Upper Penobscot Penobscot Bay's larval & juvenile cod: key to restoring the GOM's inshore groundfishery

Larval Cod
Penobscot Bay's upper estuary is one of the key generators of juvenile Atlantic cod for the Gulf of Maine . The ecological health of those waters is vital to the restoration of coastal cod schools to  healthy  levels .

Learn below about  the life and times of this very vulnerable stage of our atlantic cod.

"In its first few months as a juvenile cod, the survival rate increases by 17,000 times if the the cod settles into an eelgrass bed."

Larval cod eat softbodied protozoans until their jaws develop. Learn about this little known part of the Penobscot Bay's foodweb:the  microbes
