Abstract(s)
O objectivo desta dissertação era o desenvolvimento de dietas económicas que
permitissem o cultivo em grande escala do choco, Sepia oficinalis. Esta foi dividida em
duas grandes áreas de investigação, referentes aos hábitos alimentares das diversas fases da vida do choco, associados ao tamanho e à idade. A primeira parte focou os aspectos de cultivo de misidáceos para alimentar os juvenis de choco. A segunda parte consistiu em determinar os efeitos de dietas artificiais (em substituição de dietas naturais como camarão ou peixe congelado) no cultivo do choco, e determinar se estas poderiam substituir com sucesso as dietas naturais que são normalmente utilizadas.
The objective of this dissertation research was to enable the mass culture of Sepia ofitcinalis through the development of inexpensive diets. It was divided into two major areas concerning the feeding habits of S. officinalis according to their age and size. The first part focused on the culture of mysids to feed hatchling cuttlefish. The second part consisted on testing the effects of artificial surimi diets fed to cuttlefish and deterrnine if they could successfully replace natural food (frozen shrimp or fish) that are nonnally used.
