Abstract
The holothurians have been overexploited in the Southwest region of Madagascar and
some measures have been established for a sustainable management. But ever since, very few
assessments of holothurian fishery have been made. From January to December 2018, we
performed an assessment of fishery activities (fishing effort, catches, processing and marketing
of products) and governance analysis at 3 main holothurian fishing villages (Sarodrano,
Ankiembe and Andrevo). Results showed that twelve species are collected by fishers in the
study area. Compared to previous studies, the catches increased but these are mainly composed
of Holothuria notabilis (88,73% of catches for Ankiembe, 79,53% for Sarodrano and 77,49%
for Andrevo) which have a low commercial value. Andrevo is significantly the most productive
village with 7734±7391 kg of fresh holothurians per month, followed by Sarodrano with
4296,96±2325 kg.month-1 and Ankiembe with 3846±2007 kg.month-1. Three forms of
holothurian commercial chains were identified involving fishermen, fishmonger and private
operators. Fishmonger or fishermen take care of part of the processing (evisceration, first
cooking, salting and second cooking), and the operators complete process to obtain exportable
trepang. Holothurian fishery in the Southwest Madagascar develops but some established
measures for their management and governance are not applied. Thus, it is recommended to
improve the aspects of the governance as well as to reinforce and to renew the system of
holothurian fishing management
