Abstract
Gobiids belonging to the genus Stiphodon are amphidromous fish that inhabit coastal streams, and they traverse through above average flow conditions and often occur above waterfalls during upstream migration. These fish possess a pelvic sucker (fused pelvic fins) that allows them to adhere to surfaces in the fast flowing streams that they inhabit. Through the use of their pelvic sucker, Stiphodon gobies have the ability to cling to rocks and other hard surfaces present in the streams,which helps facilitate the goby’s migration throughout their native streams and allows them to resist strong currents. In this study, selected groups of Stiphodon ornatus were run through endurance training where they were placed in an inclined-gutter flow-through-system (minimum of 6 hrs/day) that simulates flow conditions that are designed to encourage natural, instinctive clinging behavior in the fish. After several end-points of the training (every week for 4 weeks), biochemical assay was conducted for quantifying endurance-associated gene expressions in the pelvic muscles that actuate the pelvic sucker. We will discuss the implication of our findings
