AIS NL Biofouling Species Fisheries and Oceans Canada's (DFO) National Marine Biofouling Monitoring Program conducts annual field surveys to monitor the introduction, establishment, spread, species richness, and relative abundance of native and some non-native species in Newfoundland and Labrador (NL) Region since 2006. Standardized monitoring protocols employed by DFO's NL, Maritimes, Gulf, and Quebec regions include biofouling collector plates deployed from May to October at georeferenced intertidal and shallow subtidal sites, including public docks, and public and private marinas and nautical clubs. Initially, (2006-2017), the collectors consisted of three 10 cm by 10 cm PVC plates deployed in a vertical array and spaced approximately 40 cm apart, with the shallowest plate suspended at least 1 m below the surface to sample subtidal and shallow intertidal species (McKenzie et al 2016a). Three replicate arrays were deployed at least 5 m apart per site. Since 2018, collector networks have been modified to improve statistical replication, including up to 10 individual collectors deployed per site at 1 m depth and at least 5 m apart (as above) from May to October. Since 2006, seven invasive biofouling organisms have been detected in Newfoundland and Labrador harbours, marinas and coastal areas.Should be cited as follows: DFO Newfoundland and Labrador Region Aquatic Invasive Species Marine Biofouling Monitoring Program.

Various mitigation measures (McKenzie et al. 2016b) contained this invasive tunicate to a small area for six years within Placentia Bay. First detected in Fortune Bay as an established population in 2019, increasing reports of the Vase tunicate have been made along the south coast of Newfoundland. The data provided here indicates the detections of this AIS in coastal NL.From 2018-2022, the Coastal Environmental Baseline Program provided additional support to enhance sampling efforts in Placentia Bay.

Harbour seals reside throughout the year around Newfoundland and Labrador (NL). The first systematic survey for harbour seals occurred along the NL Shelf during July and August 2021 to obtain counts of hauled out individuals and assess distribution. Grey seals are seasonal residents in NL, mainly present in the summer and autumn months. Grey seals were also recorded during the survey as these two species can share haul-out locations. Surveys were flown along the coastline with a Bell 429 helicopter with photographs taken of hauled out seals. This data includes the counts of hauled out harbour, grey and unknown seals seen during the survey. Adjusted counts are also provided, which assign the unknown seals to species based on the number of positively identified harbour and grey seals from each survey day. The realized survey coverage (survey tracks) is also included. Cite this data as: Hamilton, C.D., Goulet, P.J., Stenson, G.B., and Lang, S.L.C. 2024.

This colonial tunicate forms irregular shaped colonies usually of a solid color (orange, purple, yellow or cream). It is currently found in relatively small colonies in four harbours in NL; Placentia Bay (1), Fortune Bay (1), Conception Bay (1) and the west coast of NL (2).

Fisheries and Oceans Canada (DFO), in partnership with other government organizations, indigenous groups, and community stakeholders, monitor the migratory return of Atlantic salmon to rivers each season. In Newfoundland and Labrador, there are 15 management areas, known as Salmon Fishing Areas (SFAs), with over 400 rivers containing populations of spawning salmon. Each year, salmon populations are enumerated at monitoring facilities (counting fences or fishways) on several rivers throughout the province. Monitoring begins in April or May for the downstream smolt run and in June or July for the upstream adult run and varies in timing by year and river. Not all rivers are monitored annually and years with incomplete data are often attributable to environmental factors that delay or stop monitoring during a season (e.g. fence washout due to elevated water levels). Days with zero counts can be attributable to no fish and/or closures to the monitoring facility. While monitoring facilities are used primarily to count Atlantic salmon, other freshwater fish may also be enumerated if encountered. The counts from these monitoring facilities, in addition to angling information and other monitoring activities, provide information for estimating returns for the annual stock assessment, which is an important part of conservation and management of Atlantic salmon populations in Newfoundland and Labrador. This data contains information for Atlantic salmon only.

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.

It was reported in Argentia by the US Navy around 1945. It was found in 2006 on wharf structures in Argentia, Placentia Bay during the first AIS survey (Callahan et al 2010). This colonial tunicate is recognized by it star shaped grouping of individuals within the colony. It is currently found in Placentia Bay, Fortune Bay, St. Mary’s Bay, Conception Bay and the west coast of NL.

Proxied dataset of inshore lobster commercial fishing for 2012 - 2021 in the Newfoundland and Labrador region. Only lobster harvested from the Newfoundland and Labrador region are included, based on species sought.Commercial data for the inshore lobster fishery does not require a set of coordinates be provided for catch records. With zero georeferenced inshore lobster records, the inshore lobster fishery leaves a major data gap in one of Newfoundland and Labradors largest fisheries. The Gulf region created a lobster proxy mapping tool, which associated each commercial lobster record with the most likely 10km2 hexagon grid cell based on a number of weighted variables. The tool was adopted by the Newfoundland and Labrador region and altered to work with its own variables which include human use, habitat, accessibility, area/location, home port distance, traditional ecological knowledge and depth. Each hexagon represents the summed total weight of all records associated with a particular hexagon.The best available commercial data used in this model is derived from landings data and may not include catches that have resulted in cash/wharf sales. As a result, there are some areas of Newfoundland and Labrador that may be under represented in this dataset where wharf sales may be high. Therefore, this dataset should be viewed as a general estimation on lobster harvesting patterns within Newfoundland and Labrador.

This project was completed by the Groundfish Section in the Newfoundland and Labrador Science Branch of Fisheries and Oceans Canada (DFO). From 2018 to 2020, 14 year-round, acoustic receivers were deployed in Placentia Bay as a part of the Coastal Environmental Baseline Program to form 4 gates: Bar Haven (2 receivers), Centre Channel (1 receiver), Eastern Channel (6 receivers), and Western Channel (5 receivers). Additionally, 162 transmitters were deployed in Atlantic cod in the 3Ps region (2019-2022). Over the deployment period these receivers recorded a total of 2 094 024 detections from 63 unique transmitters including 45 Cod tagged through the Groundfish acoustic telemetry program. Most cod detected were tagged in Placentia Bay (43 fish) and many were detected at multiple receivers or multiple years (37 fish). Passive data collection for this project may extend up to 2030. This record contains the locations of the acoustic receivers in Placentia Bay, NL.
