Summary

[edit]
Description
English: North Attleboro, MA, June 2012: Hatchery manager Larry Lofton shows Deputy Regional Director Deborah Rocque a control box next to a pool used for tank spawning at North Attleboro National Fish Hatchery.


Fish biologists capture adult shad from the Merrimack and Connecticut Rivers and transport them to the hatchery where tank spawning occurs. The fertilized eggs flow through a drain to a control box where they are collected and placed into egg cylinders hung around tanks. When the shad larvae hatch in about 4 days, they swim into the tanks through chutes at the top of the cylinders. The larvae are marked with oxytetracycline and released after a few days, for a turnaround time of about a week from egg to release in the Merrimack and Charles Rivers.

In 2012, the hatchery quadrupled past production for a projected total of 7-8 million shad. Credit: Catherine J. Hibbard/USFWS
