Abstract:
Krakal Beach Yogyakarta was the most disturbed beach among others in Yogyakarta in term of shells exploitation. Those shells had been traded not only locally at Krakal Beach, but also to Kukup Beach, Baron Beach,Yogyakarta city and for export purpose in the form of raw or handicraft material. Those activities makes the beach condition even much worse.
Some researches were done to reveal whether exploitations were done by tourists (Andiet al. 2005) or local people (Zahidaet al. 2005), and the researched showed that it caused by local people. Further research wanted to elucidate the intensity and volume of harvested shells (Zahida and Sinulingga 2004), and the results showed that more shells were harvested before adults. This was an indication of overharvesting.
Overharvesting or commonly called as overfishing status of the shells exploitation was studied in Krakal Beach, Yogyakarta. King (2003) stated that the exploitation of gastropods for their shells is unquantified, but may account for a much larger live catch weight than does exploitation for food. The aim of this research was to study the density and reproductive pattern of R. sinensis from Krakal Beach, Yogyakarta.
