The Department of Fisheries established a survey of demersal juvenile Atlantic cod (*Gadus morhua*) in the nearshore (<10 m deep) in 1959. This survey aimed to characterize the distribution and abundance of juvenile Atlantic cod and was based upon Norway's Flodevigen sampling program which has been conducted continuously since 1919. A 25 m seine was used to sample juvenile Atlantic cod nursery locations on the Avalon Peninsula and Northeast coast of the island of Newfoundland in September and October. The survey continued until 1964 and became known as the Fleming survey, after original initiator Alistair Fleming. The survey was reinstated by Memorial University of Newfoundland from 1992 to 1997. Multiple tows were conducted at a subset of the original 55 Fleming sites located in St. Mary's Bay, Trepassey Bay, the Southern Shore, Conception Bay, Trinity Bay, Bonavista Bay, Gander Bay, New World Island, Fortune Harbour, Badger Bay, Halls Bay and Green Bay.This data set includes several different subsets, some of which span both Fleming Survey periods (1959-1964 and 1992-1997):I. JuvCodCatch60s90s:Catches of juvenile Atlantic cod (1959-1964, 1992-1997) from the first two consecutive tows at each site. This is a summary based on JuvCodLengths90s and FlemingSurveyData60s;II. JuvCodLength90s:Lengths of all individual juvenile Atlantic cod caught for each site (1992-1997);III. SiteEnvData60s90s:Station data for Fleming data 1992-1997;IV. FlemingSurveyData60s:Fleming survey data from 1959-1964 (note there are three record types pertaining to: station data "type 1"; general species catch data including juvenile Atlantic cod grouped by age class ("1+", "Zeroes", and "Total") "type 2; and juvenile Atlantic cod (species 223) listed in length bins "type 3"; andV. FlemingBycatch60s92to96:Bycatch data from 1959-1964 & 1992-1996 from first two tows at each site. This is a summary based partly on the FlemingSurveyData60s set.

Bay-scale empirical demonstrations of how bivalve aquaculture alters plankton composition, and subsequently ecological functioning and higher trophic levels, are lacking. Temporal, inter- and within-bay variation in hydrodynamic, environmental, and aquaculture pressure limit efficient plankton monitoring design to detect bay-scale changes and inform aquaculture ecosystem interactions. Here, we used flow cytometry to investigate spatio-temporal variations in bacteria and phytoplankton (< 20 µm) composition in four bivalve aquaculture embayments. We observed higher abundances of bacteria and phytoplankton in shallow embayments that experienced greater freshwater and nutrient inputs. Depleted nutrient conditions may have led to the dominance of picophytoplankton cells, which showed strong within-bay variation as a function of riverine vs freshwater influence and nutrient availability. Although environmental forcings appeared to be a strong driver of spatio-temporal trends, results showed that bivalve aquaculture may reduce near-lease phytoplankton abundance and favor bacterial growth. We discuss aquaculture pathways of effects such as grazing, benthic-pelagic coupling processes, and microbial biogeochemical cycling. Conclusions provide guidance on optimal sampling considerations using flow cytometry in aquaculture sites based on embayment geomorphology and hydrodynamics.Cite this data as: Sharpe H, Lacoursière-Roussel A, Barrell J (2024).

These data sets provide information pertaining to epifauna taxa including bottom-dwelling shrimp and fish along trawling transects in Bones Bay and Turnour Bay between 2001 and 2002. Data sets were compiled and formatted by Meagan Mak.Abstract from the report:This study is a component of a larger project designed to assess potential effects of shrimp trawling gear on epifauna, shrimp, fish, and benthic habitat of Clio Channel located in Broughton Archipelago, British Columbia, Canada. Replicate beam-trawl surveys were carried out on individual transects in both Bones Bay and Turnour Bay located in the northern and southern portions of Clio Channel, respectively. A submersible, towed video-camera surveyed the seabed to enumerate epifauna and fish taxa before and after trawling activities. In regards to the video surveys, fish and epifauna (e.g. common shrimp) were observed across Clio Channel, while sea whips were predominate in the Turnour Bay video transects.

This project was completed by the Salmonids Section in the Newfoundland and Labrador Science Branch of Fisheries and Oceans Canada (DFO). The Coastal Environmental Baseline Program has supported efforts in 2018 and 2019 of tagged Atlantic salmon smolts leaving the Bay de L’eau River and Rushoon River region of Placentia Bay. This was part of a larger four year tracking study in this region (2018, 2019, 2021, 2022) trying to improve DFO’s understanding of the residency, survival, and migration routes of Atlantic salmon smolts during the first months at sea within northwest Placentia Bay. As of spring 2023, four years of detection data were being processed with the goal of presenting this work at the next Atlantic salmon CSAS meeting and developing a primary publication. This record contains the locations there smolt were tagged in Placentia Bay, NL.

Between 2001 and 2004 a descriptive and comparative investigation of the benthic macro-infauna in 17 pockmarks and 10 reference locations outside pockmarks in Passamaquoddy Bay-Bay of Fundy- was made. This dataset contains the locations of the grab samples for each pockmark in the study area, the taxon abundance identified in each sample and the georeferenced video transect from 2004 using a towcam- an underwater, bottom referencing vehicle on which floodlights, analogue video- and digital still-camera were mounted.For more information of the data: Wildish DJ, Akagi HM, McKeown DL, Pohle GW (2008) Pockmarks influence benthic communities in Passamaquoddy Bay, Bay of Fundy, Canada.

These data sets provide information pertaining to shrimp and bycatch estimates associated with beam-trawling and trapping (2001-2002) in Clio Channel. Data sets were compiled and formatted by Meagan Mak.Abstract from report:As part of a project investigating possible modification of marine ecosystems by shrimp trawling and trapping, we enumerated beam trawl and prawn trap catches at two locations in Clio Channel, south -central coast of British Columbia. Beam trawl surveys were conducted in Bones Bay and Turnour Bay during October 2001 and January 2002, respectively, and a prawn trap survey was conducted in Turnour Bay during March 2002. Catch data from the two gear types are presented.

The project (Quoddy Region Pelagics Telemetry) will support the assessment of the effects of aquaculture on the distribution and abundance of pelagic fishes (salmon, mackerel, herring) and large predators (shark, marine mammals) in Passamaquoddy Bay and the Bay of Fundy, an area of intense finfish culture. An acoustic receivers network is placed yearly (from April to December) across various passageways, locations of project-specific interest, and at aquaculture sites in the region. Tagged pelagic species will be tracked through the network to provide information on migration routes, movement speed, survival rates and suspected predators, and determine interaction and residence at aquaculture sites. The network was utilized for monitoring the passage of: hatchery-reared wild salmon (n=340) released in the Magaguadavic River in 2018, 2019 and 2021, wild alewives (n=30) from the St. Croix River in 2021, and farmed Atlantic salmon released in the wild (n=99) in 2021. The receiver network has more recently supported adjacent projects on the use of the region by white shark and porbeagle as well as the residence of mackerel, herring, and sculpin at farm sites. The receivers additionally support other researchers with detection of striped bass, Inner Bay of Fundy Atlantic salmon, sturgeon, and many other species. Placement of the network will continue into 2025 inclusive with the longer-term goal to eventually deploy an array covering the entrance to the Bay of Fundy.Cite this data as: Trudel, M., Wilson, B., Black, M. 2023.

Fisheries and Oceans Canada (DFO) has worked with partners and ocean users to develop a draft conservation network plan for the Scotian Shelf-Bay of Fundy Bioregion. This work led to the 2017 draft conservation network plan. The draft plan was updated after targeted consultations from 2021 to 2022. The latest draft reflects new science information on climate change, updated human-use activities (such as fisheries data), and feedback from consultations.This dataset includes the latest existing and proposed conservation sites in the Scotian Shelf-Bay of Fundy Bioregion. Existing sites:-Marine Protected Areas (MPAs)-Marine refuges-Migratory bird sanctuary, National Wildlife area and National Park with marine componentsProposed sites:-Areas of Interest (AOIs) and their lead agency-Tier 1 sites are a higher priority for implementation because of their ecological characteristics and/or feasibility considerations, such as interest from Rightsholders, other levels of government, marine users and stakeholders. Some of these sites could be selected for advancement by 2030. The lead federal agency is specified for most Tier 1 sites.-Tier 2 sites are also important contributions to the conservation network, but will not be considered for advancement by 2030. Most of these sites require more research and information on ecological features and human uses before implementation.Proposed conservation sites:1 Cobequid Bay2 Southern Bight3 Chignecto Bay4 Salmon Rivers5 Bay of Fundy Horse Mussel Aggregations6 Maces Bay7 Deadmans Harbour8 Bocabec Bay – Midjic Bluff9 Oak Bay10 Tongue Shoal11 Pendleton – Little L’Etete Passage12 Simpsons Island – White Horse Island13 Head Harbour Passage14 Western Passage North15 Western Passage South16 South Campobello17 The Wolves – Wolves Bank18 Northwest Grand Manan19 Long Island Bay – Great Duck Island20 North of Nantucket Island21 Grand Harbour22 Seal Cove – Long Pond Bay23 Southern Head24 Three Islands25 Old Proprietor Shoal – The Prong26 Brier Island27 Lurcher Shoal28 Chebogue29 Eel Bay30 McNutts Island31 Pemsɨk32 LaHave Islands33 Sambro Ledges – Prospect34 Martinique Beach and Musquodoboit Harbour35 St. Mary’s (Napu’saqnuk) River and Estuary36 Country Island37 Canso Ledges – Sugar Harbour Islands38 MacNamaras Island39 Fleur-de-Lis Coast40 Bird Islands41 Ingonish Bays42 Aspy Bay43 Bras d’Or Lake44 Southwest Bank45 Western Jordan Basin46 Georges Bank47 LaHave Basin48 Scotian Gulf49 Central Scotian Slope, Rise and Abyss50 Emerald Basin Extension51 Inner Shelf Sea Pen Field52 Sable Island Bank North53 Sable Island Bank South54 Logan Canyon55 Canso Bank and Channels56 Misaine Bank and Laurentian Channel57 Eastern Shoal58 Cold SeepsBoundaries are preliminary and subject to change following public consultation.
