Reproduction, age, growth, feeding habits and population dynamics of four large temperate sharks (sand tiger shark Carcharias taurus, school shark Galeorhinus galeus, copper shark Carcharhinus brachyurus, and broadnose sevengill shark Notorynchus cepedianus) were studied in Anegada Bay (between 39°50' and 40°40'S), Argentina. Data were gathered from 1089 individuals examined during a three-year study period. Age and growth were studied through examination of vertebral centra only in the first three species. Population dynamics was modeled through stage matrix population models. Most sand tiger sharks examined were adults and evidence indicates that they use the study area as a mating ground. Sand tiger males mature at 193 and females at 223 cm total length (TL), which corresponds to ages of 4.5 and 7.7 years, respectively. Both sexes differed significantly in growth patterns. The population of sand tiger sharks appears to be stationary in the absence of human exploitation. When the mos.....
