The solid dot shows the median density (the middle value: half of the sites had equal or higher densities and half the sites had equal or lower densities). O’s mark rivers in which salmon were not captured. The box shows the inter-quartile range: half the sites had densities within this range. The whiskers (lines with square brackets) are drawn to the minimum and maximum densities observed each year. LGB supported rivers are where juvenile Atlantic salmon had been released since 1996. Densities outside the range of the graph are marked with an arrow. Rivers with blank spaces were not electrofished in those years (from Gibson et al. 2004). .

A Review of Ice and Tide Observations in the Bay of Fundy
A tlantic Geology 195 A review of ice and tide observations in the Bay of Fundy ConDesplanque1 and David J. Mossman2 127 Harding Avenue, Amherst, Nova Scotia B4H 2A8, Canada departm ent of Physics, Engineering and Geoscience, Mount Allison University, 67 York Street, Sackville, New Brunswick E4L 1E6, Canada Date Received April 27, 1998 Date Accepted December 15,1998 Vigorous quasi-equilibrium conditions characterize interactions between land and sea in macrotidal regions. Ephemeral on the scale of geologic time, estuaries around the Bay of Fundy progressively infill with sediments as eustatic sea level rises, forcing fringing salt marshes to form and reform at successively higher levels. Although closely linked to a regime of tides with large amplitude and strong tidal currents, salt marshes near the Bay of Fundy rarely experience overflow. Built up to a level about 1.2 m lower than the highest astronomical tide, only very large tides are able to cover the marshes with a significant depth of water. Peak tides arrive in sets at periods of 7 months, 4.53 years and 18.03 years. Consequently, for months on end, no tidal flooding of the marshes occurs. Most salt marshes are raised to the level of the average tide of the 18-year cycle. The number of tides that can exceed a certain elevation in any given year depends on whether the three main tide-generating factors peak at the same time. Marigrams constructed for the Shubenacadie and Cornwallis river estuaries, Nova Scotia, illustrate how the estuarine tidal wave is reshaped over its course, to form bores, and varies in its sediment-carrying and erosional capacity as a result of changing water-surface gradients.

Minas Basin, N.S
An examination of the population characteristics, movement patterns, and recreational fishing of striped bass (Morone saxatilis) in Minas Basin, N.S. during summer 2008 Report prepared for Minas Basin Pulp and Power Co. Ltd. Contributors: Jeremy E. Broome, Anna M. Redden, Michael J. Dadswell, Don Stewart and Karen Vaudry Acadia Center for Estuarine Research Acadia University Wolfville, NS B4P 2R6 June 2009 2 Executive Summary This striped bass study was initiated because of the known presence of both Shubenacadie River origin and migrant USA striped bass in the Minas Basin, the “threatened” species COSEWIC designation, the existence of a strong recreational fishery, and the potential for impacts on the population due to the operation of in- stream tidal energy technology in the area. Striped bass were sampled from Minas Basin through angling creel census during summer 2008. In total, 574 striped bass were sampled for length, weight, scales, and tissue. In addition, 529 were tagged with individually numbered spaghetti tags. Striped bass ranged in length from 20.7-90.6cm FL, with a mean fork length of 40.5cm. Data from FL(cm) and Wt(Kg) measurements determined a weight-length relationship: LOG(Wt) = 3.30LOG(FL)-5.58. Age frequency showed a range from 1-11 years. The mean age was 4.3 years, with 75% of bass sampled being within the Age 2-4 year class. Total mortality (Z) was estimated to be 0.60. Angling effort totalling 1732 rod hours was recorded from June to October, 2008, with an average 7 anglers fishing per tide. Catch per unit effort (Fish/Rod Hour) was determined to be 0.35, with peak landing periods indicating a relationship with the lunar cycle.

Cast) Smolt-To- Adult Supplementation (Sas) Experiment Proposal (Phase 1: 2018-2022)
Canadian Science Advisory Secretariat National Capital Region Science Advisory Report 2018/014 REVIEW OF RISKS AND BENEFITS OF COLLABORATION FOR ATLANTIC SALMON TOMORROW'S (CAST) SMOLT-TO- ADULT SUPPLEMENTATION (SAS) EXPERIMENT PROPOSAL (PHASE 1: 2018-2022) The Miramichi River in New Brunswick, Canada, highlighting the two main sub-watersheds associated with the SAS experiments. Figure Smolt-to-adult supplementation (SAS) in the life courtesy of the CAST SAS Experiment Proposal: cycle of Atlantic salmon Phase 1 (2018-2022) (Linnansaari et al. 2017). Context: Recent broad-scale declines in marine survival suggest that the most substantial threat(s) to wild Atlantic salmon in eastern Canada are found in the marine environment, and that the resulting high marine mortality is the primary constraint to the recovery of Atlantic salmon populations (COSEWIC 2010). Smolt-to-adult supplementation (SAS) has been proposed by Collaboration for Atlantic Salmon Tomorrow (CAST), a multi-stakeholder group, as an activity to circumvent low marine survival and to increase the number of spawners and freshwater juvenile production in the Northwest Miramichi River system (New Brunswick). SAS would be a precedent-setting activity for supplementation of Atlantic salmon populations in DFO’s Gulf region, where populations are showing decline but are not yet at immediate risk of extinction. CAST has developed a SAS Experiment Proposal with the goals of determining if SAS is a functional conservation strategy that can be used to supplement Atlantic salmon populations in situations where conservation objectives are not being met due to high at-sea mortality, and to answer identified scientific knowledge gaps regarding the SAS conservation strategy.
