Con la finalidad de intercambiar ejemplares vivos de Octopus vulgaris Cuvier, 1797 entre centros de investigación o instalaciones de empresas, se han desarrollado dos técnicas de transporte: la primera para el traslado de paralarvas, utilizando bolsas plásticas de 30 l con agua de mar (1/3 de su capacidad) y O2 (2/3 restantes), y la segunda para adultos de aproximadamente 1 kg de peso, que se introducirían en tubos de PVC de 16 cm de diámetro, revestidos por malla de red y ubicados en un tanque de 200 l con aireación. Los ensayos fueron realizados durante 24 horas a diferentes temperaturas y densidades de estabulación. En el caso de las paralarvas, los mejores resultados (mortalidad inferior al 1 %) fueron obtenidos a una temperatura de aproximadamente 14 oC y con densidades de hasta 3 000 indiv l¿1; para los adultos se obtuvieron mortalidades menores del 5 % en un rango de temperaturas de 13 a 19 oC y densidades de hasta 165 kg m¿3.
In order to exchange live samples of the octopus Octopus vulgaris Cuvier, 1797 among research laboratories or companies, two techniques of transportation were developed: the first one for paralarvae, in 30 l plastic bags filled with seawater (1/3) and O2 (2/3), and the second for adults with a mean weight of about 1 kg, placed in 16 cm diameter PVC tubes covered with mesh in a 200 l tank. Trials were made at different temperatures and densities, during 24 hours. The best results for paralarvae (mortality < 1 %) were obtained with a temperature of about 14 oC at a density up to 3 000 indiv l¿1, while mortalities lesser than 5 % were obtained for adults in a temperature range of 13 to 19 oC and density of up to 165 kg m¿3.
