This book was released on 1998 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a study of the fork length, sex, and age of adult Atlantic salmon returning to the Nepisiguit River, New Brunswick. The study was conducted to determine whether those biological characteristics varied between fish of known hatchery origin (marked by a clipped fin) and presumed wild fish. Trends over time between 1982 and 1996 were also examined. Comparison is also made between the characteristics of Nepisiguit River salmon with those of the Miramichi and Restigouche rivers.

This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Available in PDF, EPUB and Kindle. Book excerpt: The Tabusintac River flows east into the Gulf of St. Lawrence in north-east New Brunswick. This report assesses the Atlantic salmon stock in the river in 1993, based on recreational catch estimates, a mark-recapture experiment to estimate population size & spawning requirement, measured biological characteristics, and estimates of total returns, spawning escapement, & egg deposition. The results indicate whether spawning targets for small & large salmon were met.
