  1. Create long flexible habitats (>50 mm) on subtidal artificial structures

    A replicated study in 2003–2004 on two subtidal jetties in Sydney Harbour estuary, Australia (Clynick 2008) reported that long flexible habitats (nets) created on jetty pilings were used by two species of seahorse. Over 10 months, between one and three White’s seahorses Hippocampus whitei were seen on nets attached to jetty pilings during three of five surveys at each of two sites. One big-belly seahorse Hippocampus abdominalis was seen during three of the surveys at one site. Two juvenile seahorses were seen on nets. Long flexible habitats were created by attaching five nets (length: 5 m; height: 3 m; material not reported) to wooden jetty pilings at each of two sites in May 2003. Nets were in contact with the seabed (depth not reported). Seahorses on nets were counted over 10 months.
