Protocolo de anestesia y recuperación para estudio de morfometría de juveniles de caballito de mar, (Hippocampus hippocampus (Linnaeus, 1758)

Anaesthetic and Recovery Protocol for morfometric study of Atlantic seahorse, Hippocampus hippocampus (Linnaeus, 1758), juveniles. Some morphometric studies in marine organism need anaesthetics in order to avoid animal?s sacrifice and allow its recovery. In this study different natural clove essential concentrations has been tested in Atlantic seahorses, Hippocampus hippocampus (Linnaeus, 1758) aged 13 (trunk length 7,48 ± 1,14 mm) and 22 days (trunk length 9,09 ± 1,62 mm). An inversed relation was observed between anaesthetic concentration and effective time. The concentration allowing measures was 25 ppm. This procedure allowed 100% survival rate.
