“…This is in line with the study of Bigatti et al (2009), who recorded TBT pollution in the sediments in Mar del Plata. In this study, no histological alterations in gonad structure were observed, and in consequence the gonadal cycle was not affected.…”

Olivancillaria deshayesiana (Gastropoda: Olividae) is distributed from Ilha Grande (Rio de Janeiro, Brazil) to Necochea (Buenos Aires, Argentina). Apart from some descriptions of the embryonic development and the egg capsules, little is known about the reproduction and ecology of this species. In this 2 yr study (October 2005 to September 2007, the reproductive cycle of O. deshayesiana was examined in a population highly affected by imposex, from the Mar del Plata coast, Argentina. Males exhibited seasonal reproductive activity, with a major spawning period from September to January (spring to early summer) for the 2 yr, which coincided with an increase in seawater temperature and photoperiod. In contrast, females were mature and capable of spawning year round, with a major spawning period from September to January (spring to early summer), simultaneous with the major spawning period of males.KEY WORDS: Imposex · Mar del Plata · Olivancillaria · Olividae · Reproduction Resale or republication not permitted without written consent of the publisherAquat Biol 15: [111][112][113][114][115][116][117][118][119] 2012 this species may grow to a total shell length of 31 mm in about 10 yr. The aim of our study was to describe the gonadal structure and reproductive cycle of O. deshayesiana, and to provide new information on the occurrence of imposex in a population in the Mar del Plata area, Argentina. MATERIALS AND METHODS SamplingMar del Plata (38°20' S, 57°37' W) is an open coast and the site of the most important coastal fishery fleet of Argentina (Penchaszadeh et al. 2001). In this area, water temperature ranges seasonally between 8.4 and 20.8°C and salinity is rather constant at 33.8 ‰ (www. iafe.uba.ar/tele/Antares_argentina/; Guerrero & Piola 1997).Specimens of Olivancillaria deshayesiana were collected monthly by bottom trawling (3 m mouth opening, 15 mm mesh size) off Mar del Plata City between 5 and 12 m deep from October 2005 to September 2007. Approximately 20 snails were caught each month and taken to the laboratory, where the shell was separated from the soft body. Shell length (SL) was measured with a Vernier caliper to the nearest 1 mm, and the shell-free wet mass (SFWM) was weighed to the nearest 0.1 g. To establish the morphometric relationship between SL and SFWM for each sex, linear regression analyses were performed using log(SFWM) = log(a) + b × log(SL). Parallelism tests and analysis of covariance (ANCOVA) were performed to compare the relationship between SFWM and SL between sexes (Sokal & Rohlf 1995). A chi-squared test was used to test for significant differences in sex ratio. Statistical analysis was carried out with the software Statistica v. 6.0.Recently, Teso & Penchaszadeh (2009) reported that this population is affected by imposex, and on this account animals were sexed by differences in gonad color and the presence (females) or absence (males) of internal sexual glands such as capsule and albumen glands. Sex was confirmed by the histological examination of gonad sections under...

“…In the Mar del Plata region, imposex has been reported for other gastropods, all associated with the harbour (Penchaszadeh et al 2001, Cledón et al 2006, Teso & Penchaszadeh 2009). Though the percentage of imposex-affected females was low, the high RPLI indicates a higher sensitivity of A. beckii to TBT in comparison to other snails studied in Mar del Plata (Penchaszadeh et al 2001, Cledón et al 2006, Bigatti et al 2009, Teso & Penchaszadeh 2009). …”

“…Imposex is a widespread phenomenon caused by tributyltin (TBT), a compound used in antifouling paint (Gibbs et al 1988(Gibbs et al , 1991(Gibbs et al , 1997, and has been reported in several coastal gastropods, particularly in species associated with harbour waters (Santos et al 2000, Bech 2002, Bigatti et al 2009). The Mar del Plata harbour is the most important fishing harbour in Argentina, with a coastal and offshore fleet of more than 300 vessels (Errazti & Bertolotti 1998).…”

Adelomelon beckii (Broderip, 1836) (Neogastropoda: Volutidae) is endemic to the western south Atlantic coast. It inhabits sandy bottoms in waters between 40 and 70 m deep and is one of the largest top benthic predators found in Mar del Plata, Argentina. The present study describes gametogenesis and the reproductive cycle of this species. Oocytes developed in close association with follicle cells, which appear to play a role in yolk synthesis and oocyte resorption, providing the key functions of phagocytosis and intracellular digestion of degenerating oocytes. Spermatogenesis resembles that reported for other volutids. The reproductive cycle of A. beckii in Mar del Plata was studied over a period of 2 yr (September 2004 to August 2006). Gametic emission in males continued throughout the year while females showed 2 spawning periods: one during spring (September-November) and another during autumn (March-April). In females, this semi-annual pattern appears to be related to the seasonal variation in seawater temperature, coinciding with observations made in other volutes. In males, there was no relationship to variation in seawater temperature, an unusual pattern for a species from a temperate region. Imposex was described for the first time in this species. These data constitute baseline information for establishing appropriate and biologically based management and conservation strategies for this overexploited gastropod species.KEY WORDS: Adelomelon beckii · Gametogenesis · Reproductive cycle · Volutidae · ImposexResale or republication not permitted without written consent of the publisher

“…In areas highly polluted with TBT, sterile females and population declines have been observed (Oehlmann et al, 2007). In Argentinean harbour areas, several gastropod species have been reported to be affected by imposex, including Buccinanops globulosus, and its congeners B. monilifer and B. cochlidium (Penchaszadeh et al, 2001, Bigatti et al, 2009, Averbuj & Penchaszadeh, 2010a. Pollutants such as TBT, heavy metals and polyaromatic hydrocarbons (PAHS) were detected in Nuevo Gulf at north Patagonia, Argentina (Gil et al, 2006, Massara Paletto et al, 2008, Bigatti et al, 2009.…”

Abstract:The aim of this work was to study the reproductive output and imposex parameters of the caenogastropod Buccinanops globulosus inhabiting a harbour area, with high maritime traffic and pollution. The results showed higher imposex incidence for non-gravid females than for gravid females (carrying egg capsules). Among imposex-affected females, mean penis size was significantly larger in non-gravid (3.4 mm) than gravid (1.5 mm) females. In B. globulosus usually a single juvenile hatches per egg capsule, but in this study capsules with multiple embryos were found. Overall, these results suggest a relationship between imposex development and alterations on the reproductive output of B. globulosus females living in adverse environmental conditions (polluted area).Key words: Maritime traffic, Offspring, Pollution, Reproduction, TBT.Resumen: El objetivo de este trabajo fue estudiar parámetros reproductivos y desarrollo de imposex en el caenogasterópodo Buccinanops globulosus que habita en una zona portuaria de alto tráfico marítimo y con presencia de contaminantes. Los resultados mostraron una mayor incidencia de imposex en hembras sin ovicápsulas que en hembras con ovicápsulas. Entre las hembras con imposex, el desarrollo del pene fue significativamente mayor en aquellas sin ovicápsulas (3.4 mm) que en las hembras con ovicápsulas (1,5 mm). En B. globulosus comúnmente un solo juvenil eclosiona por cada cápsula, sin embargo, en este estudio se registraron capsulas con múltiples embriones. Todos estos resultados sugieren una relación entre el desarrollo de imposex y alteraciones en los parámetros reproductivos de las hembras de B. globulosus que habitan en sitios con condiciones ambientales adversas (área contaminada).
