Tuna Stocks

One of our staple evening meals is tuna pasta bake – tinned tuna, fusilli pasta, tomato based sauce, mozzarella cheese, peas and sweetcorn with toasted cheddar cheese on top – and with it on the menu for tonight I checked the cupboard for the stock of tuna; with twenty-five tins there, the stocks in the cupboard were fine, but I guess the implication for stocks in the ocean were less rosy.
