Abstract: All marine invertebrate larvae exhibit habitat preference for settlement which is mediated by positive or negative cues. Recruitment of the false limpet Siphonaria guamensis (S.g) occurred only on the rocks where the invasive crustose red alga (CRA) Hildenbrandia prototypus (H.p) is distributed, but there was no study to date on the larval settlement preference of S. guamensis This study was aimed to prove that the larvae of S.guamensis settles on the rocks covered by H. prototypus. The larval habitat preference of S. guamensis was investigated conducting experiments in the laboratory aquaria, exposing the larvae to native and invasive substrata that occur in the rocky coast of Visakhapatnam, east coast of India. Three different types of experiments were designed to study the settlement preference as 1. Each type of rock in separate aquarium (one set with rocks covered by H. p and another set with bare rocks, each set with 10 replicates), 2. All types of rocks covered by H. p placed in one aquarium and all types of bare rock substrata in another aquarium (named as 7 way experiment), 3. Pair-wise experiments, rocks covered by H. p coupled with bare rocks. Larvae rejected the bare rocks as substratum. Only very few larvae settled on those bare rocks consists of spat, live adults, dead shells of S. guamensis and thalloid algae (1:1). In the pair-wise experiments undertaken in the individual aquaria, settlement is significantly high on the rocks covered by H. prototypus.
