Octopus vulgaris: Ongrowing

Abstract

This chapter covers the most important topics related to the common octopus Octopus vulgaris ongrowing from an experimental and commercial standpoint, citing the most outstanding works of the last decade on the subject. It first describes the current situation and then lists the parameters that are most important in the rearing process, from the purely environmental (salinity, temperature, oxygen, nitrogen compounds) to those related to the biology of the species studied such as growth rate and survival in relation to sex, initial body weight and stocking density. It also provides information on ongrowing performance depending on the type of food, natural or formulated and the degree of acceptance of this with respect to its texture. Finally, we present results of growth in tanks and sea cages and give recommendations on the transport of live octopus.
