Monitoring The Health Of Kenya’s Reefs

My name is Aaron. I am a conservation student from England. I have joined Global Vision International (GVI) as a conservation intern to gain experience in the marine biology field. I have been with GVI for 9 weeks with a further 11 weeks to go.
This week on Marine represented a new opportunity to expand GVI’s research in Kenya. The majority of GVI’s marine research has concentrated on monitoring tourist and fishing activity against dolphin behavior and abundance. Whilst this research has been, and continues to provide essential data to Kenya Wildlife Service, it is only focused on the effects to cetaceans.

Setting up the survey

This week we were able to begin monitoring reef fish abundance, with the intention of creating a long term data capture, similar to that of the dolphin surveys. This means that not only will we be able to see effects of tourism and fishing on dolphins, but we will also be able to see the effects on not only reef fish, but also coral reef habitats as the abundance of reef fish can indicate the health of reef habitats, which also act as feeding grounds for dolphins.

The way reef fish surveys are done is by sampling 5 random sections of coral reef habitats. Reef fish species and size are noted down. This gives a snapshot of the reef fish abundance at any one point in time and provides data on an exciting and important aspect of the marine ecology of Kisite-Mpunguti Marine Protected Area. It’s an honour to help set up this research and I am proud to be contributing to something that can make a real difference.

Dugongs are back on Kenya’s south coast

Before we move completely in to a new and exciting of year of GVI and Kenya, some of our research and community development team have put together their highlights and memories of the end of last year to share. So, from the research boat, Bardan…

Not forgetting the beautiful humpback whales, including their calves, that we saw and blogged during our first couple of weeks on the marine research programme back in October, the rest was equally exciting. On many occasions we could count ourselves lucky enough to spend time in the wake of large groups of Indian Ocean bottlenose dolphins… the coolest part though? Thanks to a lot of office time and more photographs of fins than we care to dwell on, we could recognise many of the dolphins and know them by name! Mothers, juveniles, calves all leaped from the water demonstrating elegance and playfulness in equal measure.

Indo-pacific humpback dolphins also put in an appearance but remarkably… and for the first time ever… the cetaceans (our whales and dolphins) were upstaged by another marine mammal. And one that we never truly, honestly expected to see, however much we had hoped. On 4th November 2008, our dedicated observers on board Bardan, whilst tracking bottlenose dolphins in to Funzi bay, recorded the first confirmed sighting of a dugong on Kenya’s south coast in the three years we have been here, and to our knowledge, in over a decade; none were recorded south of Mombasa in a 1998 aerial survey, whilst Kenya’s entire population, concentrated around the Lamu archipelago, could be down to single figures by now.
