This volume is a compilation of current research papers on the aquatic ecosystem of the Miramichi River in New Brunswick. The papers are organized in four sections: historical overview, the physical environment, the biological environment, and evaluating human impacts. Specific topics of the papers include the estuarine structure of the river, hydrology of the drainage basin, plankton, diadromous fish, estuary sediments, forestry impacts, and biological indicators. The volume also includes a summary and selected abstracts from the Miramichi Environmental Science Workshop held in Newcastle in 1994.

A catalogue that presents an inventory of 2214 species, subspecies and varieties, most of them named to the species level of metazoan invertebrates recorded from the Gulf of St Lawrence, the St Lawrence Estuary. It covers the Saguenay Fjord Benthic, Planktonic, nektonic and parasitic species and some salt-tolerant freshwater species.

Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.

An indexing, abstracting and document delivery service that covers current Canadian report literature of reference value from government and institutional sources.
