Engorde de pulpo (Octopus vulgaris) alimentado exclusivamente con boga (Boops boops) de descarte de la acuicultura

[EN] The use of low value fish (Bogue, Boops boops), accidentally reared in seabream culture cages, as a sole food in octopus farming was tested in two different experiments located in Canary Islands. In a first experiment two different initial sizes were compared: 1,5 kg & 2,3 kg, both at a density of 11 kg/m3. Initial density was increased in a second experiments to 16 kg/m3 testing two lower initial weights: 1,0 kg & 0,8 kg. Bogue as a single feed was found to be good enough to sustain a good growth in octopus cage rearing. Best growth in terms of specific growth rate and average daily growth was obtained with the lowest grow size, 0,8 kg.
