Temperature-induced changes of growth and survival in the early development of the seahorse Hippocampus guttulatus

The effect of temperature (15, 18 and 21 °C) on the early development of the long-snouted seahorse Hippocampus guttulatus were analysed, both under feeding (until day 30 post partum) and starving conditions. Fed and starving seahorses maintained at 15 °C grew at suboptimal conditions. At this temperature, mortalities started earlier and the swimming activity was reduced. In fed juveniles, final survivals (21.1, 85.9 and 81.1% at 15, 18 and 21...
