Descriptions
A long term study on the surf zone ichthyofauna in an open sandy shore at Fukiagehama, southern Kyushu Island was carried out using experimental beach seine with 26 m net width, 2 m depth and 4×4 mm square meshed fish bag, in every spring and autumn from 2000 to 2010 and 2013 with additional summer sampling in 2000, 2001, 2006 and 2007. A total of 52,340 individuals from 44 families and more than 85 species were captured in 540 daytime and preliminary 24 nighttime hauls. The surf zone fish community was dominated numerically by ten species such as Sillago japonica(40.0 %), Trachurus japonicus(14.3 %), Hypoatherina valenciennei(13.1 %), Mugil cephalus cephalus(7.1 %), Engraulis japonica(6.6 %), Takifugu niphobles(6.2 %), Lateolabrax latus(3.9 %), Sphyraena japonica(1.9 %), Paraplagusia japonica(1.6 %)and Paralichthys olivaceus(1.0 %), and taxonomically by Carangidae(11 species), Clupeidae(7 species), Gobiidae(more than 6 species)and Sparidae(4 species). Relatively large proportion of individuals in late developmental stages such as late juvenile, young and adult dominated the community. The ichthyofauna was also characterized by relatively few species having strong temporal ssociation with surf zone habitat and mixture of demersal, reef and pelagic inhabitants.
