Fish have ears. Really. They’re quite small and have on opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths.

As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate. By looking through a microscope and counting these rings, Thorrold can determine the exact age of young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about fish’s age, just like the growth rings of a tree.

Ring counting is nothing new to fish scientists. But Thorrold has turned to a few direction. They’re examining the chemical elements of each otolith ring.

 The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring.

Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history.

In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant successfully followed the traveling of young fish from mid-ocean to the coast, a journey of many hundreds of miles.

This is important to managers in the fish industry, who know nearly nothing about his technology, fish scientists are now lending Thorrold their ears.

The kitchen of Mr Stokes’ small house in the south of London. Clean and Tidy.

Albert, a young man of 28, is standing in his shirt and trousers, combing his hair in the kitchen mirror over the mantelpiece. A woman’s voice calls his name from upstairs. He ignores it , picks up a brush from the mantelpiece and brushes his hair. The voice calls again. He slips his comb in his pocket, bends down, reaches under the sink and takes out a shoe duster. He begins to polish his shoes. Mrs Stokes goes down the stairs, passes through the hall and enters the kitchen.

Mother:Albert! Albert! Albert, I’ve been calling you.(She watches him.) What are you doing?

Albert:Nothing.

Mother:Didn’t you hear me call you, Albert? I’ve been calling you from upstairs.

Albert:You seen my tie?

Mother:Oh, I say, I’ll have to put the flag out.

Albert:What do you mean?

Mother:Cleaning you shoes, Albert? I’ll have to put the flag out, won’t I?

   Albert puts the brush back under the sink and begins to search the sideboard and the cupboard.

What are you looking for?

Albert:My tie. The striped one, the blue one.

Mother:The bulb’s gone in Grandma’s room.

Albert:Has it?

Mother:That’s what I was calling you about? I went in and switched on the light, and the bulb had gone.

  She watches him open the kitchen cabinet and look into it.

     Aren’t those your best trousers, Albert? What have you put on your best trousers for?

Albert:Look, Mum, where’s my tie? The blue one, the blue tie, where is it? You know the one I mean, the blue striped one, I gave it to you this morning.

Mother:What do you want your tie for?

Albert:I want to put it on. I asked you to press it for me this morning. I gave it to you this morning before I went to work, didn’t I?
