Moidjio C.R.C.A.D. | Whale & Dolphin Watching

Moidjio C.R.C.A.D.

Moidjio CRCAD is a non profit organisation who welcome people to help for conservation of marine mammals and turltes. 

Moheli and the marine park is one of the best destination in the world with more than 9 species of whales, 9 species of dolphins, Dugong and marine turtles. 

Make your whales watching experience a donation to conservation, your help is needed and you'll have the trip of your life.

The project (5 years): 

This project aims to answer to the I.W.C scientific committee call for research in the area. We would like to focus the research on population identification and abundance estimation as well as breeding stock structure and behaviour assessment. It is also planned to undertake a stock assessment of other marine mammals encountered during assessment, such as Dugong, dolphin species and other whales. All our results will be used for law reinforcement within the marine park of Moheli in order to protect and conserve effectively marine mammals. We will also monitor Dugong habitat for best management practice.

The project is the first ever complete study in the area, bringing new concepts and expectations to local conservation effort, aiming to make new discovery in the area, testing a combination of survey effort techniques for population estimation and trends, understanding breeding behaviour and gender disparity, working on and adapting statistical models and reinforcing law within the marine reserves. The 2008 I.W.C. Workshop urged scientist community to work on different humpback whales Breeding Stock (BS) with priority given, among others, to BSC including Comoros islands.

Humpback whale research is indeed very poor in the Comoros but nevertheless promising. This reflects the lack of economical development and scientists’ availability, especially for the three independent islands. This whale population is of great interest for research because as well as being understudied, it is fairly undisturbed by whale watching, vessel traffic and fishery gears around Comoros, giving scope for behavioural observations. The monitoring of Dugong habitat is paramount in any conservation effort and easy to put in place it is also possible to either spot them or traces of their feeding behaviour. Dugongs are nearly extinct in Comoros and recording sign of recovery would be of great scientific interest.

What is photo identification ?
We are using a Canon 40D and a Canon 50D using a 300mm and 200 mm optical lens to shoot whales and dolphins. To be competent on photo-ID, you have to be very confident with your camera and know it well. Here, we are trying to recognise the whale or dolphins years after years by using natural marking. It is a very reliable and non invasive method of  monitoring cetaceans populations. According to the species there are points of interest that we will focus on. 
For  humpback whales, we are looking at getting the fluke which is the best and easiest way to recognise individuals and after the dorsal fins 2 sides,  pectorals if we can and finally any really obvious marking such as scares or discolouration, dimorphism.

For dolphins we are looking at the dorsal fin which present different designs, shapes and scars and then we are processing the data into Darwin 2.0 software. 

Basically we are looking to get as much clues as possible, to make the best identification.  Once done, the pictures are loaded into computers and we try to match them to previous encounters. Each Whale get a name, an ID number and we are recording date, time, position, behaviour, group size and presence of calves. 

 For each encounter, a GPS point is recorded and every 15 minutes, in order to localise preferential habitat. 

 An identification card is also dressed for each individual and matching pictures are grouped together to understand  how long whales are staying for and if they come back years after years and for long studies how long they live, how many calves they had etc...

Acoustic Surveys

Behavioural study? 
We are looking at several aspect of whales and dolphins behaviour. We are focusing on whale watching impact on direct behaviour of cetaceans population in order to advise in tourism best practice. You will be in charge of taking notes in order to record whales and dolphins' surfacing, change of direction, distance boat-pod, distance between individuals.
