Sightings 2011 - 2013
Since the Kenya Marine Mammal Network
was established in May 2011 until September
2013 a total of 681 sightings were reported
from 45 collaborators.
Figure 1 and 2 — A total of 681 sightings reported from May 2011 to
September 2013. Below, the endangered IP humpback dolphin, a mother
and calf.
The reports came from Shimoni (South coast) to Watamu (North coast) and the most sighted locations
were: Watamu-Malindi ( 364 sightings ) and Kwale
(305). A total of 12 cetacean species were spotted,
being the Indo-Pacific Bottlenose Dolphin and Humpback Whale the most sighted species (Fig. 1). Based
on the IUCN Red List of Threatened Species, six of
these species are classified as “Data deficient”, three
as “Least concern”, one as “Near Threatened” and
two as “Vulnerable” (http://www.iucnredlist.org/).
It is important to notice that although high diversity of marine mammal species were seen
along the coast, very few sightings were reported for the endangered IP humpback dolphin. Only 27 sighting in three years. And
most of them on the south coast.

Sightings 2011 - 2013
As the network expands, it will help to monitor
marine mammal populations and create an
opportunity for anyone to contribute directly to
cetacean research, appreciate and learn about
marine mammals and their environment.

the Kenya coast (2011-2013)
Figure 2 - IP bottlenose dolphin distribution.
The IP bottlenose dolphin was mainly reported
around the Marine Protected Areas (KisiteMpunguti and Watamu-Malindi MPA), which
these animals use for socializing, feeding and
resting. It is probable that the offshore sightings belong to the common bottlenose dolphin
species, which has a preference for deeper
waters.
Humpback whales were seen on their migration through Kisite and Watamu. High
numbers of animals were reported by deep
sea fishermen on the Watamu Banks (71
sightings) and around “The Rips” (14 sightings).

At least 100 resident Bottlenose Dolphins
in the Watamu Marine Protected Area
The development of Watamu Marine Association’s Indo-Pacific Bottlenose Dolphin photo-identification catalogue is nearing its final
stages of completion after more than 7 months, during which time more
than 4000 photographs of dorsal fins were analysed. These photographs
comprised several research seasons from 2010 to 2012.
Jane Spilsbury and
Emmanuelle Leveque
take photograhs of
the dolphin’s dorsal
fins for identification
of individuals.
Photo-identification remains the primary tool in mark-recapture analysis and the basis upon which all further research is conducted when studying cetacean populations. Each dorsal fin on a bottlenose dolphin is as unique as a human’s fingerprint.
Identifying individuals means that an individual’s sex, health status, habitat usage
and social interactions can be tracked over long periods of time.
The catalogue was developed as part of a continued expertise exchange
and collaborative exercise between Kenya Marine Mammal Network
(KMMN) partners GVI and WMA.
Originally thought to have
around 80 resident bottlenose
dolphins, the development of a
new improved catalogue has revealed that there are more residents than previously thought.
With 100 dolphins identified, and more yet to be
added, this catalogue is an
exciting new addition of
resources to the WMA dolphin research team.

Amazing Humpback whale Season 2013!
As the Humpback Whale migration season started this year, reports from fishermen came
flooding in from July through to October in the Watamu National Marine Protected Reserve.
The local dingy fishermen who brave the ocean in the Kusi monsoon season kept a careful eye out for the
whales which travel north from the Antarctic to breed and give birth and were rewarded by sightings of 1
to 25 humpback whales per day. With almost 80 reports from the local fishermen alone (not counting the
sports fishermen reports) this was an exceptional year, with everyone declaring that they had never seen so
many whales in Watamu, since they were first noticed 16 years ago.
The Watamu Marine Association whale hotline was almost off the hook, especially during July and August,
and on East Africa’s Synchronized Whale Watching Day when WMA had reports of 38 animals . With reports of very young calves and mothers, also it seems that Watamu is a safe haven for
humpback whales.
To thank and celebrate the faces behind
the whale reports -Watamu Marine Association presented certificates and t
shirts to the reporting crews. We give
thanks to these fishermen who are contributing to the national KMMN database
and helping with marine mammal conservation. Including Mohamed Athman,
Hassan Makame, Mohamed Omar, Ishmail Athman, and Feiswal Lali plus coordinators Athman Abdalah and Michael
Gilbert Mwang’mbe.

New discoveries on the humpback dolphin
populations along the Western Indian Ocean
According to the study published by Dr. Martín Mendez (Wildlife Conservation
Society/American Museum of Natural History) in Molecular Ecology – which
looked at the dolphins’ physical features (including over 180 skulls) as well as
their mitochondrial and nuclear DNA (235 samples) – the world’s humpback
dolphins should be split into four distinct species: the Atlantic humpback dolphins (Sousa teuszii) found off the coast of West Africa; Sousa plumbea found
in the western and central Indian Ocean; Sousa chinesis found in the
eastern Indian and western Pacific Oceans; and the new species off the coast of
Australia (Fig. 1)
Humpback dolphins
– named for a peculiar
hump just below the
dorsal fin – belong to the
dolphin genus Sousa.
These animals measure
from 1.8 to 2.6 meters in
length and range from
dark gray to pink or
white in color. They are
found along the west
coast of Africa throughout the Indian and Pacific oceans to the coasts
of Australia.
Humpback dolphins are considered ‘vulnerable’ (S. teuszii) and ‘near threatened’ (S. chinensis), both with decreasing population trends in the IUCN Red List . However, S. chinesis comes close to qualifying for vulnerable
and should be reassessed following a taxonomic assessment of the genus, especially considering the implications
of S. chinensis potentially being subdivided into multiple species. Moreover, recent population-level analyses of
mtDNA control region data uncovered further variation within S. plumbea in the form of significant genetic
structure between the populations in Oman - Tanzania and an assemblage formed by South Africa and Mozambique due to environmental boundaries (Mendez et al. 2011)
Based on this information, it is important to study the number of humpback dolphins remaining
in Kenya. So far, GVI has a photo-id catalogue for humpback dolphins with only 30 individuals.
And over the 8 years that GVI has been studying marine mammals in Kisite-Mpunguti Marine
Protected Area, the number of humpback dolphin sightings has decreased over the years. Dr.
Martín Mendez also highlights the importance of studying this population on his article, “we suggest that attention also be paid to the evolutionary and ecological uniqueness of populations that are clearly divergent, such
as those in the central and western Indian Ocean. To continue filling taxonomic gaps of Sousa in this geographical region, we recommend increased and targeted sampling efforts and additional analyses of multiple lines of evidence of their evolutionary uniqueness”

evidence to better understand the evolutionary divergence of
humpback dolphins along their entire distribution range: a new
dolphin species in Australian waters?." Molecular ecology (2013).

KMMN photos
Humpback whales were the stars this season! The first
sightings arrived in July and until November we had
regular reports from these amazing animals all along
the Kenya coast. They featured in an article from the
latest SWARA - East African Wild Life Society quarterly
magazine on the recent humpback whale migration
and sightings along the East Africa coastline. These
spectacular photos show how they breached spectacularly out of the water. On the bottom (left) a bottlenose dolphin feeds on a scrawled file fish (Aluterus
scriptus) in Kisiti Mpunguti MPA and we had our very
first report of a Dwarf Minke Whale (Balaenoptera
acutorostrata subsp.)

Land-based studies in Watamu
Do you want to join us in Whale Research? Spot Humpback Whales from
the Shore in Watamu was the call from The Watamu Marine Association this
July. Watamu piloted the first ever land based surveys with volunteers from a number of
conservation organisations including Local Ocean Trust and A Rocha Kenya in Watamu.
A volunteer participates in the new
Watamu Land Based
Survey Program.
If anyone is interested
in
whale
watching tours on
the ocean in 2014 –
please contact Hemingways
Using methods adapted from the East African Team led by Dr Matt Richmond the surveys
were a great success. Situated on Kiluli Island in the Marine Park this 20 metre high vantage point offers 180 degrees vision south and north of the Park. During twice weekly
surveys the whale research teams spotted up to 7 whales per survey breaching and performing tail up dives. Whales are frequently sighted off Watamu’s shores by visitors and
residents. It is thought that the whales travel close to shore as the inland tropical reefs
protect young whales and mothers vulnerable to predators in the open ocean which is
ideal for scientific surveys. Following the success of the WMA pilot study, African Fund
for Endangered Wildlife are supporting Kenyan students who will collect data in a
new Watamu Land Based Survey Program in 2014 during next years migration.
Watamu Marine Association wishes to thank all the participants in the WMA Whale
Research Project including Richard Bennett, resident marine biologist, for his regular
land reports from the Blue Lagoon Headland, plus recruiting the local children. Also
special thanks to Thomas Achira of Kwanza Estates who provided the perfect land based
viewing site on Kilulu island. Also worthy of note is that Hassan Makame and star
reporter, reported 3 whale sharks (the largest fish) out of season and predicts an increase
in numbers of these animals which have reduced in recent years.

GVI Participates in the East Africa Synchronised Whale
Watching Day 2013
As part of GVI’s continuing commitment towards collaborative efforts and
support of other cetacean research initiatives, the marine team once again
this year took part in the Synchronised Whale Watching Day
(SWWD) on the 10th August, organised by the East Africa Humpback Whale Network. The collaborative effort aims to gain an accurate count and idea of distribution of humpback whales along the entire
eastern edge of the African continent in order to identify population abundance and migration routes.
The weather was on the whale spotters side. The day dawned clear with a
light breeze and almost dead calm sea conditions. Participants everywhere turned their eyes to the ocean to attempt to sight the humpback
whale, a seasonal visitor to Kenya’s coastline. The GVI team took advantage of such favourable conditions and
extended the survey day in order to get the best count of humpback whales possible. The 7.5 hour boat survey
covered a huge amount of water off the edge of the continental slope, from Funzi Bay, past Nyuli Reef and Upper
Mpunguti towards the Mako Kokwe reef at the very edge of the Kisite-Mpunguti Marine Protected Area.
Over the course of the day, the team sighted several splashes on the horizon, potentially indicating at least three whales about 15km offshore. Late in the morning two adult whales, were sighted
off Upper Mpunguti, heading into deeper waters. Most of the survey area remained clear of whales until the very
end of the day, when two whales were sighted by their blows off Nyuli Reef. Overall, it was a successful day,
with a maximum count of 7 whales on Kenya’s south coast, and a conservative count of 4.

Interview with Dr. Bernerd Fulanda
Dr. Fulanda is a Kenyan Fisheries Scientist & Marine Ecologist by training. Holds a B.Sc.
(Fisheries) -MOI University, Kenya; M.Sc. (Environmental Sciences) from the UNESCO-IHE, DelftThe Netherlands; M.Sc. (Fisheries & Oceanography), Kagoshima University and a Ph.D (Marine
Resource Science - fisheries). He has worked in the State Department of Fisheries as Fisheries
Officer (Research & Development) (1997-2000); and then at the National Aquaculture Development and Training Centre (2000-2004) before joining the Kenya Marine & Fisheries Research
Institute as a Research Scientist under the fisheries program (2005-2013). In October 2013 he
joined Pwani University as a lecturer in the Department of Biological Sciences, School of Pure and Applied Sciences. His
association with the KMFRI still remains strong with collaborations in marine and fisheries research, student internships, workshops and training in coastal and marine resource management and aquatic sciences.
“Such an approach
(KMMN) can
therefore avail
data over several
decades,
sustainably, with
minimal costs.
The KMMN
therefore
remains a very
crucial partner in
the effort to
conserve and
manage our
marine and
coastal resources
especially in the
recreational
sector including
tourism. “
1 - What do you think about the Kenya Marine Mammal Network?
First and foremost, the KMMN presents an important forum for collection and sharing of data on the marine
mammal species within Kenya and Indian Ocean waters of the Eastern coast of Africa whose populations
have greatly fluctuated with some species under serious threat of fishery by-catch, marine pollution and
habitat degradation and other activities including tourism associated damage.
Secondly, the network depends on indirect research approaches to collect data including opportunistic species
data collection from non-scientific vessels and individuals who regularly frequent the waters where the
marine mammals occur, presenting a great opportunity for data collection especially in resource-poor
nations such as Kenya where financing of research remains low. Such an approach can therefore avail
data over several decades, sustainably, with minimal costs. The KMMN therefore remains a very crucial
partner in the effort to conserve and manage our marine and coastal resources especially in the recreational sector including tourism.
2- How were the KMFRI surveys around Ungwana Bay where marine mammal data was collected?
The Kenya Marine and Fisheries Research Institute conducts various studies within the Malindi-Ungwana Bay
using leased vessels or by deployment of observers onboard the commercial fishing vessels operating
within the bay, notably the bottom prawn trawlers and the small and medium pelagic fishery fishing
vessels including purse seiners. Over the last decade, KMFRI has been lucky to have two fisheries research
projects within the coastal and marine waters of Kenya: the just concluded SWIOPF and the currently
running KCDP project. In these surveys, the focus has been on assessment of the levels of target catch, bycatch as well as the occurrence of marine turtles and cetaceans including dolphins in bycatch from the
Malindi-Ungwana Bay fishing grounds. Additionally, data on sighting of marine cetaceans, referencing of
the sighting location etc. is continuously recorded during the surveys, although specific data on e.g. cetacean behaviour, characteristics etc. may be lacking due to shortage of trained scientists on cetacean behaviour and habits within the feeding grounds.

3- What is KMFRI doing towards marine mammal conservation?
KMFRI is a state corporation whose mission is to contribute to the management and sustainable exploitation of aquatic resources through multidisciplinary and collaborative research in both marine and fresh-water aquatic systems. In its effort to contribute to the conservation of marine mammals as well as enhance sustainable exploitation of the coastal and marine resources, KMFRI conducts extensive studies on ecology and conservation of endangered marine species (turtles, mammals, sharks, seabirds) through the KMFRI Fisheries, and the Marine Environment and Ecology
Programs and, together with the State Department of Fisheries.
4-Are you involved on any other marine mammal project?
Although not actively involved on a daily engagement, I work closely with the other organization which providing research space for our undergraduate and graduate students in the Coastal & Marine Resource Management (CMRM) Course)- KU Mombasa Campus, and the Pwani University
Marine Biology & Fisheries programs. Our collaborating organizations include the Watamu Marine Association (WMA), the Watamu Turtle Watch
(WTW) and various private ventures including the Sport fishing companies and Community Marine Conservation initiatives and CBOs.
Interview with Dr. Nina Wambiji
Dr. Nina Wambiji is a Research Officer at Kenya Marine and Fisheries Research Institute (KMFRI), Mombasa, Kenya.
She holds a Ph.D in Marine Environmental Sciences (Fish Physiology) from the University of the Ryukyus-OkinawaJapan. She is interested in fish ecology and physiology, marine invertebrates and developed a passion for dolphins
when she was a research Assistant in the MASMA Sustainable Dolphin Tourism in East Africa project, conducting boat
based surveys on distribution, behaviour and abundance of dolphins in Kizimkazi area-Menai bay, Zanzibar in 2005.
Currently she is the Marine mammal contact person for KMFRI. This involves receiving stranding and bycatch reports,
and participating in awareness and education.
1- Why is it important to protect marine mammals?
They are beautiful creatures that take long to develop or reproduce. They do not occur everywhere thus wherever they
are sighted and noted to be resistant, sanctuaries or total protection of that area should be ensured. The survival rates
can be hampered if humans do not check their impacts through anthropogenic activities. I think KMMN is a good initiative that when owned by all stakeholders will lead to the conservation of our marine mammals. It creates awareness to
the Kenyan masses on the beautiful marine resources that we have and also to the outside world on what Kenya has to
offer for interested marine researchers, tourists and conservationists.
“It creates awareness
2. How is the fisheries-marine mammal interaction along the Kenyan coast?
I think it occurs in some areas and we may not have the data to confirm this. I also think for the migratory species this
is possible.
3. What is the involvement of KMFRI with the Kenya Marine Mammal Network?
KMFRI and I specifically, is interested in creation of awareness of our magnificent marine mammals to the Kenyan people. KMFRI as an institution can partner with KMMN to do some research, analyze available data, publish and create
awareness to a wider audience.
to the Kenyan
masses on the
beautiful marine
resources that we
have and also to
the outside world
on what Kenya has
to offer for
interested marine
researchers,
tourists and
conservationists.“
4. Have you ever participated in other marine mammal projects?
Yes, I have participated in the Menai Bay dolphin project in Zanzibar and I created links with GVI when they first came to Kenya.
Thank you both for your collaboration!
