“…Average and standard deviation (SD) of length by week were calculated. Growth analysis was made using VON BERTALANFFY's model (1938), which has been widely applied for gastropods (LOREAU & BALUKU, 1987;ITUARTE, 1989ITUARTE, , 1994RUMI et al, 2007;GUTIÉRREZ-GREGORIC et al, 2010). This model is described by the equation L t = L (1 -e -k t ) (where: Lt = shell length at time t, L = maximum calculated (theoretic) shell length and k = growth constant).…”

“…In the Cantera Grande Lake, located at the southern end of the Martín García Island, this species was also abundant during the summer and fall of 1995 (Rumi et al, 2004). Ituarte (1989) observed the unimodal characteristic of the growth curves of populations of Biomphalaria straminea (Dunker, 1848). We conclude that unimodality and only a single reproductive period of a given species are distinctive characteristics of the ecology of the Planorbidae family.…”

“…Balandra produce en C. fluminea una estacionalidad en el ciclo reproductivo, el cual se concentra en los meses de invierno y no en verano o primavera-otoño como el resto de las familias de gasterópodos (Ituarte, 1989(Ituarte, , 1994Martín, 2001;Rumi et al, 2007). Este es un punto muy interesante, ya que la mayor abundancia y riqueza específica de esta familia se concentra en la patagonia argentina, en donde las temperaturas son relativamente bajas la mayor parte del año.…”

“…straminea (Dunker, 1848) también se reproducen por lo menos dos veces al año, ninguna de ellas en invierno (Ituarte, 1989(Ituarte, , 1994. Chilina megastoma, que habita también un ambiente subtropical respeta esta tendencia de varias cohortes a lo largo del año, con la particularidad de poseer cohortes de invierno, tendencia que presentan también C. fluminea.…”
