Abstract

Pisciculture is currently an agricultural activity that is becoming increasingly important in a worldwide scenario, since it allows an alternative for fish production beyond fishing. And in this way it contributes offering quality food to the consumer market. However, when it comes to the consumer market, one can already imagine a productive chain behind that product, which is true for several species of fish with greater or lower added value. Nevertheless, fish farming is not only linked to agribusiness as a production chain, but it is also responsible for food security of populations in situation of social fragility. Thus, yes, answering the first question of this text, the study of alternative foods is important for fish nutrition. However, not only for commercial fish farming where the demand for alternative foods is important for the production of cheaper diets with the same or better quality than those formulated with conventional ingredients, but also for those who need regional ingredients to compose artisanal rations to feed fish raised for subsistence. An alternative food can come from a variety of sources such as industrial waste, locally produced agricultural products, or in less quantity, foliage, fruits etc.
