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.

This book was released on 2004 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1974, a spot-check electrofishing survey was conducted to determine the extent of juvenile Atlantic salmon populations in south-east New Brunswick rivers. Subsequent electrofishing, conducted quantitatively in varying years up to 2003, focussed on the Kouchibouguac, Couchibougacis, Richibucto, Coal Branch, Buctouche, and Cocagne rivers as having the greatest potential for salmon production in the south-east region. The Buctouche also served as an index river for the status of Atlantic salmon stocks from 1993 to 2002. This report presents abundance indices and other relevant data for all species collected in these surveys. For juvenile Atlantic salmon in particular, the results are discussed with respect to ecological factors and currently-used assessment reference points.

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.
