect their behavior. Now, however, a team at the Pacific Northwest National Laboratory (PNNL) in Washington state has developed a much lighter acoustic tag, that can be injected into fish using a needle. ..
