“…However, the low survivorship of juvenile seahorses and low reproductive efficiency of the broodstock seahorses have restricted seahorse culture for many years (Herald and Rakowicz, 1951;Scarratt, 1995;Wilson and Vincent, 1998;Wong and Benzie, 2003;Lin et al, 2006). Therefore, recent research works have mainly focused on the growth and survivorship of juveniles (Scarratt, 1995;Woods, 2000Woods, , 2003aSheng et al, 2006;Lin et al, 2008), and on broodstock reproduction (Selman et al, 1991;Vincent, 1995;Teixeira and Musick, 2001;Perante et al, 2002;Lin et al, 2006Lin et al, , 2007Faleiro et al, 2008). The effects of illumination, feed ration, stocking density and gender segregation on growth and survival have been examined in Hippocampus abdominalis (Woods, 2000(Woods, , 2003a(Woods, , 2005.…”
