Available in PDF, EPUB and Kindle. Book excerpt: Reports assessments of Buctouche River (south-east New Brunswick) Atlantic salmon stock, as determined through mark-recapture experiments in which tags were applied in the estuary and recovered in the recreational fishery or at a counting fence upriver. Results of electroseining at ten sites during summer 1998 are included in the assessment, along with juvenile density data from previous years, for purposes of comparison. Information on biological characteristics such as length is also provided.

Available in PDF, EPUB and Kindle. Book excerpt: Due to egg depositions well below conservation requirements in recent years, the angling season was closed and there was no First Nation allocation of salmon on the Buctouche River in 1998. A mark-recapture experiment was the basis for estimating returns: tags were applied at two estuarial trapnets and recovered at a counting fence in freshwater. Total large salmon returns were estimated at 102 and total small salmon returns at 92. Respective spawning escapements were 101 and 91. Total egg deposition was only 33% of the conservation requirement, representing a 52% decrease relative to 1997. Juvenile densities at the sites surveyed were generally higher than previous years but still well below optimum, confirming that spawning in recent years has been inadequate. At present, sufficient information on stock status has not been accumulated to forecast returns, but an analysis of various management scenarios indicates that even with all fisheries closed, there is only a 1% probability that conservation requirements will be met on the Buctouche River in 1999.

Book Stock Status of Atlantic Salmon Salmo Salar in the Buctouche River and Relative Juvenile Abundance in Other Southeastern New Brunswick Rivers in 1999

Download or read book Stock Status of Atlantic Salmon Salmo Salar in the Buctouche River and Relative Juvenile Abundance in Other Southeastern New Brunswick Rivers in 1999 written by Gary Atkinson and published by . This book was released on 2000 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to egg depositions well below the conservation requirement in recent years, the angling season was closed and there was no First nation allocation of salmon on the Buctouche River as of 1998. Salmon returns in 1999 were calculated from catches and known efficiency of an estuary trapnet operated by Buctouche First Nation. Total large salmon returns were estimated at 244 and total small salmon returns at 114, with respective spawning escapements of 244 and 111. Total egg deposition was estimated at 102% of the conservation requirement. This represents a tripling of the level in 1998, and the first instance in seven assessed years when the requirement may have been met. Juvenile densities on the Buctouche were well below optimum, especially for fry, confirming the low egg deposition observed in 1998. Results from a juvenile survey of four other southeastern New Brunswick rivers indicated that the level of spawning success has been variable and asynchronous. The variability, unpredictability and generally depressed status observed in the Buctouche stock appears to be characteristic of most rivers in the area, and a valid basis for the general management of stocks. The forecast for the Buctouche in 2000 is five year mean of total returns, which is 167 large and 106 for small salmon. With all retention fisheries closed there is only a 3% probability that the egg conservation requirement will be met in 2000.

Book Status of Rocky and Little Rivers Atlantic Salmon Salmo Salar L Stocks of the Newfoundland Region in 1998

Download or read book Status of Rocky and Little Rivers Atlantic Salmon Salmo Salar L Stocks of the Newfoundland Region in 1998 written by and published by . This book was released on 1999 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two watersheds in Newfoundland discussed in this paper have all undergone Atlantic salmon enhancement or stocking activities. Rocky River on the Avalon Peninsula was the site of a colonization project where a run of Atlantic salmon was established. Little River, which flows into the Bay d'Espoir, is the site of an ongoing ranching project with associated fry stocking. The intent of this document is to review the status of Atlantic salmon stocks in the two watersheds in 1998. Information is included on watershed characteristics, conservation requirements, enhancement/stocking activities, management restrictions, salmon fecundity, egg depositions, smolt counts, smolt to adult survival, egg to smolt survival, parr rearing, and predicted versus observed adult returns.
