摘要

The relationships between changes in water temperature and the timing and level of reproductive investment were investigated in an estuarine fish, inhabiting the Venice lagoon: the grass goby Zoster-isessor ophiocephalus. A time series of the mean monthly values of gonado-somatic index was coupled with thermal profiles of lagoon water temperatures over 14 years, from 1997 to 2010. Results showed that the reproductive investment was positively affected by water temperature changes, both in terms of monthly thermal anomalies and cumulative degree days. A predictive model was also developed to assess the temporal shift of reproductive peaks as a response to inter-annual thermal fluctuations. This model allowed the detection of deviations from the median level, indicating that during warmer years, the reproductive peak tended to occur earlier than during colder years. The model is therefore proposed as a tool to predict anticipated consequences of climate change on fish phenology in transitional waters, regarding recurrent biological phenomena, such as reproduction and recruitment.
