Impact of Climate change Variability on Abundance of Crab in Pangani Estuary

This research proposal focuses on the impact of climate change on abundance of mud crab (Scylla serrata) in the wild stock. Crab farming is practiced by collecting seeds from the wild and then shorten their growth period by fattening. Mud crabs are highly valued for their size, high meat yield and the delicate flavor of their flesh. Climate change is anticipated to alter some conditions in marine habitat and affect the growth performance of water organisms including mud crab. The associations between mud crab population and climate change have not yet been described along the Tanzanian coast. Lack of accurate and precise information of the mud crab abundance and its distribution signifies the need for further research. Results of the study will guide the development of sustainable methods of exploiting this marine resource.
Ce projet de recherche se concentre sur l’impact du changement climatique sur l’abondance du crabe de boue (Scylla serrata) dans le stock sauvage. L’élevage des crabes est pratiqué par la collecte des semences dans la nature, puis on raccourcit leur période de croissance par l’engraissement. Les crabes de boue sont très appréciés pour leur taille, le haut rendement en viande et la saveur délicate de leur chair. Le changement climatique est prévu de modifier certaines conditions de l’habitat marin et d’affecter les performances de croissance des organismes aquatiques, y compris du crabe de boue. Les associations entre la population de crabes de boue et le changement climatique n’ont pas encore été décrites le long de la côte tanzanienne. Le manque d’information exacte et précise de l’abondance des crabes de boue et de leur distribution signifie la nécessité de poursuivre les recherches. Les résultats de l’étude orienteront le développement de méthodes durables d’exploitation de cette ressource marine.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Risk and Vulnerability
