Polydora uncinata (Polychaeta: Spionidae) in Chile: an accidental transportation across the Pacific

Abstract

A Polydora species was found boring in shells of the abalone Haliotis discus hannai cultivated in landbased tanks in Coquimbo, Chile.

Morphological and molecular sequence analysis of the harmful shell boring species of Polydora (Polychaeta: Spionidae) from Japan and Australia

“…The three species of the genus Polydora investigated in this study have caused severe damage to commercially important mollusk shells in Japan , South Korea (Sato-Okoshi et al, 2012), Australia (Sato-Okoshi et al, 2008), and Chile (Radashevsky and Olivares, 2005). The scallop Patinopecten yessoensis in Okhotsk Sea, Hokkaido, Japan, and sown and suspended cultured scallops in Mutsu Bay, northern Tohoku District, Japan, were heavily infested by large Polydora brevipalpa (Mori et al, 1985;.…”

“…Although they excavate their burrows for use as a habitat, some species have been frequently reported as harmful invaders from the viewpoint of molluskan aquaculture, as they often damage the commercially important mollusk shells by decreasing their commercial value, reducing their growth rate and meat yield, and causing heavy mortality (Handley and Bergquist, 1997;Lleonart et al, 2003;Mori et al, 1985;Sato-Okoshi et al, 2008Simon et al, 2006). Currently, species of Polydora and related genera that associate with mollusk shells appear to have spread outwardly by accompanying commercially important host shells that have been transported worldwide (Radashevsky and Olivares, 2005;Simon et al, 2006). These species are a source of concern not only from the perspective of aquaculture but also as invasive species (Cohen and Carlton, 1998).…”

Morphology, 18S rRNA gene sequence and life history of a new Polydora species (Polychaeta: Spionidae) from northeastern Japan

“…Commercially important mollusk species affected by polydorid infestation include scallops (e.g. Sato-Okoshi 1994, 1999, Radashevsky & Olivares 2005, oysters (e.g. Handley & Bergquist 1997, Sato-Okoshi 1999, Sato-Okoshi & Takatsuka 2001, pearl oysters (Mohammad 1972, Sato-Okoshi 1999, abalone (Sato-Okoshi 1999, Radashevsky & Olivares 2005, Sato-Okoshi et al 2008, mussels (Kent 1979, 1981, Ambariyanto & Seed 1991 and clams (Caceres-Martinez et al 1999).…”

Polydorid species (Polychaeta: Spionidae) in south-western Australian waters with special reference to Polydora uncinata and Boccardia knoxi

“…In south-western specimens, the length of the long axis of oval eggs in egg capsule was 175 mm on average. The size of the eggs of the Chilean specimens extracted from land-based cultured abalone was reported by Radashevsky & Olivares (2005) to be 170 -175 mm  133 -138 mm in diameter. So the size of the eggs of the species seemed to be 170 -175 mn in long axis.…”
