Atlantic Herring Spawning and Breeding Areas in St. Lawrence Estuary

Literature review from 1977 to 1998 documents concentration areas, spawning sites, and breeding areas of Atlantic herring in the St. Lawrence Estuary. Data was extracted from the Fish Habitat Management Information System (FHAMIS) by Fisheries and Oceans Canada.

Use Cases

• Map spawning sites and breeding areas to identify critical fish habitat for conservation planning.
• Analyze concentration areas to inform marine spatial planning and fisheries management.
• Study larval retention areas to understand population dynamics and recruitment.

Strengths

• Data is based on a literature review spanning over 20 years (1977-1998).
• Provided by the authoritative government agency Fisheries and Oceans Canada.
• Available in multiple geospatial formats including ESRI REST, SHP, and CSV.

Limitations
