Abstract

This study was conducted to estimate the carrying capacity and population growth pattern of lola snail (Trochus niloticus) in Saparua Island. Samples were collected by strip transect method which was 100 meter long and 2 meter wide and were laid perpendicular to the coast line starting from the lowest tide level. Data were analyzed by Bhattacharya method to determine the age classes each individuals. The results showed that the population density was 620 individual/ha and the net reproductive rate of lola was 226 individuals and generation time was 2.88 years. Based on these this results, the carrying capacity which is the theoritical maximum density of lola snail population can be estimated to be 27.779 individuals per hectare and its population growth can be described by equation Nt = 27,779/e4.232-.,884. On the other hand the optimum population growth would be obtained when the population density equalled to 13.890 individuals in 2.25 years.
