Numerous studies have been carried out throughout the world to access the impact that boat activity has on the behavior of bottlenose dolphins.  These include locations such as Clearwater (Florida), Hilton Head Island (South Carolina), Shark Bay (Australia) and off the south coast of Zanzibar.  The studies have come to show that various boating activities do have an impact on dolphin behavior such as causing changes in activity, movement and dive patterns.  They have also proven that the abundance of dolphins present in a pre-selected site has been negatively affected with such activity.

GVI have recently introduced a new survey to the marine programme in which we will investigate the effect of boat interactions with Indo-Pacific bottlenose dolphins within the Kisite-Mpunguti Marine Park, Kenya.  The methodology adopted by GVI is the same as that used in Zanzibar, in which they investigated the behavioural changes of Indo-Pacific bottlenose dolphins in response to boat-based tourism.  In order to do this GVI devised a data sheet to capture two sets of information.  The first relating to the number of tourist dhows present, the distance they are from the group of dolphins and whether they violate the guidelines and secondly to record the behavior of the dolphin group; activity, spread within party, movement, dive type, party speed and direction.

The behavior and associated data of the dolphins is sampled every fifteen minutes using focal-group scan sampling.  To do this all individuals within the group are continuously scanned for the first five minutes (ensuring at least three scans), and the dominant behavior is determined and recorded.  The dominant behavior is that which more than half of the group are engaged in at the sample time.  The remaining ten minutes of a sample period, referred to as the lag-phase, is used only to record the number of tourist dhows within a distance of less than 50m from the dolphin group and to indicate whether they are violating the guidelines.  This process is repeated every fifteen minutes for as long as possible. 
The behavioural studies are part of the Socio-economic impact of the dolphin-watching industry in Kisite-Mpunguti Marine Protected Area project. The objectives of this project are to collect information about the socio-economic impact of tourism operation on the area and to analyze the sustainability of increased levels of human-dolphin interaction.

The activity of dolphin (whale)-watching is described as “the commercial observation of cetaceans in their habitat from a platform on land, sea or air” (Hoyt 2001).
The dolphin-watching industry constitutes an emergent business in many coastal areas around the world and has seen spectacular growth over the last fifteen years. The industry began in the 1950’s in San Diego (California) and has since expanded as far as Antarctica. During the 1960’s, the industry grew significantly in the United States and Canada, followed by Australia, New Zealand, the Canary Islands, Japan and Norway in the 1980’s (Hoyt 1995, 1996) and, Iceland, Philippines, Indonesia, Hong Kong and Tonga in the middle of 1990’s.

 
In 1998, the number of dolphin-watching tourists totalled around 9 million, estimating the volume of income generated to be 1 billion US Dollars, doubling the income in 1994 (Hoyt, 2001). In 1998, of those nine million participating in dolphin-watching trips, one million were from the United States alone. More recently, other countries and regions such as the Canary Islands and Canada have reached similar volumes. Australia and South Africa are expected to double their numbers from 500,000. (Hoyt, 2001)
This activity has been developed in more than 492 communities with the majority experiencing a real transformation. Dolphin-watching provides important incomes, creates new activities which generate new employment and moreover, constitutes a very useful tool to study marine mammals and marine environments.
Whale and dolphin watching have become an increasingly popular and financially important tourist activity along the East African coast.  Currently, dolphin research and conservation efforts are being undertaken in Tanzania (Zanzibar) and Mozambique within the Sustainable Dolphin Tourism in East Africa Project. However, to date, few studies of cetaceans have been undertaken in Kenya and there is an urgent need to initiate research to aid future conservation and management of the species found in Kenyan coastal waters.

A bottlenose dolphin being watched by tourists in the KMMPA 
Global Vision International (GVI) Kenya has set up a new project focused on the dolphin-watching activity of Kisite-Mpunguti Marine Protected Area (KMMPA). The objectives of this project are to collect information about the socio-economic impact of tourism operation on the area and to analyze the sustainability of increased levels of human-dolphin interaction.  Further, to identify existing problems and to propose constructive changes to respective government institutions that would help boat operators, tour companies, and the local residents in running the activity sustainably. These objectives will in turn add value to the Code of Conduct for KMMPA, developed by Kenya Wildlife Service in 2007.
Aims:
 1. Analysis of the socio-economic activity (dolphin-watching) in KMMPA.
 2. Impact of tourist dhow boats on the cetacean population.
 3. Education and awareness of boat operators and tour guides.

The data will be collected through interviews to tourist, boat operators, hoteliers and local community members in Mkwiro, Shimoni and Wasini. Also, GVI research vessel will assess the impact of this tourism investigating the abundance, distribution and behaviour of Indo-Pacific bottlenose dolphins (Tursiops aduncus). Moreover, we will compare sightings and behaviour on different areas and with different levels of tourism activity that will allow us to evaluate the Code of Conduct. And finally, GVI will create awareness and education of local dolphin species and habitats engaging the boat operators and tour guides in different projects so as to promote conservation issues.
