Since 1976 there have been 14 confirmed occurrences of coho salmon, involving 1-22 individuals, in the Bay of Fundy and its tributary drainage. Most of these fish were thought to originate from the stocking program for coho initiated in the early 1970's in New Hampshire and Massachusetts, U.S.A. Successful spawning of coho in Bay of Fundy tributaries has occurred on at least three occasions, once in the Digdeguash River, N. B., and twice in the Cornwallis River, N. S. Electrofishing surveys during 1982 failed to capture any coho parr in 28 New Brunswick coastal Bay of Fundy streams. Nine coho parr were captured in the Cornwallis River in the fall of 1982 and five more the following spring.

    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.

In January 2008, the Province of Nova Scotia announced that Minas Basin Pulp and Power Co Ltd. had been awarded the opportunity to construct a tidal energy testing and research facility in the Minas Basin, known as the Fundy Tidal Energy Demonstration Facility. This Facility will be managed by a non-profit corporation called FORCE. The objectives of this study are twofold; - to undertake a broad MEKS study for the Bay of Fundy Phase I Area as it may relate to future renewable energy projects i.e. wind, tidal and wave, specifically in Phase 1 area of the Bay of Fundy ( as identified in MGC Proposal - Minas Channel and Minas Basin), and - to undertake a more focused MEKS review specific to the Fundy Tidal Energy Demonstration Project area which would consider the land and water area potentially affected by the project, identify what is the Mi’kmaq traditional use activity that has or is currently taking place within the Project Site and Study Area and what Mi’kmaq ecological knowledge presently exists in regards to the Project Site and Study Area.

  • The Evaluation of Wetland Restoration Potential Within the Cornwallis River Study Area
    The Evaluation of Wetland Restoration Potential within the Cornwallis River Study Area Report Prepared by: McCallum Environmental Ltd. 2 Bluewater Road, Suite 115 Bedford, Nova Scotia B4B 1G7 February 28, 2017 EXECUTIVE SUMMARY The purpose of this Evaluation of Wetland Restoration Potential (EWRP) study was to identify technically feasible and ecologically valuable options for future wetland restoration projects, as well as to identify potential areas suitable to detain and store water within a historically degraded watershed. The Study Area lies within the Cornwallis River Secondary Watershed, Nova Scotia. The Study Team identified a Study Area based on a select group of four tertiary watershed basins within land degraded by agricultural activity in the Cornwallis River Secondary Watershed. In Nova Scotia, the Department of Natural Resources owns and operates the Wetlands Inventory Database. This database is currently used to identify wetland habitat in Nova Scotia. However, it is commonly understood within industry and government that this database significantly underrepresents the quantity of wetlands throughout the province of Nova Scotia. Therefore, EWRP first identified and evaluated a Geographic Information Systems (GIS) tool, the potential wetland layer (PWL), to aid in the identification of potential wetland habitat and associated potential wetland restoration opportunities. This PWL was created for the defined Study Area within the Cornwallis River Secondary Watershed. In addition, a new drainage class layer recently developed by the Department of Natural Resources (NSDNR) was obtained, and integrated into the PWL for analysis. The drainage layer is based on the provincially available Wet Areas Mapping layer as modified by texture class (from CanSIS soil descriptions), and slope (derived from Digital Elevation Model layer) influences.
