Ark clams (Anadaraspp.) are one of the potential fishery resources off the East Coast of Surabaya. The purpose of this research was to determine the condition and stock status of Anadara spp. The biomass dynamic model was the method used to obtain the stock status of this species. For the estimation of biomass, starting in 1960, it continued to increase until finally it stabilized. Starting in the 2000s, the condition of the ark clam biomass began to decline. For the limit reference point (LRP), the value is expected to be about 7,215.55 tons with a catch effort (fmsy) of 334 units and with the Bmsy being 6,7121,38 ton; this includes MSY. For the condition of the stock in 2016, the catch was 1,2957 ton and the effort was 445 units. This means that the actual stock of the ark clam (Anadara spp.) off the East Coast of Surabaya exceeds the MSY, fmsy, and Bmsy. This is an indication of overfishing in the coastal area. © Published under licence by IOP Publishing Ltd.
