Barriers to Fish Passage in Nova Scotia the Evolution of Water Control Barriers in Nova Scotia’S Watershed
Dalhousie University- Environmental Science Barriers to Fish Passage in Nova Scotia The Evolution of Water Control Barriers in Nova Scotia’s Watershed By: Gillian Fielding Supervisor: Shannon Sterling Submitted for ENVS 4901- Environmental Science Honours Abstract Loss of connectivity throughout river systems is one of the most serious effects dams impose on migrating fish species. I examine the extent and dates of aquatic habitat loss due to dam construction in two key salmon regions in Nova Scotia: Inner Bay of Fundy (IBoF) and the Southern Uplands (SU). This work is possible due to the recent progress in the water control structure inventory for the province of Nova Scotia (NSWCD) by Nova Scotia Environment. Findings indicate that 586 dams have been documented in the NSWCD inventory for the entire province. The most common main purpose of dams built throughout Nova Scotia is for hydropower production (21%) and only 14% of dams in the database contain associated fish passage technology. Findings indicate that the SU is impacted by 279 dams, resulting in an upstream habitat loss of 3,008 km of stream length, equivalent to 9.28% of the total stream length within the SU. The most extensive amount of loss occurred from 1920-1930. The IBoF was found to have 131 dams resulting in an upstream habitat loss of 1, 299 km of stream length, equivalent to 7.1% of total stream length. The most extensive amount of upstream habitat loss occurred from 1930-1940. I also examined if given what I have learned about the locations and dates of dam installations, are existent fish population data sufficient to assess the impacts of dams on the IBoF and SU Atlantic salmon populations in Nova Scotia? Results indicate that dams have caused a widespread upstream loss of freshwater habitat in Nova Scotia howeverfish population data do not exist to examine the direct impact of dam construction on the IBoF and SU Atlantic salmon populations in Nova Scotia. -

The Lady Crab (Ovalipes ocellatus), mainly found south of Cape Cod and in the southern Gulf of St. Lawrence, is reported from an ocean beach on the north shore of Massachusetts Bay (42°28'60"N, 70°46'20"W) in the Gulf of Maine. All previ- ously known Gulf of Maine populations north of Cape Cod Bay are estuarine and thought to be relicts of a continuous range during the Hypsithermal. The population reported here is likely a recent local habitat expansion. Key Words: Lady Crab, Ovalipes ocellatus, Gulf of Maine, distribution.

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. -

FALL 2012/ Winter 2013 THE NEWSLETTER OF MAINE RIVERS ST. CROIX RIVER UPDATE Joint Tribal Council of the Passamaquoddy Tribe passes St. Croix River Alewife Resolution Citing the vital linkages that sea-run alewives create in the food chain of the St. Croix River, Passamaquoddy Bay and the Bay of Fundy, members of the Joint Tribal Council of the Passamaquoddy Tribe voted unanimously to pass a resolution that calls for reopening the St. Croix Rivers for alewives. !e resolution states that sea-run alewife are a vital link in the food chain of the St. Croix River that sustained the Passamaquoddy for thousands of years, “without which we may not have survived.” !e Joint Tribal Council resolution supports the June 14, 2012 Passamaquoddy Chief’s Declaration of a State of Emergency within the St. Croix River, and calls for overturning Maine’s 1995 law that blocks alewives from the St. Croix. In early June 2012 members of the Schoodic Riverkeepers advanced the Passamaquoddy river restoration e"ort with a 100-mile sacred run up the St. Croix River, a run that mirrored the annual trek of native alewives. !e route extended from Pleasant Point, near Eastport, to Mud Lake Stream, a 4,000-year-old ancestral #shing site for the Passamaquoddy at the head of Spednic Lake. Maine Rivers has been working for nearly a decade on advocacy e"orts to reopen the St. Croix River and applauds this recent decision of the Joint Tribal Council.

Annapolis Basin Bay of Fundy Estuary Profile Annapolis Basin
Bay of Fundy Estuary Profiles Annapolis Basin Bay of Fundy Estuary Profile Annapolis Basin The Annapolis Basin is a sub-basin of the Bay of Fundy along the northwestern shore of Nova Scotia and at the western end of the Annapolis Valley. The Annapolis River is the major water source flowing into the estuary. At the NB mouth of the estuary, a narrow channel known as the Digby Gut connects the 44 NS estuary to the Bay of Fundy. Annapolis Royal and Digby are the main communities along the shore of the estuary, and Kingston-Greenwood is within the catchment area. Near Digby, there is a ferry port that connects to Saint John, New Brunswick. The estuary also hosts a tidal power generating station, which is near Annapolis Royal. The economy within the catchment area is largely driven by agriculture. However, Estuary surface area 104.07 km2 there are also several shellfish and finfish aquaculture tenures, and some Width at estuary mouth 1.85 km commercial fisheries near the mouth of the estuary that largely target Shoreline length 200.63 km invertebrates such as crab, lobster, and clams that inhabit tidal mudflats.
