I think she is going to open the boxes and feed the fish. Or: I think she is on her way to the market to sell the fish. The first thing to do is to go out in the boat and see if anything is caught in the nets. Next, you have to bring in the fish and throw out the nets for the next catch. Then, the fish must be brought to land. The fish should be kept in big boxes full of water, so they dont die.

Listening text Hello, my names Helen and I live on the west coast of Canada. I work on a fish farm. Right now Im feeding the fish, which are kept in cages inthe sea. The cages are tied to the rocks on the bottom of the sea. It can get very windy here.Twice a day I put the fish food in theboat and go out to the cages. The fish are always hungry! When the fish have grown to the right size, we pull the cages out of the water. The fish are killed and cleaned. Our fish farm is a long way from the nearest market. So we either freeze the fish or smoke them. We dont salt any fish here. Some fish farms do, but we dont.
Three of us work here and theres always a lot to do. Inside that building over there we have tanks for the young fish. We produce all our own fish from eggs. The fish start to grow in fresh water. Then, when they are bigger they go into the sea, which is salty, of course. Theres always a lot of work to do: feeding the fish, cleaning the tanks, getting eggs out of the best of the large fish, harvesting the fish, cleaning them and smoking them. We burn our own wood and that way we get a very good strong smoke. Its more work, but we get higher prices for our smoked fish.
