THE IMPACT OF ECOTOURISM ON FISH DIVERSITY IN KAMUNI CREEK, GUYANA

Aims: To assess the impact of ecotourism on the Ichthyofaunal diversity in Kamuni Creek, Demerara River, Guyana.

Study Design: Semi-structured interviews and fish surveys were used to examine the variants for the study.

Place and Duration of Study: The study focused on areas that were frequently exposed to tourist activity, which included the Amerindian village of ‘Santa Mission’, located in Kamuni Creek, Demerara River, Guyana. Data was collected from May 5 to June 9, 2013.

Methodology: Twenty semi-structured interviews were conducted to understand the anthropological activities associated with Kamuni Creek and to determine whether these activities directly affected the fish diversity. Fish sampling was conducted in three disturbed and three undisturbed sites along Kamuni Creek to assess fish diversity. Various methods were used to collect fish samples which were photographed for identification. At each site, water pH, temperature and dissolved oxygen content were measured.

Results: The results indicated that although fish was a main food source for the people of Santa Mission, there was no commercial fishing. Ecotourism activity increased after the establishment of an Ecotourism Resort in close proximity to the village. There was an increase in the freshwater tropical cichlid (Heros severus). However, the Cichla ocellaris population, a once prominent species found in the area, decreased due to habitat and nesting ground degradation. Ecotourism does not directly influence fish population, since sport fishing was not offered by the resort(s) and there was signs along the creek that notified persons that fishing was prohibited. However, the increased presence of humans throughout the creek and the more prevalent use of motor boats have disturbed fish populations.

Conclusion: Ecotourism did not appear to have a negative effect on fish population. The ichthyofaunal population should be monitored, through routine or random investigation, to ensure sustainable practices are maintained.
