Marine Aquaculture: Raising Saltwater Fish in Your Classroom. Teacher Edition

摘要

Massachusettes has a historical connection to the sea, which began even beforethe first European settlement at Plymouth. The ocean waters off New England were rich with fish that were important enough for European fishermen to travel across the ocean to collect what they could and bring it back to Europe. This harvest included an amazing amount and variety of fish from the sea. Many of these species have seen so important that we have named many places and roads after them: Cape Cod, Halibut Point, Alewife Brook Parkway and Herring Cove. The ocean and the fish that live there are in jeopardy. Pollution from our cities and towns, and from individual homes, has increased the amount of chemicals and bacteria in our waters to levels that prevent swimming, fishing or shellfishing in these areas. Some of these materials cause changes in habitat so that animals and plants that once lived there can no longer survive.
