Abstract

The Richibucto watershed covers approximately 1300 km2 and is located in New Brunswick, Canada. The Richibucto estuary and its associated river system have always played an important role in the lives of those communities that reside along its shores. Over the years many of the natural finfish and shellfish stocks have become jeopardized, and in some instances totally depleted. Increasing habitat destruction has resulted in significant portions of the estuary becoming permanently or conditionally-closed to shellfish aquaculture and harvesting. In 1996 the University of Moncton in collaboration with local communities and support from other scientists as well as government and voluntary organizations, undertook a major environmental study of the Richibucto waters. This multi-community investigation consisted of two phases: Phase1 identified factors that contributed towards the deterioration of the aquatic environment, proposed certain rehabilitative measures to address and correct problems and applied newly-gained information in helping to develop strategies that could contribute towards enhancement and aquaculture development of certain species. Phase 2, initiated in the spring of 2001, focuses on developing a thorough and integrated investigation of the economic carrying capacity of the Richibucto estuary for shellfish aquaculture. The latter is structured around four components: i. Oceanographic modeling, ii. shellfish farming at a commercial test site, iii. environmental health and iv. participatory coastal zone management. We anticipate that the program will contribute to long-term social, recreational and sustainable economic benefits for the residents of the area and ultimately serve as a model for other watersheds in Atlantic Canada.
