<br />ou~u <br /> <br />sound. We don't know exactly what it is. <br />Perhaps some of you have seen some popularized <br />articles of people discovering or suggesting <br />that fish can talk. Why shouldn't they? It's <br />reasonable that they should communicate. We <br />know that there is some sort of communication <br />and we have, within the last few months, <br />developed a technique of actually recording <br />the voices, if they are voices, but at least <br />signals, a tensor type of signal, on magnetic <br />tape. We can play these back and we can <br />actually hear a conversation of trout as they <br />undergo various stresses and strains. We can <br />do this with numerous types of fishes. Our <br />big problem right now is to clear up the signal <br />but we feel that we will soon have a device. <br /> <br />I <br /> <br />This is a group of trout placed in an <br />aquarium and invited to dinner (using traced <br />tapes). The first one is a traced pattern of <br />no fishes at all, the dark line indicates no <br />fish. There is one blip in there where we put <br />one into the aquarium and perhaps he voiced a <br />protest as he went in. The others here are <br />very definite conversation patterns (using <br />another tape) as we applied food to the <br />aquarium. The trout came up and these patterns <br />are so specific that we feel as soon as we find <br />the equipment we will be able to trace exactly <br />and measure these patterns so we can find out <br />the behaviour pattern. We hope to coordinate <br />this on film. <br /> <br />We have a study that we plan to start. We <br />have a very small faculty improvement grant just <br />funded that we hope to be able to buy a little <br />equipment to work on this. We say ~hy can't we <br />ask the fish if the water is too hot? We are <br />making all kinds of statements. We are saying I <br />that water should be 85 degrees or 95 degrees <br />or 60 degrees or some other observed tempera- <br />ture that we collectively decided is lenient <br />or satisfactory. But there is no better method <br />than asking the animal itself. Up to this <br />point we haven't been able to ask the fish <br />except whether it dies or not and this is rather <br />
